  • Plant Trait Networks: Improved Resolution of the Dimensionality of Adaptation
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-06-25
    Nianpeng He; Ying Li; Congcong Liu; Li Xu; Mingxu Li; Jiahui Zhang; Jinsheng He; Zhiyao Tang; Xingguo Han; Qing Ye; Chunwang Xiao; Qiang Yu; Shirong Liu; Wei Sun; Shuli Niu; Shenggong Li; Lawren Sack; Guirui Yu

    Functional traits are frequently used to evaluate plant adaptation across environments. Yet, traits tend to have multiple functions and interactions, which cannot be accounted for in traditional correlation analyses. Plant trait networks (PTNs) clarify complex relationships among traits, enable the calculation of metrics for the topology of trait coordination and the importance of given traits in PTNs

  • Promoting Individual and Collective Creativity in Science Students
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-06-21
    Isabel Reche; Francisco Perfectti

    Creativity is a scientific skill necessary to develop a successful research career. We expose the importance of a growth mindset, divergent, lateral, and associative thinking, serendipity, and being part of a nonhierarchical and diverse research team to improve both individual and collective creativity.

  • Disease-mediated ecosystem services: Pathogens, plants, and people.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-06-15
    Rachel E Paseka,Lauren A White,Dedmer B Van de Waal,Alex T Strauss,Angélica L González,Rebecca A Everett,Angela Peace,Eric W Seabloom,Thijs Frenken,Elizabeth T Borer

    Despite the ubiquity of pathogens in ecological systems, their roles in influencing ecosystem services are often overlooked. Pathogens that infect primary producers (i.e., plants, algae, cyanobacteria) can have particularly strong effects because autotrophs are responsible for a wide range of provisioning, regulating, and cultural services. We review the roles of pathogens in mediating ecosystem services

  • Living Litter: Dynamic Trait Spectra Predict Fauna Composition.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-06-07
    Saori Fujii,Matty P Berg,Johannes H C Cornelissen

    Understanding what drives soil fauna species composition through space and time is crucial because we should preserve soil fauna biodiversity and its key role in ecosystem functioning in this era of fast environmental change. As plant leaf litter provides both food and habitat for soil fauna, a focus on litter traits that relate to these two functions will help in understanding soil invertebrate community

  • Does Plasticity Trade Off With Basal Heat Tolerance?
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-06-05
    Belinda van Heerwaarden,Vanessa Kellermann

    Studies suggest that many species are already living close to their upper physiological thermal limits. Phenotypic plasticity is thought to be an important mechanism for species to counter rapid environmental change, yet the extent to which plastic responses may buffer projected climate change – and what limits the evolution of plasticity – is still unclear. The tolerance–plasticity trade-off hypothesis

  • COVID-19, Health, Conservation, and Shared Wellbeing: Details Matter.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-06-04
    Robert A Montgomery,David W Macdonald

    Many have stridently recommended banning markets like the one where COVID-19 originally spread. We highlight that millions of people around the world depend on markets for subsistence and the diverse use of animals globally defies uniform bans. We argue that the immediate and fair priority is critical scrutiny of wildlife trade.

  • Multilevel Organisation of Animal Sociality.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-05-27
    Cyril C Grueter,Xiaoguang Qi,Dietmar Zinner,Thore Bergman,Ming Li,Zuofu Xiang,Pingfen Zhu,Andrea Bamberg Migliano,Alex Miller,Michael Krützen,Julia Fischer,Daniel I Rubenstein,T N C Vidya,Baoguo Li,Maurício Cantor,Larissa Swedell

    Multilevel societies (MLSs), stable nuclear social units within a larger collective encompassing multiple nested social levels, occur in several mammalian lineages. Their architectural complexity and size impose specific demands on their members requiring adaptive solutions in multiple domains. The functional significance of MLSs lies in their members being equipped to reap the benefits of multiple

  • Photic Barriers to Poleward Range-shifts.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-05-27
    Nicholas Per Huffeldt

    With climate warming, organisms are shifting their ranges towards the poles, tracking their optimal thermal environments. Day-length, the driver of daily and annual timing, is, however, fixed by latitude and date. Timing and photoreception mechanisms adapted to ancestral photic environments may restrict range-shift capacity, resulting in photic barriers to range-shifts.

