Developmental environments do not affect thermal physiology in reptiles: An experimental test and meta-analysis

Rose Zhang, Kris Wild, Patrice Pottier, et al.

Published: 2023-01-18
Subjects: Evolution, Integrative Biology, Other Ecology and Evolutionary Biology

On a global scale, organisms face significant challenges due to climate change and anthropogenic disturbance. In many ectotherms, developmental and physiological processes are sensitive to changes in temperature and resources. Developmental plasticity in thermal physiology may provide adaptive advantages to environmental extremes if early environmental conditions are predictable of late-life [...]

Inferring the identifying features underlying association preferences in wild mixed species parrot groups

Vanessa Ferdinand, Elle Pattenden, Donald Brightsmith, et al.

Published: 2022-09-16
Subjects: Biology, Integrative Biology, Life Sciences

Many animals participate in mixed-species aggregations for a variety of reasons, leading to species specific differences in benefits and costs, resulting in a variety of community assemblage patterns and dynamics based on what information individuals use to make joining decisions. Current research tends to focus specifically on "species" as a defining factor affecting joining decisions. However, [...]

Behavioural ecology at the spatial-social interface

Quinn Webber, Gregory Albery, Damien R. Farine, et al.

Published: 2022-02-11
Subjects: Biology, Integrative Biology, Life Sciences

Spatial and social behaviour are fundamental aspects of an animal’s biology, and the social and spatial environments are indelibly linked through mutual causes and shared consequences. Behavioural variation at the “spatial-social interface”, which we define as the intersection of social and spatial aspects of individuals’ phenotypes and environments, has implications for ecological and [...]

Latitudinal but not elevational variation in blood glucose level is linked to life history across passerine birds

Macrophysiological research is vital to our understanding of mechanisms underpinning global life history variation and adaptation under diverse environments. Birds represent an important model taxon in this regard, yet our knowledge is limited to only a few physiological traits, mostly studied in temperate and Neotropical species. Here, we examined latitudinal and elevational variation in an [...]

Ecogeography of group size suggests differences in drivers of sociality among cooperatively breeding fairywrens

Allison E. Johnson, Joseph F. Welklin, Ian R. Hoppe, et al.

Cooperatively breeding species exhibit a range of social behaviors associated with different costs and benefits to group-living, often in association with different environmental conditions. For example, species in which collective-care of offspring reduces the cost of reproduction are more common in harsh environments (true cooperative breeding), while species that collectively defend resources [...]

Bothersome burrowers: tracking gopher (Thomomys bottae) time-averaging in a late-Holocene site in California

Maria Viteri, Elizabeth Hadly

Subjects: Biology, Integrative Biology, Life Sciences

Understanding the taphonomic biases affecting fossil deposits is necessary in order to extract their true ecological signals. In terrestrial sites, the mixing of fossil material by mammalian bioturbators can substantially increase time-averaging, obscuring or even erasing stratification. In particular, pocket gophers (Thomomys sp.) are known to burrow in Holocene sites and thereby complicate the [...]

Mitochondria as the powerhouses of sexual selection: testing mechanistic links between development, cellular respiration, and bird song

Ondi L. Crino, Steph Falk, Andrew Katsis, et al.

Published: 2021-12-04
Subjects: Biology, Integrative Biology, Life Sciences

Although the influence of developmental conditions on the expression of sexually selected traits is established, the physiological mechanisms that modulate such effects remain a matter of intense debate. Here, we test the role of the developmental environment in shaping adult mitochondrial function and link mitochondrial function to expression of a sexually selected trait in males (bird song). We [...]

The role of sexual isolation during rapid ecological divergence: evidence for a new dimension of isolation in Rhagoletis pomonella

Alycia Lackey, Alyssa Murray, Nadia Mirza, et al.

Published: 2021-11-16
Subjects: Biology, Integrative Biology, Life Sciences

The pace of divergence and likelihood of complete speciation may depend how and when different types of reproductive barriers evolve. After initial reproductive barriers evolve, questions remain about how subsequently evolving barriers may facilitate additional divergence and potential speciation. We tested for the presence of sexual isolation (reduced mating between populations due to divergent [...]

Functions for simulating data and designing studies of physiological flexibility in the acute glucocorticoid response to stressors.

Wild animals often experience unpredictable challenges that demand rapid and flexible responses. The glucocorticoid mediated stress response is one of the major systems that allows vertebrates to rapidly adjust their physiology and behavior. Given its role in responding to challenges, evolutionary physiologists have focused on the consequences of between-individual and, more recently, [...]

Unreciprocated allogrooming hierarchies in a population of wild group-living mammals

Catherine E Nadin, David W. Macdonald, Sandra Baker, et al.

Published: 2021-08-06
Subjects: Biology, Integrative Biology, Life Sciences

Allogrooming can relate to social status in mammalian societies, and thus, be used to infer social structure. This relationship has previously been investigated by examining an individual’s dominance rank and their total amount of allogrooming. This, however, does not account for the identity of allogrooming partners. We applied a novel approach, calculating the linearity and steepness of [...]

Camera traps provide a virtual window into the natural world of wild animals, as they provide a noninvasive way to capture anatomical and behavioral information. Regular monitoring of wild populations through the collection of behavioral and demographic data is critical for the conservation of endangered species like the Asian elephant (Elephas maximus). Identifying individual elephants can [...]

Quantifying the dynamics of nearly 100 years of dominance hierarchy research

Elizabeth A. Hobson

Published: 2021-07-19
Subjects: Biology, Integrative Biology, Life Sciences

Dominance hierarchies have been studied for almost 100 years. A science of science approach can help provide high-level insight into how the dynamics of dominance hierarchy research have shifted or been maintained over this long timescale. To summarize these general patterns, I extracted publication metadata using a Google Scholar search of "dominance hierarchy, resulting in over 26,000 [...]

The ecology of wealth inequality in animal societies

Eli Strauss, Daizaburo Shizuka

Published: 2021-07-14
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Evolution, Integrative Biology, Life Sciences

Individuals vary in their access to resources, social connections, and phenotypic traits, and a central goal of evolutionary biology is to understand how this variation arises and influences fitness. Parallel research on humans has focused on the causes and consequences of variation in material possessions, opportunity, and health. Central to both fields of study is that unequal distribution of [...]

Explaining preemptive acclimation by linking information to plant phenotype

Pedro José Aphalo, Víctor O. Sadras

Published: 2021-07-07
Subjects: Agriculture, Biology, Ecology and Evolutionary Biology, Integrative Biology, Life Sciences

We review mechanisms for preemptive acclimation in plants and propose a conceptual model linking developmental and evolutionary ecology with the acquisition of information through sensing of cues and signals. The idea is that plants acquire much of the information in the environment not from individual cues and signals but instead from their joint multivariate properties such as correlations. If [...]

The dynamics of dominance: open questions, challenges, and solutions

Eli Strauss, Daizaburo Shizuka

Published: 2021-07-01
Subjects: Biology, Integrative Biology, Life Sciences

Although social hierarchies are recognized as dynamic systems, they are typically treated as static entities for practical reasons. Here, we ask what we can learn from a dynamical view of dominance, and provide a research agenda for the next decades. We identify five broad questions at the individual, dyadic, and group levels, exploring the causes and consequences of individual changes in rank, [...]
