Feral equids in the USA have seldom been studied with telemetry collars due to animal safety concerns. Our systematic review found that reported natural mortality rates of telemetry-collared wild and feral equids are lower than routinely collared North American ungulates; however, collar-related complications (or lack thereof) are rarely reported in the primary literature. We recommend explicit reporting of telemetry collar complication for all species to better understand the relative risk of collaring equids. Photograph by Jacob D. Hennig.

Obtaining reliable estimates of nocturnal-primate abundance and the effect of habitat type on abundance estimates is challenging because of their cryptic behaviour. We aimed to explore the necessary survey effort required to obtain reasonable estimates by using N-mixture hierarchical models to run simulations. We provide recommendations on survey effort and preliminary surveys to gauge the effort required to obtain non-bias estimates of abundance and the effect of the habitat type on abundance estimates.

In Australia, kangaroos are known to occur within peri-urban areas, where they can be a source of human–wildlife conflict. This study assessed the home range and habitat use by peri-urban wallaroos, and showed that individuals avoided human features within the landscape. This behaviour reduces the potential for conflict for this species, and highlights the importance of linking natural habitat patches to support the persistence of large mammals in our increasingly urbanised environment.

Migratory animals with slow generation times are at risk of population decline in a changing climate. This study aimed to assess which climatic factors affected the timing of migration for a cave-dwelling species of bat in South Africa. Results showed that migration was affected most by changing night length, likely making this species vulnerable to population decline due to resource mismatches. Photograph by Mariëtte Pretorius.

Translocations are an important conservation tool for Australian critical weight-range mammals. We assessed the success of translocations of the greater bilby to two sites within South Australia, and found that a population co-occurring with feral cats and European rabbits was declining because of a lack of recruitment into the adult population. We contend that the lack of recruitment in this population was due to predation by feral cats on subadult bilbies. Our results suggest that the bilby is rather tolerant of previous habitat disturbance, provided exotic predators are not present, and that safe havens for this species should exclude both red foxes and feral cats.

We evaluated the influence of translocation distance, sex, age and landscape context on translocation success of American black bear (Ursus americanus) involved in nuisance behaviour, by using 37 years of data from Wisconsin, USA. Repeated nuisance behaviour following translocation events was rare (192 of 1457 events) and increasing translocation distance reduced the probability of bears being recaptured at their capture site (i.e. returning). Landscape context also influenced the probability of returning, which allowed us to estimate age-, sex- and landscape-specific return probabilities for given translocation distances, which can help managers increase translocation success.

Cattle egrets are widespread on islands and continents, and often swallow animal prey whole. We share the first evidence of rodent carcasses being moved by cattle egrets between islands. Land managers and biosecurity professionals who are actively keeping areas rodent free, such as islands, should be made aware of the possibility that cattle egrets could introduce rodent carcasses to rodent-free areas.
