Mutualisms impact species' range expansion speeds and spatial distributions Ecology (IF 4.8) Pub Date : 2023-09-30 Naven Narayanan, Allison K. Shaw
Species engage in mutually beneficial interspecific interactions (mutualisms) that shape their population dynamics in ecological communities. Species engaged in mutualisms vary greatly in their degree of dependence on their partner from complete dependence (e.g. yucca and yucca moth mutualism) to low dependence (e.g. generalist bee with multiple plant species). While current empirical studies show

Demography of the understory herb Heliconia acuminata (Heliconiaceae) in an experimentally fragmented tropical landscape Ecology (IF 4.8) Pub Date : 2023-09-30 Emilio M. Bruna, Maria Uriarte, Maria Rosa Darrigo, Paulo Rubim, Cristiane F. Jurinitz, Eric R. Scott, Osmaildo Ferreira da Silva, W. John Kress
Habitat fragmentation remains a major focus of research by ecologists decades after being put forward as a threat to the integrity of ecosystems. While studies have documented myriad biotic changes in fragmented landscapes, including the local extinction of species from fragments, the demographic mechanisms underlying these extinctions are rarely known. However, many of them – especially in lowland

The unimodal intransitivity–fertility relationship is not mediated by demographic trade-offs in a subtropical forest Ecology (IF 4.8) Pub Date : 2023-09-28 Zhengliang Huang, Yuanzhi Li, Weitao Wang, Buhang Li, Wenqi Luo, Youshi Wang, Chengjin Chu
Intransitive competition has long been acknowledged as a potential mechanism favoring species coexistence. However, its prevalence, variance along environmental gradients, and possible underlying mechanisms (trade-offs) in plant communities (especially in forests) has seldomly been examined. A recently developed “reverse-engineering” approach based on Markov Chain allows us to estimate competitive

Biological invasions alter the structure of a tropical freshwater food web Ecology (IF 4.8) Pub Date : 2023-09-28 Diana M. T. Sharpe, Marisol P. Valverde, Luis F. De León, Andrew P. Hendry, Mark E. Torchin
Biological invasions are expected to alter food web structure, but there are limited empirical data directly comparing invaded versus uninvaded food webs, particularly in species-rich, tropical systems. We characterize for the first time the food web of Lake Gatun – a diverse and highly-invaded tropical freshwater lake within the Panama Canal. We used stable isotope analysis to reconstruct the trophic

Reconciling contrasting effects of nitrogen on host immunity and pathogen transmission using stoichiometric models Ecology (IF 4.8) Pub Date : 2023-09-27 Dedmer B. Van de Waal, Lauren A. White, Rebecca Everett, Lale Asik, Elizabeth T. Borer, Thijs Frenken, Angélica L. González, Rachel Paseka, Eric W. Seabloom, Alexander T. Strauss, Angela Peace
Hosts rely on the availability of nutrients for growth, and for defense against pathogens. At the same time, changes in host nutrition can alter the dynamics of pathogens that rely on their host for reproduction. For primary producer hosts, enhanced nutrient loads may increase host biomass or pathogen reproduction, promoting faster density-dependent pathogen transmission. However, the effect of elevated

Sunken trees in the deep sea link terrestrial and marine biodiversity Ecology (IF 4.8) Pub Date : 2023-09-15 Craig R. McClain, Corie M. Boolukos, S. River D. Bryant, Granger Hanks
Wood in the deep-sea serves as substantial food source in an otherwise barren environment, forming specialized, endemic, and diverse community assemblages. This biodiversity reliance on a terrestrial source creates a linkage by which anthropogenic impacts on land can alter the deep oceans. Knowledge of alpha- or beta-diversity of entire wood-fall communities, and wooden drivers of each would elucidate

Resistance and resilience to invasion is stronger in synchronous than compensatory communities Ecology (IF 4.8) Pub Date : 2023-09-06 Janette L. Davidson, Lauren G. Shoemaker
While community synchrony is a key framework for predicting ecological constancy, the interplay between community synchrony and ecological invasions remains unclear. Yet the degree of synchrony in a resident community may influence its resistance and resilience to the introduction of an invasive species. Here we used a generalizable mathematical framework, constructed with a modified Lotka-Volterra

Fungal pathogens increase community temporal stability through species asynchrony regardless of nutrient fertilization Ecology (IF 4.8) Pub Date : 2023-09-06 Yimin Zhao, Xiang Liu, Jianbin Wang, Yu Nie, Mengjiao Huang, Li Zhang, Yao Xiao, Zhenhua Zhang, Shurong Zhou
Natural enemies and their interaction with host nutrient availability influence plant population dynamics, community structure, and ecosystem functions. However, the nature in which these factors influence patterns of community stability, as well as the direct and indirect processes underlying that stability, remain unclear. Here, we investigated the separate and interactive roles of fungal/oomycete

