Ecography, EarlyView.Globally, mountains are highly diverse ecosystems that serve as natural laboratories for testing ecological theories, while providing vital ecosystem services. Their biodiversity arises from the interaction between elevational gradients and topographic complexity, which generate strong variation in environmental conditions across short spatial scales ...

Pollen Germination and Pollen Tube Growth in Gymnosperms
Plants, 2021 Pollen germination and pollen tube growth are common to all seed plants, but these processes first developed in gymnosperms and still serve for their successful sexual reproduction.

Polyploidy in Gymnosperms [PDF]
Evolution, 1959 The gymnosperms constitute a primitive group of seed plants which have a considerable evolutionary interest. A substantial amount of literature on the morphology of the group exists, but very little has been written about the various cytogenetic factors responsible for evolution within the group.

Alpine flora of Kashmir Himalaya: floristic assessment, life history traits and threat status
Nordic Journal of Botany, EarlyView.Alpine ecosystems in the Himalaya are considered to be at a higher risk to anthropogenic global change drivers. The Kashmir Himalaya, located in the north‐western side of the Himalayan biodiversity hotspot, harbors a diverse alpine flora, which remains systematically little investigated.

Age ratio in groups of a social ungulate affects epizoochorous dispersal and diaspore exchanges
Oikos, EarlyView.Animal‐mediated seed dispersal is a key process in plant population dynamics, species distribution and ecosystem functioning. As long‐distance dispersal agents, ungulates help to maintain native plant populations facing abiotic changes in their habitat and habitat fragmentation or habitat loss.

PLANTS, PEOPLE, PLANET, EarlyView.Brazil's diverse flora is under several threats, with many unique lineages facing extinction, particularly in biodiverse regions like the Cerrado and campo rupestre. This study sheds light on the conservation needs of Cambessedesia (Melastomataceae), an endemic genus with 95% of its species endangered, using an approach to rank and prioritise species ...

PLANTS, PEOPLE, PLANET, EarlyView.In response to Chile's public policy to establish a national biodiversity inventory and monitoring system, we launched the HerbarioDigital.cl portal. We have digitised over 120,000 specimens representing more than 3,900 species from two Chilean herbaria, integrating them through a curated local taxonomic index.
