Landscape Modeling of Threespine Stickleback Occurrence in Small Southeast Alaska Lakes
Although threespine stickleback (Gasterosteus aculeatus L.) are known to inhabit a wide range of habitats, their distribution in lakes across Southeast Alaska is not known. Threespine stickleback are an important prey item for many consumers in freshwater ecosystems. Additionally, isolated populations may be genetically unique and thus important from a conservation perspective. This study focus...
متن کاملGlobal climate change and potential effects on Pacific salmonids in freshwater ecosystems of southeast Alaska
General circulation models predict increases in air temperatures from 1°C to SoC as atmospheric CO2 continues to rise during the next 100 years. Thermal regimes in freshwater ecosystems will change as air temperatures increase regionally. As air temperatures increase, the distribution and intensity of precipitation will change which will in turn alter freshwater hydrology. Low elevation floodpl...
متن کاملCorrection: Climate Change Sensitivity Index for Pacific Salmon Habitat in Southeast Alaska
Global climate change may become one of the most pressing challenges to Pacific Salmon conservation and management for southeast Alaska in the 21st Century. Predicted hydrologic change associated with climate change will likely challenge the ability of specific stocks to adapt to new flow regimes and resulting shifts in spawning and rearing habitats. Current research suggests egg-to-fry surviva...
متن کاملPhylogeography of endemic ermine (Mustela erminea) in southeast Alaska.
The North Pacific Coast (NPC) of North America is a region of high mammalian endemism, possibly due to its highly fragmented landscape and complex glacial history. For example, four island and one mainland subspecies of ermine, Mustela erminea, have been described as endemic to southeast Alaska alone. To better understand the role of past climatic change in generating diversity in the region, w...
متن کاملRegulation of Bald Eagle Reproductive Rates in Southeast Alaska
I examined the influence of food abundance and habitat quality on reproduction of Bald Eagles (Haliaeetus leucocephalus) in the Chilkat Valley, Alaska. The proportion of active nests was greatest and the timing of laying earliest in portions of the study area where food was most abundant. Clutch size was not related to food availability. Offspring survival was higher in breeding areas where foo...
