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

open access: yesEcol 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.

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

open access: yesEcol 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 ...

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

open access: yesNew 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.

Serial section videography (SSV): A low-cost protocol for generating 3D reconstructions of internal plant structure. [PDF]

open access: yesAppl Plant Sci
Abstract Premise Analyzing structural changes along the length of an organ provides insight into its development. However, traditional histological methods are limited by intensive procedures and size restrictions. Micro‐computed tomography (microCT) enables non‐destructive internal imaging along the length of an organ, but high cost, technical ...
