To assist in evaluating habitat retention options, the abundance of northern flying squirrels (Glaucomys sabrinus) and North American red squirrels (Tamiasciurus hudsonicus) wer examined in 2005 and again in 2010 across a gradient of mountain pine beetle ... see more

Field observations using chronosequences are helpful to study vegetation succession. This method allows to establish comparisons based on soil composition, stand structure, micro- and macrofossil remains from sites of different ages but on similar edaphic... see more

Despite the great importance of the level of biodiversity and endemism that the EquatorialSeasonal Tropical dry Forest hosts, many of its areas remain unexplored. Here we present the resultsof the field evaluations carried out between 2014 and 2018 along ... see more

This study quantified characteristics related to tree condition and deterioration in stands affected by the mountain pine beetle (MPB, Dendroctonus ponderosae) or wildfire. The stands evaluated were representative of a range of conditions present in the S... see more

The biomass potential of eight high yielding maize cultivars was studied in the sub-boreal climate of southern Finland. The effects of harvest date on lignin and sugar production, biomass yield, mineral element composition, bioenergy potential and soil nu... see more

On the average, during boreal winter (December through February), the occurrence of El Niño/Southern Oscillation (ENSO) results in enhanced or diminished precipitation in various regions of the Americas. Anomalous convective ac... see more

We examined the premise that changing abundance and environmental conditions influence the seasonal dispersion and distribution of migratory tundra caribou (Rangifer tarandus groenlandicus). The Ahiak herd’s (north-central Nunavut Territory, Canada) calvi... see more

A hierarchical approach to critical habitat identification has been proposed in the draft National Recovery Strategy for the Woodland Caribou (Rangifer tarandus caribou), Boreal Population. This approach proposes that critical habitat for boreal caribou b... see more
