“…There were no other landscape effects on total bee richness or abundance. Such a positive correlation with wetland cover has also been found in communities of insects (Scriven et al ., ), such as bees (Buschini, ; Stewart et al ., ), butterflies (Clausen et al ., ) and syrphids (Stewart et al ., ). The strong positive effect of wetlands on total bee abundance, however, did not appear to be a general pattern for the whole community.…”

1 Global population declines of insect pollinators highlight the need for a greater ecological understanding of the responses of wild pollinators to local management actions and to human alterations of landscapes, especially in the tropics where crops are highly dependent on wild pollinators. 2 We examined the effects of local and landscape factors on the richness and abundance of bees in farms around Bangkok, Thailand. Bee communities in 24 mango (Mangifera indica L.) orchards in heavily modified landscapes (61-99% anthropogenic land cover) were compared. We predicted that bees would be more species rich in orchards with higher flower diversity, whereas small-sized bees with non-eusocial and/or below-ground nesting habits would be more sensitive to human disturbance, and hence rare. 3 Twenty-eight species were caught and individuals of genus Apis comprised >92% of 3842 bees sampled and dominated all 24 sites. 4 Habitat effects on bee richness and abundance were stronger at the farm scale than at the landscape scale. At the farm scale, total bee richness and abundance, as well as small, non-eusocial and below-ground nesting bee richness and abundance, were negatively associated with field size and positively associated with flowering plant diversity. The percentage of urban land cover within a 1-km radius was weakly but positively related to total bee richness and small-sized bee richness; total bee abundance was positively associated with wetland cover. 5 A greater diversity of flowering plants retained in smaller fields maintained higher bee richness and abundances, particularly small-sized bees. Farmers can enhance bee populations by maintaining small patches of flowers in their fields.

“…Furthermore, and since emerging adult stages are typical prey of several riparian carnivores, studying how water conditions affect adult stages of these invertebrates also allows understanding how the effects of environmental perturbations propagate between adjacent habitats that traditionally have been considered functionally apart from each other, such as river and terrestrial systems. This represents a topic of increasing interest [49][50][51][52].…”

Geographical origin determines responses to salinity of Mediterranean caddisflies

Many freshwater ecosystems worldwide, and particularly Mediterranean ones, show increasing levels of salinity. These changes in water conditions could affect abundance and distribution of inhabiting species as well as the provision of ecosystem services. In this study we conduct laboratory experiments using the macroinvertebrate Smicridea annulicornis as a model organism. Our factorial experiments were designed to evaluate the effects of geographical origin of organisms and salinity levels on survival and behavioral responses of caddisflies. The experimental organisms were captured from rivers belonging to three hydrological basins along a 450 Km latitudinal gradient in the Mediterranean region of Chile. Animals were exposed to three conductivity levels, from 180 to 1400 μS/cm, close to the historical averages of the source rivers. We measured the behavioral responses to experimental stimuli and the survival time. Our results showed that geographical origin shaped the behavioral and survival responses to salinity. In particular, survival and activity decreased more strongly with increasing salinity in organisms coming from more dilute waters. This suggests local adaptation to be determinant for salinity responses in this benthic invertebrate species. In the current scenario of fast temporal and spatial changes in water levels and salt concentration, the conservation of geographic intra-specific variation of aquatic species is crucial for lowering the risk of salinity-driven biodiversity loss.

“…This study aids to expand our knowledge about how the organisms respond to 212 environmental variation, specifically to salinity, and which is the role of the historical 213 context in shaping phenotypic responses to ecological conditions. In particular, we 214 showed that organisms from different geographic locations responded deferentially to This represents a topic of increasing interest [42][43][44][45].…”

“…Nevertheless, due to our limited understanding 41 of the ecological consequences of osmotic stress, it is unclear how the phenotypic 42 responses to different salinity levels are shaped by local adaptation. 43 In this study we evaluate experimentally the effects of geographical origin and local 44 salinity levels on survival and behavioral responses of a model benthic freshwater species 45 inhabiting the Mediterranean region of Chile, the caddisfly Smicridea annulicornis. Our 46 general prediction is that survival and behavioral responses to different salinity levels 47 will be function of the geographical origin of the organisms.…”
