Wind‐driven seed dispersal differentially promotes seed trapping and retention across alpine plants
American Journal of Botany, EarlyView.Abstract Premise Seed dispersal can mediate species interactions between plants across life stages. Plants can physically stop seed movement (seed trapping) and prevent further dispersal following entrapment (seed retention). We therefore hypothesized seed trapping and retention rates depend on the physical attributes of interacting seeds and plants ...

Environmental Sciences Proceedings, 2023 Understanding the extent and location of snow cover is crucial for studying climate, hydrology, and ecosystems. Remote sensing, such as EUMETSAT’s H-SAF project, enables snow-cover monitoring using SEVIRI satellite data.

American Journal of Botany, EarlyView.Abstract Premise Species of Deuterocohnia (17 spp.) show extraordinary variation in elevation (0–3900 m a.s.l.) and growth forms, and many have narrow geographic distributions in the west‐central Andes and the Peru‐Chile coast. Previous research using few plastid and nuclear loci failed to produce well‐resolved or supported phylogenies.

Atmosphere, 2022 Snow cover area is dramatically decreasing across the Los Andes Mountains and the most relevant water reservoir under drought conditions. In this sense, monitoring of snow cover is key to analyzing the hydrologic balance in snowmelt-driven basins.

American Journal of Botany, EarlyView.Abstract Premise High‐latitude plants initiate flower primordia at least 1 year before flowering. While impacts of rising temperatures on phenology in the flowering year are well studied, the effects of warmer temperatures in the initiation year (IY; the year before flowering) are virtually unknown.

The new indices to describe temporal discontinuity of snow cover on the Qinghai-Tibet Plateau
npj Climate and Atmospheric ScienceSnow cover on the Qinghai-Tibet Plateau significantly impacts the climate, hydrology, and ecology of China and East Asia. Current studies mainly use snow cover days to describe its duration, overlooking the snow’s discontinuous nature.

International Journal of Digital Earth, 2017 Snow cover plays an important role in hydrological processes and seasonal water balance. Especially in the Tibetan Plateau (TP), snow cover is an important source of the Yangtze River, Yellow River and Lancang River (SRYYL), which greatly influences ...

Assimilation of snow cover and snow depth into a snow model to estimate snow water equivalent and snowmelt runoff in a Himalayan catchment [PDF]
The Cryosphere, 2017 Snow is an important component of water storage in the Himalayas. Previous snowmelt studies in the Himalayas have predominantly relied on remotely sensed snow cover. However, snow cover data provide no direct information on the actual amount of water

Applications in Plant Sciences, EarlyView.Abstract Premise Seed dispersal is a critical process for plant community assembly; however, natural rates of seed arrival are rarely quantified compared with other assembly mechanisms, especially in herbaceous communities. Methods Here we compare the utility of artificial grass carpet squares (“artificial grass”) for capturing seed rain with classic ...
