Wind energy production is growing rapidly worldwide in an effort to reduce greenhouse gas emissions. However, wind energy production is not environmentally neutral. Negative impacts on volant animals, such as bats, include fatalities at turbines and habitat loss due to land-use change and displacement. Siting turbines away from ecologically sensitive areas and implementing measures to reduce fatalities are critical to protecting bat populations. Restricting turbine operations during periods of high bat activity is the most effective form of mitigation currently available to reduce fatalities. Compensating for habitat loss and offsetting mortality are not often practiced, because meaningful offsets are lacking. Legal frameworks to prevent or mitigate the negative impacts of wind energy on bats are absent in most countries, especially in emerging markets. Therefore, governments and lending institutions are key in reconciling wind energy production with biodiversity goals by requiring sufficient environmental standards for wind energy projects.

Tonatia bidens is listed as 'Data Deficient' in the IUCN Red List. Our research, conducted in the Brazilian Caatinga dry forest between 2016 and 2022, aimed to shed light on the diet of this little-known species. Thirty-eight taxa were identified among insect remains beneath T. bidens' feeding perch. Notably, certain insects such as hawkmoths and cerambycid beetles are agricultural pests with significant negative impacts on crops, including cassava, corn, tomato, papaya, and cashew plantations. These results underscore bats' crucial role in insect pest consumption, emphasizing the need for further studies to fully understand their diet and ecosystem contributions. [ABSTRACT FROM AUTHOR]

Bats can be parasitized by several arthropod groups, including ectoparasitic flies. The high host specificity is a common phenomenon between flies and bats. In recent years, more efforts have been employed to understand how environmental variables can influence richness and parasitic load (PL). However, many gaps still need to be filled to better understand this issue. We analyzed the PL of flies on bats sampled in three environments with different rain volume and vegetation types to verify if PL is correlated with rainfall and if there are differences in the PL on bats within and between environments. Overall, there was no correlation between rainfall and PL in the same environment, nor a difference between the three environments. When tested separately, Seba's short-tailed bats (Carollia perspicillata (Linnaeus, 1758)) had a difference in prevalence of flies between environments and flat-faced fruit-eating bats (Artibeus planirostris (Spix, 1823)) had a greater abundance of flies in the rainy season in a semiarid area. There was no difference in PL between male and female bats. Our results suggest that bat--fly interactions are driven by several factors, not only by the amount of rainfall or vegetation, and that different host species may respond differently with no obvious general pattern.

Les chauves-souris peuvent être parasitées par plusieurs groupes d'arthropodes, dont des mouches ectoparasites. Une forte spécificité des hôtes est un phénomène répandu entre les mouches et les chauves-souris. Ces dernières années, plus d'efforts ont été déployés pour comprendre l'influence possible de variables environnementales sur la richesse et la charge de parasites (CP). De nombreuses lacunes demeurent cependant à combler pour mieux comprendre cette question. Nous analysons la CP de mouches sur des chauves-souris échantillonnées dans trois milieux caractérisés par différents volumes de pluie et types de végétation, afin de vérifier si elle est corrélée à la pluviosité et s'il existe des variations de la CP des chauves-souris à l'intérieur des milieux et entre eux. Globalement, il n'y a pas de corrélation entre la pluviosité et la CP dans un même milieu, ni de différences entre les trois milieux. Prises individuellement, la chauve-souris de Seba (Carollia perspicillata (Linnaeus, 1758)) montre une variation de la prévalence de mouches entre les milieux et l'artibée commune (Artibeus planirostris (Spix, 1823)) est caractérisée par une plus grande abondance de mouches durant la saison des pluies dans une région semi-aride. Il n'y a pas de différences de la CP entre les chauves-souris mâles et femelles. Nos résultats donnent à penser que les interactions chauves-souris--mouches sont modulées par plusieurs facteurs, pas seulement la quantité de pluie ou la végétation, et que différentes espèces hôtes peuvent réagir différemment sans motif général évident.

Bats are highly mobile animals, moving rapidly over long distances. Detecting such movements is challenging, especially in cave areas, a commonly-used roost by bats. Brazil has a large number of caves and bat species, but details on bat mobility among caves is still poorly documented there. Such monitoring provides insights on the structuring and conservation of cave-dwelling communities, with possible legal implications for the environmental licensing in Brazil. Based on marking (2,490 bats captured; 2,142 marked) and recapture (35 events; 14 extra-site), here we present data on the mobility of mormoopid bats between two bat caves 15 km apart in northeastern Brazil. Sexual segregation between caves may explain mobility: one cave is likely a maternity roost; the other is a satellite cave used for copulae. Nomadic behavior due to seasonal distribution of resources in the semi-arid Northeastern Brazil cannot be ruled out. Based on the distance between the two caves, bats could potentially forage over an area of ~170,000 hectares, in a wider use of the landscape. Our data have implications for the conservation of bat species and their roosts, and contribute to a more evidence-based discussion of key concepts governing the environmental licensing of mining activities in Brazil.
