Freshwater ecosystems are among the most endangered on Earth and vulnerable to climate change. Studies have shown that change has already altered phenology distribution of freshwater species. However, there still major gaps in our understanding potential impacts their organisms. fishes were used as effective indicators for identifying degree, direction scale changes aquatic ecosystem quality health. they rarely determine sensitive using species modeling. We modeled current future 15 endemic fish Iran identify winners losers high priority rivers conservation under In addition, we assessed elevational Our results showed five will lose some parts suitable range while ten gain new habitats. Considering restricted range, special concern, so this study can be fishes. Species which identified negatively affected by should prioritized monitoring subject programs. Using reductions size predicted, 20 targets actions reduce negative fish.

Abstract Climate change may lead to range shifts, and barriers such displacements result in extirpations from previously suitable habitats. This be particularly important freshwater ecosystems that are highly fragmented by anthropogenic obstacles, as dams other smaller in‐stream barriers. Conservation planning freshwaters should consider the dynamic effects of climate ability species cope with it. In this study, we developed a framework for incorporating climate‐driven dispersal into conservation taking account medium long‐term impacts obligatory interactions. Given mussels (Bivalvia: Unionida) group threatened organisms dependent on fish hosts complete their larval development dispersal, used Marxan prioritize areas joint Iberian Peninsula case study. We tested two connectivity scenarios between current future habitats, (i) unlimited capacity (ii) constrained artificial barriers, also identified priority translocation were unable disperse. Accounting distributions allowed identification areas, but disregarding unrealistic solutions. Integrating location more likely colonized following climatic although resulted an additional loss six eight features (~5%–7%) compared solutions without constraints.

Where removal is unfeasible, translocations additionally cover up do not meet targets due study highlights challenge identifying protected safeguard biodiversity under change.

Surface‐water dynamics and land use influence landscape connectivity across a major dryland region

Abstract Landscape connectivity is important for the long‐term persistence of species inhabiting dryland freshwater ecosystems, with spatiotemporal surface‐water dynamics (e.g., flooding) maintaining by both creating temporary habitats and providing transient opportunities dispersal. Improving our understanding how landscape varies respect to land use an step biodiversity in dynamic environments. Using a newly available validated Landsat TM ETM + time series, we modelled between within Australia's 1 million km 2 semiarid Murray Darling Basin across 25‐yr period (1987–2011). We identified key that serve as well‐connected “hubs,” or “stepping‐stones” allow long‐distance movements through habitat networks. compared distributions these short‐ dispersal during dry, average, wet seasons, land‐use types. The distribution stepping‐stones hubs varied spatially temporally, temporal changes driven drought flooding dynamics. Conservation areas natural environments contained higher than expected proportions throughout series; however, highly modified agricultural landscapes increased importance seasons. Irrigated particularly high dispersers, but remained relatively disconnected less vagile organisms. study may ideal high‐priority targets specific management aimed at improving habitats, potentially benefits beyond immediate site scale. Our results also highlight accounting influence spatial when studying variable
