Coywolf, Canis latrans × lycaon , Pack Density Doubles Following the Death of a Resident Territorial Male

摘要: We studied a subset of four radio-collared individuals that were part larger study documenting Coywolf ( Canis latrans × lycaon ; Eastern Coyote) ecology in an urbanized landscape (Cape Cod, Massachusetts), and report on the territory typical sized pack was subdivided roughly half following death breeding male from original ("Centerville") pack. The residents lived winter size (i.e., after pup/juvenile dispersal) three or 19.66 km 2 density 0.15-0.20 individuals/km , as determined by radio-tracking direct observations, with their bordering other monitored packs. Following male, two Coywolves (a young Centerville female pack) shifted respective territories to overlap majority pack's territory. These groups same (three each) but occupied smaller (5.28 12.70 ) within previous combined for new packs estimated at 0.33-0.45 2.2 times greater than former 2.5 (0.38-0.50 when accounting slight (12%) between Our results suggest local Coyote/Coywolf level) may increase given pack, probably because reduced (or lack of) protection territorial boundaries. This finding has particular relevance management programs aimed reducing densities via removal these populations. Further implications exist enriching our understanding trophic dynamics habitats.
