Bulk tissue versus amino acid carbon stable isotopes to reveal the diet and basal resource use of an invasive rodent

Ecosphere, Volume 17, Issue 2, February 2026.
Abstract Stable isotope analysis (SIA) is widely used to reconstruct food webs, characterize trophic relationships, and estimate dietary composition. However, bulk tissue SIA (BSIA) can yield imprecise estimates when dietary sources are isotopically similar.

Application of chemometric analysis to infrared spectroscopy for the identification of wood origin [PDF]

, 2016
Chemical characteristics of wood are used in this study for plant taxonomy classification based on the current Angiosperm Phylogeny Group classification (APG III System) for the division, class and subclass of woody plants.

Non-Target Effects of Transgenic Blight-Resistant American Chestnut (Fagales: Fagaceae) on Insect Herbivores [PDF]

Environmental Entomology, 2011
American chestnut [Castanea dentata (Marshall) Borkhausen], a canopy dominant species across wide swaths of eastern North America, was reduced to an understory shrub after introduction of the blight fungus [Cryphonectria parasitica (Murrill) Barr] in the early 1900s.

Winter diet of Korean long‐tailed goral Naemorhedus caudatus: natural foraging and post‐wildfire supplementary feeding revealed by DNA metabarcoding

Wildlife Biology, Volume 2026, Issue 1, January 2026.
Understanding the winter diets of endangered ungulates is critical for developing effective conservation strategies in temperate ecosystems, where seasonal fluctuations significantly affect food availability. The long‐tailed goral Naemorhedus caudatus, an herbivorous ungulate listed as a category I ‘Endangered species' (EN) under the Korean Wildlife ...

Intermittent pollen-tube growth in Fagales, especially in alders(Alms sieboldiana)

PLANT MORPHOLOGY, 2005
Summary: In Fagales, the ovary is still immature when pollen is delivered to the stigma and the fertilization occurs more than one month after pollination. Developmental study of the pollen-tube growth in the pistil of three species(Casuarina equisetifolia, Alnus sieboldiana and Myrica rubra)in Fagales showed that the pollen tube grows intermittently ...

High‐Quality Genome Assembly and Annotation of Ceratonia siliqua Provide Insights Into the Secondary Loss of Symbiotic Nitrogen Fixation

Physiologia Plantarum, Volume 178, Issue 1, January/February 2026.
ABSTRACT The carob tree (Ceratonia siliqua L.), an evergreen legume native to West Asia and long cultivated throughout the Mediterranean basin, is valued for its drought tolerance, nutritious pods, and ecological value. Despite its economic and environmental importance, genomic resources for this species have been limited.

Evidence from multivariate morphometric study of the quercus pubescens complex in southeast Italy [PDF]

, 2016
The name Quercus pubescens s.l. encompasses a complex of deciduous oak taxa with mainly southeastEuropean distribution and a large ecological niche. As the easternmost region of Italy, Apulia is rather isolated from a geographical and physiographical ...

Pond frog as a predator of hornet workers: High tolerance to venomous stings

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Some animals use stingers to repel attackers, and some predators have evolved tolerance to such stings, enabling them to consume venomous prey. For example, social wasps, such as hornets, use modified ovipositors as venomous stingers to inject venom, which can cause intense pain in humans.

Progress and problems in the assessment of flower morphology in higher-level systematics [PDF]

, 2018
Floral features used for characterization of higher-level angiosperm taxa (families, orders, and above) are assessed following a comparison of earlier (precladistic/premolecular) and current classifications.

Stable isotope analysis of ectoparasites as a tool for understanding trophic interactions with mammalian hosts

Medical and Veterinary Entomology, Volume 39, Issue 4, Page 664-674, December 2025.
Ectoparasites showed significant δ15N enrichment compared to their hosts, indicating trophic enrichment, but δ13C preservation varied. Lice, fleas and ticks preserve their hosts' isotopic fingerprints to varying degrees, with lice reflecting host dietary patterns most closely, likely due to their exclusive, host‐specific feeding behaviour. The presence
