Floristic composition of Palpa district, west Nepal

open access: yesNepalese Journal of Biosciences, 2014
The present study documents the floristic composition of the vascular plants (Pteridophytes, Gymnosperms, and Angiosperms) of Palpa district, West Nepal. A total of 467 species plants belonging to 163 families, 357 genera were recorded from the study area.

The effect of elevation on species richness in tropical forests depends on the considered lifeform: results from an East African mountain forest [PDF]

open access: yes, 2019
Elevation gradients in tropical forests have been studied but the analysis of patterns displayed by species richness and elevation have received little attention.

Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Floristic Composition Mediates Change in Forage Nutritive Quality of Atlantic Mountain Grasslands after Experimental Grazing Exclusion

open access: yesAgronomy, 2020
Simultaneous reduction of biodiversity and forage nutritive value after grazing abandonment represents a critical agroecological problem observed in temperate mountain grasslands. However, how both processes affect each other after the exclusion of large

Patterns of understorey bird diversity across Amazonian forests: survey effort and range maps predict local species richness

open access: yesEcography, EarlyView.
Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...

The Influence of Sheep Fertilizing and Oversowing on the Lawns of the Cindrel Mountain

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
Massive Cindrel natural grasslands have an estimated yield between 1.9 to 3 t / ha. Applying environmentally friendly technologies are expected to improve the yield crops by reducing to extinction the floristic composition of some species like Nardus ...

Dissecting the effects of simulated cattle activity on floristic composition and functional traits in Mediterranean grasslands. [PDF]

open access: yesPLoS ONE, 2013
Livestock exerts direct and indirect effects on plant communities, changing colonization and extinction rates of species and the surrounding environmental conditions. There is scarce knowledge on how and to what extent these effects control the floristic

Thinning after selective logging facilitates floristic composition recovery in a tropical rain forests of Central Africa [PDF]

open access: yes, 2011
In the Congo Basin, where most timber species are light-demanding, low logging intensities commonly implemented (1-2 trees harvested ha-1) do not provide sufficient canopy gaps to ensure species regeneration.
