Detection of energetic equivalence depends on food web architecture and estimators of energy use
Published: 2024-07-04
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology
Ecologists have long debated the universality of the energetic equivalence rule (EER), which posits that population energy use should be invariant with average body size due to negative size–density scaling. We explored size–density and size–energy use scaling across 183 geographically–distributed soil invertebrate food webs to investigate the universality of these fundamental EER assumptions. [...]
Topoclimate buffers floristic diversity from macroclimate in temperate mountain forests.
Published: 2024-07-04
Subjects: Biodiversity, Ecology and Evolutionary Biology, Forest Sciences, Life Sciences, Other Ecology and Evolutionary Biology
Microclimates strongly influence the composition and diversity of forest plant communities. Recent studies have highlighted the role of tree canopies in shaping understory thermal conditions at small spatial scales, especially in lowland forests. In mountain forests, however, the influence of topography in environmental conditions (e.g. topoclimate) is ought to also influence plants’ perceived [...]
From eggs to adulthood: sustained effects of early developmental temperature and corticosterone exposure on physiology and body size in an Australian lizard
Published: 2024-06-28
Subjects: Biochemistry, Biophysics, and Structural Biology, Biology, Integrative Biology, Life Sciences, Other Ecology and Evolutionary Biology
As global temperatures continue to rise due to climate change, developing animals may be increasingly exposed to elevated temperatures. Developing vertebrates can be affected by elevated temperatures directly, and indirectly through maternal effects such as increased exposure to prenatal glucocorticoid hormones. Although many studies have examined how elevated temperatures and glucocorticoid [...]

Is the audience gender-blind? Smaller attendance in female talks highlights imbalanced visibility in academia
Published: 2024-05-27
Subjects: Ecology and Evolutionary Biology, Environmental Sciences, Evolution, Gender Equity in Education, Higher Education, Inequality and Stratification, Other Ecology and Evolutionary Biology, Psychological Phenomena and Processes
Although diverse perspectives are fundamental for fostering and advancing science, power relations have limited the development, propagation of ideas, and recognition of political minority groups in academia. Gender bias is one of the most well-documented processes, leading women to drop out of their academic careers due to fewer opportunities and lower recognition. Using long-term data [...]
Light Pollution at Sea: Implications and Potential Hazards of Human Activity for Offshore Bird and Bat Movements in the Greater North Sea
Published: 2024-05-24
Subjects: Environmental Health and Protection, Environmental Indicators and Impact Assessment, Environmental Studies, Life Sciences, Marine Biology, Natural Resources and Conservation, Natural Resources Management and Policy, Nature and Society Relations, Ornithology, Other Animal Sciences, Other Ecology and Evolutionary Biology, Social and Behavioral Sciences, Terrestrial and Aquatic Ecology, Water Resource Management, Zoology
Human activity in the North Sea is intensifying, as emerging uses, such as offshore wind farms (OWFs) and liquid natural gas (LNG) terminals, are added to fishing, freight shipping and fossil fuel production as traditional forms of resource exploitation. The volume and scale of these additional installations are projected to increase substantially in the coming decades, which amplifies the need [...]
Designing causal mediation analyses to quantify intermediary processes in ecology
Published: 2024-05-13
Subjects: Applied Statistics, Longitudinal Data Analysis and Time Series, Other Ecology and Evolutionary Biology, Statistical Methodology
Ecologists seek to understand the intermediary ecological processes through which changes in one attribute in a system affect other attributes. Yet, quantifying the causal effects of these mediating processes in ecological systems is challenging. We must define what we mean by a “mediated effect”, determine what assumptions are required to estimate mediation effects without bias, and assess [...]
Global review of shorebird tracking publications: Gaps and priorities for research and conservation
Published: 2024-05-07
Subjects: Animal Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Ornithology, Other Ecology and Evolutionary Biology, Research Methods in Life Sciences
Electronic tracking has enabled rapid advances in knowledge of the movement behaviour and habitat use of shorebirds (Charadriiformes), and is thus making a growing contribution to their conservation. However, developing a useful coherent global strategy for tracking these taxa requires an overview of the current availability of data and how it varies along regional and ecological lines. To this [...]
Guidance framework to apply best practices in ecological data analysis: Lessons learned from building Galaxy-Ecology
Published: 2024-04-11
Subjects: Bioinformatics, Other Ecology and Evolutionary Biology
Numerous conceptual frameworks exist for best practices in research data and analysis (e.g. Open Science and FAIR principles). In practice, there is a need for further progress to improve transparency, reproducibility, and confidence in ecology. Here, we propose a practical and operational framework for researchers and experts in ecology to achieve best practices for building analytical [...]
Effectiveness of toxic baiting for the control of canines and felines
Published: 2024-04-11
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Lethal, toxic baiting has been widely adopted for the control of canines and felines. However, high variability in findings make it difficult to gauge the overall efficacy of this control method across studies. We conducted a meta-analysis of the efficacy of lethal baiting for the feral cat, red fox and dingo; our outcome of interest was apparent predator survival. Our dataset contained 121 [...]
Cryptic species and hybridisation in corals: challenges and opportunities for conservation and restoration
Published: 2024-02-14
Subjects: Genomics, Marine Biology, Other Ecology and Evolutionary Biology
The conservation and management of coral reef ecosystems will benefit from accurate assessments of reef-building coral species diversity. However, the true diversity of corals may be obfuscated by cryptic yet genetically distinct groups, which are likely more pervasive than currently recognised. Here, we investigate the prevalence of cryptic coral groups and assess evidence for their permeability [...]
The Distraction Function of Extrafloral Nectaries: Keeping Ants Away From Flowers and Preventing Disruption of Pollination
Published: 2024-01-30
Subjects: Desert Ecology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
In exchange for extrafloral nectar, ants deter herbivores from the plants, reducing the amount of herbivory they suffered. However, this defensive mutualism can sometimes have negative effects on plants, as ants may also visit flowers, deterring pollinators and reducing plant fitness. The Distraction Hypothesis posits that extrafloral nectaries (EFNs) have the function of attracting ants and [...]
Multiple habitat graphs: how connectivity brings forth landscape ecological processes
Published: 2024-01-30
Subjects: Other Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology
Purpose: Habitat connectivity is integral to current biodiversity science and conservation strategies. Originally, the connectivity concept stressed the role of individual movements for landscape-scale processes. Connectivity determines whether populations can survive in sub-optimal patches (i.e., source-sink effects), complete life cycles relying on different habitat types (i.e., landscape [...]
The genetic basis of a regionally isolated sexual dimorphism involves cortex
Published: 2024-01-29
Subjects: Biology, Evolution, Genetics and Genomics, Other Ecology and Evolutionary Biology, Population Biology
Sexual dimorphisms represent a source of phenotypic variation and result from differences in how natural and sexual selection act on males and females within a species. Identifying the genetic basis of dimorphism can be challenging, especially once it is fixed within a species. However, studying polymorphisms, even when fixed within a population, can provide insights into the genetic basis of [...]
Predicting organismal response to marine heatwaves using mechanistic thermal landscape models
Published: 2024-01-23
Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Other Ecology and Evolutionary Biology
Marine heatwaves (MHWs) can cause thermal stress in marine ectotherms, experienced as a pulse against the press of anthropogenic warming. When thermal stress exceeds organismal capacity to maintain homeostasis, organism survival becomes time-limited and can result in mass mortality events. Current methods of detecting and categorizing MHWs rely on statistical analysis of historic climatology, and [...]
