  • Environmental forcing and predator consumption outweigh the nonconsumptive effects of multiple predators on oyster reefs
    Ecology (IF 4.285) Pub Date : 2020-04-02
    David L. Kimbro; Hanna G. Tillotson; J. Wilson White

    The ability to predict how predators structure ecosystems has been shown to depend on identifying both consumptive effects (CEs) and nonconsumptive effects (NCEs) of predators on prey fitness. Prey populations may also be affected by interactions between multiple predators across life stages of the prey and by environmental factors such as disturbance. However, the intersection of these multiple drivers

  • Omitted variable bias in studies of plant interactions.
    Ecology (IF 4.285) Pub Date : 2020-04-02
    Matthew J Rinella,Dustin J Strong,Lance T Vermeire

    Models of plant-plant interactions underpin our understanding of species coexistence, invasive plant impacts and plant community responses to climate change. In recent studies, models of competitive interactions failed predictive tests, thereby casting doubt on results of many past studies. We believe these model failures owe at least partly to heterogeneity in unmodelled factors (e.g. nutrients, soil

    Soil bacterial communities are pivotal in regulating terrestrial biogeochemical cycles and ecosystem functions. The increase in global nitrogen (N) deposition has impacted various aspects of terrestrial ecosystems, but we still have a rudimentary understanding of whether there is a threshold for N input level beyond which soil bacterial communities will experience critical transitions.

    Seed dispersal and local filtering interactively govern community membership and scale up to shape regional vegetation patterns, but data revealing how and why particular species are excluded from specific communities in nature are scarce. This lack of data is a missing link between our theoretical understanding of how diversity patterns can form and how they actually form in nature, and it hampers

    Analyses of heat tolerance in insects often suggest that this trait is relatively invariant, leading to the use of fixed thermal maxima in models predicting future distribution of species in a warming world. Seasonal environments expose populations to a wide annual temperature variation. To evaluate the simplifying assumption of invariant thermal maxima, we quantified heat tolerance of 26 ant species

    The movement of organisms across habitat boundaries has important consequences for populations, communities, and ecosystems. However, because most species are not well adapted to all habitat types, dispersal into suboptimal habitats could induce physiological changes associated with persistence strategies that influence community assembly.

    Function and abundances shape species interactions and thus ecological communities. While communities are often summarized as the mean function of each species, intraspecific variation in traits and thus function is an important driver of community composition. Ontogeny is a common source of intraspecific variation, but while age‐related functional changes can alter species interactions, so too can

    Long-term ecological research can resolve effects of disturbance on ecosystem dynamics by capturing the scale of disturbance and interactions with environmental changes. To quantify how disturbances interact with long-term directional changes (sea-level rise, freshwater restoration), we studied 17 years of monthly dissolved organic carbon (DOC), total nitrogen (TN) and phosphorus (TP) concentrations

  • Finding missing links in interaction networks
    Ecology (IF 4.285) Pub Date : 2020-03-27

    Documenting which species interact within ecological communities is challenging and labour‐intensive. As a result, many interactions remain unrecorded, potentially distorting our understanding of network structure and dynamics. We test the utility of four structural models and a new coverage‐deficit model for predicting missing links in both simulated and empirical bipartite networks. We find they

  • Counting niches: Abundance-by-trait patterns reveal niche partitioning in a Neotropical forest.
    Ecology (IF 4.285) Pub Date : 2020-02-20
    Rafael D'Andrea,John Guittar,James P O'Dwyer,Hector Figueroa,S J Wright,Richard Condit,Annette Ostling

    Tropical forests challenge us to understand biodiversity, as numerous seemingly similar species persist on only a handful of shared resources. Recent ecological theory posits that biodiversity is sustained by a combination of species differences reducing interspecific competition and species similarities increasing time to competitive exclusion. Together, these mechanisms counterintuitively predict

  • Climate warming and heat waves alter harmful cyanobacterial blooms along the benthic-pelagic interface.
    Ecology (IF 4.285) Pub Date : 2020-02-21
    Pablo Urrutia-Cordero,Huan Zhang,Fernando Chaguaceda,Hong Geng,Lars-Anders Hansson

