Texas horned lizards (Phrynosoma cornutum; hereafter THL) were once abundant throughout Texas; however, their distribution and abundance have decreased, currently they are listed as a threatened species in the state. Detection of THL can be difficult because cryptic nature sporadic distribution. Using indirect signs such fecal pellets (i.e., scat) to determine occupancy is widely practiced surv...

Over the past 10 years, we have examined hierarchical genetic structure in the three geographically-defined subspecies of spotted owl (Strix occidentalis) to define relationships among subspecies and quantify variation within and among regional and local populations. Sequences (522 bp) from domain I and II of the mitochondrial control region were analyzed for 213 individuals from 30 local breed...

Objectives Rugby Union has adapted the Sports Concussion Assessment Tool (SCAT) into an abridged off-field concussion screen and complete SCAT is used during diagnostic screens performed after head impact events. No firm guidelines exist as to what should be considered “abnormal” warrant further evaluation. This study evaluates performances in 13,479 baseline assessments, proposes clear referen...

Aim . To compare the expression of enzymes ceramide de novo synthesis pathway in cardiac adipose tissue (AT) and blood vessels patients with coronary artery disease (CAD) acquired heart defects. Material methods The study included 20 CAD 18 aortic stenosis/regurgitation. Biopsies subcutaneous, epicardial, perivascular AT (SCAT, EAT, PVAT, respectively) were obtained during surgery. Quantitative...

A new autosomal recessive mouse mutation, scat (severe combined anemia and thrombocytopenia), causes intermittent episodes of severe bleeding in the homozygote. At birth, affected mice are pale with intradermal petechiae and bruises on exposed surfaces. Central nervous system (CNS) bleeding occurs in 22% of the mice. Gastrointestinal (GI) hemorrhaging and splenomegaly are noted in moribund mice...

Recently, detection dogs have been utilized to collect fecal samples from cryptic and rare mammals. Despite the great promise of this technique for conservation biology, its broader application has been limited by the high cost (tens to hundreds of thousands of dollars) and logistical challenges of employing a scat-detection dog team while conducting international, collaborative research. Throu...

Large cats feeding habits have been studied through two main methods: scat analysis and the carcasses of prey killed by monitored animals. From November 2001 to April 2004, we studied jaguar predation patterns using GPS telemetry location clusters on a cattle ranch in southern Pantanal. During this period, we recorded 431 carcasses of animals preyed upon by monitored jaguars. Concurrently, we c...

The 1970 SS Arrow incident in Chedabucto Bay, Nova Scotia (NS) was a milestone event Canada's oil spill response history and has been used by Environment Climate Change Canada (ECCC) for ongoing research almost 50 years. In August of 2015, the remaining sunken section ARROW released Bunker C from its tanks some sections shorelines impacted were affected once again. Canadian Coast Guard led 2015...

Population genetics plays an increasingly important role in the conservation and management of declining species, particularly for defining taxonomic units. Subspecies are recognized by several conservation organizations and countries and receive legal protection under the US Endangered Species Act (ESA). Two subspecies of spotted owls, northern (Strix occidentalis caurina) and Mexican (S. o. l...