  • Taking the Animals' Perspective Regarding Anthropogenic Underwater Sound.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-05-25
    Arthur N Popper,Anthony D Hawkins,Frank Thomsen

    Anthropogenic (man-made) sound has the potential to harm marine biota. Increasing concerns about these effects have led to regulation and mitigation, despite there being few data on which to base environmental management, especially for fishes and invertebrates. We argue that regulation and mitigation should always be developed by looking at potential effects from the perspectives of the animals and

  • You're Just My Type: Mate Choice and Behavioral Types.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-05-22
    Amelia A Munson,Cameron Jones,Hannes Schraft,Andrew Sih

    Consistent individual differences in behavior [i.e., behavioral types (BTs)], are common across the animal kingdom. Consistency can make behavior an adaptive trait for mate choice decisions. Here, we present a conceptual framework to explain how and why females might evaluate a male’s BT before mating. Because BTs are consistent across time or context, a male’s BT can be a reliable indicator of his

  • Invasion Science and the Global Spread of SARS-CoV-2.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-05-19
    Martin A Nuñez,Anibal Pauchard,Anthony Ricciardi

    Emerging infectious diseases like COVID19 are driven by ecological and socioeconomic factors, and their rapid spread and devastating impacts mirror those of invasive species. Collaborations between biomedical researchers and ecologists, heretofore rare, are vital to limiting future outbreaks. Enhancing the cross-disciplinary framework offered by invasion science could achieve this goal.

  • Pulse Heat Stress and Parasitism in a Warming World.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-05-18
    Danielle C Claar,Chelsea L Wood

    Infectious disease outbreaks emerged across the globe during the recent 2015-2016 El Niño event, re-igniting research interest in how climate events influence disease dynamics. While the relationship between long-term warming and the transmission of disease-causing parasites has received substantial attention, we do not yet know how pulse heat events - common phenomena in a warming world - will alter

  • The Importance of Genetic Redundancy in Evolution.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-05-18
    Áki J Láruson,Sam Yeaman,Katie E Lotterhos

    Genetic redundancy has been defined in many different ways at different levels of biological organization. Here, we briefly review the general concept of redundancy and focus on the evolutionary importance of redundancy in terms of the number of genotypes that give rise to the same phenotype. We discuss the challenges in determining redundancy empirically, with published experimental examples, and

  • Standardizing Ecosystem Morphological Traits from 3D Information Sources.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-05-15
    R Valbuena,B O'Connor,F Zellweger,W Simonson,P Vihervaara,M Maltamo,C A Silva,D R A Almeida,F Danks,F Morsdorf,G Chirici,R Lucas,D A Coomes,N C Coops

    3D-imaging technologies provide measurements of terrestrial and aquatic ecosystems' structure, key for biodiversity studies. However, the practical use of these observations globally faces practical challenges. First, available 3D data are geographically biased, with significant gaps in the tropics. Second, no data source provides, by itself, global coverage at a suitable temporal recurrence. Thus

  • Analogies for a No-Analog World: Tackling Uncertainties in Reintroduction Planning.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-05-13
    ElizabethS Forbes,Peter S Alagona,Andrea J Adams,Sarah E Anderson,Kevin C Brown,Jolie Colby,Scott D Cooper,Sean M Denny,Elizabeth H T Hiroyasu,Robert Heilmayr,Bruce E Kendall,Jennifer A Martin,Molly Hardesty-Moore,Alexis M Mychajliw,Brian P Tyrrell,Zoë S Welch

    Species reintroductions involve considerable uncertainty, especially in highly altered landscapes. Historical, geographic, and taxonomic analogies can help reduce this uncertainty by enabling conservationists to better assess habitat suitability in proposed reintroduction sites. We illustrate this approach using the example of the California grizzly, an iconic species proposed for reintroduction.

