Wei Zhang bis & J.W.Shao, a new species from Hunan Province, China, is described. Its leaf morphology is similar to the complex and flower morphology similar to , but it can be distinguished from the former by the black pollen sac, corolla lobes apex obviously emarginate and can be differed from the latter by cotyledon triangular obovate, plants densely covered with glandular hairs and special habitat (karst caves). The whole plastid genome of this new species is 151, 601-151, 630 bp in length. Based on the whole plastid genome sequences, phylogenetic trees revealed that the new species did not genetically relate to the above two mentioned morphologically similar species, but it was closely related to . Currently, only three populations were discovered within a small distribution area, thus, it is preliminarily considered as Vulnerable (VU) according to criteria of the IUCN Red List.

Karst caves are a unique environment significantly different from the external environment; adaptation of cave-dwelling animals to the cave environment is often accompanied by shifts in the sensory systems. Aquatic and terrestrial leeches have been found in the karst caves. In this study, we conducted a transcriptome analysis on the cave-dwelling leech .

In the long and complex process of geological evolution, the rise of the Himalayan movement and the strong Quaternary glacial movement 400,000 years ago have shaped the highly distinctive travertine landform landscape of Huanglong, China. The overflow of karst water in the high travertine layer has formed magnificent waterfalls and wonderful karst caves as well as the world's largest open-air travertine beaches and pools. The unique travertine landscape has entered the public's vision.

Article Synopsis
- Karst caves are unique ecosystems with low organic matter and high endemic biodiversity, particularly in microbes like testate amoebae (Arcellinida).
- Recent research in Dinaric karstic caves, using metabarcoding techniques, reveals that bat guano significantly enhances the diversity and abundance of Arcellinida communities.
- Findings suggest that bat guano creates rich habitats for unique Arcellinida species, emphasizing the important ecological role of bats in these subterranean environments.
Cave Pools in Carlsbad Caverns National Park Contain Diverse Bacteriophage Communities and Novel Viral Sequences.

Viruses are the most abundant biological entities on Earth, and they play a critical role in the environment and biosphere where they regulate microbial populations and contribute to nutrient cycling. Environmental viruses have been the most studied in the ocean, but viral investigations have now spread to other environments. Here, viral communities were characterized in four cave pools in Carlsbad Caverns National Park to test the hypotheses that (i) viral abundance is ten-fold higher than prokaryotic cell abundance in cavern pools, (ii) cavern pools contain novel viral sequences, and (iii) viral communities in pools from developed portions of the cave are distinct from those of pools in undeveloped parts of the same cave.

In karst landscapes, where sustainable water management is increasingly challenged by drought-induced water scarcity, the adoption of road-based rainwater harvesting (RBWH) systems has emerged as a promising solution for improving water accessibility. Despite the growing implementation of such systems, the effectiveness of many RBWH projects in karst terrains remains suboptimal due to an inadequate understanding of runoff generation mechanisms associated with hilly road networks. This study focuses on quantifying the contributions of intercepted surface runoff (SR) and soil-epikarst lateral flow (SEF) from a newly exposed road-cut slope in a dolomite hillslope, with data collected across 156 rainfall events from May 2019 to May 2022.
