Fisheries Stock Assessment: an inductive science with the Logical form of Primitive Magic
(2010-01-20)
Abstract. A logical analysis of the common fisheries models used in stock assessment has shown that they produce specific
predictions with the logical form of existential statements, fail Karl Popper’s falsifiability ...
Maintenance of Positive Diversity-Stability Relations along a Gradient of Environmental Stress
(2010-04)
Background: Environmental stress is widely considered to be an important factor in regulating whether changes in diversity will affect the functioning and stability of ecological communities. Methodology/Principal Findings: ...
Killer storms: North Atlantic hurricanes and disease outbreaks in sea urchins
(2010-11)
An increase in the incidence of disease in various marine organisms over the past few decades
has been linked to ocean climate change. In Nova Scotia, Canada, mass mortalities of sea urchins,
due to an amoebic disease, ...
Reciprocal Subsidies and Food Web Pathways Leading to Chum Salmon Fry in a Temperate Marine-Terrestrial Ecotone
(2010-04)
Stable isotope analysis was used to determine the relative proportions of terrestrial and marine subsidies of carbon to invertebrates along a tidal gradient (low-intertidal, mid-intertidal, high-intertidal, supralittoral) ...
Natural Selection, Variation, Adaptation, and Evolution: a Primer of Interrelated Concepts
(2010-11)
Natural selection is an elegantly simple concept but one that can manifest in complex ways. I review how the basic model of single-trait viability selection has been extended to more complex forms of selection on multiple ...
Consequences of farmed-wild hybridization across divergent wild populations and multiple traits in salmon
(2010-06)
Theory predicts that hybrid fitness should decrease as population divergence increases. This
suggests that the effects of human-induced hybridization might be adequately predicted from the
known divergence among parental ...
Large-Scale Absence of Sharks on Reefs in the Greater-Caribbean: A Footprint of Human Pressures
(2010-08)
Background: In recent decades, large pelagic and coastal shark populations have declined dramatically with increased fishing; however, the status of sharks in other systems such as coral reefs remains largely unassessed ...
Disease outbreaks associated with recent hurricanes cause mass mortality of sea urchins in Nova Scotia
(2010)
Field observations and laboratory experiments support the hypothesis that disease-induced mass
mortality of the sea urchin Strongylocentrotus droebachiensis can be associated with hurricane
events that introduce a ...
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 ...
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 ...
