Running a queer- and trans-inclusive microbiology faculty search

JL Weissman, Callie R Chappell, Bruno Francesco Rodrigues de Oliveira, et al.

Published: 2024-03-02
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 microbiology have emphasized the importance of addressing barriers to the success and retention of queer and trans microbiologists to create a more inclusive, equitable, and just scientific establishment. Crucially, [...]

Pursuit and escape drive fine-scale movement variation during migration in a temperate alpine ungulate

Christian John, Tal Avgar, Karl Rittger, et al.

Published: 2024-03-02
Subjects: Life Sciences

Climate change reduces snowpack, advances snowmelt phenology, drives summer warming, alters growing season precipitation regimes, and consequently modifies vegetation phenology in mountain systems. Altitudinal migrants cope with seasonal variation in such conditions by moving between seasonal ranges at different elevations, but vertical movements may be complex and are often not unidirectional [...]

Are microbes colimited by multiple resources?

Noelle A Held, Michael Manhart

Published: 2024-03-02
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 [...]

Agency in the Evolutionary Transition to Multicellularity

Stuart A Newman, Mariana Benítez, Ramray Bhat, et al.

Published: 2024-03-02
Subjects: Life Sciences

This review discusses concepts of how agency, defined here as organism-initiated behavior (both species-characteristic and individually idiosyncratic), was aligned at the cellular and integrated in the multicellular levels during evolution. We consider agency in relation to the autonomy and purposiveness of cells and multicellular organisms. While the agency of cells in extant multicellular forms [...]

Behavioural plasticity shapes population ageing patterns

Marta Acácio, Kaija Gahm, Nili Anglister, et al.

Published: 2024-02-29
Subjects: Ecology and Evolutionary Biology, Life Sciences

Studying the mechanisms shaping age-related changes in behaviour (“behavioural ageing”) is important for understanding population dynamics in our changing world. Yet, studies that capture within-individual behavioural changes in wild populations of long-lived animals are still scarce. Here, we used a 15-year GPS-tracking dataset of a social obligate scavenger, the griffon vulture (Gyps fulvus), [...]

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)

Jeffrey Robert Wall

Published: 2024-02-29
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 (IPLC’s) . It is precisely because it is a global standard that no claim that KBA proposal meaningfully (non-randomly) [...]

Harnessing Large Language Models for Coding, Teaching, and Inclusion to Empower Research in Ecology and Evolution

Natalie Cooper, Adam T Clark, Nicolas Lecomte, et al.

Published: 2024-02-28
Subjects: Life Sciences

1. Large language models (LLMs) are a type of artificial intelligence (AI) that can perform various natural language processing tasks. The adoption of LLMs has become increasingly prominent in scientific writing and analyses because of the availability of free applications such as ChatGPT. This increased use of LLMs raises concerns about academic integrity, but also presents opportunities for the [...]

Biologging for the future: how biologgers can help solve fundamental questions, from individuals to ecosystems

Roxanne Beltran, A. Marm Kilpatrick, Simona Picardi, et al.

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 [...]

Satellite derived trait data slightly improves tropical forest biomass, NPP and GPP predictions

Christopher Doughty, Camille Gaillard, Patrick Burns, et al.

Published: 2024-02-25
Subjects: Biology, Forest Sciences, Life Sciences

Improving tropical forest biomass predictions can accurately value tropical forests for their ecosystem services and establish confidence in carbon trading schemes such as REDD+. Optical remote sensing estimates of tropical forest biomass have produced spatially contradictory results that differ from ground plot biomass data. Recently, the Global Ecosystem Dynamics Investigation (GEDI) lidar was [...]

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.

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, [...]

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

Sergio Da Silva

Published: 2024-02-22
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.
