Widespread disruptive selection in the wild is associated with intense resource competition
BMC Evolutionary Biology, 2012 Background Disruptive selection has been documented in a growing number of natural populations. Yet, its prevalence within individual systems remains unclear. Furthermore, few studies have sought to identify the ecological factors that promote disruptive

Insecticide-mediated shift in ecological dominance between two competing species of grain beetles.
PLoS ONE, 2014 Competition is a driving force regulating communities often considered an intermittent phenomenon, difficult to verify and potentially driven by environmental disturbances.

GRAY WOLF POPULATION PROJECTION WITH INTRASPECIFIC COMPETITION
Natural Resource Modeling, 2014 AbstractCompetition effects are incorporated into a model of wolf‐population dynamics. A classic single‐state model is augmented into a dual‐state mapping of the evolution of the size of wolf packs and the number of wolf packs. This dual‐state model, unlike the single‐state density dependent model, is amenable to analyzing intraspecific competition ...

Anthropogenic change decouples a freshwater predator’s density feedback
Scientific Reports, 2023 Intraspecific interactions within predator populations can affect predator–prey dynamics and community structure, highlighting the need to better understand how these interactions respond to anthropogenic change. To this end, we used a half-century (1969–

The Anatomical Record, EarlyView.Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

Ecology Letters, 2018 Abstract Theory predicts that intraspecific competition should be stronger than interspecific competition for any pair of stably coexisting species, yet previous literature reviews found little support for this pattern. We screened over 5400 publications and identified 39 studies that quantified phenomenological intraspecific and ...

Predators weaken prey intraspecific competition through phenotypic selection
Ecology Letters, 2020 Abstract Predators have a key role shaping competitor dynamics in food webs. Perhaps the most obvious way this occurs is when predators reduce competitor densities. However, consumption could also generate phenotypic selection on prey that determines the strength of competition, thus coupling consumptive and trait‐based effects of ...

The Anatomical Record, EarlyView.Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

The Anatomical Record, EarlyView.Abstract Scientists have been captivated by the ability to regenerate, focusing on uncovering the mechanisms of epimorphic regeneration and applying them to human medicine. The axolotl (Ambystoma mexicanum) has become the most intensively studied model in tetrapod regeneration research, particularly concerning limb regeneration.
