Effective management for wide-ranging species must be conducted over vast spatial extents, such as whole watersheds and regions. Managers and decision makers must often consider results of multiple quantitative and qualitative models in developing these large-scale multispecies management strategies. We present a scenario-based decision support system to evaluate watershed-scale management plans for multiple species of Pacific salmon in the Lewis River watershed in southwestern Washington, USA. We identified six aquatic restoration management strategies either described in the literature or in common use for watershed recovery planning. For each of the six strategies, actions were identified and their effect on the landscape was estimated. In this way, we...

Present and Future Potential Habitat Distribution of Carcharhinus falciformis and Canthidermis maculata By-Catch Species in the Tropical Tuna Purse-Seine Fishery under Climate Change ArchiMer
Lezama-ochoa, Nerea; Murua, Hilario; Chust, Guillem; Van Loon, Emiel; Ruiz, Jon; Hall, Martin; Chavance, Pierre; De Moline, Alicia Delgado; Villarino, Ernesto.
By-catch species from tropical tuna purse seine fishery have been affected by fishery pressures since the last century; however, the habitat distribution and the climate change impacts on these species are poorly known. With the objective of predicting the potential suitable habitat for a shark (Carcharhinus falciformis) and a teleost (Canthidermis maculata) in the Indian, Atlantic and Eastern Pacific Oceans, a MaxEnt species distribution model (SDM) was developed using data collected by observers in tuna purse seiners. The relative percentage of contribution of some environmental variables (depth, sea surface temperature, salinity and primary production) and the potential impact of climate change on species habitat by the end of the century under the A2...

Growth, feeding and distribution of the solenette Buglossidium luteum with particular reference to its habitat preference ArchiMer
Amara, Rachid; Mahe, K; Le Pape, Olivier; Desroy, N.
Growth, condition, diet and spatial distribution of the solenette Buglossidium luteum (Risso, 1810) were investigated along the coasts of the French Atlantic, eastern English Channel and Southern Bight of the North Sea. Distribution and habitat preferences of solenette were analysed in relation to physical and biological features presumed to influence fish distribution. B. luteum was patchily distributed and concentrated in shallow muddy and muddy-sand bottoms moderately influenced by estuarine waters (euhaline waters). In the studied area, solenette seemed to find habitats suitable for growth. Food availability was not assumed to be a limiting factor for solenette distribution in contrast to abiotic factors such as salinity.

Genetic Population Structure and Allele Surfing During Range Expansion in Dynamic Habitats Anais da ABC (AABC)
BRAGA,ROSANA T.; RODRIGUES,JOÃO F.M.; DINIZ-FILHO,JOSÉ A.F.; RANGEL,THIAGO F..
Abstract: Expanding populations may loss genetic diversity because sequential founder events throughout a wave of demographic expansion may cause “allele surfing”, as the alleles of founder individuals may propagate rapidly through space. The spatial components of allele surfing have been studied by geneticists, but have never been investigate on dynamic and shifting habitats. Here we used an individual-based-model (IBM) to study how interactions between different habitat restoration scenarios and biological characteristics (dispersal capacity) affect the spatial patterns of the genetic structure of a population during demographic expansion. We found that both habitat dynamics and dispersal capacity, as well as their interaction, were the drivers of...
