The objective of this study was to test the hypothesis that distance is an important factor affecting attitudes towards wolves, i.e. people living far from wolf territories have more positive attitudes towards wolf conservation than those living[...]

Our failure to understand or predict evolutionary dynamics under climatic change precludes much conservation planning. Evolution may reduce extinction under global warming, but few studies have explored how genetic covariation, the norm for most[...]

Since 1960 the range occupied by New England cottontails (NEC, Sylvilagus transitionalis) in the northeastern United States has declined dramatically Populations in some regions are known to be vulnerable to extirpation, but little was known abo[...]

Based on a series of 11 abundance estimates over 23 years, the western Arctic population of bowhead whale (WABW) has recovered substantially since it was listed under the US Endangered Species Act. We evaluate extinction risk for WABW to determi[...]

Habitat reserves are a common strategy used to ensure viability of wildlife populations and communities. The efficacy of reserves, however, is rarely empirically evaluated. We examined the likelihood that small (650 ha), isolated habitat reserve[...]

The negative consequences of lead shot ingestion have been demonstrated in captive birds, and the prevalence of embedded shot has been measured in wild waterfowl several times. However, the long-term consequences of these two indirect outcomes o[...]

Efficiency in biomonitoring studies is essential to maximize return (i.e. useful data) for investment (e.g. time, training, personnel). Here, we test several options for reducing data resolution when streamlining monitoring protocols, and use th[...]

Coastal rainforests of southeast Alaska have relatively simple species composition but complex structures with high diversity of tree ages, sizes and forest canopy layers, and an abundant understory plant community. Wildlife and fisheries resour[...]

The model of 'ecological forestry' has evolved as a part of the development of the concept of ecosystem management. 'Ecological forestry' emphasises that manipulation of a forest ecosystem should consider, and as far as practicable work within t[...]

Backcross breeding has provided a viable means to restore American chestnut (Castanea dentata (Marsh.) Borkh.) to eastern North American forests, where the foundation species was essentially extirpated by an introduced pathogen. With the prospec[...]

Forest stands are the basic planning units of managed forest landscapes, and the structural composition of these units is important for conservation of biodiversity. We present a methodological approach for identification and mapping of importan[...]
