Homogenisation of Vegetation in Irish Semi-Natural Grasslands. [PDF]

Ecol Evol
A re‐survey of 12 Irish grassland sites revealed a decrease in species number and an apparent shift towards homogeneity of species diversity over the last 12–15 years. This raises concerns about management and species diversity/conservation. ABSTRACT Grasslands represent an important source of vegetative diversity and provide a range of important ...

Divergent Phosphorus-Mining Strategies in Simple and Compound Cluster Roots in Extremely Phosphorus-Impoverished Soils in Southwest Australia. [PDF]

Plant Cell Environ
ABSTRACT Most Proteaceae and some Fabaceae species produce specialised cluster roots (CRs), and are abundant in severely phosphorus (P)‐impoverished soils in southwest Australia. Two types of CRs, compound and simple, have been identified. However, the difference in their P‐mining strategies remains unclear. Therefore, we conducted glasshouse and field

Revisiting the relationship between stomatal size and speed across species - a meta-analysis. [PDF]

New Phytol
Summary The rate of stomatal opening and closure in response to changes in light affects leaf photosynthesis and water use. However, it is unclear how strongly stomatal size (SS) and density (SD) influence stomatal conductance (gs) kinetics, and whether variation arises from methodological differences, guard cell type or degree of amphistomaty.

Floristic Diversity and Indicator Species Analysis Along Altitudinal Gradients of the Upper Indus Basin, Northern Pakistan. [PDF]

Ecol Evol
Altitudinal gradients substantially influence floristic diversity and indicator species. Three vegetation communities were identified, each shaped by specific environmental variables. Mantel test shows that altitude, Ca, K, Na are key drivers of species diversity and association.

Genes Translocated into the Plastid Inverted Repeat Show Decelerated Substitution Rates and Elevated GC Content. [PDF]

, 2016
Plant chloroplast genomes (plastomes) are characterized by an inverted repeat (IR) region and two larger single copy (SC) regions. Patterns of molecular evolution in the IR and SC regions differ, most notably by a reduced rate of nucleotide substitution ...
