Comparative study of pollen morphology and fertility in Pyrus L. species under in situ and ex situ conditions in Greater Caucasus, Azerbaijan [PDF]

BIO Web of Conferences
A number of negative changes are observed in the pollen of the vast majority of plants distributed in polluted areas: morphological immaturity or the observation of sterile pollen grains during pollination, a quantitative decrease in the total ...

Frugivory‐mediated trophic cascades: how apex predators can shape the recruitment of a fleshy‐fruited tree

Oikos, Volume 2026, Issue 3, March 2026.
The recovery of large carnivores offers unique opportunities to study their cascading impacts on plant population dynamics. Medium‐sized carnivores, both prey and seed dispersers, are suppressed by apex predators, indirectly increasing seed‐eating rodent's populations and potentially altering plant establishment.

The Genetic Diversity, Population Structure, and Historical Dynamics of Wild Pyrus Species on the Yunnan–Kweichow Plateau

Horticulturae
Located in the southwestern region of China, the Yunnan–Kweichow Plateau, is closely related to the origins of Pyrus L. Despite this important status, there has been relatively little population genetics research focused on the wild Pyrus species in this

A Systematic Approach to Field Testing of Biological Products for Horticulture Is Required to Improve Food Security

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Food security challenges require immediate action to increase food production. Many biological products derived from plant, animal or microbial sources claim they sustainably increase yield, but there are concerns about biosecurity to be investigated before their introduction to the field.

Effects of Pyrolysis Control Parameters on the Structural Properties of Biomass‐Derived Activated Carbon Materials and Their Energy Applications

The Chemical Record, Volume 26, Issue 3, March 2026.
Tubular pyrolysis synthesis is a widespread method to produce activated carbons (ACs). This review focuses on the different controlling parameters of the tubular pyrolysis synthesis method and their influence on the performance of synthesized ACs, thereby considering both experimental aspects and the use of plant‐based biomasses (PBBs) as feedstock ...
