Predicting the suitable habitat of the Pinus pumila under climate change

Journal of Environmental Impact Assessment, 2014
This study was performed to predict the future climate envelope of Pinus pumila, a subalpine plant and a Climate-sensitive Biological Indicator Species (CBIS) of Korea. P. pumila is distributed at Mt. seorak in South Korea. Suitable habitat were predicted under two alternative RCPscenarios (IPCC AR5).

Polyembryonic or Apomictic Seeds Enable Fig Trees to Establish New Populations Without Their Pollinating Wasps, a Case Observation in Ficus gasparriniana

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Development of apomictic adventitious embry o in Ficus gasparriniana. Apomixis is a key reproductive strategy for F. gasparriniana, especially when pollination by fig wasps is limited. In the absence of pollination, F. gasparriniana produces seeds through adventitious embryos formed within the nucellar tissue, which is accompanied by polyploidization ...

Effects of Niche Marginality on Hotter‐Drought Tree Mortality in Angiosperms and Gymnosperms

Global Ecology and Biogeography, Volume 34, Issue 9, September 2025.
ABSTRACT Aim Current observations of global tree mortality events associated with drought raise concerns about climate change risks to forests' dynamics and function. It is unclear which forests are more susceptible to pulses of mortality under further changing climates.

Vegetation and environmental dynamics in the central part of the Kola Peninsula during the past 13.3 ka as reflected by ancient plant DNA on sediments from Lake Imandra

Journal of Quaternary Science, Volume 40, Issue 6, Page 1070-1096, August 2025.
ABSTRACT The first high‐resolution reconstruction of the vegetation and environmental changes during the last ca 13 300 cal a BP in the central part of the Kola Peninsula (NW Russia) was reconstructed based on sedimentary ancient DNA (sedaDNA) metabarcoding on sediment core Co1410 from Lake Imandra.
