Personality are related to risk-taking exploration, which turn correlate with individuals' daily responses, decisions, fitness.

For wolves newly repatriated Colorado, individual factors likely prove important for adapting their new homes as well needs of people cohabiting Animal human need investigated jointly long-term success conservation initiatives.

ABSTRACT Species' future distributions are commonly predicted using models that link the likelihood of occurrence individuals to environment. Although animals' movements influenced by physical and non‐physical landscapes, for example related individual experiences such as space familiarity or previous encounters with conspecifics, species distribution developed from observations unknown cannot integrate these latter variables, turning them into ‘invisible landscapes’. In this theoretical study, we address how overlooking landscapes’ impacts estimation habitat selection thereby projection distributions. Overlooking attraction towards some ‘invisible’ variable consistently led overestimating strength selection. Consequently, projections population were also biased, animals following changes in preferred less than predicted. Our results reveal an overlooked challenge faced correlative based on observation individuals, whose past experience environment is definition not known. Mechanistic modeling integrating cognitive processes underlying movement should be developed.

Abstract The colonization of suitable yet unoccupied habitat due to natural dispersal or human introduction can benefit recovery threatened species. Predicting suitability and conflict potential areas facilitate conservation planning. Planning for reintroduction gray wolves ( Canis lupus ) the US state Colorado is underway. Assessing which occupancy sites minimize likelihood human–wolf during events seasonal movements critical success this initiative. We used a spatial absorbing Markov chain (SAMC) framework, extends random walk theory probabilistically accounts both movement behaviour mortality risk, compare viability (public lands >500 km 2 minimally meet wolf pack range area). SAMC framework produced spatially explicit predictions dispersal, philopatry risk ahead recolonization prior efforts. Our model included: (1) resistance based on terrain, roads housing density; (2) (absorption) livestock presence, social tolerance, land ownership boundaries; (3) site fidelity quality. Using model, we compared 21 public units by deriving of: (A) relative survival time outside each site, (B) intensity use retention within (C) probability adjacent lands. also predicted mapped hotspots associated with site. Among assessed, complex USFS Wilderness near Aspen, chiefly Hunter‐Fryingpan Collegiate Peaks areas, had best overall rankings when comparing metric. area balances high‐quality, well‐connected relatively low density high tolerance.
