“…Species are affected by climate change because these changes modify the environmental gradients that interact with them (Galbraith et al, 2010;Hastie et al, 2003;IPCC, 2014) with consequent shifts in phenology, range and physiology (reviewed in Bellard et al, 2012).…”

“…Freshwater invertebrates received much less attention but inside this group freshwater mussels are among the species frequently used in those studies or programs, because they play an important role in the ecosystem, with some species being classified as indicator or umbrella species, and are one of the most endangered groups of animals on the planet (Bogan, 2008;Galbraith et al, 2010;Geist, 2010;Howard and Cuffey, 2006;Lopes-Lima et al, 2014;Skinner et al, 2003;Sousa et al, 2013). Due to its large size, sedentary, long life span and variable sensitivity to environmental contaminants, freshwater bivalves can also be very useful as indicators of ecological integrity and as sentinels of environmental perturbation (Farris and Van Hassel, 2006).…”

• Develop a verification scheme to check stress on M. margaritifera based on thresholds • Assess the impact of future climate change in conservation status of M. margaritifera • Assess the impact of land-use in habitat requirements of M. margaritifera • Propose conservation measures to prevent extinction of M. margaritifera in Portugal a b s t r a c t a r t i c l e i n f o In this study, we assess the impacts of future climate and land-use in the Beça River (northern Portugal) under different scenarios and how this will translate into the conservation status of the endangered pearl mussel Margaritifera margaritifera (Linnaeus, 1758). This species is currently present in several stretches of the Beça River that still hold adequate ecological conditions. However, the species is threatened by projected declines in precipitation for the 21st century, with implication on the river flows and water depths that might decrease below the species requisites. This situation could be especially critical during summer conditions since the ecological flows may not be assured and several river stretches may be converted into stagnant isolated pools. The habitat connectivity will also be affected with reverberating effects on the mobility of Salmo trutta, the host of M. margaritifera, with consequences in the reproduction and recruitment of pearl mussels. In addition, humanrelated threats mostly associated with the presence of dams and an predicted increases in wildfires in the future. While the presence of dams may decrease even further the connectivity and river flow, with wildfires the major threat will be related to the wash out of burned areas during storms, eventually causing the disappearance of the mussels, especially the juveniles. In view of future climate and land-use change scenarios, conservation strategies are proposed, including the negotiation of ecological flows with the dam promoters, the replanting of riparian vegetation along the water course and the reintroduction of native tree species throughout the catchment.

“…Mussel data from Isely (1924) were collected in 1910-1911 prior to dam construction on these rivers, though only a few sites were sampled: 3 in the Kiamichi and 1 in the Little. Present-day sampling efforts have been much more extensive, as we present data from 7 sites in the Kiamichi River (Galbraith et al 2010) and 8 sites in the Little River. In total, 35 mussel species have been reported in these rivers, 31 from the Kiamichi River, and 33 from the Little River with 29 species common to both rivers (Table 1).…”

“…Spooner and Vaughn (2008) investigated the effects of naturally occurring temperatures (5-35°C) on the physiological condition of eight common mussel species in the southern US, and found that species are either thermally sensitive or tolerant based on their response to warm temperatures (35°C). While all mussel species are susceptible to mortality and stranding during droughts, thermally sensitive species are more likely to perish during high temperature and low-flow conditions (Galbraith et al 2010).…”

“…The Kiamichi and Little Rivers, located in the southern plains of the US, are similar in size and mussel species composition but were managed differently during a recent, multi-year drought (1998Galbraith et al 2010): in the Kiamichi River water releases into the river from a tributary impoundment decreased as the drought progressed, while in the Little River water releases into the river were maintained during the drought. We use longterm data from each river to compare mussel species richness and community structure before and after the drought and discuss how these results likely relate to water management practices.…”

Droughts often pose situations where stream water levels are lowest while human demand for water is highest. Here we present results of an observational study documenting changes in freshwater mussel communities in two southern US rivers during a multi-year drought. During a 13-year period water releases into the Kiamichi River from an impoundment were halted during droughts, while minimum releases from an impoundment were maintained in the Little River. The Kiamichi observed nearly twice as many low-flow events known to cause mussel mortality than the Little, and regression tree analyses suggest that this difference was influenced by reduced releases. During this period mussel communities in the Kiamichi declined in species richness and abundance, changes that were not observed in the Little. These results suggest that reduced releases during droughts likely led to mussel declines in one river, while maintaining reservoir releases may have sustained mussel populations in another.

This article reports a large‐scale die‐off of approximately one‐third of the unionid mussels inhabiting a shallow, naturally eutrophic, floodplain lake (Zalew Pińczowski), which took place within the space of just a few days. Mortality was the highest in Pseudanodonta complanata (81%), followed by Unio pictorum (58%), Anodonta cygnea (26%), Unio tumidus (15%), and Anodonta anatina (5%). It was significantly related to mussel size (age) only in A. cygnea, with the mortality rate higher in smaller (young) mussels. Pseudanodonta complanata was already the rarest species in the lake, and the number of survivors decreased to such an extent as to trigger a possible Allee effect. The most likely cause of the die‐off was a motor‐boating incident that had directly preceded the die‐off. Analysis of the water samples collected just after the die‐off revealed an extremely high concentration of phosphate (up to 0.5 mg dm−3) and nitrite (up to 0.06 mg dm−3). We suggest that the boat movements must have disturbed the lake sediments, thereby disrupting the mussels' physiology and causing mass mortality. The high sensitivity of P. complanata to environmental stress suggests that it may be an effective umbrella species for the protection of co‐occurring mussel species in eutrophic lakes.
