Premise Of The Study: Senna spectabilis var. excelsa (Fabaceae) is a South and Central American tree of great ecological importance and one of the most common species in several sites of seasonally dry forests. Our goal was to develop microsatellite markers to assess the genetic diversity and structure of this species.
Methods And Results: We designed and assessed 53 loci obtained from a microsatellite-enriched library and an intersimple sequence repeat library. Fourteen loci were polymorphic, and they presented a total of 39 alleles in a sample of 61 individuals from six populations. The mean values of observed and expected heterozygosities were 0.355 and 0.479, respectively. Polymorphism information content was 0.390 and the Shannon index was 0.778.
Conclusions: Polymorphism information content and Shannon index indicate that at least nine of the 14 microsatellite loci developed are moderate to highly informative, and potentially useful for population genetic studies in this species.

Background: The endangered Kashmir musk deer (Moschus cupreus), native to high-altitude Himalayas, is an ecological significant and endangered ungulate, threatened by habitat loss and poaching for musk pod distributed in western Himalayan ranges of India, Nepal and Afghanistan. Despite its critical conservation status and ecological importance in regulating vegetation dynamics, knowledge gaps persist regarding its population structure and genetic diversity, hindering effective management strategies.
Methods And Results: We aimed to understand the population genetics of Kashmir musk deer in north-western Himalayas using two mitochondrial DNA (mtDNA) regions and 11 microsatellite loci.

Background: Persimmon (Diospyros kaki L.) belongs to the Ebenaceae family, which includes six genera and about 400 species. This study evaluated the genetic diversity of 100 persimmon accessions from Hatay province, Türkiye using 42 morphological and pomological traits, along with inter simple sequence repeat (ISSR) markers and multivariate analysis.

Diadromous fish, in particular, are threatened throughout their marine and freshwater habitats. The conservation of these species requires an in-depth understanding of their genetic diversity and structure, to better understand their adaptive potential.
