Article
Wildlife around cities bioaccumulate multiple harmful environmental pollutants associated with human activities. Exposure severity can vary based on foraging behaviour and habitat use, which can be examined to elucidate exposure pathways. Carnivores can play vital roles in ecosystem stability but are particularly vulnerable to bioaccumulation of po...
Article
Urbanisation and habitat loss are major threats to wildlife populations globally. Understanding how species respond to anthropogenic changes is therefore crucial to mitigating threats and developing conservation management strategies. We examined the habitat use of five fishing cats (Prionailurus viverrinus) in Sri Lanka’s capital city, Colombo, a...

As natural habitat is progressively transformed, effective wildlife conservation relies on understanding the phenotypic traits that allow select species to persist outside of protected areas. Through behavioural flexibility such species may trade off abundant resources with risks, both real and perceived. As highly adaptable meso-carnivores, caraca...
Article
Anellovirus infections are highly prevalent in mammals but prior to this study only a handful of anellovirus genomes had been identified in members of the Felidae family. Here characterise anelloviruses in pumas (Puma concolor), bobcats (Lynx rufus), Canada lynx (Lynx canadensis), caracals (Caracal caracal) and domestic cats (Felis catus). The comp...

Article
Landscape connectivity is essential to conserving resilient wildlife populations in the Anthropocene. Maintaining connectivity requires preserving or restoring patches of habitat, accounting for the behavioral factors that determine movement between patches and mitigating threats. We measured natural and anthropogenic features that influence moveme...
Article

Urban development has major impacts on connectivity among wildlife populations and is thus likely an important factor shaping pathogen transmission in wildlife. However, most investigations of wildlife diseases in urban areas focus on prevalence and infection risk rather than potential effects of urbanisation on transmission itself. Feline immunode...

Urbanisation radically changes habitats and alters available resources. Populations of large, highly mobile species are often extirpated at the urban-wildland interface, while species like mesocarnivores may thrive by capitalising on changes in prey abundance. We investigated the diet of the caracal (Caracal caracal), a medium-sized felid inhabitin...

Background: Wild carnivores living alongside humans and domestic animals are vulnerable to changes in the infectious disease dynamics in their populations. The aims of this study were to determine the prevalence and diversity of selected tick-borne pathogens (TBPs) of veterinary and/or zoonotic concern in wild populations of caracals (Caracal cara...

ContextIn human-dominated landscapes, habitat fragmentation and barriers to movement can interrupt gene flow. While often considered at a local extent, regional analyses are also needed to reveal broader landscape-mediated population processes.Objectives To explore the relationship between patterns of gene flow and fragmentation resulting from urba...

We investigated Toxoplasmosis gondii antibody seroprevalence in free-ranging caracals (Caracal caracal) in Cape Town, South Africa, from 2014 to 2017. Seropositivity was 83% (24/ 29), which is substantially higher than that detected in sympatric feral domestic cat (Felis catus) populations. The impact of this pathogen on local human and wildlife co...
Article
Urbanization is a major factor driving habitat fragmentation and connectivity loss in wildlife. However, the impacts of urbanization on connectivity can vary among species and even populations due to differences in local landscape characteristics, and our ability to detect these relationships may depend on the spatial scale at which they are measur...

Smacoviruses are small circular single-stranded DNA viruses that appear to be prevalent in faeces of a range of animals and have also been found in a few insect species. In this study, we report the first viral genomes from faeces of free-roaming wild felids on two continents. Two smacoviruses were recovered from the faeces of two North American bo...

Anticoagulant rodenticides (ARs) are indiscriminate toxicants that threaten non-target predatory and scavenger species through secondary poisoning. Accumulating evidence suggests that AR exposure may have disruptive sublethal consequences on individuals that can affect fitness. We evaluated AR-related effects on genome wide expression patterns in a...

Understanding how human activities influence immune response to environmental stressors can support biodiversity conservation across increasingly urbanizing landscapes. We studied a bobcat (Lynx rufus) population in urban southern California that experienced a rapid population decline from 2002-2005 due to notoedric mange. Because anticoagulant rod...
Article
Understanding the environmental contributors to population structure is of paramount importance for conservation in urbanized environments. We used spatially explicit models to determine genetic population structure under current and future environmental conditions across a highly fragmented, human-dominated environment in Southern California to as...
Article
Importance: Cross-species transmission episodes can be singular, dead-end events or can result in viral replication and spread in the new species. The factors that determine which outcome will occur are complex, and the risk of new virus emergence is therefore difficult to predict. Here we use molecular techniques to evaluate transmission, fitness...

The extinction vortex is a theoretical model describing the process by which extinction risk is elevated in small, isolated populations owing to interactions between environmental, demographic, and genetic factors. However, empirical demonstrations of these interactions have been elusive. We modelled the dynamics of a small mountain lion population...

Anticoagulant rodenticides (ARs) are increasingly recognized as a threat to nontarget wildlife. High exposure to ARs has been documented globally in nontarget predatory species and linked to the high prevalence of an ectoparasitic disease, notoedric mange. In southern California, mange associated with AR exposure has been the proximate cause of a b...

Urbanization profoundly impacts animal populations by causing isolation, increased susceptibility to disease, and exposure to toxicants. Genetic effects include reduced effective population size, increased population substructure, and decreased adaptive potential. We investigated the influence that urbanization and a disease epizootic had on the po...

Large carnivores can be particularly sensitive to the effects of habitat fragmentation on genetic diversity [1, 2]. The Santa Monica Mountains (SMMs), a large natural area within Greater Los Angeles, is completely isolated by urban development and the 101 freeway to the north. Yet the SMMs support a population of mountain lions (Puma concolor), a v...

Mountain lions (Puma concolor) throughout North and South America are infected with puma lentivirus B (PLVB). A second, highly divergent lentiviral clade, PLVA, infects mountain lions in southern California and Florida. Bobcats in these two geographic regions are also infected with PLVA, and to date, this is the only strain of lentivirus identified...

Abstract Notoedric mange was responsible for a population decline of bobcats (Lynx rufus) in 2 Southern California counties from 2002-2006, and is now reported to affect bobcats in Northern and Southern California. With this study, we document clinical laboratory and necropsy findings for bobcats with mange. Bobcats in this study included free-rang...
Article
Notoedric mange in felids is a devastating disease caused by a hypersensitivity reaction to the mite Notoedres cati. The burrowing of the mite causes intense pruritis resulting in self-mutilation, secondary bacterial infection, and often death of affected felids if left untreated. Our understanding of how notoedric mange is maintained in felid popu...
