REPRODUCTION IN CAPTIVE WILD-CAUGHT COYOTES (CANIS LATRANS)

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...

Nutritional effects on reproductive performance of captive adult female coyotes (Canis latrans).

Interactions between animals and their environment are fundamental to ecological research. Field studies of coyote (Canis latrans) reproductive performance suggest mean litter size changes in response to prey abundance. However, this relationship has been assessed primarily by using carcasses collected from trappers. The objective of this study was to assess whether nutritional manipulation pri...

Integrity of mating behaviors and seasonal reproduction in coyotes (Canis latrans) following treatment with estradiol benzoate.

Coyotes (Canis latrans) are seasonally monestrous and form perennial pair-bonds. Breeding is dominated by each pack's alpha male and female, and both sexes share responsibility for territory defense and pup-rearing. They are also opportunistic predators on domestic livestock and pets. But while dominant adults have been implicated as primary killers, depredation is reduced when coyotes are with...

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...
