High temperatures reduce growth, infection, and transmission of a naturally occurring fungal plant pathogen Ecology (IF 4.4) Pub Date : 2024-06-26 Dalia V. Chen, Samuel P. Slowinski, Allyson K. Kido, Emily L. Bruns
Climate change is rapidly altering the distribution of suitable habitats for many species as well as their pathogenic microbes. For many pathogens, including vector‐borne diseases of humans and agricultural pathogens, climate change is expected to increase transmission and lead to pathogen range expansions. However, if pathogens have a lower heat tolerance than their host, increased warming could generate

Decadal‐scale time series highlight the role of chronic disturbances in driving ecosystem collapse in the Anthropocene Ecology (IF 4.4) Pub Date : 2024-06-20 Peter J. Edmunds
Biome degradation characterizes the Anthropocene Epoch, and modern ecology is deeply involved with describing the changes underway. Most research has focused on the role of acute disturbances in causing conspicuous changes in ecosystem structure, which leads to an underappreciation of the chronic effects causing large changes through the cumulative effects of small perturbations over decades.

Forest harvest causes rapid changes of maternal investment strategies in ground beetles Ecology (IF 4.4) Pub Date : 2024-05-28 Lauren Egli, Timothy T. Work
Species recovery following anthropogenic disturbances will depend on adaptations in survivorship and fecundity. Life‐history theory predicts increased environmental stress will result in (1) shifts in resource allocation from fecundity to body growth/maintenance and (2) increased provisioning among offspring at the cost of reproductive output. For remnant populations that persist after forest harvesting

Juvenile survival increases with dispersal distance and varies across years: 15 years of evidence in a prairie perennial Ecology (IF 4.4) Pub Date : 2024-05-28 Lea K. Richardson, Scott W. Nordstrom, Amy Waananen, Riley D. Thoen, Amy B. Dykstra, Gretel Kiefer, Drake E. Mullett, Erin G. Eichenberger, Ruth G. Shaw, Stuart Wagenius
Juvenile survival is critical to population persistence and evolutionary change. However, the survival of juvenile plants from emergence to reproductive maturity is rarely quantified. This is especially true for long‐lived perennials with extended pre‐reproductive periods. Furthermore, studies rarely have the replication necessary to account for variation among populations and cohorts. We estimated

Extending trait dispersion across trophic levels: Predator assemblages act as top‐down filters on prey communities Ecology (IF 4.4) Pub Date : 2024-05-20 Collin P. Gross, John J. Stachowicz
Studies of community assembly typically focus on the effects of abiotic environmental filters and stabilizing competition on functional trait dispersion within single trophic levels. Predation is a well‐known driver of community diversity and composition, yet the role of functionally diverse predator communities in filtering prey community traits has received less attention. We examined functionally

Growth of brown trout in the wild predicted by embryo stress reaction in the laboratory Ecology (IF 4.4) Pub Date : 2024-05-16 Jonas Bylemans, Lucas Marques da Cunha, Laetitia G. E. Wilkins, David Nusbaumer, Anshu Uppal, Claus Wedekind
Laboratory studies on embryos of salmonids, such as the brown trout (Salmo trutta), have been extensively used to study environmental stress and how responses vary within and between natural populations. These studies are based on the implicit assumption that early life‐history traits are relevant for stress tolerance in the wild. Here we test this assumption by combining two data sets from studies

Spawning fish maintains trophic synchrony across time and space beyond thermal drivers Ecology (IF 4.4) Pub Date : 2024-05-15 Anders Frugård Opdal, Peter J. Wright, Geir Blom, Hannes Höffle, Christian Lindemann, Olav Sigurd Kjesbu
Increasing ocean temperature will speed up physiological rates of ectotherms. In fish, this is suggested to cause earlier spawning due to faster oocyte growth rates. Over time, this could cause spawning time to become decoupled from the timing of offspring food resources, a phenomenon referred to as trophic asynchrony. We used biological data, including body length, age, and gonad developmental stages

Developmental stage‐dependent effects of perceived predation risk on nestling tree swallows (Tachycineta bicolor) Ecology (IF 4.4) Pub Date : 2024-05-09 Sabrina M. McNew, Conor C. Taff, Cedric Zimmer, Jennifer J. Uehling, Thomas A. Ryan, David Chang van Oordt, Jennifer L. Houtz, Allison S. Injaian, Maren N. Vitousek
The risk of predation directly affects the physiology, behavior, and fitness of wild birds. Strong social connections with conspecifics could help individuals recover from a stressful experience such as a predation event; however, competitive interactions also have the potential to exacerbate stress. Few studies have investigated the interaction between environmental stressors and the social landscape

