A dead giveaway: Foraging vultures and other avian scavengers respond to auditory cues
Ecology and Evolution, 2020 Carrion represents an unpredictable and widely distributed primary food source for vultures and other avian scavengers. Avian scavengers in African savanna ecosystems are reported to rely exclusively on visual stimuli to locate carcasses.

Species Traits Predict Assemblage Dynamics at Ephemeral Resource Patches Created by Carrion
, 2015 Carrion is an ephemeral and spatially patchy resource that supports a diverse subset of species linked to nutrient cycling and the decomposition process.

Journal of Animal Ecology, EarlyView.Our study contributes to our understanding of the effects of interspecific competition in species with biparental care where male and female parents must somehow coordinate their response to interspecific competition. Abstract Interspecific competition is an important evolutionary driver of many species' life histories and behaviours, arising wherever ...

Ecological role of vertebrate scavengers in urban ecosystems in the UK
Ecology and Evolution, 2016 Recent research has demonstrated how scavenging, the act of consuming dead animals, plays a key role in ecosystem structure, functioning, and stability.

An N=8 Superaffine Malcev Algebra and Its N=8 Sugawara [PDF]
, 2001 A supersymmetric affinization of the algebra of octonions is introduced. It satisfies a super-Malcev property and is N=8 supersymmetric. Its Sugawara construction recovers, in a special limit, the non-associative N=8 superalgebra of Englert et al.

Journal of Animal Ecology, EarlyView.For the first time, predation and scavenging networks are directly compared within a single ecosystem. Using an 8‐year dataset of African mammals, including megaherbivores, this study reveals distinct structural rules and body mass constraints, providing a scalable framework for studying consumer–resource dynamics and ecosystem function.

Bioaccumulation of persistent organic pollutants in the deepest ocean fauna [PDF]
, 2017 The Kermadec and Mariana ‘HADES’ expeditions (RV Thomas G. Thompson TN309, and RV Falkor FK141109) were funded through the National Science Foundation (NSF-OCE nos 1130712 and 1140494) and the Schmidt Ocean Institute. S.B.P. was supported by a Fellowship

Journal of Animal Ecology, EarlyView.Predation increases close to habitat edges, but how animals cope with local predation variations remained poorly studied. In a mosaic landscape, lapwings were compensating for increased nest predation close to forests. They acted more aggressively towards an avian predator when nesting close to trees, but comparatively tamer against a mammal.

Extreme Fire as a Management Tool to Combat Regime Shifts in the Range of the Endangered American Burying Beetle [PDF]
, 2020 This study is focused on the population of federally-endangered American burying beetles in south-central Nebraska. It is focused on changes in land cover over time and at several levels of spatial scale, and how management efforts are impacting both the
