Lichens in Forest Park and Nitrogenous Air Pollution [PDF]

open access: yes, 2014
Lichens have been shown to be useful bioindicators for determining levels of nitrogen deposition related to air pollution. Preliminary lichen surveys in Forest Park in 2011 and 2012 revealed the presence of lichen species associated with high levels of ...

Long‐term outcomes of microsurgical interdental papilla reconstruction: 13‐year and 18‐year case follow‐ups

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Loss of the interdental papilla compromises esthetics, speech, and hygiene, significantly affecting quality of life and psychological well‐being. Reconstruction has long been considered unpredictable, particularly in Cairo RT3 cases with advanced interproximal bone loss.

Warming summers limit reindeer grazing, weakening herbivory pressure in the mountain tundra

open access: yesEcography, EarlyView.
Climate change is predicted to alter species interactions by exposing ecosystems to increasingly frequent and intense warm spells. In the mountain tundra, grazing by large herbivores, particularly reindeer, can limit shrub expansion and preserve Arctic plant diversity.

Vegetation on the move: elevational shifts and greening dynamics across the Himalayan alpine zone

open access: yesEcography, EarlyView.
This study investigates alpine ‘vegetation line' (the upper limit of continuous plant community) dynamics in the Himalayan alpine zone (HAZ) over a 24‐year timescale (1999–2022) using maximum NDVI products derived from Landsat series datasets, adjusted for sampling bias using phenological modelling.