Female treefrog preference for breeding sites matches offspring performance in the presence of two anuran competitors Ecology (IF 4.8) Pub Date : 2023-09-06 David A. Dimitrie, Michael F. Benard
Preference-performance theory predicts that females should select breeding sites that maximize offspring performance. Amphibians have been a model system for investigating habitat selection, yet most studies have focused on habitat selection in response to predators and conspecifics. We investigated female oviposition site selection and larval performance in eastern gray treefrogs (Hyla versicolor)

Resource co-limitation of community biomass but not structure of an alpine grassland Ecology (IF 4.8) Pub Date : 2023-09-06 Juntao Zhu, Ning Zong, Peili Shi, Yunlong He, Xian Yang, Yangjian Zhang, Lin Jiang
Anthropogenic environmental changes are influencing the structure and function of many ecological communities, but their underlying mechanisms are often poorly understood. We conducted a seven-year field experiment to explore the ecological consequences of nitrogen (N) and phosphorous (P) enrichment in a high-altitude Tibetan alpine grassland. We found that the enrichment of both N and P, but not either

Maximum stem diameter predicts liana population demography Ecology (IF 4.8) Pub Date : 2023-09-07 Stefan A. Schnitzer, David M. DeFilippis, Antonio Aguilar, Boris Bernal, Salomé Peréz, Abelino Valdés, Seberino Valdés, Fidedigna Bernal, Adrián Mendoza, Biancolini Castro, Maria Garcia-Leon
Determining population demographic rates is fundamental to understanding differences in species’ life-history strategies and their capacity to coexist. Calculating demographic rates, however, is challenging and requires long-term, large-scale censuses. Body size may serve as a simple predictor of demographic rate; can it act as a proxy for demographic rate when those data are unavailable? We tested

Shifts in competitive structures can drive variation in species' phenology Ecology (IF 4.8) Pub Date : 2023-09-06 Patricia Kaye T. Dumandan, Glenda M. Yenni, S. K. Morgan Ernest
For many species, a well documented response to anthropogenic climate change is a shift in various aspects of its life history, including its timing or phenology. Often, these phenological shifts are associated with changes in abiotic factors used as proxies for resource availability or other suitable conditions. Resource availability, however, can also be impacted by competition, but the impact of

Fruit and seed traits and vertebrate–fruit interactions of tree species occurring in Guyana, Suriname, and French Guiana Ecology (IF 4.8) Pub Date : 2023-09-06 Rens W. Vaessen, Klaske van Wijngaarden, Laura Boeschoten, Ronja Knippers, Livia Durazzo, Loes Verkuil, Marijke van Kuijk
Seed dispersal is widely considered an important mechanism for the conservation of plant diversity. In tropical regions, over 80% of woody plant species are dispersed by vertebrates, often through the consumption of fruits. Our understanding of what drives interactions between vertebrates and fruits is limited. Through a systematic literature search, we compiled a database of fruit and seed traits

The role of seasonal migration in spatial population synchrony Ecology (IF 4.8) Pub Date : 2023-08-26 Ellen C. Martin, Brage Bremset Hansen, Ivar Herfindal, Aline Magdalena Lee
Spatially synchronized population dynamics are common in nature, and understanding their drivers is key for predicting species persistence. A main driver of synchrony between populations of the same species is shared environmental conditions, which cause populations closer together in space to be more synchronized than populations further from one another. Most theoretical and empirical understanding

Warmer temperatures reduce the transmission of a virus in a gregarious forest insect Ecology (IF 4.8) Pub Date : 2023-08-26 Paul MacDonald, Judith H. Myers, Jenny S. Cory
Understanding how climate warming will influence species interactions is a key question in ecology and predicting changes in the prevalence of disease outbreaks is particularly challenging. Ectotherms are likely to be more influenced by climatic changes as temperature governs their growth, feeding, development, and behavior. We test the hypothesis that pathogen transmission and host mortality will

The existence and strength of higher order interactions is sensitive to environmental context Ecology (IF 4.8) Pub Date : 2023-08-25 Jeremy W. Fox
One strategy for understanding the dynamics of any complex system, such as a community of competing species, is to study the dynamics of parts of the system in isolation. Ecological communities can be decomposed into single species, and pairs of interacting species. This reductionist strategy assumes that whole-community dynamics are predictable and explainable from knowledge of the dynamics of single

Soil microbes mediate the effects of resource variability on plant invasion Ecology (IF 4.8) Pub Date : 2023-08-23 Xue Zhang, Mark van Kleunen, Chunling Chang, Yanjie Liu
A fundamental question in ecology is which species will prevail over others amid changes in both environmental mean conditions and their variability. Although the widely accepted fluctuating resource hypothesis predicts that increases in mean resource availability and variability therein will promote nonnative plant invasion, it remains unclear to what extent these effects might be mediated by soil

