Temperature drives the evolutionary diversification of male harm in Drosophila melanogaster flies
Published: 2024-03-12
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution
Sexual selection often leads to sexual conflict via pre-copulatory (harassment) and/or copulatory (traumatic insemination) male harm to females, impacting population growth, adaptation and evolutionary rescue. Male harm mechanisms are diverse and taxonomically widespread, but we largely ignore what ecological factors modulate their diversification. Here, we conducted experimental evolution under [...]
Community-wide masting improves predator satiation in North American oaks
Published: 2024-03-12
Subjects: Ecology and Evolutionary Biology, Life Sciences
Mast seeding, a phenomenon observed in numerous perennial plant species, is highly variable reproduction across years, synchronized among individuals within a population. One major fitness advantage of masting lies in the reduction of seed predation rates, achieved through alternating phases of seed scarcity and abundance that starve and subsequently satiate seed consumers. Proximately, the [...]
Running a queer- and trans-inclusive faculty hiring process
Published: 2024-03-03
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Microbiology
Queer and transgender scientists face documented systemic challenges across the sciences, and as a result have a higher attrition rate than their peers. Recent calls for change within science have emphasized the importance of addressing barriers to the success and retention of queer and trans scientists to create a more inclusive, equitable, and just scientific establishment. Crucially, we note [...]
Are microbes colimited by multiple resources?
Published: 2024-03-03
Subjects: Ecology and Evolutionary Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Life Sciences, Microbiology, Systems Biology
Resource colimitation --- the dependence of growth on multiple resources simultaneously --- has become an important topic in microbiology due both to the development of systems approaches to cell physiology and ecology, and to the relevance of colimitation to environmental science, biotechnology, and human health. Empirical tests of colimitation in microbes suggest that it may be common in [...]
Behavioral plasticity shapes population aging patterns in a long-lived avian scavenger
Published: 2024-03-01
Subjects: Ecology and Evolutionary Biology, Life Sciences
Studying the mechanisms shaping age-related changes in behavior (“behavioral aging”) is important for understanding population dynamics in our changing world. Yet, studies that capture within-individual behavioral changes in wild populations of long-lived animals are still scarce. Here, we used a 15-y GPS-tracking dataset of a social obligate scavenger, the griffon vulture (Gyps fulvus), to [...]
Evaluating Compatibility between the Key Biodiversity Area Proposal Process and Indigenous Peoples and Local Communities Environmental Priorities with evidence from Canada and Mi'kma'ki (Nova Scotia)
Published: 2024-03-01
Subjects: Ecology and Evolutionary Biology, Life Sciences, Public Affairs, Public Policy and Public Administration, Social and Behavioral Sciences
This report will demonstrate that no meaningful (non-random) compatibility exists between the Key Biodiversity Area proposal process – as it now exists and is being implemented globally and in Canada – and the biocultural priorities of Indigenous Peoples and Local Communities (IP&LC’s)*. It is precisely because it is a global standard that no claim that KBA proposal meaningfully (non-randomly) [...]
Minimum reporting standards can promote animal welfare and data quality in biologging research
Published: 2024-02-29
Subjects: Ecology and Evolutionary Biology
Biologging best practices have been carefully considered since the field’s inception six decades ago. The biologging research community has reduced instrument impacts on study animals by miniaturizing devices, employing sophisticated release mechanisms, and developing novel technological advancements. However, the field still needs standardized best practices for balancing data quality and animal [...]
Quantifying taxon-specific habitat connectivity requirements of urban wildlife using structured expert judgement
Published: 2024-02-28
Subjects: Biodiversity, Ecology and Evolutionary Biology, Research Methods in Life Sciences
Urban planning which enhances native biodiversity in and around cities is needed to address the impacts of urbanisation and conserve urban biodiversity. The “Biodiversity Sensitive Urban Design” (BSUD) framework incorporates ecological knowledge into urban planning to achieve positive biodiversity outcomes through improved urban design and infrastructure development. BSUD includes principles to [...]
Biologging for the future: how biologgers can help solve fundamental questions, from individuals to ecosystems
Published: 2024-02-25
Subjects: Ecology and Evolutionary Biology, Life Sciences
Archival instruments attached to animals (biologgers) have enabled exciting discoveries and have promoted effective conservation and management for decades. Recent research indicates that the field of biologging is poised to shift from pattern description to process explanation. Here we describe how biologgers have been - and can be - used to test hypotheses and challenge theory in behavior and [...]
The response of trophic interaction networks to multiple stressors along a large-scale latitudinal range in the Southern Hemisphere
Published: 2024-02-24
Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology
Ecological networks offer valuable insights into community structure, key species identification, and ecosystem management. Understanding how these networks respond to global change stressors is of increasing interest, especially along geographical gradients. This review summarizes potential stressor responses in marine food webs from the Southwest Atlantic to the Antarctic (45 - 78°S), [...]
Sex-specific discrimination of familiar and unfamiliar mates in the Tokay gecko
Published: 2024-02-23
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Social animals need to keep track of other individuals in their group to be able to adjust their behaviour accordingly and facilitate group cohesion. This recognition ability varies across species and is influenced by cognitive capacities such as learning and memory. In reptiles, particularly Squamates (lizards, snakes, and worm lizards), pheromonal communication is pivotal for territoriality, [...]
The changing landscape of text mining - a review of approaches for ecology and evolution
Published: 2024-02-20
Subjects: Ecology and Evolutionary Biology, Life Sciences
In ecology and evolutionary biology, synthesis and modelling of data from published literature is a common practice for generating insight and testing theories across systems. However, the tasks of searching, screening, and extracting data from literature are often arduous. Researchers may manually process hundreds to thousands of articles for systematic reviews, meta-analyses, and compiling [...]
Tempo and mode of diapause evolution in butterflies
Published: 2024-02-19
Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences
Quantifying the tempo and mode via modern phylogenetic comparative methods can provide insights into how selection and constraints shape trait evolution. Here we elucidate the evolution of diapause, a complex and key trait that allows temporal escape from unfavorable conditions in many insects, including our model system, butterflies. Using a thorough literature survey, we first scored the [...]
Limited plasticity but increased variance in physiological rates across ectotherm populations under climate change
Published: 2024-02-17
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences
Climate change causes warmer and more variable temperatures globally, impacting physiological rates and function in ectothermic animals. Acclimation of physiological rates can help maintain function. However, it is unresolved how variance in physiological rates changes with temperature despite its potential ecological and evolutionary importance. We tested whether thermal variation affects [...]
Assessing the risk of climate maladaptation for Canadian polar bears
Published: 2024-02-10
Subjects: Ecology and Evolutionary Biology, Life Sciences
Abstract The Arctic is warming four times faster than the rest of the world, threatening the persistence of Arctic species. It is uncertain if Arctic wildlife will have sufficient time to adapt to such rapidly warming environments. We used genetic forecasting to measure the risk of maladaptation to warming temperatures and sea ice loss in polar bears (Ursus maritimus) sampled across the Canadian [...]
