Requirements for maintenance and live weight gain of moose and wapiti calves during winter

Rangifer, 1996
Energy requirements of moose (Alces alces) and wapiti (Cervus elaphus) calves were compared from December to February to determine whether metabolic requirements were lower in a boreal-adapted than in a parkland-adapted wild cervid.

The impacts of biological invasions

Biological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

The As and Bs of titi monkey linguistics: why emotional communication is not the enemy

Biological Reviews, EarlyView.
ABSTRACT The alarm call sequences of titi monkeys (genera Plecturocebus, Callicebus and Cheracebus) have sparked important debates over whether they exhibit parallels with human language. Some researchers consider these sequences to involve both semantics and syntax, while others argue that the sequences convey semantic information without syntax.

Impact of low testing numbers on chronic wasting disease apparent prevalence

Prion
Chronic wasting disease (CWD) is a fatal, neurodegenerative disease of cervids, and its management heavily relies on diagnostic testing. Test results are commonly used to calculate ‘apparent prevalence’ (AP) – the percent of animals tested for CWD (CWD ...

Accelerated high fidelity prion amplification within and across prion species barriers.

PLoS Pathogens, 2008
Experimental obstacles have impeded our ability to study prion transmission within and, more particularly, between species. Here, we used cervid prion protein expressed in brain extracts of transgenic mice, referred to as Tg(CerPrP), as a substrate for ...

Review on PRNP genetics and susceptibility to chronic wasting disease of Cervidae

Veterinary Research, 2021
To date, chronic wasting disease (CWD) is the most infectious form of prion disease affecting several captive, free ranging and wild cervid species. Responsible for marked population declines in North America, its geographical spread is now becoming a ...

Reading hominin life history in fossil bones and teeth: methods to test hypotheses regarding its evolution

Biological Reviews, EarlyView.
ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

Host, vector, and parasite dynamics: exploring intrinsic and extrinsic factors shaping tick‐borne filarial nematode transmission

Biological Reviews, EarlyView.
ABSTRACT Tick‐borne filarial nematodes are a complex and understudied group of parasites that rely on ticks for transmission in vertebrates. This review examines how intrinsic and extrinsic factors may influence the successful transmission of filarial nematodes in tick vectors, drawing insights from extensively studied haematophagous dipteran vector ...

Camera collars reveal macronutrient balancing in free‐ranging male moose during summer

Ecology and Evolution
Understanding how the nutritional properties of food resources drive foraging choices is important for the management and conservation of wildlife populations.
