Pacific pink salmon (Oncorhynchus gorbuscha) invasions, thought to originate from populations introduced and established in Russia, occurred along the Norwegian coast in 2017 and 2019. Despite several thousand pink salmon entering and establishing in northern Norwegian rivers, current understanding of the ecological effect of the species in northern Europe is limited. Scavengers feeding on Aquatic Invasions is an open access, peer-reviewed international journal focusing on academic research of biological invasions in inland and coastal water ecosystems from around the world. Aquatic Invasions is an official journal of International Association for Open Knowledge on Invasive Alien Species (INVASIVESNET) .

Transitions in habitats and feeding behaviors were fundamental to the diversification of life on Earth. There is ongoing debate regarding the typical directionality of transitions between aquatic and terrestrial habitats and the mechanisms responsible for the preponderance of terrestrial to aquatic transitions.

Aquatic communities appear to be Keywords: Alternanthera philoxeroides Biological invasions Biotic resistance Environmental heterogeneity Species diversity Agencies spent 57% more funds managing aquatic plants than terrestrial plants (Figure 2) with the bulk of annual spending allocated to only five species, including the aquatic plant hydrilla ($9.7 ± 1.3M) and the terrestrial tree Melaleuca quinquenervia ($3.6 ± 0.4M). terrestrial sister taxa. We use this systematic analysis to determine the number of different amphibious species, whether they repre sent a single invasion of the water that then diversified or multiple independent invasions, and finally a molecular clock to estimate how long ago these aquatic shifts could have occurred.

Terrestrial and Aquatic Wildlife Species of Management Concern in the City of Portland matrix was developed to provide basic background on each species. A total of 78 individuals representing 41 organizations were invited to participate in an 18-questions online survey via email notification.

2015), and the metabolic activity and biological diversity of headwater streams are linked to the functioning of larger rivers and water bodies (Vannote et al. 1980, Tank et al. 2010). The often under-appreciated frequency of vertebrates’ terrestrial invasions begs the question of why the particular group of sarcopterygian fishes that moved out of the shallow waters of the Paleozoic and onto land ultimately gave rise to a prolific radiation of diverse terrestrial species—while other invasions by vertebrates have not.

Carbon Dioxide (CO 2) Fluxes From Terrestrial and Aquatic Environments in a High‐Altitude Tropical Catchment Chloe L. Schneider Department of Geography, University of North Carolina at Chapel Hill, Chapel Hill, NC, USA However, for semi‐aquatic and terrestrial animals, the application of this technique remains relatively untested. We first assess the efficiency of eDNA metabarcoding in detecting semi‐aquatic and terrestrial mammals in natural lotic ecosystems in the UK by comparing sequence data recovered from water and sediment samples to the mammalian communities expected from historical data. Semi-Aquatic Turtles. These are turtles that live in both land and water.
