Hunting as anthropogenic sink of biomass or source of carrion? A brief case study based on German hunting bags

open access: yesWildlife Biology, EarlyView.
Dead biomass is a crucial nutrient source for ecosystems. Although hunting residues can subsidize numerous scavenging organisms and are known to drive important zoogeochemical processes at very different scales in the ecosystem, this has received little attention.

Livestock grazing and geodiversity modulate wild herbivore distributions in an African community conservation area

open access: yesWildlife Biology, EarlyView.
The rapid decline of African wildlife populations demands immediate action to mitigate further losses and restore ecosystems. A key factor influencing wildlife distribution is the relationship between the energetic needs of species and the availability of forage, both in terms of quality and quantity.

Facing Truths About Population Management

open access: yesZoo Biology, EarlyView.
Populations of wildlife, and domestic animals have large sinks for surplus animals. By contrast, zoos don't. Humans in industrialized societies are socialized with companion animals, i.e. surplus (i.e., typically denied reproduction) originating from unseen breeding cores.

Cryptic variation within and among islands in the ultraviolet reflectance of lizard throat coloration

open access: yesJournal of Animal Ecology, EarlyView.
Identifying the existence of ‘cryptic’ morphs is critical in animal ecology for providing a basis for accurately testing links between phenotype and environment. This study identifies the existence of previously undocumented variation in UV reflectance in Aegean wall lizards that likely has novel behavioural and evolutionary implications within this ...

Beggars can't be choosers: Competitive dominance and size‐dependent resource investment jointly constrain partner associations in a multispecies mutualism

open access: yesJournal of Animal Ecology, EarlyView.
This study demonstrates that competition structures access to mutualistic partners that vary in value. Competitively dominant ants disproportionately invest in larger aphid colonies that produce more honeydew, restricting subordinate ants to smaller colonies.
