1 Rhododendron ponticum is a serious invasive alien plant in the British Isles and is of 2 significant conservation and economic concern. Here, we integrate information on both the 3 life-history and spatial dynamics of this species within an individual-based, spatially-explicit 4 model and investigate the effectiveness of different control strategies. Importantly, we 5 simulate seed movement a...

Warming air temperatures in the Arctic are modifying the rates of thermokarst processes along Alaska’s Arctic Coastal Plain. The Arctic Coastal Plain is dominated by thaw lakes. These kilometer-scale lakes are the most visible surface features in the region, and they provide important habitats for migratory birds. The lakes are formed by thermokarst processes, and are therefore susceptible to c...

Abstract Recent efforts in ocean mapping of seafloor habitat have made data increasingly available. For bottom-dwelling and/or sessile species, there is often a strong relationship between population productivity and habitat, stock assessment models are likely to be improved by the inclusion habitat. Here, we extend recently developed spatio-temporal biomass dynamics model allow inform probabil...

The behavior of long-distance migrants during stopover is constrained by the need to quickly and safely replenish energetic reserves. Replenishing fuel stores at stopover sites requires adjusting to unfamiliar landscapes with little to no information about the distribution of resources. Despite their critical importance to the success of songbird migration, the effects of landscape composition ...

background: scorpions’ stings and their own mortalities place them among the most important health and medical problems. the dreadful features and especially their poisonous stings are considered a major cause of human stress and abhorrence/phobia. the current study aimed to study the scorpion fauna of ilam province, south western iran in order to manage scorpionism related problems. methods: i...

The effects of habitat fragmentation and their implications for biodiversity is a central issue in conservation biology which still lacks an overall comprehension. There is not yet a clear consensus on how to quantify fragmentation even though it is quite common to couple the effects of habitat loss with habitat fragmentation on biodiversity. Here we address the spatial patterns of species dist...

Land use is rapidly expanding in the Greater Yellowstone Ecosystem, primarily from growth in the number of rural homes. There is a need to project possible future land use and assess impacts on nature reserves as a guide to future management. We assessed the potential biodiversity impacts of alternative future land use scenarios in the Greater Yellowstone Ecosystem. An existing regression-based...

The import of resources (food, nutrients) sustains biological production and food webs in resource-limited habitats. Resource export from donor habitats subsidizes production in recipient habitats, but the ecosystem-scale consequences of resource translocation are generally unknown. Here, I use a nutrient-phytoplankton-zooplankton model to show how dispersive connectivity between a shallow auto...