  • Plant Secondary Compounds in Soil and Their Role in Belowground Species Interactions.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-05-12
    Bodil K Ehlers,Matty P Berg,Michael Staudt,Martin Holmstrup,Marianne Glasius,Jacintha Ellers,Sara Tomiolo,René B Madsen,Stine Slotsbo,Josep Penuelas

    Knowledge of the effect of plant secondary compounds (PSCs) on belowground interactions in the more diffuse community of species living outside the rhizosphere is sparse compared with what we know about how PSCs affect aboveground interactions. We illustrate here that PSCs from foliar tissue, root exudates, and leaf litter effectively influence such belowground plant-plant, plant-microorganism, and

  • The Persistence of Polymorphisms across Species Radiations.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-05-11
    Gabriel A Jamie,Joana I Meier

    Studies on polymorphisms have been foundational to our understanding of evolution. The presence of different phenotypic morphs is sometimes considered a precursor to speciation in which morphs evolve into different species. While speciation should initially reduce genetic variation in daughter versus parental species, a common pattern is the recurrence of the same phenotypic polymorphism in many species

  • Towards a Comparative Framework of Demographic Resilience.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-05-07
    Pol Capdevila,Iain Stott,Maria Beger,Roberto Salguero-Gómez

    In the current global biodiversity crisis, developing tools to define, quantify, compare, and predict resilience is essential for understanding species' responses to global change. Disparate interpretations of resilience have, however, hampered the development of a common currency to quantify and compare resilience across natural systems. Most resilience frameworks focus on upper levels of biological

  • Artificial Intelligence Accidentally Learned Ecology through Video Games.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-05-07
    Lou Barbe,Cendrine Mony,Benjamin W Abbott

    An advanced artificial intelligence (AI) system defeated the best human players in StarCraft II, a popular real-time strategy game. In a virtual ecosystem, players compete for habitats and resources, unintentionally reproducing many ecological phenomena. We propose to repurpose this AI to test ecological hypotheses that have been intractable using traditional approaches.

  • On the Three Major Recycling Pathways in Terrestrial Ecosystems.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-05-04
    Juli G Pausas,William J Bond

    Plants are the largest biomass component of most terrestrial ecosystems, and litter decomposition is considered the dominant process by which nutrients return to plants. We show that in terrestrial ecosystems, there are three major pathways by which plant biomass is degraded into forms that release nutrients again available to plants: microbial decomposition; vertebrate herbivory; and wildfires. These

  • Are Environmental DNA Methods Ready for Aquatic Invasive Species Management?
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-05-01
    Adam J Sepulveda,Nanette M Nelson,Christopher L Jerde,Gordon Luikart

    Multiple studies have demonstrated environmental (e)DNA detections of rare and invasive species. However, invasive species managers struggle with using eDNA results because detections might not indicate species presence. We evaluated whether eDNA methods have matured to a point where they can be widely applied to aquatic invasive species management. We have found that eDNA methods meet legal standards

  • The Nidobiome: A Framework for Understanding Microbiome Assembly in Neonates.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-04-29
    Felipe Campos-Cerda,Brendan J M Bohannan

    The importance of microbial associations to animals’ development, physiology, and fitness is widely recognized. In most animals, these microbial associations must be developed anew with every generation, making microbiome assembly a critical ecological and evolutionary process. To fully understand neonate microbial colonization, we need to study the interacting effects of neonate, parents, nest, and

  • Imminent Extinction of Australian Myrtaceae by Fungal Disease.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-04-25
    Roderick J Fensham,Angus J Carnegie,Boris Laffineur,Robert O Makinson,Geoff S Pegg,Jarrah Wills

    Myrtle rust is a fungal disease that has spread rapidly across the globe, arriving in Australia in 2010. The tree species Rhodomyrtus psidioides is nearly extinct in the wild as a result of the disease, leading to potential disruption of ecosystem function. Many other Myrtaceae may also be threatened and unprecedented impacts of the disease are predicted.

  • Nutritional Dimensions of Invasive Success
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-04-21
    Jonathan Z. Shik; Audrey Dussutour

    Despite mounting calls for predictive ecological approaches rooted in physiological performance currencies, the field of invasive species biology has lagged behind. For instance, successful invaders are often predicted to consume diverse foods, but the nutritional complexity of foods often leaves food-level analyses short of physiological mechanisms. The emerging field of nutritional geometry (NG)

  • iEcology: Harnessing Large Online Resources to Generate Ecological Insights.

