A guild of three and possibly five tip moths
(Rhyacionia spp.) occurs on ponderosa pine (Pinus ponderosa)
in southeastern Montana, northwestern South Dakota, and
southwestern North Dakota. Trapping results indicated that
many of these species may...

Wildlife habitat mapping has evolved at a rapid pace over the last few decades. Beginning with simple, often subjective,
hand-drawn maps, habitat mapping now involves complex species distribution models (SDMs) using
mapped predictor variables...

For effective species management, understanding population structure and distribution is critical. However, quantifying population structure is not always straightforward. Within the Southern Hemisphere, the blue whale (Balaenoptera musculus)...

For many organisms, the reconstruction of source-sink dynamics is hampered by limited knowledge of the spatial
assemblage of either the source or sink components or lack of information on the strength of the linkage for any source-sink
pair. In...

Early theoretical models for the evolution of male-female
pairing were based largely on studies of birds. These models
assumed that biparental care of eggs and young was an
essential component of pairing. However, male-female pairing
is also a...

Spatial variation in the diet of the northern spotted owl (Strix occidentalis caurina) influences owl home ranges, and understanding this relationship will aid managers in forest management prescriptions that influence spotted owl recovery. This...

Accurate estimation of historical abundance provides an
essential baseline for judging the recovery of the great whales.
This is particularly challenging for whales hunted prior to
twentieth century modern whaling, as population-level catch...

Differences in the chemical composition of calcified skeletal structures (e.g. shells, otoliths) have proven useful for
reconstructing the environmental history of many marine species. However, the extent to which ambient
environmental conditions...

We lack a deep understanding of genetic and metabolic attributes specializing in microbial consortia for initial and subsequent waves of colonization of our body habitats. Here we show that phylogenetically interspersed bacteria in Clostridium...

Fungal mitospores may function as dispersal units and/ or spermatia, and thus play a role in
distribution and/or mating of species that produce them. Mitospore production in
ectomycorrhizal (EcM) Pezizales is rarely reported, but here we document...

Rapid eruption of submarine lava flows during formation of the Caribbean plateau correlates closely with
ocean anoxic event 2 (OAE2), which bracketed the Cenomanian/Turonian boundary (~93.5 Ma). These events
also correspond with a positive...

In June 1987 the geostropic flow in the coastal transition zone off northern California (between 50 and 150 km off the coast from Point Reyes to just north of Cape Mendocino) was dominated by a well-defined, southward-meandering current. Three...
