Morphological and Anatomical Characteristics of Herbaceous Plant Leaves in Different Light Intensities in Education Forest of Forestry Faculty of Mulawarman University [PDF]

open access: yes, 2017
This study objective was to know the morphological and anatomical characteristics of dominant herbaceous plant leaves in different light intensities. Three selected study sites represented heavy, moderate, and few light intensities. The vegetation survey

Individualistic responses of forest herb traits to environmental change [PDF]

open access: yes, 2020
Intraspecific trait variation (ITV; i.e. variability in mean and/or distribution of plant attribute values within species) can occur in response to multiple drivers.

High functional diversity is related to high nitrogen availability in a deciduous forest - evidence from a functional trait approach [PDF]

open access: yes, 2010
The current study tested the assumption that floristic and functional diversity patterns are negatively related to soil nitrogen content. We analyzed 20 plots with soil N-contents ranging from 0.63% to 1.06% in a deciduous forest near Munich (Germany ...

Anthropogenic seed dispersal: rethinking the origins of plant domestication

open access: yes, 2020
It is well documented that ancient sickle harvesting led to tough rachises, but the other seed dispersal properties in crop progenitors are rarely discussed. The first steps toward domestication are evolutionary responses for the recruitment of humans as
