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

open access: yesWildlife 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 ...

A systematic review of the agents and factors influencing California sea lion health

open access: yesFrontiers in Marine Science
Marine ecosystems are increasingly affected by climate-driven disturbances such as sea-level rise, marine heatwaves, ocean acidification, and pollution. Monitoring sentinel species is essential for detecting long-term environmental changes and informing ...

The First World War at Sea: Death, Commemoration and Cultural Remembrance

open access: yesHistory, EarlyView.
Abstract Despite the ever‐increasing body of work devoted to war memorials, national days of remembrance and the commemoration of the First World War in Britain, academic focus remains firmly on the commemoration of the First World War on land. Yet, while the number of people who died at sea paled in comparison to their counterparts on the battlefield ...

Inflation and deflation pressure-volume loops in anesthetized pinnipeds confirms compliant chest and lungs

open access: yesFrontiers in Physiology, 2014
We examined structural properties of the marine mammal respiratory system, and tested Scholander’s hypothesis that the chest is highly compliant by measuring the mechanical properties of the respiratory system in five species of pinniped under anesthesia

Persistent Contaminants and Herpesvirus OtHV1 Are Positively Associated With Cancer in Wild California Sea Lions (Zalophus californianus)

open access: yesFrontiers in Marine Science, 2020
The prevalence of cancer in wild California sea lions (Zalophus californianus) is one of the highest amongst mammals, with 18–23% of adult animals examined post-mortem over the past 40 years having urogenital carcinoma. To date, organochlorines, genotype

An Overview of the Rock Art of AlUla: Tracing Changes in Content and Form Across 12,000 Years of Human History

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Between 2018 and 2021, the Identification and Documentation of Immovable Heritage Assets (IDIHA) Project recorded over 19,000 rock art panels in the AlUla (al‐‘Ulā) region of north‐western Saudi Arabia. This study presents a chronological assessment of the corpus, drawing on superimpositions, datable motifs, inscriptions, and varnish formation,

Head-mounted accelerometry accurately detects prey capture in California sea lions

open access: yesAnimal Biotelemetry, 2021
Detecting when and where animals feed is key to understanding their ecophysiology, but our ability to collect these data in marine mammals remains limited.

Taxonomic, Phylogenetic and Functional Diversity of Mammals Across a Nationwide Protected Area Network

open access: yesAnimal Conservation, EarlyView.
Using camera‐trap data from 26 protected across Tanzania, we show that greater landscape heterogeneity and stronger protection are associated with higher mammal species richness and, in turn, functionally and phylogenetically richer mammal assemblages. Greater landscape heterogeneity appears to favour generalist species while stronger protection seems ...

Fatty acids in plasma of California sea lion pups (Zalophus c. californianus) from Los Islotes, Baja California Sur, Mexico

open access: yesCiencias Marinas, 2003
 Nutritious fats include all the lipids ingested as food and are composed mainly of triglycerides mixed with smaller quantities of other lipids. Fatty acids (FA) constitute the part of most nutritious interest in triglycerides.

Human Recreation and Fire History Shape Landscape Connectivity for an Endangered Forest Carnivore

open access: yesAnimal Conservation, EarlyView.
Roads and trails can impede wildlife movement, but their permeability varies with human use and fire history. We combined GPS telemetry from 45 endangered southern Sierra Nevada fishers (Pekania pennanti) with smartphone‐derived human mobility data to estimate crossing probability across road and trail segments. Fishers were about 2.5 times more likely