    Digital data are accumulating at unprecedented rates. These contain a lot of information about the natural world, some of which can be used to answer key ecological questions. Here, we introduce iEcology (i.e., internet ecology), an emerging research approach that uses diverse online data sources and methods to generate insights about species distribution over space and time, interactions and dynamics

  • Volant Fossil Vertebrates: Potential for Bioinspired Flight Technology.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-04-09
    Elizabeth Martin-Silverstone,Michael B Habib,David W E Hone

    Animal flight is ecologically important and has a long evolutionary history. It has evolved independently in many distantly related clades of animals. Powered flight has evolved only three times in vertebrates, making it evolutionarily rare. Major recent fossil discoveries have provided key data on fossil flying vertebrates and critical insights regarding the evolution and different arrangements of

  • A Roadmap for Understanding the Evolutionary Significance of Structural Genomic Variation.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-04-06
    Claire Mérot,Rebekah A Oomen,Anna Tigano,Maren Wellenreuther

    Structural genomic variants (SVs) are ubiquitous and play a major role in adaptation and speciation. Yet, comparative and population genomics have focused predominantly on gene duplications and large-effect inversions. The lack of a common framework for studying all SVs is hampering progress towards a more systematic assessment of their evolutionary significance. Here we (i) review how different types

    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-04-02
    Jiajia Liu; Ding Li Yong; Chi-Yeung Choi; Luke Gibson

    The world’s biomes and their associated ecosystems are artificially fractured by geopolitical boundaries that define countries. Yet ‘transboundary’ landscapes often overlap with biodiversity hotspots, contain surprisingly important ecosystems, and provide critical habitats for threatened species. Notwithstanding, biodiversity in these landscapes is increasingly imperiled by infrastructure, including

  • The Adaptive Value of Numerical Competence.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-03-30
    Andreas Nieder

    Evolution selects for traits that are of adaptive value and increase the fitness of an individual or population. Numerical competence, the ability to estimate and process the number of objects and events, is a cognitive capacity that also influences an individual’s survival and reproduction success. Numerical assessments are ubiquitous in a broad range of ecological contexts. Animals benefit from numerical

  • The Demographic Buffering Hypothesis: Evidence and Challenges.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-03-24
    Christoffer H Hilde,Marlène Gamelon,Bernt-Erik Sæther,Jean-Michel Gaillard,Nigel G Yoccoz,Christophe Pélabon

    In (st)age-structured populations, the long-run population growth rate is negatively affected by temporal variation in vital rates. In most cases, natural selection should minimize temporal variation in the vital rates to which the long-run population growth is most sensitive, resulting in demographic buffering. By reviewing empirical studies on demographic buffering in wild populations, we found overall

  • Phylogenetics is the New Genetics (for Most of Biodiversity).
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-03-21
    Stacey D Smith,Matthew W Pennell,Casey W Dunn,Scott V Edwards

    Despite substantial progress in understanding the genetic basis for differences in morphology, physiology, and behavior, many phenotypes of interest are difficult to study with traditional genetic approaches because their origin traces to deep nodes in the tree of life. Moreover, many species are not amenable to either large-scale sampling or laboratory crosses. We argue that phylogenetic methods and

  • Poaching is Not One Big Thing.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-03-20
    Robert A Montgomery

    Among science and society, poaching is often depicted as one big dark conservation problem. In actuality, there are three main categories of poaching, with innumerable subcategories, including trophy, medicative, and consumptive poaching. Recognition of the complexity of poaching is vital to the effective alignment of conservation practice and social justice.

  • Tropical Cyclone Ecology: A Scale-Link Perspective.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-03-18
    Teng-Chiu Lin,J Aaron Hogan,Chung-Te Chang

    Tropical cyclones are increasing in intensity and size and, thus, are poised to increase in importance as disturbance agents. Our understanding of cyclone ecology is biased towards the North Atlantic Basin, because cyclone effects do differ across oceanic basins. Cyclones have both short and long-term effects across the levels of biological organization, but we lack a scale‐perspective of cyclone ecology

  • Coevolutionary Governance of Antibiotic and Pesticide Resistance.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-03-17
    Peter Søgaard Jørgensen,Carl Folke,Patrik J G Henriksson,Karin Malmros,Max Troell,Anna Zorzet,

    Development of new biocides has dominated human responses to evolution of antibiotic and pesticide resistance. Increasing and uniform biocide use, the spread of resistance genes, and the lack of new classes of compounds indicate the importance of navigating toward more sustainable coevolutionary dynamics between human culture and species that evolve resistance. To inform this challenge, we introduce

  • On Deepest Caves, Extreme Habitats, and Ecological Superlatives.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-03-14
    Stefano Mammola

    In an environment where the impact of research is central, scientists face the dilemma of choosing between orthodox writing for objectivity and sensational writing to provoke interest. The use of superlatives in high-ranking ecology journals has increased significantly in recent years, a writing behavior that works against scientific objectivity.

