A few of the >1300 bat species recognised worldwide are known to consume fish to various extents. However, empirical information about how and how much different bat species capture and consume fish is limited and is probably distorted due to the biases introduced by occasional observations. In this review, we aim to synthesise the knowledge so far generated on fishing bats, in order to 1) assess the incidence of fishing in different bat species; 2) discuss the evolutionary framework and origins of fishing behaviour; and 3) identify the ecological challenges of fishing and review the state of knowledge about kinetic, morphological, sensory, behavioural, and physiological adaptations related to fishing. Fishing bats can be clustered into three groups based on the incidence of fish consumption. Noctilio leporinus is the only species in which fishing is widespread (occurring in most populations) and common (occurring most of the time and carried out by many individuals). Myotis vivesi, Myotis pilosus, and Myotis capaccinii comprise the second group, characterised by exhibiting regular fishing behaviour that is restricted to a limited number of populations. Noctilio albiventris, Myotis daubentonii, and Myotis macropus are classified in a third group, because although the occasional presence of fish traces in faeces has been reported, regular fishing behaviour in the wild has not been confirmed. Fishing was developed independently multiple times in different bat lineages, probably under different selective pressures and ecological scenarios. Nevertheless, all fishing species face similar challenges in terms of detecting, capturing, handling, and metabolising fish, which require specific kinetic, morphological, sensory, behavioural, and physiological adaptations. Both basic information about fishing behaviour in different species and specific knowledge of the biological adaptation are still missing. Thus, in this review we identify gaps in the knowledge and suggest experimental approaches to overcome them.

“…In addition, the knowledge about species' life-history aspects (e.g. Cheng and Lee, 2002;Ho and Lee, 2003;Ma et al, 2006;Park et al, 2000) generated in this century helps to assess the threatened status of bat species and plan effective conservation strategies (Mickleburgh et al, 2002). However, conservation-driven research is needed to draw efficient conservation actions (Weeks and Adams, 2017).…”

Research trends on bats in China: A twenty-first century review

a b s t r a c tIn this century, China has sustained unparalleled economic development, leading to exponentially growing investments in scientific research. Yet, the demand for research-funding is large and tracing the current knowledge is a key step to define priority research topics. In this same span, studies on bats in China have uncovered an overlooked diversity and revealed novelties in bats' evolutionary history and life-history aspects. All this 21st-century knowledge, however, is scattered and a large part is concealed from most of the international scientific community in Mandarin-language articles. Here, we summarize the post-millennium (2000-2017) research on bats in China and point out trends and future directions based on neglected topics, groups, and regions. In addition, we provide an up-to-date list of bat species in China. We retrieved 594 publications related to bats in China, nearly half were written in Mandarin. At least 147 bat species are present in China, which places it among the most bat-rich countries in the world. There was a significant positive trend on the number of publications, from 12.5 annual average in 2000-2005 to 46.5 in recent years, reflecting the Chinese economic-scientific development in this century. We found marked taxonomic and spatial biases. Half of the studies in this century focused on Rhinolophus, Myotis, and Hipposideros, and the southern and eastern provinces were the most studied. Systematic/taxonomy and Ecology were the predominant topics post-millennium, whereas only 10 articles have clear conservation-driven goals. Our review shows that the majority of studies were focused on the least concern, cave-dweller species, and on bat-rich provinces. Future projects should address the effects of human-modified landscapes on bat community to define proper conservation actions. We discuss some priority actions and projects that will help to enhance bat protection in China.

“…Beetles are frequently eaten by Pipistrellus, Nyctalus, Murina, and Ia species (Jones 1995;Lee and Lee 2005;Thabah et al 2007;Ma et al 2008), whereas Barbastella-in which gene duplication was absent-is known to specialize on softer bodied insects such as moths (Rydell et al 1996). Apart from fish, beetles are also the main prey of M. ricketti (Ma et al 2006), although the congeners M. siligorensis and M. lucifugus are thought not to specialize on beetles (Wei et al 2006;Burles et al 2008). Our integrated results suggest that gene duplication with subsequent functional modification of lysozymes in vespertilionid bats is likely to have contributed to the success and diversification of insect-eating bats.…”

The role of gene duplication in generating new genes and novel functions is well recognized and is exemplified by the digestion-related protein lysozyme. In ruminants, duplicated chicken-type lysozymes facilitate the degradation of symbiotic bacteria in the foregut. Chicken-type lysozyme has also been reported to show chitinase-like activity, yet no study has examined the molecular evolution of lysozymes in species that specialize on eating insects. Insectivorous bats number over 900 species, and lysozyme expression in the mouths of some of these species is associated with the ingestion of insect cuticle, suggesting a chitinase role. Here, we show that chicken-type lysozyme has undergone multiple duplication events in a major family of insect-eating bats (Vespertilionidae) and that new duplicates have undergone molecular adaptation. Examination of duplicates from two insectivorous bats-Pipistrellus abramus and Scotophilus kuhlii-indicated that the new copy was highly expressed in the tongue, whereas the other one was less tissue-specific. Functional assays applied to pipistrelle lysozymes confirmed that, of the two copies, the tongue duplicate was more efficient at breaking down glycol chitin, a chitin derivative. These results suggest that the evolution of lysozymes in vespertilionid bats has likely been driven in part by natural selection for insectivory.
