Distribution Pattern of Fish Richness in the Yarlung Zangbo River Basin

open access: yesDiversity, 2022
Global warming significantly affects plateau glaciers and surface runoff, and fish are bound to be severely affected. Additionally, an increasing number of human activities (e.g., free captive animals, aquaculture) have led to vulnerable plateau ...

Survival of the rare Packera layneae (Asteraceae), under chaparral and after fire

open access: yesCalifornia Fish and Wildlife Journal, 2020
Conservation of rare plants requires an understanding of how the species responds to natural and artificial disturbance dynamics. For chaparral species this includes the natural disturbances of fire and shrub canopy closure during the interfire period ...

An application of maximum entropy model to evaluate the differential effect of cage aquaculture on the distribution of a native and an endemic fish species in Lake Maninjau, Indonesia

open access: yesJournal of Freshwater Ecology, 2023
Physical cage aquaculture structure can attract native fish species in marine and freshwater ecosystems. Most studies on the effects of cage farms on native fish distribution have been undertaken in marine environments and outside of Asia as the main ...

Diets of Longnose Sucker in Yellowstone Lake, Yellowstone National Park, USA

open access: yesJournal of Freshwater Ecology, 2020
Invasive species introduction and expansion is the second greatest threat to global biodiversity decline after habitat degradation. Introduced in the 1930s, the benthivorous Longnose Sucker (Catostomus catostomus) became established in Yellowstone Lake ...

Yellowstone Lake Ecosystem Restoration: A Case Study for Invasive Fish Management

open access: yesFishes, 2020
Invasive predatory lake trout Salvelinus namaycush were discovered in Yellowstone Lake in 1994 and caused a precipitous decrease in abundance of native Yellowstone cutthroat trout Oncorhynchus clarkii bouvieri. Suppression efforts (primarily gillnetting)

Spatial and temporal variation of fish assemblage structure in a neotropical Mexican river

open access: yesRevista Mexicana de Biodiversidad, 2021
The introduction of non-native fish into the Teuchitlán River, in west-central Mexico, was suggested as a key factor behind the change in the fish assemblage, and even in the extinction of endemic species. The characterization of the fish assemblage and

Role of Impoundments Created by Low-Head Dams in Affecting Fish Assemblages in Subtropical Headwater Streams in China

open access: yesFrontiers in Ecology and Evolution, 2022
Low-head dams are ubiquitous human disturbances that degrade aquatic ecosystem function worldwide. The localized effects of low-head dams have been relatively well documented; however, most previous studies have ignored the concealed process caused by ...

Parasitic Helminths and Freshwater Fish Introduction in Europe: A Systematic Review of Dynamic Interactions

open access: yesFishes, 2023
The introduction of non-native freshwater fish is a primary cause of aquatic biodiversity loss at global scale. Such introductions have a severe impact on freshwater ecosystems in terms of competition, predation, habitat alteration, genetic pollution and
