Elevated UV‐B alters anti‐herbivore plant defence allocation, while silicon supplementation maintains resistance

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The impacts of elevated surface ultraviolet‐B (UV‐B) on ecological processes, such as anti‐herbivore defence in plants, remain poorly understood. Many cereal crops depend on accumulating silicon (Si) in their tissues to resist insect herbivory.

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

tRNA species in the developing grain of triticum aestivum

Phytochemistry, 1975
The level of lysyl- and prolyl-tRNA in various stages of the maturing wheat grain was measured by the aminoacylation procedure. The levels of these tRNAs changed only slightly during the maturation period. Several species of lysyl- and prolyl-tRNA were obtained from different parts of the developing grain by fractionation on benzoylated-DEAE cellulose (

Drivers of Mouse Plagues: Exceptional Rainfall Following Prolonged Drought Triggers Mouse Plagues in Southeastern Australia

Integrative Zoology, EarlyView.
This study identified a specific sequence of an extended drought followed by exceptional rainfall as a necessary precursor for mouse plagues in southeastern Australia. Long‐term rainfall anomalies interact with ecological processes to reset population dynamics, creating conditions that support rapid mouse population growth following periods of ...

Rapid non‐destructive assessment of leaf water status with low‐cost transmittance meters

Methods in Ecology and Evolution, EarlyView.
Abstract Tools for more efficiently managing agricultural production and the use of limited water resources are required in the context of a growing global population, while the increasing threat posed by droughts and wildfires necessitates improved methods for risk assessment, forecasting and early warning. Quantifying leaf water content is central to

Genome diversity in Triticum aestivum [PDF]

, 2015
The aims of this PhD research are to identify and characterise genome diversity in Triticum aestivum (bread wheat). This research will establish a process for the identification of large numbers of single nucleotide polymorphisms (SNPs) and other genetic variations in Triticum aestivum.

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.
