Fish species introductions provide novel insights into the patterns and drivers of phylogenetic structure in freshwaters.
Despite long-standing interest of terrestrial ecologists, freshwater ecosystems are a fertile, yet unappreciated, testing ground for applying community phylogenetics to uncover mechanisms of species assembly. We quantify phylogenetic clustering and overdispersion of native and non-native fishes of a large river basin in the American Southwest to test for the mechanisms (environmental filtering ...
متن کاملFish extinctions alter nutrient recycling in tropical freshwaters.
There is increasing evidence that species extinctions jeopardize the functioning of ecosystems. Overfishing and other human influences are reducing the diversity and abundance of fish worldwide, but the ecosystem-level consequences of these changes have not been assessed quantitatively. Recycling of nutrients is one important ecosystem process that is directly influenced by fish. Fish species v...
متن کاملRestricted-Range Fishes and the Conservation of Brazilian Freshwaters
BACKGROUND Freshwaters are the most threatened ecosystems on earth. Although recent assessments provide data on global priority regions for freshwater conservation, local scale priorities remain unknown. Refining the scale of global biodiversity assessments (both at terrestrial and freshwater realms) and translating these into conservation priorities on the ground remains a major challenge to b...
متن کاملDrivers of Organizational Participation in XML-based Industry Standardization Efforts
XML-based vertical standards are an emerging compatibility standard for describing business processes and data formats in specific industries that have emerged in the past decade. Vertical standards, typically implemented using eXtensible Markup Language (XML), are incomplete products in constant evolution, continually adding functionality to reflect changing business needs. Vertical standards ...
متن کاملCatch per unit efforts and impacts of gears on fish abundance in an oxbow lake ecosystem in Eastern India
Background: Oxbow lakes are abundant in indigenous fishes, but they are subject to unsustainable fishing practices, potential overexploitation, and indiscriminate use of fine-meshed fishing gear. To quantify the catch per unit effort (CPUE) and impact of fishing gears on fish abundance, a survey was carried out in an oxbow lake in eastern India. Methods: The gear-wise CPUE for fish caught in...