  • Horizon Scan of the Belt and Road Initiative.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-03-12
    Alice C Hughes,Alex M Lechner,Alexander Chitov,Alexander Horstmann,Amy Hinsley,Angela Tritto,Anthony Chariton,Binbin V Li,Delfin Ganapin,Eugene Simonov,Katherine Morton,Kemel Toktomushev,Marc Foggin,May Tan-Mullins,Michael C Orr,Richard Griffiths,Richard Nash,Scott Perkin,Raphaël Glémet,Minsun Kim,Douglas W Yu

    The Belt and Road Initiative (BRI) represents the largest infrastructure and development project in human history, and presents risks and opportunities for ecosystems, economies, and communities. Some risks (habitat fragmentation, roadkill) are obvious, however, many of the BRI’s largest challenges for development and conservation are not obvious and require extensive consideration to identify.

    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-03-11
    Bernard M A G Piette,Jonathan G Heddle

    Evolution requires self-replication. But, what was the very first self-replicator directly ancestral to all life? The currently favoured RNA World theory assigns this role to RNA alone but suffers from a number of seemingly intractable problems. Instead, we suggest that the self-replicator consisted of both peptides and nucleic acid strands. Such a nucleopeptide replicator is more feasible both in

  • Agriculture and the Disruption of Plant-Microbial Symbiosis.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-03-10
    Stephanie S Porter,Joel L Sachs

    Domestication has transformed hundreds of wild plant species into productive cultivars for human utility. However, cultivation practices and intense artificial selection for yield may entail a hidden cost: the disruption of interactions between plants and beneficial microbiota. Here, we synthesize theory predicting that evolutionary trade-offs, genetic costs, and relaxed selection disrupt plant-microbial

  • Animals as Agents in Fire Regimes

    Claire N. Foster; Sam C. Banks; Geoffrey J. Cary; Christopher N. Johnson; David B. Lindenmayer; Leonie E. Valentine

    Fire is a powerful ecological and evolutionary force. Animals that modify drivers of fire behaviour could therefore have far-reaching effects on ecosystems. Yet, with a few notable exceptions, effects of animals on fire have been often overlooked. We show how animals can affect fire behaviour by modifying the amount, structure, or condition of fuel or, more rarely, by altering other controls on fire

  • Is Endothermy an Evolutionary By-Product?
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-03-05
    Frank Seebacher

    Endothermy alters the energetic relationships between organisms and their environment and thereby influences fundamental niches. Endothermy is closely tied to energy metabolism. Regulation of energy balance is indispensable for all life and regulatory pathways increase in complexity from bacteria to vertebrates. Increasing complexity of metabolic networks also increase the probability for endothermic

  • Climate Dipoles as Continental Drivers of Plant and Animal Populations.

    Benjamin Zuckerberg,Courtenay Strong,Jalene M LaMontagne,Scott St George,Julio L Betancourt,Walter D Koenig

    Ecological processes, such as migration and phenology, are strongly influenced by climate variability. Studying these processes often relies on associating observations of animals and plants with climate indices, such as the El Niño-Southern Oscillation (ENSO). A common characteristic of climate indices is the simultaneous emergence of opposite extremes of temperature and precipitation across continental

    Federico López-Osorio,Yannick Wurm

    Pollinators have been declining worldwide, and pesticides have contributed to these declines. High-resolution approaches from molecular medicine can provide unparalleled insight into organismal physiology and health. Applying these approaches to pollinators can significantly improve the efficiency and sensitivity of pesticide research and evaluation, and thus the sustainability of modern agriculture

  • Measuring Coevolutionary Dynamics in Species-Rich Communities.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-03-03
    Alex R Hall,Ben Ashby,Jordi Bascompte,Kayla C King

