The response of trophic interaction networks to multiple stressors in a marine latitudinal gradient of the Southern Hemisphere

Tomas Ignacio Marina, Leonardo A Saravia, Iara D Rodriguez, et al.

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 for biodiversity conservation. Understanding how these networks react to environmental and anthropogenic stressors, especially along geographical gradients, is of increasing interest. This review presents a pioneering analysis of stressor responses in marine food webs from [...]

Mind the lag: understanding delayed genetic erosion

Roberta Gargiulo, Katharina B. Budde, Myriam Heuertz

Published: 2024-02-23
Subjects: Life Sciences

The delay between environmental changes and the corresponding genetic responses within populations is a common but surprisingly overlooked phenomenon in ecology, evolutionary and conservation genetics. This time lag problem can lead to erroneous conservation assessments when solely relying on genetic data. We identify population size, life-history traits, reproductive strategies and the severity [...]

Sex-specific discrimination of familiar and unfamiliar mates in the Tokay gecko

Marie-Ornelia Verger, Maëlle Devillebichot, Eva Ringler, et al.

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, [...]

Layers of latency in social networks and their implications for comparative analyses

Delphine De Moor, Lauren J. N. Brent, Matthew Silk, et al.

Published: 2024-02-22
Subjects: Life Sciences

Animal social systems are remarkably diverse. Linking this diversity to its ecological and evolutionary drivers and consequences has been a major focus of biological research. Initial efforts have been done within groups, populations, and species. Equipped with this information, researchers are now turning to investigations of social structure that are comparative in nature. However, comparing [...]

Survival of the luckiest

Subjects: Life Sciences, Social and Behavioral Sciences

Opposite dynamics are behind natural selection and sexual selection. When considering natural and sexual selection separately, the fittest individuals survive. However, when these processes interact, luck often determines the survivor. As a result, chance has a greater impact on evolution.

Call for new unified criteria for registering species data on 2000 Natura network areas

Meritxell Genovart, Rob Salguero-Gomez, Fernando Colchero, et al.

Published: 2024-02-21
Subjects: Life Sciences

We advocate for new unified and realistic criteria for monitoring and reporting data on species from 2000 Natura areas that allows cross-border comparisons and conservation diagnosis.

The changing landscape of text mining - a review of approaches for ecology and evolution

Maxwell J Farrell, Nicolas Le Guillarme, Liam Brierley, et al.

Published: 2024-02-21
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 [...]

Environmental Stress, Bacterial Cell Differentiation, and Antimicrobial Resistance

Fernando Baquero, Ana Moreno-Blanco, Rosa del-Campo

Published: 2024-02-20
Subjects: Life Sciences

Environmental stress, either natural or anthropogenic, influences both the form and function of bacterial cells. The general stress adaptive response of bacteria alters the bacterial shape, resulting in functional changes, as the bacterial cell has associated “organules” and molecular interactions that are dependent on the cell’s topology. These changes in form and function are frequently linked [...]

Reporting guidelines for terrestrial respirometry: Building openness, transparency of metabolic and evaporative water loss data

Nicholas C. Wu, Lesley Ann Alton, Rafael P Bovo, et al.

Published: 2024-02-20
Subjects: Animal Experimentation and Research, Comparative and Evolutionary Physiology, Integrative Biology, Life Sciences

Respirometry is an important procedure for understanding whole-animal energy and water balance. Consequently, the growing number of studies using respirometry over the last decade warrants reliable reporting and data sharing for effective research synthesis and dissemination. We provide a checklist guideline on five key areas to facilitate the transparency and reproducibly of respirometry [...]

Tempo and mode of diapause evolution in butterflies

Sridhar Halali, Etka Yapar, Christopher Wheat, et al.

Published: 2024-02-20
Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences

Quantifying the tempo and mode via modern phylogenetic comparative methods can provide crucial insights into the role of selection and constraints in trait evolution. Here we elucidate the evolution of diapause, a complex and defining life-history trait that allows temporal escape from unfavorable conditions in many insects, including our model system, butterflies. Using a thorough literature [...]

Energetic costs of mounting an immune response in a coral reef damselfish (Pomacentrus amboinensis)

Marie Levet, Dominique G. Roche, Shaun S Killen, et al.

Published: 2024-02-20
Subjects: Life Sciences

While immune responses can be energetically costly, quantifying these costs is challenging. We tested the metabolic costs of immune activation in damselfish (Pomacentrus amboinensis Bleeker, 1868) following a mass-adjusted injection of lipopolysaccharide (LPS) endotoxin. Fish were divided into eight treatments: two controls (handling and saline injection) and six LPS groups with concentrations [...]

Theoretical research to extract, combine and generate concepts for understanding life phenomena

Y Nishida

Published: 2024-02-20
Subjects: Life Sciences

Living systems evolve through interactions with the environment, which are nonequilibrium processes that resist the law of increasing entropy in the environment and maintain their organization by exhausting an entropy inflow from the environment. Although several principles have been proposed to explain the nonequilibrium processes of living systems and the mechanism of entropy extraction, a [...]

Loring Pond Duckweed Abundance and Diversity Assessment Via By-Catch of Surface Skimming, and Suitability of Compost for Organic Gardens

Brianna Matchette

Published: 2024-02-19
Subjects: Life Sciences

Duckweed are tiny aquatic plants that are part of the Lemnaceae family including five genera: Lemna, Landoltia, Spirodela, Wolffia, and Wolfiella. Previous research has shown duckweed to have strong properties of phytoremediation of heavy metals and other pollutants (Ekperusi et al., 2019). Here we examine Loring Pond, an urban pond in Minneapolis, Minnesota, that is partially covered by [...]

Reduced plasticity and variance in physiological rates of ectotherm populations under climate change

Daniel W.A. Noble, Fonti Kar, Alex Bush, et al.

Published: 2024-02-17
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences

Climate change is expected to result in warmer and more variable thermal environments globally. Greater thermal variability is expected to result in strong selection pressures leading to genetic adaptation and/or the evolution of adaptive phenotypic plasticity. Such responses depend on genetic and phenotypic variability. However, most work has focused on changes in mean phenotypic responses to [...]

Why are trees hollow? Termites, microbes, and tree internal stem damage in a tropical savanna

Abbey R Yatsko, Baptiste Wijas, Jed Calvert, et al.

Published: 2024-02-16
Subjects: Life Sciences

1. Wood plays a vital role in the terrestrial carbon cycle, serving as a significant carbon store that is then released back to the atmosphere during decomposition. Decomposition has largely been studied in fallen and standing deadwood; however, decomposition can occur within living trees via hollowing by wood-feeding termites and microbial heart rot. Internal stem damage is difficult to measure, [...]
