Ecological and habitat ranges of orchids in the northernmost regions of their distribution areas: A case study from Ural Mountains, Russia

Plant Diversity, Journal Year: 2022, Volume and Issue: 45(2), P. 211 - 218

Published: Sept. 6, 2022

The Orchidaceae, which is one of the most interesting families angiosperms, contains a large number rare species. Despite their acknowledged importance, little attention has been paid to study orchids distributed in northern territories. In this study, we determined syntaxonomical diversity and ecological parameters orchid habitats two Europe's largest protected areas, Pechoro-Ilychsky Reserve Yugyd Va National Park (northeastern European Russia), then compared our findings those other parts distribution ranges. For purpose, studied 345 descriptions plant communities (releves) containing species from Orchidaceae defined habitat using Ellenberg indicator values with community weight mean approach, nonmetric multidimensional scaling (NMS), relative niche width. We found that were eight types 97 associations. forest communities. Half under occur mires rock open vegetation. Several consistently areas disturbed by human activity. addition, indicates main drivers across vegetation are light soil nitrogen. Our analysis some can be classified as specialists confined relatively narrow Urals (e.g., Goodyera repens, Cypripedium guttatum Dactylorhiza maculata). (e.g. Neottia cordata fuchsia) grow diverse parameters.

Comparison of Orchid Conservation Between China and Other Countries

Published: Nov. 12, 2024

Global attention is highly focused on biodiversity conservation. Various countries are actively implementing relevant conservation measures. To advance these efforts in China, it essential to understand global actions. The orchid family, one of the most diverse groups flowering plants, has become a “flagship” group for plant In this study, we summarized 3418 policies and regulations related 45 countries. We found that actions various have situ conservation, with 1469 issued nature reserves, while ex been seriously neglected, only seven regulations. Most developing experienced an increase actions, developed plateaued. amassed 370 non-governmental organizations (NGOs) At present, total number protection China approximately 84, 67 since 2000.

Through learning collaboration, challenges can be transformed into opportunities development.

Geographical pattern of the deviation between taxonomic, phylogenetic, and functional diversity and its implications for the conservation of Chinese orchids

Global Ecology and Conservation, Journal Year: 2024, Volume and Issue: 54, P. e03051 - e03051

Published: June 19, 2024

Orchidaceae stands as one of the "flagship" groups in global biodiversity conservation, attracting significant attention from researchers China. Previous studies have focused on taxonomic diversity, neglecting integration phylogeny and functional aspects. Here, we leveraged a large dataset distributions, evolutionary relationships, traits orchids China to analyze geographic patterns species richness (SR), weighted endemism (WE), phylogenetic diversity (PD), (PE), (FD), (FE). Furthermore, analyzed deviations between PD (or FD) SR (PDdev, FDdev), well PE FE) WE (PEdev, FEdev), taking into account climatic environmental variables. We also delineated priority protection survey areas orchid plants Our results revealed that SR, WE, PD, PE, FD, FE for generally exhibited similar trends. However, there were notable inconsistencies geographical PDdev, FDdev, PEdev, FEdev, which might be related different responses these four deviation metrics. pinpointed six conservation China, i.e., southeasterrn Xizang, western Yunnan, central Yunan, Karst area at border Guizhou Guangxi, Guangdong Taiwan Island.
