Influence of Myrmecophytic <i>Acacia drepanolobium</i> on the Composition and Growth of Surrounding Herbaceous Vegetation. [PDF]

open access: yesEcol Evol
In areas facing intense herbivory pressure, heavily defended trees like Acacia drepanolobium may serve as nurse plants, creating refugia microhabitats for the growth of vulnerable plants. Such refugia habitats promote diversity across the landscape and may also serve as recolonization nuclei for rare species.

Repeatability, Genetic Variability and Importance of Forage Traits in Ecotypes of Brunswickgrass (Paspalum nicorae Parodi) via BLUP

open access: yesPlant Breeding, EarlyView.
ABSTRACT This study estimated the repeatability of forage traits in 84 Paspalum nicorae ecotypes using six statistical methods and quantified the minimum number of harvests needed for effective selection. Multivariate analyses based on best linear unbiased prediction (BLUP) values were also performed to assess genetic variability, identify key traits ...
