“…Bats -Riparian zones provide numerous benefits for insectivorous bats, including favorable open habitats in the middle of a wooded area, water availability, and emergent aquatic insects as food resource [53,57,[64][65][66][67][68][69]. Yoshikura et al (2011) found that species richness and total abundance of two tree-roosting specialists (Myotis ikonnikovi, Murina ussuriensis) and the Japanese largefooted bat (M. macrodactylus) were significantly higher in riparian habitats than those in non-riparian habitats [70].…”

Riparian zone provides a variety of resources to organisms, including availability of water and subsidies. Water availability in riparian areas influences species distribution and trophic interaction of terrestrial food webs. Cross-ecosystem subsidies as resource flux of additional energy, nutrients, and materials benefit riparian populations and communities (e.g. plants, spiders, lizards, birds and mammals). However, aquatic ecosystems and riparian zones are prone to anthropogenic disturbances, which change water availability and affect the flux dynamics of cross-system subsidies. Yet, we still lack sufficient empirical studies assessing impacts of disturbances of land use, climate change and invasive species individually and interactively on aquatic and riparian ecosystems through influencing subsidy resource availability. In filling this knowledge gap, we can make more effective efforts to protect and conserve riparian habitats and biodiversity, and maintain riparian ecosystem functioning and services.

“…The expanded distribution is probably linked to human settlements and in particular to artificial bodies of water since non-desert species of bats must drink on a daily basis and drink more frequently compared with desert-dwelling bats (Razgour 2010). Kuhl's pipistrelle competes for the use of pools for drinking and foraging, resulting in temporal and spatial partitioning between local desert bat species (Razgour et al 2011). The documented competition between Kuhl's pipistrelle and desert-dwelling bat species (Polak et al 2011;Razgour et al 2011), combined with the increasing development of bodies of open water in the Negev and other drylands, may lead to further resource competition resulting in loss to the region's biodiversity.…”

Natural bodies of open water in desert landscapes, such as springs and ephemeral pools, and the plant-life they support, are important resources for the survival of animals in hyper arid, arid and semi-arid (dryland) environments. Human-made artificial water sources, i.e. waste-water treatment ponds, catchments and reservoirs, have become equally important for wildlife in those areas. Bodies of open water are used by bats either for drinking and/or as sites over which to forage for aquatic emergent insects. Due to the scarcity of available water for replenishing water losses during roosting and flight, open bodies of water of many shapes and sizes may well be a key resource influencing the survival,

“…However, many studies to date on bat habitat use within agricultural landscapes demonstrate that bats prefer remaining woodland, corridor and riparian habitats and avoid arable and agricultural lands (e.g. Walsh and Harris, 1996;Vaughan et al, 1997;Razgour et al, 2011). Studies also indicate that the abundance, diversity and activity of bats decline in parallel with the intensity of agricultural development (Russo and Jones, 2003;Wickramasinghe et al, 2003).…”

“…Specifically, agricultural and human developments have the greatest impacts on bats with lower wing-loading and more specialized habitat requirements. Woodland and riparian species are most affected (Walsh and Harris, 1996;Wickramasinghe et al, 2004;Duchamp and Swihart, 2008;Razgour et al, 2011), whereas more generalist species with typically higher wing-loading appear to be less at risk from anthropogenic impacts, including agricultural intensification (Duchamp and Swihart, 2008). Species with higher wing-loading typically forage in uncluttered habitats above canopy and exploit a higher diversity of insect prey than species with lower wing-loading.…”

a b s t r a c tThe conversion of natural lands to agriculture is a leading cause of the worldwide loss of biodiversity. In particular, cropland monocultures alter insect abundance and diversity compared to adjacent natural habitats. While agricultural lands can provide large numbers of insect pests as prey items to predators such as bats, insect pest population size vary greatly throughout growing seasons. This study assesses the importance of land use and corn earworm moth availability as spatial and temporal drivers of bat activity. We quantified spatial variation in land use patterns at fifteen sites located within the Winter Garden region in south central Texas and used bat detectors and insect pheromone traps to monitor nightly bat activity and corn earworm moth abundance across the landscape and throughout most of the year. Our temporal analyses show that bat activity was positively correlated with moth abundance, but only early in the growing season when moth abundance is at its peak. The key result from this study is a positive relationship between bat activity and natural habitat cover during late summer months, corresponding to periods of low moth abundance and a peak in bat activity. During the late summer period, bats were more active at sites containing a larger percentage of natural habitats than those containing a larger percentage of agricultural land. Our results strongly suggest that intensive agricultural practices create systems providing bats with inconsistent resource supply, but the persistence of natural habitats provides consistency in food supply though time. Taken together, these findings illustrate the importance of protecting and restoring natural habitats for the conservation for bats and the pest-suppression services they provide in agricultural ecosystems.
