“…Many of these datasets have been used to relate inter-annual community-changes to climate change, highlighting that the frequency of dry years has increased in more recent years and that communities have changed accordingly. For example, Sáinz-Bariáin et al [82] found an increase in Trichoptera richness in high-altitude, mountain Mediterranean rivers after a 20-year period, whereas Pace et al [81] found that riffle species shifted to lentic species during a 14-year period in two Mediterranean streams with different hydrological characteristics. These patterns follow the hydrological changes experienced in these areas that may be the result of a changing climate.…”

Abstract:Variability in flow as a result of seasonal precipitation patterns is a defining element of streams and rivers in Mediterranean-climate regions of the world and strongly influences the biota of these unique systems. Mediterranean-climate areas include the Mediterranean Basin and parts of Australia, California, Chile, and South Africa. Mediterranean streams and rivers can experience wet winters and consequent floods to severe droughts, when intermittency in otherwise perennial systems can occur. Inter-annual variation in precipitation can include multi-year droughts or consecutive wet years. Spatial variation in patterns of precipitation (rain vs. snow) combined with topographic variability lead to spatial variability in hydrologic patterns that influence populations and communities. Mediterranean streams and rivers are global biodiversity hotspots and are particularly vulnerable to human impacts. Biomonitoring, conservation efforts, and management responses to climate change require approaches that account for spatial and temporal variability (including both intra-and inter-annual). The importance of long-term data sets for understanding and managing these systems highlights the need for sustained and coordinated research efforts in Mediterranean-climate streams and rivers.

“…We studied species diversity and size‐related trait variability within and among sites of multispecies stonefly assemblages (henceforth referred to as communities), located along an elevational gradient in the Mediterranean high mountain range Sierra Nevada (Spain). In high altitude Mediterranean streams, the cool‐water adapted species are especially vulnerable to climate change through habitat loss or replacement by temperature‐generalist species (Domisch, Jähnig, & Haase, ), as previously found in Sierra Nevada (Finn, Zamora‐Muñoz, Múrria, Sáinz‐Bariáin, & Alba‐Tercedor, ; Sáinz‐Bariáin et al., ).…”

“…In Sierra Nevada, other strategies facing climate change are found for freshwater invertebrates. For instance species richness of Trichoptera increased in altitude during a 20‐year period by the colonisation of headwaters reaches from mid‐lowland stream sections (Sáinz‐Bariáin et al., ), which evidences lineage‐specific strategies in response to climate change as caddisflies are, in general, more dispersive than stoneflies.…”

Seasonality, species richness and poor dispersion mediate intraspecific trait variability in stonefly community responses along an elevational gradient

Summary Across environmental gradients, some functional strategies are favoured over others resulting in differences in local species composition and distribution of any given functional trait. This generates among‐Species Trait Variability (STV) across the gradient (reflecting species turnover), as well as spatial Intraspecific Trait Variability (ITV), which together contribute to Community Trait Variability (CTV). Understanding functional trait responses of freshwater biota is critical for elucidating the mechanisms that operate during community assembly and addressing community level responses to climate warming. In freshwater insects, temperature and ecological conditions regulate growth rates. Here, we examined size‐related trait variability components of short‐dispersing stoneflies (Insecta: Plecoptera) within and among multispecies stonefly assemblages (henceforth referred to as communities), located along an elevational gradient in Sierra Nevada (Spain) to assess the components of trait‐elevation matching (STV, ITV, CTV). Relative to downstream reaches, headwaters hypothetically show greater internal physical habitat heterogeneity (large exposed rocks, tree roots, woody debris) and greater local species richness of cool‐water adapted stoneflies. As a result, we expected CTV to increase with elevation, with a higher contribution of STV than ITV in upper reaches due to higher species richness and trait divergence among them. In contrast, the pattern of ITV should vary depending on whether the main driver across elevation is species richness (decrease due to niche partitioning) or ecological conditions (increase associated to physical habitat heterogeneity). Eleven streams were sampled every 2 weeks over 1 year and five size‐related traits were measured on 6,893 individuals belonging to 16 species. Overall, STV made a much larger contribution to CTV than ITV, which only became an important contributor in species‐poor assemblages, especially in winter and autumn. Within each season, the trait‐elevation matching was weak. Functional species‐specific responses to the elevational gradient most often did not mirror the response of the entire communities, since highly variable (and even opposed or discontinuous) contributions to ITV were found across species. Overall, ITV contributed little to trait‐elevation matching, which suggests high vulnerability of short‐dispersing stoneflies to habitat shifting associated to future climate warming due to limited phenotypic plasticity. Moreover, varying functional trait patterns across species emphasise species‐specific responses to climate change as opposed to a unique whole community response. However, further trait‐based macroecological studies across freshwater macroinvertebrates lineages are needed to compare patterns and establish generalisations.

“…Macroinvertebrate community of the upper reaches of rivers currently hosts more species diversity than 30 years ago (Sáinz‐Bariáin et al. ). For terrestrial ecosystems, similar patterns have been found, with significant changes in the spatial distribution and/or abundance of some groups of vertebrates (Zamora and Barea‐Azcón ) as well as certain invertebrates, such as dung beetles (Menéndez et al.…”
