Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

Field immobilisation of adult Weddell seals using intramuscular butorphanol and midazolam

Veterinary Record, EarlyView.
Abstract Background When working with free‐ranging phocid seals, methods of chemical immobilisation require ongoing refinement to reduce complications, particularly apnoea, during research procedures. Methods Adult Weddell seals (n = 20) at Cape Crozier, Antarctica, were chemically immobilised with intramuscular injection of butorphanol and midazolam ...

‘Using anuran community diversity and Pseudacris crucifer to predict landscape quality across a land use gradient'

Wildlife Biology, EarlyView.
As human‐modified landscape and climate changes proliferate, maintaining biodiversity and understanding the function and quality of available habitat is imperative. As anurans (frogs/toads) such as Pseudacris crucifer, can be an indicator species of habitat quality and ecosystem productivity, studying the anuran community in a mixed‐land use region ...

The Recolonisation of the Piketberg Leopard Population: A Model for Human–Wildlife Coexistence in a Changing Landscape

Conservation
Important metapopulation dynamics are disrupted by factors such as habitat loss, climate change, and human-induced mortality, culminating in isolated wildlife populations and threatening species survival.

Suitable habitat of Himalayan wolf in Upper Mustang, Annapurna Conservation Area, Nepal

Wildlife Biology, EarlyView.
Decades ago, the Himalayan wolf Canis lupus chanco, a genetically distinct sub‐species of the gray wolf Canis lupus, faced persecution by local communities in the Nepalese Himalayas. Recently, wolf populations have returned and recolonized, sparking concerns about conflicts over livestock depredation, and emphasizing the urgent need for comprehensive ...

Leopard in a tea-cup: A study of leopard habitat-use and human-leopard interactions in north-eastern India

PLOS ONE, 2017
There is increasing evidence of the importance of multi-use landscapes for the conservation of large carnivores. However, when carnivore ranges overlap with high density of humans, there are often serious conservation challenges. This is especially true in countries like India where loss of peoples' lives and property to large wildlife are not uncommon.

Evaluating machine learning models for multi‐species wildlife detection and identification on remote sensed nadir imagery in South African savanna

Wildlife Biology, EarlyView.
This research paper investigates the efficacy of leading machine learning (ML) models for detecting and identifying ungulate species in African savanna using nadir imagery from unmanned aerial vehicles (UAVs). Traditional aerial counting methods, while widely used, suffer from significant limitations in accuracy and precision, in part due to human ...

Habitat suitability of common leopard in northern Pakistan

Ecosphere
Habitat fragmentation and loss are considered primary threats to common leopards (Panthera pardus) across their geographical range. We investigated anthropogenic and environmental factors influencing the habitat suitability of leopards in northern ...

Camera trap distance sampling for density estimation of tiger prey in a Sumatran ecosystem restoration concession

Wildlife Biology, EarlyView.
Estimating prey species densities is critical for implementing effective tiger Panthera tigris recovery strategies. Several statistical models exist for density estimation of unmarked species from camera trap data, all of which rely on the random placement of cameras.
