Diazotrophic bacteria respond to Saharan dust additions
(2012)
Three bioassay experiments were performed to study the effects of nutrient and Saharan dust additions on natural diazotrophic communities in the tropical North Atlantic Ocean. Samples for nucleic acid analysis were collected ...
Surviving historical Patagonian landscapes and climate: molecular insights from Galaxias maculatus
(2010-03)
Background: The dynamic geological and climatic histories of temperate South America have played important roles in shaping the contemporary distributions and genetic diversity of endemic freshwater species. We use ...
Inferring Animal Densities from Tracking Data Using Markov Chains
(2013-04)
The distributions and relative densities of species are keys to ecology. Large amounts of tracking data are being collected on a wide variety of animal species using several methods, especially electronic tags that record ...
Primiparous and multiparous females differ in mammary gland alveolar development: implications for milk production
(2012-08)
Mammary gland capacity is influenced by the number of secretory cells in the gland, the activity
of those cells and the size and arrangement of the alveoli that they form. Although reproductive
experience has been shown ...
Food-Web Structure of Seagrass Communities across Different Spatial Scales and Human Impacts
(2011-07)
Seagrass beds provide important habitat for a wide range of marine species but are threatened by multiple human impacts in coastal waters. Although seagrass communities have been well-studied in the field, a quantification ...
Relative risks of inbreeding and outbreeding depression in the wild in endangered salmon
(2011-09)
Conservation biologists routinely face the dilemma of keeping small, fragmented populations
isolated, wherein inbreeding depression may ensue, or mixing such populations, which may exacerbate
population declines via ...
Genomic islands of divergence and their consequences for the resolution of spatial structure in an exploited marine fish
(2013-04)
As populations diverge, genomic regions associated with adaptation display elevated
differentiation. These genomic islands of adaptive divergence can inform conservation efforts in
exploited species, by refining the ...
Breeding Bird Surveys at Alexandra Fiord, Ellesmere Island, Nunavut (1980-2008)
(2010-09)
Long-term monitoring of bird populations in the Arctic is of considerable interest as this area
is experiencing rapid climate warming; however, multi-decadal studies in the Canadian High Arctic
are rare. Over five summers ...
Improving Evolutionary Models for Mitochondrial Protein Data with Site-Class Specific Amino Acid Exchangeability Matrices
(2013-01)
Adequate modeling of mitochondrial sequence evolution is an essential component of mitochondrial
phylogenomics (comparative mitogenomics). There is wide recognition within the field that
lineage-specific aspects of ...
Both Geography and Ecology Contribute to Mating Isolation in Guppies
(2010-12)
Local adaptation to different environments can promote mating isolation - either as an
incidental by-product of trait divergence, or as a result of selection to avoid maladaptive mating.
Numerous recent empirical examples ...