    Identifying different types of coevolutionary dynamics is important for understanding biodiversity and infectious disease. Past work has often focused on pairs of interacting species, but observations of extant communities suggest that coevolution in nature occurs in networks of antagonism and mutualism. We discuss challenges for measuring coevolutionary dynamics in species-rich communities, and we

    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-02-22
    Sarah L Crowley,Martina Cecchetti,Robbie A McDonald

    Cats share a long history with humans but are remarkable among domesticated species in largely retaining behavioural and reproductive independence from people. In many societies, the cat maintains liminal status as both a domestic and a wild animal. An adaptive push-and-pull between wild and domestic traits corresponds with dual roles as companions and pest controllers, and with conflicted treatment

  • Dispersal Reduction: Causes, Genomic Mechanisms, and Evolutionary Consequences.
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-02-22
    J M Waters,B C Emerson,P Arribas,G A McCulloch

    Recent biological analyses suggest that reductions in dispersal ability have been key drivers of diversification across numerous lineages. We synthesise emerging data to highlight similarities regarding the causes and consequences of dispersal reduction across taxa and ecosystems, as well as the diverse genomic mechanisms underpinning these shifts. Natural selection has acted on standing genetic variation

    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-02-18
    J Billington,R J Webster,T N Sherratt,R M Wilkie,C Hassall

    To survive and pass on their genes, animals must perform many tasks that affect their fitness, such as mate-choice, foraging, and predator avoidance. The ability to make rapid decisions is dependent on the information that needs to be sampled from the environment and how it is processed. We highlight the need to consider visual attention within sensory ecology and advocate the use of eye-tracking methods

    Simon T Segar,Tom M Fayle,Diane S Srivastava,Thomas M Lewinsohn,Owen T Lewis,Vojtech Novotny,Roger L Kitching,Sarah C Maunsell

    The structure of ecological networks reflects the evolutionary history of their biotic components, and their dynamics are strongly driven by ecoevolutionary processes. Here, we present an appraisal of recent relevant research, in which the pervasive role of evolution within ecological networks is manifest. Although evolutionary processes are most evident at macroevolutionary scales, they are also important

  • Embryo Selection and Mate Choice: Can 'Honest Signals' Be Trusted?
    Trends Ecol. Evol. (IF 14.764) Pub Date : 2020-01-27
    Dakota E McCoy,David Haig

    When a measure becomes a target, it often ceases to be a good measure - an effect familiar from the declining usefulness of standardized testing in schools. This economic principle also applies to mate choice and, perhaps surprisingly, pregnancy. Just as females screen potential mates under many metrics, human mothers unconsciously screen embryos for quality. 'Examinees' are under intense selection

    Observational and experimental studies have shown that an interaction class between two species (be it mutualistic, competitive, antagonistic, or neutral) may switch to a different class, depending on the biotic and abiotic factors within which species are observed. This complexity arising from the evidence of context-dependencies has underscored a difficulty in establishing a systematic analysis about

    Plant-animal interactions are fundamentally important in ecosystems, but have often been ignored by studies of climate-change impacts on biodiversity. Here, we present a trait-based framework for predicting the responses of interacting plants and animals to climate change. We distinguish three pathways along which climate change can impact interacting species in ecological communities: (i) spatial

    Mammalian colors and color patterns are some of the most diverse and conspicuous traits found in nature and have been widely studied from genetic/developmental and evolutionary perspectives. In this review we first discuss the proximate causes underlying variation in pigment type (i.e., color) and pigment distribution (i.e., color pattern) and highlight both processes as having a distinct developmental

    Statistics matter greatly in biology, whether we like it or not. As a discipline with an empirical inclination, we are faced with data every day and we rely on inferential statistical models to make sense of it and to provide us with novel insights. Much of the time, the growing level of complexity and sophistication of the models we put to use in ecology and evolution have led to more appropriate

    While the interplay between migration and adaptation dictates species response to climate change, technological limitations have obfuscated explicit tests on past adaptive responses. However, a surge in technology-driven advances in paleoecological methods coincides with breakthroughs in processing ancient DNA, providing the first opportunity to assess adaptation to past climate shifts.
