Pollen viability in Quercus robur L.

Archives of Biological Sciences, 2017
The variability of viability (germination rate and the length of pollen tubes) of fresh pedunculate oak (Quercus robur L.) pollen grains was studied in vitro on a medium containing 15% sucrose. Spatial variability was studied by sampling fresh pollen grains from a total of thirteen trees at four different sites in the area of Belgrade ...

Soil remineralization with silicate rock powder: nutrient effects on plant quality and ungulate foraging

Restoration Ecology, EarlyView.
Abstract Introduction Silicate rock powder (SRP), a slow‐release mineral additive, is increasingly used as a potential mitigation measure against soil acidification in natural areas. SRP addition has led to a higher soil base saturation and small increases in soil nutrient availability.

Multi‐decadal woodland recovery after land abandonment: environmental constraints on passive rewilding in Mediterranean landscapes

Restoration Ecology, EarlyView.
Abstract Introduction Across the Mediterranean Basin, land abandonment has opened large areas to passive rewilding, raising questions about the pace and variability of secondary succession in these landscapes and how ecological and abiotic gradients mediate vegetation recovery in post‐agricultural landscapes. Objectives This study aims to quantify long‐

Image Databases for Pollen Grain Classification: Availability, Quality, and Challenges

WIREs Data Mining and Knowledge Discovery, Volume 16, Issue 3, September 2026.
Overview of the study process, from identifying gaps in pollen image databases to a systematic search across six libraries, resulting in 73 final studies, 18 datasets (10 public), and a seven‐point standardization framework proposed under FAIR principles.

Water Availability and Hydraulic Strategies Control Leaf Thermoregulation and Damage During Heat Stress and Recovery in Temperate Tree Species

Plant, Cell &Environment, Volume 49, Issue 9, Page 6296-6310, September 2026.
ABSTRACT Heatwaves are intensifying worldwide, often coinciding with high vapour pressure deficit (VPD) and soil drought. Yet, how temperate tree species tolerate these combined stresses remains elusive. Using single‐tree gas‐exchange chambers, we examined the response of leaf gas exchange and thermoregulation of three broadleaved tree species to a ...

Zagros Restoration: Smart Choices for Oak Forests

Land Degradation &Development, Volume 37, Issue 14, Page 10284-10307, 30 August 2026.
ABSTRACT Widespread forest degradation across the northern Zagros region of Iran driven by both human activity and natural processes has created an urgent need for targeted afforestation and forest enrichment strategies. Hence, the aim of this study was identifying the most suitable native tree and shrub species for restoring degraded forest areas in ...

Genetic diversity of Quercus robur, Quercus petraea and their hybrids in Lithuania

RURAL DEVELOPMENT 2019, 2013
Genetic diversity is an integral component of biodiversity. Genetic diversity being a reliable basis in the evolution of forest woody plants has helped forests and woody species to adapt to changing and unfavourable conditions and has contributed to the formation of unique, irreplaceable genetic resources of forest woody plants for thousands of years ...

Decaying Logs Shape the Distribution of Bird‐Mediated Seed Rain in a Temperate Deciduous Forest

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Sites used by birds for perching and roosting function simultaneously as defecation points, concentrating diaspores transported via endozoochory. In contrast, the role of perching structures in shaping bird‐mediated seed rain within forest ecosystems remains poorly understood.
