<em>Abstract</em>.—Largemouth Bass <em>Micropterus salmoides</em> ranges naturally in Mexico from the binational Rio Grande basin, including Cuatro Ciénegas valley in the state of Coahuila, southward and eastward through two adjacent Gulf Coast drainages, the Río San Fernando and Río Soto La Marina in Nuevo León and Tamaulipas. Within this range, Florida Bass <em>M. floridanus</em> has been introduced into reservoirs in at least the Río Grande and Soto La Marina basins. To assess the conservation status of native Mexican bass, we study genetic variability within and among Largemouth Bass populations and the degree of genetic introgression by Florida Bass within them. We sampled numerous localities in Cuatro Ciénegas, the San Fernando and Río Soto La Marina basins, and Vicente Guerrero Reservoir, where Florida Bass was introduced. We examined restriction-fragment polymorphisms within the 12S and 16S ribosomal RNA mitochondrial DNA genes and genotypes at two allozyme and five microsatellite DNA loci. Levels of introgression were quantified by Bayesian assignment testing using the nuclear data. Largemouth Bass specimens possessed generally lower nuclear diversity, but higher mitochondrial diversity, than those of Florida Bass. Populations from Cuatro Ciénegas differed from those in the San Fernando and Soto La Marina basins. Nuclear analyses revealed three genetically pure populations in Cuatro Ciénegas (Charcos Prietos, Las Playitas, and Canal del Tío Julio), but hybrids in Río Garabatal and Mojarral Este. Another presumably pure Largemouth Bass population was found in Río El Tigre of the Soto La Marina drainage. Our results could be explained by geographic barriers, sex-biased dispersion, hybrid disadvantage, or selection for coadapted gene complexes. More extensive surveys are needed to fully assess the conservation status of native Largemouth Bass populations in México. We anticipate that these will reveal additional native diversity. Meanwhile, the remnant native populations delineated herein are important to protect and we advocate that their ranges be managed as genetic conservation areas.

Abstract. Fauzi MA, Hamidy A, Kurniawan N. 2020. Harvesting trends of Amboina box turtles (Cuora amboinensis) seventeen years after listing in Appendix II CITES. Biodiversitas 21: 1142-1148. Among Southeast Asian freshwater turtles, the Amboina box turtle (Cuora amboinensis) held the highest recorded harvesting levels. The large volumes of harvesting influenced its International Union for Conservation of Nature (IUCN) revised the conservation status of C.amboinensis from Near Threatened to Vulnerable in 2000. The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) also inclusion of Amboina box turtle in Appendix II category. The CITES trade database provided a data set that tracks the legal trade of C. amboinensis in the global market from 2000 to 2017. Before 2005, Malaysia was the largest major supplier of this species to the global market. However, after 2005, Indonesia replaces Malaysia as the biggest exporter. From 2005 to 2014, the data showed that the trade trends already followed the quota of provisions. The trade routes of C amboinensis showed that the USA was the country to which these turtles were most frequently imported (50 times during 2000-2017), while China was still the biggest importer country in terms of quantity (463584 individuals from 2000-2017). The USA re-exported C. amboinensis for the pet trade to several European countries. Vietnam reportedly also re-exported C. amboinensis from Laos. However, Laos has rarely reported the occurrence of export activities to Vietnam. Based on these findings, we were able to understand the dynamics of the C. amboinensis trade globally more clearly, propose several actions deemed necessary for its conservation, and suggest greater on-going coordinated efforts to monitor the trade of this species.

The internationally renowned Muong Phang Cultural and Historical Site is located in the Dien Bien Phu region, northwestern Vietnam, and has received special attention from the public because of its great biodiversity. This site has a large forest area and other habitats including lakes, streams, rivers and paddyfield. These habitats would be ideal homes for bats and other biological taxa. However, in general, the wildlife of the Muong Phang Cultural and Historical Site receives little attention from scientists and authorities. Between 2014 and 2016, we conducted  series of surveys for bats in Muong Phang. Bat capture and sound recordings were the main procedure to obtain materials and data necessary for the assessment of diversity and conservation status. The results of the surveys this time revealed that there are 19 species of bats belonging to 7 genera, 5 families in the study area. Of these, a Myotis sp. is different from all the previously recorded Myotis bats from Vietnam, and, a Rhinolophus sp. is different from every described species of the family Rhinolophidae. This paper provides the first records of bats from Muong Phang with remarks on their taxonomy and conservation status.   Citation: Dao Nhan Loi, Vu Dinh Thong, 2017.

A New Species

Abstract—A new species of Eugenia from the Atlantic forest of Brazil is described and illustrated. Eugenia flavicarpa is restricted to the Floresta de Tabuleiro (lowland forests) of Espírito Santo state and is nested in Eugenia subg. Pseudeugenia. Considering all other species of the subgenus that occur in forest vegetation types of the Atlantic forest phytogeographic domain, Eugenia flavicarpa can be distinguished mainly by the combination of smooth leaves with indumentum on both surfaces, with two marginal veins, usually ramiflorous inflorescences, pedicels 4.5‐9.7 mm long, flower buds 3.5‐4 mm in diameter, and by the calyx lobes that are 2‐3 mm long with rounded to obtuse apices. Morphological analyses were performed to explore the significance of quantitative diagnostic features between the new species and the closely related species, Eugenia farneyi. Notes on the habitat, distribution, phenology, and conservation status of Eugenia flavicarpa are provided, as well as a key for all species of Eugenia subg. Pseudeugenia from forest vegetation of the Atlantic forest phytogeographic domain.

Epimedium elatum (Morren & Decne) of family Berberidaceace is a rare perennial medicinal plant, endemic to high altitude forests of Northwestern Himalayas in India. Ethnobotanically, it has been used as an ingredient for treatment of bone-joint disorders, impotence and kidney disorders in Kashmir Himalayas. Phytochemically, it is rich in Epimedin ABC and Icariin; all of these have been demonstrated to possess remarkable biological activities like PDE-5 inhibition (treatment of erectile dysfunction), anticancer, antiosteoporosis antioxidant and antiviral properties. The present investigation reports its traditional usage, comprehensive distribution and conservation status from twenty ecogeographical regions in Kashmir Himalayas, India. The species was reported from Gurez valley for the first time. Numerous threats like excessive grazing, deforestration, habitat fragmentation, tourism encroachment, landslides and excessive exploitation have decreased its natural populations in most of the surveyed habitats. Consequently, its existence may become threatened in near future if timely conservation steps are not taken immediately by concerned stakeholders involved in medicinal plant research. Moreover, use of plant tissue culture techniques is recommended for development of its in vitro propagation protocols. Therefore, introduction of this medicinal plant in botanical gardens, protected sites and development of monitoring programmes are needed for its immediate conservation in Northwestern Himalayas, India.