Species traits may determine plant interactions along with soil microbiome, further shaping plant–soil feedbacks (PSFs). However, how plant traits modulate PSFs and, consequently, the dominance of plant functional groups remains unclear. We used a combination of field surveys and a two‐phase PSF experiment to investigate whether forbs and graminoids differed in PSFs and in their trait–PSF associations

Environmental warming increases the importance of high‐turnover energy channels in stream food webs Ecology (IF 4.4) Pub Date : 2024-05-07 James R. Junker, Wyatt F. Cross, James M. Hood, Jonathan P. Benstead, Alexander D. Huryn, Daniel Nelson, Jón S. Ólafsson, Gísli M. Gíslason
Warming temperatures are altering communities and trophic networks across Earth's ecosystems. While the overall influence of warming on food webs is often context‐dependent, increasing temperatures are predicted to change communities in two fundamental ways: (1) by reducing average body size and (2) by increasing individual metabolic rates. These warming‐induced changes have the potential to influence

Increased temperatures associated with urbanization (the “urban heat island” effect) have been shown to impact a wide range of traits across diverse taxa. At the same time, climatic conditions vary at fine spatial scales within habitats due to factors including shade from shrubs, trees, and built structures. Patches of shade may function as microclimate refugia that allow species to occur in habitats

Ecology of fear alters behavior of grizzly bears exposed to bear‐viewing ecotourism Ecology (IF 4.4) Pub Date : 2024-04-30 Monica L. Short, Christina N. Service, Justin P. Suraci, Kyle A. Artelle, Kate A. Field, Chris T. Darimont
Humans are perceived as predators by many species and may generate landscapes of fear, influencing spatiotemporal activity of wildlife. Additionally, wildlife might seek out human activity when faced with predation risks (human shield hypothesis). We used the anthropause, a decrease in human activity resulting from the COVID‐19 pandemic, to test ecology of fear and human shield hypotheses and quantify

Effects of predation risk on parasite–host interactions and wildlife diseases Ecology (IF 4.4) Pub Date : 2024-04-29 David W. Thieltges, Pieter T. J. Johnson, Anieke van Leeuwen, Janet Koprivnikar
Landscapes of fear can determine the dynamics of entire ecosystems. In response to perceived predation risk, prey can show physiological, behavioral, or morphological trait changes to avoid predation. This in turn can indirectly affect other species by modifying species interactions (e.g., altered feeding), with knock‐on effects, such as trophic cascades, on the wider ecosystem. While such indirect

Synchrony in adult survival is remarkably strong among common temperate songbirds across France Ecology (IF 4.4) Pub Date : 2024-04-29 Manon Ghislain, Timothée Bonnet, Ugoline Godeau, Olivier Dehorter, Olivier Gimenez, Pierre‐Yves Henry
Synchronous variation in demographic parameters across species increases the risk of simultaneous local extinction, which lowers the probability of subsequent recolonization. Synchrony therefore tends to destabilize meta‐populations and meta‐communities. Quantifying interspecific synchrony in demographic parameters, like abundance, survival, or reproduction, is thus a way to indirectly assess the stability

Donnelly, Somphot Duangchantrasiri, Gabriella Fredriksson, Benoit Goossens, Alys Granados, Andrew Hearn, Jason Hon, Tom Hughes, Patrick Jansen, Kae Kawanishi, Margaret Kinnaird
Information on tropical Asian vertebrates has traditionally been sparse, particularly when it comes to cryptic species inhabiting the dense forests of the region. Vertebrate populations are declining globally due to land‐use change and hunting, the latter frequently referred as “defaunation.” This is especially true in tropical Asia where there is extensive land‐use change and high human densities

The complex circuitry of interactions determining coexistence among plants and mycorrhizal fungi Ecology (IF 4.4) Pub Date : 2024-03-20 Mark A. McPeek, Caitlin Hicks Pries
We present a mechanistic model of coexistence among a mycorrhizal fungus and one or two plant species that compete for a single nutrient. Plant–fungal coexistence is more likely if the fungus is better at extracting the environmental nutrient than the plant and the fungus acquires carbon from the plant above a minimum rate. When they coexist, their interaction can shift from mutualistic to parasitic

Evolution of avian heat tolerance: The role of atmospheric humidity Ecology (IF 4.4) Pub Date : 2024-03-19 Marc T. Freeman, Bianca Coulson, James C. Short, Celiwe A. Ngcamphalala, Mathome O. Makola, Andrew E. McKechnie
The role of atmospheric humidity in the evolution of endotherms' thermoregulatory performance remains largely unexplored, despite the fact that elevated humidity is known to impede evaporative cooling capacity. Using a phylogenetically informed comparative framework, we tested the hypothesis that pronounced hyperthermia tolerance among birds occupying humid lowlands evolved to reduce the impact of
