“…Alternatively, these invasive species, once established, could respond to natural flows in a manner similar to native species. Hydrology and fish communities have been altered worldwide by major and ongoing anthropogenic perturbations (e.g., Deacon et al 2007). The magnitude of change observed in these Kansas streams, and elsewhere, probably is the result of the combined effects of a series of perturbations.…”

“…Globally, the need for restoration and mitigation of future impacts increases as streamflow regimes continue to be altered by dams (Nilsson et al 2005, Poff et al 2007), land use (Hascic andWu 2006, Scott 2006), and water withdrawals (Hauer and Lorang 2004, Nilsson et al 2005, Deacon et al 2007). Using retrospective analysis to link mechanisms directly to changes is difficult, but improving our ability to use historical data might help us evaluate the impact of changes caused by human alteration on the functioning of aquatic ecosystems and project future changes to these systems.…”

“…We identiWed hot spots of known occurrences of imperiled species, and determined whether these hot spots overlap with existing reserves. Following methodology outlined in Chaplin et al (2000), we divided Nevada into equal area hexagons as our analytical unit, ensuring comparison of equally sized areas. We chose to use hexagons that are 5 km on a side for a total of 64.9 km 2 .…”

To assess whether imperiled species are covered by existing protections in the biologically-rich state of Nevada, U.S.A., we compared the distribution of reserves with known imperiled species occurrences. For species poorly represented in reserves, we determined whether they were receiving alternate protection under the U.S. Endangered Species Act or voluntary conservation plans. A majority (212, 55%) of Nevada's 384 imperiled species had fewer than 25% of occurrences in reserves and most (282, 68%) had fewer than 50% of occurrences in reserves. Of imperiled species with less than 25% or fewer than two occurrences in reserves, only 9% are currently receiving alternate protection from the Endangered Species Act or voluntary plans. These results suggest that providing protection for imperiled species in Nevada will require both an expansion of the existing reserve system, which currently covers 14% of the state, and protection of more species under the Endangered Species Act or other programs. By dividing Nevada into equal-sized hexagons and scoring each of these hexagons based on a rarity-weighted richness index of imperiled species occurrences, we identiWed 19 imperiled species hot spots in Nevada. No imperiled species occurrences were protected in seven (37%) and less than half were protected in 11 (58%) of these hot spots. Protecting these areas could provide important additional protection for imperiled species in Nevada. Evaluations of protective measures for biological diversity should include the full suite of protections, including both reserves and laws and regulations.

“…When the suitable habitats and their climatic refuges are degraded, the existence of endemic taxa becomes threatened (e.g., [55]). Since the 20th century, intensive alterations of hydrology have been closely related with the massive constructions of reservoirs and dams, as well as the disappearance of streams and springs, due to human actions [56].…”

Abstract:This study aimed to identify the biogeographical and environmental factors affecting the biodiversity of endemic aquatic species (i.e., Ephemeroptera, Plecoptera and Trichoptera; EPT). We used data collected from 714 sampling sites combined with 39 environmental factors. Ten EPT endemic species were identified. The sampling sites grouped into four clusters based on the similarities of the endemic EPT assemblages using a hierarchical cluster analysis. Non-metric multidimensional scaling (NMS) revealed the differences among the four clusters, with the first three axes being strongly related to annual average, August, and January temperatures, as well as altitude. The random forest model identified geological and meteorological factors as the main factors influencing species distribution, even though the contributions of environmental factors were species-specific. Species with the lower occurrence frequency (i.e., Pteronarcys macra, Kamimuria coreana, and Psilotreta locumtenens) mainly occurred in the least-disturbed habitats. P. macra represents a priority conservation species, because it has a limited distribution range and is highly vulnerable to anthropogenic disturbance. Our results support the need for an environmental management policy to regulate deforestation and conserve biodiversity, including endemic species.