Fitness, behavioral, and energetic trade-offs of different migratory strategies in a partially migratory species Ecology (IF 4.8) Pub Date : 2023-08-03 Andrea Soriano-Redondo, Aldina M. A. Franco, Marta Acácio, Ana Payo-Payo, Bruno Herlander Martins, Francisco Moreira, Inês Catry
Alternative migratory strategies can coexist within animal populations and species. Anthropogenic impacts can shift the fitness balance between these strategies leading to changes in migratory behaviors. Yet some of the mechanisms that drive such changes remain poorly understood. Here we investigate the phenotypic differences, and the energetic, behavioral, and fitness trade-offs associated with four

Deep meadows: Deep-water seagrass habitats revealed Ecology (IF 4.8) Pub Date : 2023-07-31 Belinda C. Martin, Ana Giraldo-Ospina, Sahira Bell, Marion Cambridge, Matthew W. Fraser, Brooke Gibbons, Euan S. Harvey, Gary A. Kendrick, Tim Langlois, Claude Spencer, Renae K. Hovey
Seagrass meadows across the globe are under increasing pressure from human activities and climate change (Dunic et al., 2021; Waycott et al., 2009). A major challenge limiting effective seagrass conservation is the paucity of global seagrass distribution data. Global estimates of seagrass distribution range from 150,000 to 600,000 km2 (Green & Short, 2003), with the most recent estimate of 160,387 km2

Just a cat fight or something more sinister? Infanticide is rare among female leopards Ecology (IF 4.8) Pub Date : 2023-07-31 Nikki le Roex, Andrew Bartlet, Luke T. B. Hunter, Guy A. Balme
Infanticide—the killing of another's dependent young by a nonparent—is an extreme form of intrasexual competition that occurs across a wide range of animal taxa (Hausfater & Hrdy, 2008). Infanticide is typically committed by males of polygamous species, as it increases male reproductive opportunity by inducing female victims to reproduce again (Hrdy, 1979). Female infanticide is rarer and less understood

Host infection and disease-induced mortality modify species contributions to the environmental reservoir Ecology (IF 4.8) Pub Date : 2023-07-31 Nichole A. Laggan, Katy L. Parise, J. Paul White, Heather M. Kaarakka, Jennifer A. Redell, John E. DePue, William H. Scullon, Joseph Kath, Jeffrey T. Foster, A. Marm Kilpatrick, Kate E. Langwig, Joseph R. Hoyt
Environmental pathogen reservoirs exist for many globally important diseases and can fuel epidemics, influence pathogen evolution, and increase the threat of host extinction. Species composition can be an important factor that shapes reservoir dynamics and ultimately determines the outcome of a disease outbreak. However, disease-induced mortality can change species communities, indicating that species

Fire influences ant diversity by modifying vegetation structure in an Australian tropical savanna Ecology (IF 4.8) Pub Date : 2023-07-20 François Brassard, Magen J. Pettit, Brett P. Murphy, Alan N. Andersen
Fire is a dominant ecological force shaping many faunal communities globally. Fire affects fauna either directly, such as by killing individuals, or indirectly, such as by modifying vegetation structure. Vegetation structure itself also modulates fire frequency and intensity. As such, faunal responses to fire need to be seen through the lens of variable fire activity and vegetation structure. Here

Spatial habitat heterogeneity influences host–pathogen dynamics in a patchy population of Ranchman's tiger moth Ecology (IF 4.8) Pub Date : 2023-07-20 Adam Pepi, Vincent Pan, Patrick Grof-Tisza, Marcel Holyoak, Alexis Ballman, Aiyanna Laws-McNeil, Vinay Mase, Cameron Moseley, Richard Karban
Host–pathogen dynamics are influenced by many factors that vary locally, but models of disease rarely consider dynamics across spatially heterogeneous environments. In addition, theory predicts that dispersal will influence host–pathogen dynamics of populations that are linked, although this has not been examined empirically in natural systems. We examined the spatial dynamics of a patchy population

Zarnetske, Eric R. Sokol
The relationship between biodiversity and stability, or its inverse, temporal variability, is multidimensional and complex. Temporal variability in aggregate properties, like total biomass or abundance, is typically lower in communities with higher species diversity (i.e., the diversity–stability relationship [DSR]). At broader spatial extents, regional-scale aggregate variability is also lower with

Accounting for central place foraging constraints in habitat selection studies Ecology (IF 4.8) Pub Date : 2023-06-29 Simon Benhamou, Nicolas Courbin
Habitat selection studies contrast actual space use with the expected use under the null hypothesis of no selection (hereafter neutral use). Neutral use is most often equated to the relative frequencies with which environmental features occur. This generates a considerable bias when studying habitat selection by foragers that perform numerous trips back and forth to a central place (CP). Indeed, the

