Pollen Viability, Germination and Tube Elongation Responses to Heat Stress During the Reproductive Stage in Maize

Journal of Agronomy and Crop Science, Volume 212, Issue 5, September 2026.
ABSTRACT Climate change‐induced heat stress increasingly threatens crop production, particularly when high temperatures occur during the sensitive flowering stage. In maize, successful fertilization depends on viable pollen, successful pollen germination and subsequent pollen tube elongation reaching the ovule.

The incredible vulnerability that reproduction poses for plant species in a warming world

New Phytologist, Volume 251, Issue 6, Page 3111-3118, September 2026.
Generalized plant responses to heat stress across whole‐plant and reproductive scales. Summary Temperatures are rising globally and threatening the persistence of natural plant populations. Elevated temperatures disrupt gametogenesis, fertilization, and seed filling, often at lower thresholds than those affecting photosynthesis, growth, or survival ...

The richness, frequency and relatedness components of mate diversity and mate portfolios

New Phytologist, Volume 251, Issue 6, Page 3703-3713, September 2026.
The effects of (a) equal and (b, c) unequal contributions to mate portfolios by 10 mates on (d) Hill‐number mate diversity profiles (see Eqn 1). Summary Sexual reproduction produces genetically diverse families, especially when individuals mate with multiple partners.

Discriminating Arid Ecosystems and Tracking Desertification Dynamics: Evidence From Grain‐Size End‐Member in the Manas River Basin, Northern Tianshan Mountains

Land Degradation &Development, Volume 37, Issue 14, Page 10174-10186, 30 August 2026.
ABSTRACT The ecosystem of the Manas River Basin, composed of mountains, oases, and deserts, constitutes an ideal natural laboratory for investigating surface processes and environmental evolution in arid regions. Elucidating the provenance, transport dynamics, and climate response mechanisms of surface sediments in this system is critical for advancing

Malectin Alleviates Endoplasmic Reticulum Stress in Gestational Diabetes Mellitus via Glycoprotein Quality Control Mechanisms

Advanced Science, Volume 13, Issue 46, 17 August 2026.
Malectin alleviates high glucose‐induced ER stress and damage in placental trophoblasts, a function dependent on its six critical carbohydrate‐binding residues. In a GDM mouse model, administration of TAT‐Malectin ameliorated hyperglycemia and placental ER stress and prevented fetal macrosomia.

Ecology and evolution of pyrazines in insects

Biological Reviews, Volume 101, Issue 4, Page 1937-1959, August 2026.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Mutualism and Antagonism in a Post‐Extinction Hawaiian Bird–Lobelioid Pollination System

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Species loss can restructure plant–pollinator interactions, but the functional consequences of altered interactions remain unclear. Using camera observations and experimental manipulations in Hawaiian lobelioids, we show that nectarivorous birds differ in whether visits result in pollen contact or nectar robbing, with robbing altering nectar dynamics ...

Assessing Biodiversity in Agricultural Landscapes Through Drone‐Based Environmental DNA Sampling

Ecology and Evolution, Volume 16, Issue 8, August 2026.
We developed a drone‐based environmental DNA (eDNA) swabbing method to assess hexapod diversity in agricultural fields under three management types (conventional, organic, and IP‐Suisse), detecting 75 taxa across 19 families. eDNA replicates showed consistent within‐field results, though no significant differences in diversity were found between ...

Signals of Paleotemperature in the Age Structure and Seasonal Distribution of Pollination Syndromes Across a Temperate Region

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Species with wind & insect pollination syndromes show distinct age structure patterns. Splitting insect pollination into different categories show constrasting age structure. Modern flowering seasons track paleotemperature signatures. ABSTRACT Across the planet, angiosperm diversification has been shaped by palaeoclimates and biotic interactions ...
