Interference competition with wolves Canis lupus is hypothesized to limit the distribution and abundance of coyotes Canis latrans, and the extirpation of wolves is often invoked to explain the expansion in coyote range throughout much of North America. We used spatial, seasonal and temporal heterogeneity in wolf distribution and abundance to test the hypothesis that interference competition wit...

BACKGROUND The influence of policy on the incidence of human-wildlife conflict can be complex and not entirely anticipated. Policies for managing bear hunter success and depredation on hunting dogs by wolves represent an important case because with increasing wolves, depredations are expected to increase. This case is challenging because compensation for wolf depredation on hunting dogs as comp...

The original Wolf sum [D. Wolf et al., J. Chem. Phys. 110 (1999) 8254–8282] was modified to account for the effect of charge overlap in an empirical manner in order to correct the direct 1/r coulomb interaction in covalent systems. The resulting modified Wolf sum takes a form that is similar to the original one. More importantly, the inclusion of the charge overlap effect does not introduce any...

Mitochondrial DNA (mtDNA) D-loop control region sequences ranging In length from 583 to 598 bp were determined for eight Japanese wolf specimens (Canis lupus hodophilax Temminck, 1839) collected from several sites and compared with 105 haplotypes from the domestic dog (C. lupus familiaris) and continental grey wolf (C. lupus lupus). Also, a 197-bp mtDNA sequence was amplified from archaeologica...

Information is sparse about aspects of female wolf (Canis lupus) breeding in the wild, including age of first reproduction, mean age of primiparity, generation time, and proportion of each age that breeds in any given year. We studied these subjects in 86 wolves (113 captures) in the Superior National Forest (SNF), Minnesota (MN), during 1972-2013 where wolves were legally protected for most of...

Four groups of behavioral scientists with divergent theoretical persuasions--43 sociobiologists, 25 behaviorists, 35 personality psychologists, and 16 human developmentalists--showed significantly different mean scores on two measures of philosophical assumptions: the World Hypothesis Scale (WHS) and the Organicism-Mechanism Paradigm Inventory (OMPI). The OMPI, which appears to be more psychome...

Ancistrocerus waldenii waldenii (Viereck 1906) is newly recorded from West Greenland. This is a new northern limit for the species.

We used rendezvous site locations of wolf (Canis lupus) packs recorded during 1996–2006 to build a predictive model of gray wolf rendezvous site habitat in Idaho, USA. Variables in our best model included green leaf biomass (Normalized Difference Vegetation Index), surface roughness, and profile curvature, indicating that wolves consistently used wet meadow complexes for rendezvous sites. We th...
