Functional coherence among miRNA targets: a potential metric for assessing biological signal among target prediction methods in non-model species

Christopher Wheat, Rachel A. Steward, Yu Okamura, et al.

Published: 2023-11-30
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences

Although miRNA regulation of protein production is a likely target of adaptive evolution, high false-positive rates in the identification of mRNAs targeted by miRNAs in non-model species’ complicates interpretation of recent advances. Here we document the challenges and then outline steps for the community to address these challenges.

Nitrogen fixation rates increase with diazotroph richness in the global ocean

Dominic Eriksson, Nicolas Gruber, Fabio Benedetti, et al.

Published: 2023-11-30
Subjects: Life Sciences

Marine diazotrophs, a highly specialized group of marine prokaryotes, convert atmospheric nitrogen gas into bioavailable forms of nitrogen and are thus critical to maintain the fertility of the ocean. However, little is known about the link between global-scale diazotroph diversity and marine N2 fixation rates. Here, we address this question by integrating more than 22’000 DNA sequencing and [...]

HPA flexibility and FKBP5: promising physiological targets for conservation

Cédric Zimmer, Blanca Jimeno, Lynn Martin

Published: 2023-11-30
Subjects: Life Sciences

Hypothalamic-pituitary-adrenal axis (HPA) flexibility is an emerging concept recognizing that individuals that will cope best with stressors will probably be those using their hormones in the most adaptive way. The HPA flexibility concept considers glucocorticoids as molecules that convey information about the environment from the brain to the body so that the organismal phenotype comes to [...]

The Site/Group Extended Data format and tools

Julien Yann Dutheil, Diyar Hamidi, Basile Pajot

Published: 2023-11-30
Subjects: Life Sciences

Comparative sequence analysis permits unravelling the molecular processes underlying gene evolution. Many statistical methods generate candidate positions within genes, such as fast or slowly-evolving sites, coevolving groups or residues, sites undergoing positive selection or changes in evolutionary rates. Understanding the functional causes of these evolutionary patterns requires combining the [...]

Coevolution-induced stabilizing and destabilizing selection shapes species richness in clade co-diversification

Yichao Zeng, David H. Hembry

Published: 2023-11-30
Subjects: Life Sciences

Coevolution can occur as a result of species interactions. However, it remains poorly understood how coevolution shapes the accumulation of species richness over macroevolutionary timescales. Assuming speciation occurs in a metacommunity as a result of genetic differentiation across communities due to dispersal limitation, we examine the effects of coevolution-induced stabilizing and [...]

A comparison of predictive performance of joint species distribution models for presence-absence data

David Peter Wilkinson, Nick Golding, Gurutzeta Guillera-Arroita, et al.

Published: 2023-11-28
Subjects: Life Sciences

1. While there has been substantial literature on the evaluation of predictions from single species distribution models, the topic of prediction has only recently begun to be addressed for joint species distribution models (JSDMs). These studies have covered only limited aspects of prediction: limited selection of models being compared, limited number of evaluation metrics, and/or not comparing [...]

Bacterial stress in the gut environment might increase the fitness cost associated with antibiotic resistance mechanisms: on the way to biorestoration of susceptible populations

Fernando Baquero, Jeronimo Rodríguez-Beltrán, Teresa M Coque, et al.

Published: 2023-11-28
Subjects: Medicine and Health Sciences

The acquisition and expression of antibiotic resistance implies changes in bacterial cell physiology, imposing fitness costs. Many human opportunistic pathogenic bacteria, such as those causing urinary tract or bloodstream infections, colonize the gut. In this review, we will examine the various types of stress that these bacteria might suffer during their intestinal stay. These stresses, and [...]

Consideration for Connection between Concrete and Abstract of Living System

Y Nishida

Published: 2023-11-28
Subjects: Life Sciences

Living systems are established by the coordination of diverse systems in the environment, are responsive to change, and are stable over time. Many studies and ideas have been proposed on the mechanisms and general laws of living systems from the viewpoints of evolutionary biology, systems biology, and chaos theory. The mechanisms of evolution and coordination of living systems are also related to [...]

Vocal Dimorphism in Anna’s Hummingbirds

Sierra Ru-Yi Glassman, Adi Domer, Adi Domer

Published: 2023-11-28
Subjects: Animal Sciences, Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Integrative Biology, Life Sciences, Ornithology, Zoology

Whereas vocal sexual dimorphism is widespread amongst birds, it has been historically overlooked in non-passerines such as hummingbirds. By evaluating correlations among sex, behaviors, and vocalizations, the meaning and utility of intentional sound production may be inferred. Anna's Hummingbirds (Calypte anna) exhibit pronounced sexual dimorphism, with males being larger and having more vibrant [...]

The costs of extra-pair mating

Jørgen S. Søraker, Jamie Dunning

Published: 2023-11-28
Subjects: Life Sciences

Extra-pair behaviours, where individuals copulate outside of an established pair bond, resulting in extra-pair paternity (EPP) of offspring, have long intrigued behavioural ecologists. Of particular interest is why females of otherwise socially monogamous species engage in extra-pair behaviours. Although researchers recognise that the drivers of variation in EPP, both within-species and [...]

this version should be deleted it is duplicated with the ID 6292 which is the correct version. Please delete this entry. I don't know why you guys have created two entries and this one with a wrong file that reads for review only.

Signal space overlap in sympatric drongos (Aves: Dicruridae) and spatial segregation in a South Asian tropical rainforest

Sutirtha Lahiri, Bablu Sonowal

Published: 2023-11-28
Subjects: Life Sciences

A diverse array of animals use a multidimensional acoustic space as a primary source of communication, especially in habitats where other signals are limited. However, in complex habitats, species must contend with other co-occurring species to send their message in a backdrop of ambient noise. This is exacerbated in closely related species that occur in sympatry, and we do not know how species [...]

Honest Signalling Made Simple

Jacob Chisausky, Carl Bergstrom, Kevin Zollman, et al.

Published: 2023-11-24
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences

Honest communication is a common phenomenon in animal behaviour, and is frequently explained by appeal to the so-called handicap hypothesis by which signal costs deter dishonesty. However, the handicap models commonly used to explain honest signalling have has been subject to several lines of criticism in recent literature. This trend may have led researchers outside of the field of animal [...]
