A new genus, Spele- oticus gen. n., is described with Nesticus navicellatus Liu & Li, 2013 as the type species, and four species are transferfed from Nesticus, i.e., Speleo...

This research involved the study of 31 species from the spider family Mysmenidae Petrunkevitch, 1928, found in the Gaoligong Mountains of China, including one new genus and 13 new species. Our results suggested that regression of East Tethys contributed to the appearance of a center of biodiversity.

The mitochondrial genome (mitogenome) is recognized as an effective molecular marker for studying molecular evolution and phylogeny. The family Mysmenidae is a group of widely distributed and covert-living spiders, of which the mitogenomic information is largely unclear. In this study, we obtained the first four complete mitogenomes of mysmenid spi...

Land use change has caused the loss of agricultural biodiversity. As major natural enemies of pests in agroecosystems, spiders have important ecological functions in improving agricultural productivity and thus deserve attention. However, few studies have considered their responses to land use changes. Here, we investigated the structure and divers...

The giant panda is a flagship species in ecological conservation. The infrared camera trap is an effective tool for monitoring the giant panda. Images captured by infrared camera traps must be accurately recognized before further statistical analyses can be implemented. Previous research has demonstrated that spatiotemporal and positional contextua...

Birds have been widely considered crucial indicators of biodiversity. It is essential to identify bird species precisely for biodiversity surveys. With the rapid development of artificial intelligence, bird species identification has been facilitated by deep learning using audio samples. Prior studies mainly focused on identifying several bird spec...
