Tulips (Tulipa spp.) are one of the most widely appreciated plants worldwide, nevertheless species taxonomy and biogeography are often poorly understood. Most wild tulips inhabit the mountains of Central Asia, a recognised biodiversity hotspot, and a centre of tulip diversity. Despite the presence of several country-level endemic Tulipa species, most taxa span the borders of several nations. With no globally Red Listed tulip taxa from this region national level conservation assessments are an important resource. Nonetheless, threats posed to tulips are still inadequately understood, especially climate change, and given the trans-national nature of most species, distributional information is restricted and often misleading. Here we collate 330 species records from the Global Biodiversity Information Facility with 85 newly collected records, to undertake species distribution modelling (MaxEnt) for ten native Central Asian species. This work showed that regional level models provide a much more comprehensive understanding of species’ extinction risks, proportions of habitat in different countries, and limitations in protected area coverage. Furthermore, our climate modelling, the first of its kind for tulips, suggests that climate change will have a significant negative impact on the range size of all species; including those that are currently widespread. We therefore add climate change to the list of threats affecting tulip populations in Central Asia, which already includes livestock overgrazing, urbanisation, wild collection, and mining. Overall, our work shows that although national information is important, a regional approach is crucial not just for tulip conservation efforts, but likely for Central Asian plant conservation in general.
В статье дана краткая ботаническая характеристика и оценка использования полыни зеленой (Artemisia viridis Willd.). Приводится описание растительных сообществ с полынью зеленой в пяти районах произрастания в Суусамырской долине, в Ат-Башинском районе и в Сонкульской котловине Кыргызстана. На 11 обследованных участках отмечено проективное покрытие данного вида, подсчитано количество генеративных побегов на 1 м², определена урожайность надземной массы с 1 м² и с 1 га. Определена территория, на которой возможна заготовка лекарственного сырья (надземной массы) полыни зеленой, установлены биологический и эксплуатационный запасы. Потребность в лекарственном сырье постоянно растет, но перспективы использования дикорастущих видов достаточно ограничены. Перевыпас скота, хищническая заготовка лекарственных растений значительно сокращают запасы сырья и сборы его в природных местах произрастания. Необходимо более рационально использовать природные запасы лекарственного растительного сырья и заботиться об их сохранении и возобновлении. В зависимости от природно-климатических условий, ежегодно может развиваться различное количество генеративных побегов и, следовательно, изменяться урожайность сырья полыни зеленой. Это может привести к изменению биологического и эксплуатационного запасов. Ключевые слова: полынь зеленая, лекарственные травы, сырьевые запасы, генеративные побеги, заготовкаThis work gives a brief botanical facies and use of sagebrush green (Artemisia viridis Willd.). Description of plant communities is being held in which a sagebrush green (Artemisia viridis Willd.) in 5 habitats in the Suusamyr Valley, in the At -Bashi District and in the Sonkul Basin of Kyrgyzstan. The projective cover of this species was noted in 11 surveyed plots, the number of generative shoots per 1 m 2 was calculated, the productivity of the aboveground mass from 1 m 2 and 1 ha was determined. The territory on which the preparation of medicinal raw materials (above -ground mass) of sagebrush green is defined, biological and operational stocks have been established. The need for medicinal raw materials is constantly growing, but the prospects for the use of wilding species are enough limited. Depending on the nature -climatic conditions, the various quantities of generative shoots annually may evolve, and therefore, they yield of raw materials of sagebrush green can change. This could lead to changes in biological and operational reserves.
Tulipa toktogulica (T. sect. Kolpakowskianae; Liliaceae) is a cryptic new species from the Toktogul area of the Jalal-Abad Region, Kyrgyzstan. It is similar to T. talassica, with which it shares the characteristically elongated tunic, but it is genetically and geographically distinct. It has a combination of morphological traits shared between the closely related species T. talassica, T. tetraphylla and T. ferganica, but the combination of its traits is unique. Unlike most other members of the genus, this new species has a scent. It is here also assessed as endangered due to its narrow range and continuing threats from overgrazing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
