BEHAVIORAL INTERACTIONS BETWEEN COYOTES, CANIS LATRANS, AND WOLVES, CANIS LUPUS, AT UNGULATE CARCASSES IN SOUTHWESTERN MONTANA

Using faecal DNA sampling and GIS to monitor hybridization between red wolves (Canis rufus) and coyotes (Canis latrans).

The US Fish and Wildlife Service's (USFWS) Red Wolf Recovery Program recognizes hybridization with coyotes as the primary threat to red wolf recovery. Efforts to curb or stop hybridization are hampered in two ways. First, hybrid individuals are difficult to identify based solely on morphology. Second, managers need to effectively search 6000 km(2) for the presence of coyotes and hybrids. We dev...

Taxonomic Implications of Morphological and Genetic Differences in Northeastern Coyotes (Coywolves) (Canis latrans × C. lycaon), Western Coyotes (C. latrans), and Eastern Wolves (C. lycaon or C. lupus lycaon)

common in nature, having been documented in amphibians, insects, fish, birds, and especially within closely related plant species (Berger 1973; arnold 1992; Fritz et al. 1994; haddad et al. 1994; Parris et al. 1999; arnold et al. 1999; albert et al. 2006; Schierenbeck and Ellstrand 2009; Meyerson et al. 2010). allendorf et al. (2001) noted that hybridization is more common in fish than in other...

Giardia and Cryptosporidium species and genotypes in coyotes (Canis latrans).

Feces and duodenal scrapings were collected from 22 coyotes (Canis latrans) killed in managed hunts in northeastern Pennsylvania. Polymerase chain reaction (PCR) methods were used to detect Giardia and Cryptosporidium spp. PCR-amplified fragments of Giardia and Cryptosporidium spp. SSU-rRNA genes were subjected to DNA sequence analysis for species/genotype determination. Seven coyotes (32%) wer...

REPRODUCTION IN CAPTIVE WILD-CAUGHT COYOTES (<i>CANIS LATRANS</i>)

Reproduction and Body Condition of California Coyotes (canis Latrans)

Population dynamics and life-history evolution depend heavily on fecundity, which, in the coyote (Canis latrans), can vary substantially according to environmental conditions. Although well studied in the central part of its range, little is known about coyote reproduction in the Mediterranean climates associated with Pacificcoastal North America. I used postmortem examinations of 441 coyotes c...
