The effect of experimental hybridization on cognition and brain anatomy: limited phenotypic variation and transgression in Poeciliidae

Catarina Vila Pouca, Hannah De Waele, Alexander Kotrschal

Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Life Sciences

Hybridization can promote phenotypic variation and often produces trait combinations distinct from the parental species. This increase in available variation can lead to the manifestation of functional novelty when new phenotypes bear adaptive value under the environmental conditions in which they occur. While the role of hybridization as a driver of variation and novelty in traits linked to [...]

Scaling up and down: movement ecology for microorganisms

Nathan I. Wisnoski, Jay T. Lennon

Published: 2022-06-19
Subjects: Ecology and Evolutionary Biology, Life Sciences, Microbiology

Movement is critical for the fitness of organisms, both large and small. It dictates how individuals acquire resources, evade predators, exchange genetic material, and respond to stressful environments. Movement also influences ecological and evolutionary dynamics at scales beyond the individual organism. However, the links between individual motility and the processes that generate and maintain [...]

The vocal apparatus of bats: an understudied tool to reconstruct the evolutionary history of echolocation?

Until recently, bat phylogeny separated megabats (laryngeally non-echolocators) and microbats (all laryngeal echolocators) into two distinct clades. This segregation was consistent with the assumption that laryngeal echolocation was acquired by a common ancestor and inherited by all microchiropterans. Thus, laryngeal echolocation was regarded to have evolved once. Recent advances in bat genome [...]

Micro-evolutionary response of spring migration timing in a wild seabird

Maria Moiron, Celine Teplitsky, Birgen Haest, et al.

Published: 2022-06-07
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences

Understanding the mechanisms by which populations can adapt to changing environmental conditions is crucial for predicting their viability. In the context of rapid climate change, phenological advance is a key adaptation for which evidence is accumulating across taxa. Among vertebrates, phenotypic plasticity is known to underlie most of this phenological change, while evidence for micro-evolution [...]

EvoPhylo: an R package for pre- and postprocessing of morphological data from relaxed clock Bayesian phylogenetics

1. Relaxed clock Bayesian evolutionary inference (BEI) enables the co-estimation of phylogenetic trees and evolutionary parameters associated with models of character and lineage evolution. Fast advances in new model developments over the past decade have boosted BEI as a major macroevolutionary analytical framework using morphological and/or molecular data across vastly different study systems.

Decline effects are rare in ecology: Comment

Recently, Costello and Fox (2022) tested, with a large dataset, the hypothesis of whether there is a widespread decline effect in the discipline of ecology. In other words, the magnitude of the reported ecological effect sizes declines over time (Leimu and Koricheva 2004). Contrary to early results from much smaller datasets (Jennions and Møller 2002, Barto and Rillig 2012), Costello and Fox [...]

The Evolution of Peace

While some species have affiliative and even cooperative interactions between individuals of different social groups, humans are alone in having durable, positive-sum, interdependent relationships across unrelated social groups. Our capacity to have harmonious relationships that cross group boundaries is an important aspect of our species’ success, allowing for the exchange of ideas, materials, [...]

Perturbations highlight importance of social history in parakeet rank dynamics

Annemarie van der Marel, Xavier Francis, Claire L. O'Connell, et al.

Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences

Dominance hierarchies can provide many benefits to individuals, such as access to resources or mates, depending on their ranks. In some species, rank can emerge as a product of the history of social interactions within a group. However, it can be difficult to determine whether social history is critical to rank in observation-based studies. Here, we investigated rank dynamics in three captive [...]

Temporal variability declines with increasing trophic levels and spatial scales in freshwater ecosystems

Tadeu Siqueira, Charles Hawkins, Julian Olden, et al.

Published: 2022-05-30
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology

The temporal variability of ecological properties tends to decrease with spatial scale and levels of biological organization, but how does it propagate across trophic levels? We compiled metacommunity time-series datasets spanning basal resources to top predators from 355 freshwater sites across three continents. Temporal variability in abundance decreased from producers to tertiary consumers [...]

Best practices for LGBTQ+ inclusion during ecological fieldwork: Considering safety, cis/heteronormativity, and structural barriers

Jaime Jo Coon, Nathan Alexander, Emmett M Smith, et al.

Published: 2022-05-30
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology

Lesbian, gay, bisexual, trans, queer, and other marginalized gender and sexual identities (LGBTQ+) face unique barriers to participation in applied ecology. Such barriers are particularly relevant during fieldwork, including physical and discriminatory risks, increased isolation, and non-inclusive infrastructure.To be more inclusive, fieldwork should address LGBTQ+ safety and survival needs.

Its time to manage mountain lions in Texas

L. Mark Elbroch, Patricia Harveson

Published: 2022-05-27
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology

Mountain lions, also called cougars, pumas and Florida panthers, are a wide-ranging, large felid in the western hemisphere. Every U.S. state in which there are breeding populations of mountain lions offer the species some level of protection, except Texas. Here, we summarize historical research on mountain lions in Texas, human perceptions about the species, and historical discussions within [...]

Evolution and impact of socially transferred materials

Since the dawn of life, transfers of metabolized material between individuals have led to great innovations of evolution. When metabolized material is transferred from one individual’s body to another (as with sperm, eggs, milk, symbionts), secondary manipulative molecules that induce a physiological response in the receiver are often transferred along with the primary cargo. The bioactive and [...]

The role of climate change and niche shifts in divergent range dynamics of a sister-species pair

Jeremy Thomas Summers, Dieter Lukas, Corina J Logan, et al.

Published: 2022-05-25
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences

Species ranges are set by limitations in factors including climate tolerances, habitat use, and dispersal abilities. Understanding the factors governing species range dynamics remains a challenge that is ever more important in our rapidly changing world. Species ranges can shift if environmental changes affect available habitat, or if the niche or habitat connectivity of a species changes. We [...]

One hand washes the other: cooperation and conflict in hygiene and immunity

Gregory Albery

Published: 2022-05-25
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences

In humans and wild animals, pathogens impose costs on both the individual and the social group as a whole. To minimise these costs, group-living species have evolved many hygienic and immune traits that benefit from cooperation between individuals, thereby subjecting them to the laws of social evolution. Such social contracts include reciprocal grooming, altruistic self-isolation, spiteful [...]

Observations and collections of organisms form the basis of our understanding of Earth’s biodiversity and are an indispensable resource for global change studies. Geographic information is key, serving as the link between organisms and the environments they reside in. However, the geographic information associated with these records is often inaccurate, thus limiting their efficacy for research. [...]
