Density-independent and density-dependent variables both affect the spatial distributions of species. However, their effects are often separately addressed using different analytical techniques. We apply a spatially explicit regression framework that incorporates localized, interactive and threshold effects of both density-independent (water temperature) and density-dependent (population abundance) variables, to study the spatial...

Environmental variability is increasingly recognized as a primary determinant of year-class strength of marine fishes by directly or indirectly influencing egg and larval development, growth, and survival. Here we examined the role of annual water temperature variability in determining when and where walleye pollock (Theragra chalcogramma) spawn in the eastern...
Maritime spatial planning and fishery management are likely to generate extra costs for the fisheries by constraining fishermen activity with conservation areas and new utilizations of the sea such as offshore windmill parks. Growing concerns for greener and energy efficient fisheries are also likely to alter existing fishing patterns already...
Certain ecological processes dominate others at particular scales, and the response of populations to exogenous and endogenous forces are typically scale dependent. In spite of this central role played by scale, the temporal and spatial scales of human impacts on ecosystems and populations remain almost unknown. We applied a multiscale...
With the ongoing crisis of biodiversity loss and limited resources for conservation, the concept of biodiversity hotspots has been useful in determining conservation priority areas. However, there has been limited research into how temporal variability in biodiversity may influence conservation area prioritization. To address this information gap, we present an...
Population growth is affected by several factors such as climate, species interaction
and harvesting pressure. However, additional complexity can arise if fishing increases the sensitivity
to environmental variability. To predict the effects of fisheries and climate on marine populations,
there is a need for improved understanding of how they affect...
North Pacific albacore (Thunnus alalunga) is a highly migratory and
commercially valuable species of tuna. All stock assessments and management
decisions for North Pacific albacore are presently based on the assumption of a single,
uniform stock. However, a growing body of evidence from diverse sources suggests
that there are two...