Take me for a ride: Herbivores can facilitate plant reinvasions Ecology (IF 4.8) Pub Date : 2023-06-27 Lauren L. Sullivan, Allison K. Shaw
Herbivores shape plant invasions through impacts on demography and dispersal, yet only demographic mechanisms are well understood. Although herbivores negatively impact demography by definition, they can affect dispersal either negatively (e.g., seed consumption), or positively (e.g., caching). Exploring the nuances of how herbivores influence spatial spread will improve the forecasting of plant movement

Seasonality of reproduction in an ever-wet lowland tropical forest in Amazonian Ecuador Ecology (IF 4.8) Pub Date : 2023-06-27 Nancy C. Garwood, Margaret R. Metz, Simon A. Queenborough, Viveca Persson, S. Joseph Wright, David F. R. P. Burslem, Milton Zambrano, Renato Valencia
Flowering and fruiting phenology have been infrequently studied in the ever-wet hyperdiverse lowland forests of northwestern equatorial Amazonía. These Neotropical forests are typically called aseasonal with reference to climate because they are ever-wet, and it is often assumed they are also aseasonal with respect to phenology.

Evolutionary history shapes grassland productivity through opposing effects on complementarity and selection Ecology (IF 4.8) Pub Date : 2023-06-21 Daniel J. Larkin, Mary-Claire Glasenhardt, Evelyn W. Williams, Nisa Karimi, Rebecca S. Barak, Emma Leavens, Andrew L. Hipp
Phylogenetic diversity (PD), the evolutionary history of the organisms comprising a community, is increasingly recognized as an important driver of ecosystem function. However, biodiversity–ecosystem function experiments have rarely included PD as an a priori treatment. Thus, PD's effects in existing experiments are often confounded by covarying differences in species richness and functional trait

Fitness and niche differences are both important in explaining responses of plant diversity to nutrient addition Ecology (IF 4.8) Pub Date : 2023-06-15 Petr Dostál
Plant species loss due to eutrophication is a common phenomenon in temperate perennial grasslands. It occurs in a nonrandom fashion and is usually explained by increased competitive size asymmetry between the co-occurring winner (tall species with optima in productive habitats) and loser species (small-statured plants typical for unproductive habitats). It remains unclear why nutrient addition decreases

Characterizing tree trait variance over spatiotemporal scales Ecology (IF 4.8) Pub Date : 2023-06-15 Maria Natalia Umaña, Catherine M. Hulshof
Beyond the study of the mean, functional ecology lacks a concise characterization of trait variance patterns across spatiotemporal scales. Traits are measured in different ways, using different metrics, and at different spatial (and rarely temporal) scales. This study expands on previous research by applying a ubiquitous and widely used empirical model—Taylor's Power Law—to functional trait variance

Eco-evolutionary contributions to community trait change in floating aquatic plants Ecology (IF 4.8) Pub Date : 2023-06-01 Mark Davidson Jewell, Graham Bell
An entire community of organisms may become modified when its environment changes. These modifications can happen through physiological processes (plasticity), evolutionary processes (adaptation) or shifts in species composition (sorting). The outcome of these three sources of change constitutes the community's phenotypic response, but how they combine to drive community trait dynamics is not currently

Biological modification of coastal pH depends on community composition and time Ecology (IF 4.8) Pub Date : 2023-06-01 Cascade J. B. Sorte, Kristy J. Kroeker, Luke P. Miller, Matthew E. S. Bracken
Biological processes play important roles in determining how global changes manifest at local scales. Primary producers can absorb increased CO2 via daytime photosynthesis, modifying pH in aquatic ecosystems. Yet producers and consumers also increase CO2 via respiration. It is unclear whether biological modification of pH differs across the year, and, if so, what biotic and abiotic drivers underlie

Nutrient and stoichiometric time series measurements of decomposing coarse detritus in freshwaters Ecology (IF 4.8) Pub Date : 2023-06-01 Caleb J. Robbins, Beth C. Norman, Halvor M. Halvorson, David W. P. Manning, Elliot Bastias, Cristiane Biasi, Allyn K. Dodd, Rebecca A. Eckert, Alice Gossiaux, Jérémy Jabiol, Andrew S. Mehring, Ada Pastor
Decomposition of coarse detritus (e.g., dead organic matter larger than ~1 mm such as leaf litter or animal carcasses) in freshwater ecosystems is well described in terms of mass loss, particularly as rates that compress mass loss into one number (e.g., a first-order decay coefficient, or breakdown rate, “k”); less described are temporal changes in the elemental composition of these materials during