    In addition to a rise in mean air and water temperatures, more frequent and intense extreme climate events (such as heat waves) have been recorded around the globe during the past decades. These environmental changes are projected to further intensify in the future, and we still know little on how they will affect ecological processes driving harmful cyanobacterial bloom formation. Therefore, we conducted

  • Community efficiency during succession: a test of MacArthur's minimization principle in phytoplankton communities.
    Ecology (IF 4.285) Pub Date : 2020-02-18
    Giulia Ghedini,Michel Loreau,Dustin J Marshall

    Robert MacArthur's niche theory makes explicit predictions on how community function should change over time in a competitive community. A key prediction is that succession progressively minimizes the energy wasted by a community, but this minimization is a trade-off between energy losses from unutilised resources and costs of maintenance. By predicting how competition determines community efficiency

  • Temporal variation in effect sizes in a long-term, split-plot field experiment.
    Ecology (IF 4.285) Pub Date : 2020-02-07
    Alexandro B Leverkus,Michael J Crawley

    Ecological field experiments initiate successional and evolutionary changes amongst resident species, yet effect sizes are often reported as if they were constants. Few ecological studies have addressed their questions through long-term, experimental approaches, and many questions remain unanswered regarding temporal patterns in ecological effect sizes. We document temporal variation in effect sizes

  • Interactions of nitrogen and phosphorus cycling promote P acquisition and explain synergistic plant growth responses.

    Per Marten Schleuss,Meike Widdig,Anna Heintz-Buschart,Kevin Kirkman,Marie Spohn

    Plant growth is often co-limited by nitrogen (N) and phosphorus (P). Plants might use one element to acquire another (i.e. trading N for P and P for N), which potentially explains synergistic growth responses to NP addition. We studied a 66-year-old grassland experiment in South Africa that consists of four levels of N addition with and without P addition. We investigated the response of aboveground

    Johannes Heinze,Alexander Wacker,Andrew Kulmatiski

    Relatively little is known about how plant soil feedbacks (PSFs) may affect plant growth in field conditions where factors such as herbivory may be important. Using a potted experiment in a grassland, we measured PSFs with and without aboveground insect herbivory for 20 plant species. We then compared PSF values to plant landscape abundance. Aboveground herbivory had a large negative effect on PSF

    The Colombian Tropical Andes are one of the regions with highest bird diversity on Earth. However, information on bird morphology, reproductive phenology, and molt is particularly scarce in this region. Also, this region is heavily impacted by deforestation, and it is vulnerable to climate change. Hence, providing baseline information on life history and morphological traits will be essential to support

    Lianas, woody climbing plants, are increasing in many tropical forests, with cascading effects such as decreased forest productivity, carbon sequestration, and resilience. Possible causes are increasing forest fragmentation, CO2 fertilization, and drought. Determining the primary changing species and their underlying vital rates help explain the liana trends. We monitored over 17,000 liana stems for

  • Invasive species interact with climatic variability to reduce success of natives.

    Marina L LaForgia,Susan P Harrison,Andrew M Latimer

    Plants have evolved resource-conservative and resource-acquisitive strategies to deal with variability in rainfall, but interactions with dominant invasive species may undermine these adaptations. To investigate the relative effect of invaders on species with these two strategies, we manipulated rainfall and invasive grass presence and measured demographic rates in three resource-acquisitive and three

    Why some species become invasive while others do not remains an elusive question. It has been proposed that invasive species should depend less on mutualisms, because their spread would then be less constrained by the availability of mutualistic partners. We tested this idea with the genus Pinus, whose degree of invasiveness is known at the species level (being highly and negatively correlated with

    We took advantage of two natural experiments to investigate processes that regulate tree recruitment in gaps. In the first, we examined the recruitment of small and large saplings and trees into 31 gaps resulting from treefalls occurring between 1984 and 2015 in the 2.25 ha core area of a 4 ha tree plot at Cocha Cashu in Perú. In the second, we identified the tallest saplings recruiting into 69 gaps
