You can't go home again: Changes in trophic niche following extinction and recolonization of the New Zealand sea lion

Ecosphere
Recolonization or range expansion of large marine predators can be facilitated by reestablishing formally important trophic linkages within intact coastal marine food webs.

Contrasting abundance and residency patterns of two sympatric populations of transient killer whales (Orcinus orca) in the northern Gulf of Alaska [PDF]

, 2012
Two sympatric populations of “transient” (mammal-eating) killer whales were photo-identified over 27 years (1984–2010) in Prince William Sound and Kenai Fjords, coastal waters of the northern Gulf of Alaska (GOA).

Modelling the surprising recolonisation of an understudied aquatic mammal in a highly urbanised area: fortune favoured the smooth‐coated otter in Singapore

Wildlife Biology, EarlyView.
Ever‐growing human activities present an active and continuing threat to many species throughout the world. Nevertheless, concerted conservation efforts in some regions have balanced these threats and allowed endangered species to recolonise former parts of their original ranges and reverse their decline.

A high‐altitude thermal infrared method for estimating moose abundance and demography in Rocky Mountain National Park, USA

Wildlife Biology, EarlyView.
Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species.

A method to improve size estimates of walleye pollock (Theragra chalcogramma) Atka mackerel (Pleurogrammus monopterygius) consumed by pinnipeds: digestion correction factors applied to bones and otoliths recovered in scats [PDF]

, 2004
The lengths of otoliths and other skeletal structures recovered from the scats of pinnipeds, such as Steller sea lions (Eumetopias jubatus), correlate with body size and can be used to estimate the length of prey consumed.

Citizen science project on urban canids provides different results from camera traps but generates interest and revenue

Wildlife Biology, EarlyView.
As urbanization increases, wildlife increasingly encounters people. Coyotes Canis latrans and red foxes Vulpes vulpes are two canid species that have readily adapted to urban environments. Citizen science has emerged as a low‐cost method of collecting data on urban‐adapted species that can benefit management agencies but may provide different results ...

Dietary shift of the common leopard Panthera pardus in and around Bani Wildlife Sanctuary, western Himalayas: implications for conservation and human–wildlife conflict

Wildlife Biology, EarlyView.
Understanding the dietary patterns of apex predator like the common leopard Panthera pardus is essential for evaluating their ecological role, particularly in landscapes where human–wildlife conflict is prevalent. In this context, this study investigates the seasonal diet composition of the common leopard in and around the Bani Wildlife Sanctuary, a ...
