“…Modelling the distribution of species throughout multiple seasons at a continental or global scale can help reveal important patterns of seasonal habitat preferences at a scale more relevant to animal migration (Fink et al, ). Many studies assess the relationship between species occurrences and climatic variables to predict potential distribution across the landscape (Abolmaali, Tarkesh, & Bashari, ; Bosso et al, ; Thapa et al, ), but the specialized diets of nectarivorous bats may render food plants more biologically relevant to their distribution (Arita & Santos‐del‐Prado, ). Hence, we used the distribution of plants that have been documented in the diet of these bats as explanatory variables, in addition to more commonly used bioclimatic, topographic and land cover variables, to generate SDMs of C. mexicana , L. nivalis and L. yerbabuenae .…”

Aim:The Mexican long-tongued bat (Choeronycteris mexicana), Mexican long-nosed bat (Leptonycteris nivalis) and lesser long-nosed bat (Leptonycteris yerbabuenae) (Phyllostomidae: Glossophaginae) undertake long-distance migrations from southcentral Mexico to the south-western United States. It is proposed that these bats migrate along a nectar corridor of columnar cacti and Agave species, but this has not been tested with independent data and the spatiotemporal nature of this relationship is poorly understood. Our goal was to test this nectar corridor hypothesis and determine the relative importance of food plant and abiotic variables to the distribution and seasonal movements of these migratory nectarivores.Location: Mexico and the south-western United States. Methods:We generated species distribution models (SDMs) of documented food plants for these bats. We then created SDMs for each bat following a model selection approach, using food plant and abiotic predictor variables. We modelled migration pathways for C. mexicana and L. yerbabuenae using circuit theory and seasonal SDMs based on seasonally available food plants. Main conclusions: Food plants were more important than climatic and topographic variables in shaping the distribution of these bats. The most important predictors of distribution were Agave, columnar cacti and species richness of food plants. Species richness of food plants was the most consistently important variable, but the components of this diversity varied by bat species: Choeronycteris mexicana was influenced by Agave and cacti; Leptonycteris nivalis was influenced solely by Agave; Leptonycteris yerbabuenae was influenced more generally by cacti, Agave and C3 plants. Migration models for C. mexicana and L. yerbabuenae provided independent support for the nectar corridor hypothesis and indicate shifts in relative importance of specific food plants throughout the year. These results suggest that conservation of these bats should focus more broadly on management for species richness of food plants, especially in tropical dry forests.

“…Extraction of natural ecosystems has brought considerable net benefits to human beings and socioeconomic development, but it has also caused a great loss of ecosystem services (ES) [9,10]. Land-use changes are the most direct manifestations of the interaction between humans and natural ecosystems [11][12][13][14]. Previous studies have indicated that land-use changes caused by both natural and anthropogenic factors have greatly affected the delivery of crucial ES, such as gas regulation, soil conservation, and biodiversity maintenance [15][16][17][18].…”

Converting natural ecosystems to cultivated land, driven by human activities, has been considered a significant driver of limiting the delivery of ecosystem services (ES). The ES loss in the past was mainly caused by agricultural activities that have been taken to meet people’s needs in Northeast China. Quantifying historical declining ecosystem service values is essential to facilitate sustainable development. In this study, remote sensing images were used to investigate the history of cultivated land expansion over the last five decades. Additionally, ES variations caused by agricultural expansion since 1965 were quantified in the Small Sanjiang Plain (SSP), Northeast China. From the results, cultivated land expanded from 3.97% of the total SSP area to 66.40% from 1965 to 2015 (approximately 898.23 million ha), of which paddy field expanded drastically from 0% to 55.93%. Variations in cultivated land resulted in a loss of ecosystem service values by 11,893.85 million dollars, of which 62.98 million dollars were caused by the internal conversion between cultivation during 1965–2015. Agricultural expansion accelerated the export of agricultural products function, while it decreased almost all other functions, especially hydrological regulation and freshwater supply function. For future sustainability of the SSP, some suggestions, such as restoring natural ecosystems, planting trees between cultivated land, coculture systems, and winter-flooding of paddy rice were provided in our study.

“…Although recent estimates of positive population trends in European bat populations have led to some optimism (Van der Meij et al, 2015), the situation of many bat species is still of concern, and, at the national scale, bats are still on the decline in several EU countries. European bat species are threatened by several factors, including roost loss (Mitchell-Jones et al, 2007;Marnell and Presetnik, 2010;Stone et al, 2015a;Voigt et al, 2016), alteration or disappearance of foraging habitat (Racey and Entwistle, 2003), agricultural intensification including pesticide use (Stahlschmidt and Br € uhl, 2012;Park, 2015;Stahlschmidt et al, 2017), intensive forestry (Russo et al, 2016a), large-scale wildfires (Bosso et al, 2018), light pollution (Stone et al, 2015b), alien species (Welch and Leppanen, 2017) and windfarm development (Arnett et al, 2016).…”

Bats are an important group of mammals, frequently foraging in farmland and potentially exposed to pesticides. This statement considers whether the current risk assessment performed for birds and ground dwelling mammals exposed to pesticides is also protective of bats. Three main issues were addressed. Firstly, whether bats are toxicologically more or less sensitive than the most sensitive birds and mammals. Secondly, whether oral exposure of bats to pesticides is greater or lower than in ground dwelling mammals and birds. Thirdly, whether there are other important exposure routes relevant to bats. A large variation in toxicological sensitivity and no relationship between sensitivity of bats and bird or mammal test-species to pesticides could be found. In addition, bats have unique traits, such as echolocation and torpor which can be adversely affected by exposure to pesticides and which are not covered by the endpoints currently selected for wild mammal risk assessment. The current exposure assessment methodology was used for oral exposure and adapted to bats using bat-specific parameters. For oral exposure, it was concluded that for most standard risk assessment scenarios the current approach did not cover exposure of bats to pesticide residues in food. Calculations of potential dermal exposure for bats foraging during spraying operations suggest that this may be a very important exposure route. Dermal routes of exposure should be combined with inhalation and oral exposure. Based on the evidence compiled, the Panel concludes that bats are not adequately covered by the current risk assessment approach, and that there is a need to develop a bat-specific risk assessment scheme. In general, there was scarcity of data to assess the risks for bat exposed to pesticides. Recommendations for research are made, including identification of alternatives to laboratory testing of bats to assess toxicological effects.
