Causes and consequences of an unusually male-biased adult sex ratio in an unmanaged feral horse population.
The results support the idea that male-biased ASR in feral ungulate populations may be caused by a combination of high population density and high reproductive output, and suggest that female-biased mortality may be cause by females continuing to reproduce at high density, and thus being more susceptible to resource shortages.
Proximity to humans affects local social structure in a giraffe metapopulation.
A social network from 6 years of systematically collected photographic capture-recapture data is constructed and it is revealed that giraffes have a multilevel social structure and communities that are closer to traditional compounds of Indigenous Masai people express weaker relationship strengths and the giraffe in these communities are more exclusive in their associations.
Fission–fusion dynamics of a megaherbivore are driven by ecological, anthropogenic, temporal, and social factors
Sex- and age-based differences in habitat use reflected nursing mothers’ need for high-quality forage while also protecting their young from predation, and have implications for conservation and management of giraffes and other large-bodied, herd-forming ungulates in heterogeneous environments subject to anthropogenic threats.

Results indicated the ecological effectiveness of Burunge WMA is effectively providing habitat and protection for wild ungulates while generally excluding domestic livestock and provide evidence that CBNRM can have positive effects on wildlife populations, particularly when support to grassroots law enforcement is provided.
Experimental disturbances reveal group-level costs of social instability
This experiment experimentally split socially stable groups of captive zebra finches, and quantified the effects of repeated disturbance events on group foraging efficiency and co-feeding associations when subgroups were recombined, finding that the efficiency of groups to deplete a rich, but ephemeral, resource patch decreased after just a single short disturbance event.
Quantifying the ecological success of a community-based wildlife conservation area in Tanzania
In Tanzania, community-based natural resource management of wildlife occurs through the creation of Wildlife Management Areas (WMAs). WMAs consist of multiple villages designating land for wildlife
Fuzzy structure and spatial dynamics of a declining woodland caribou population
The results indicated that, as the herd declined, subpopulations were disproportionately affected, and it is proposed that changes across time and space are valuable assays of localised demographic change, especially where individuals exhibit spatial hyperdispersion and site fidelity.
