Symbiotic Germination Technique of an Endangered Epiphytic Orchid Dendrobium sinominutiflorum: A Promising Conservation Application 濒危附生兰科植物勐海石斛 (Dendrobium sinominutiflorum) 的共生萌发技术:一种具有应用前景的保护策略

open access: yesIntegrative Conservation, EarlyView.
We developed an effective ex‐situ conservation approach for an endangered orchid species, Dendrobium sinominutiflorum. A compatible fungal strain Tulasnella sp. was obtained by using in‐situ seed baiting technique.

Evolution and Phylogenetics of the Javan Hawk‐Eagle Nisaetus bartelsi (Stresemann, 1924) Using Mitochondrial Data 爪哇鹰雕 Nisaetus bartelsi (Stresemann, 1924) 基于线粒体数据的演化与系统发育研究

open access: yesIntegrative Conservation, EarlyView.
This study reconstructs the phylogeny of the Javan Hawk‐Eagle (Nisaetus bartelsi) within the subfamily Aquilinae using Maximum Likelihood and Bayesian Inference algorithms on a blood sample and GenBank data. The analysis reveals that the sampled genus Nisaetus forms a monophyletic group. Furthermore, N. bartelsi occupies a sister‐taxon of N.

Fire‐induced shifts in activity patterns of predators and prey in the Brazilian Pantanal

open access: yesThe Journal of Wildlife Management, EarlyView.
Using camera trap data, we observed that 5 of 6 prey species showed statistically significant changes in temporal activity patterns, while jaguars were the only predator species to adjust activity when comparing pre‐fire and post‐fire periods in an isolated rocky formation in the Pantanal region.

open access: yesNordic Journal of Botany, EarlyView.
Vitex L. is a pantropical genus of Lamiaceae comprising 209 taxa. Brazil harbors 35 species, representing nearly 50% of the genus richness in the Neotropics, with the Amazon showing the highest richness, followed by the Atlantic Forest and Cerrado domains. Nevertheless, most taxonomic studies of the genus have been conducted in Africa and Asia.
