Unlocking Kenya’s Pyrethrum Potential: A Breeding Review for a Competitive Future

open access: yesAdvances in Agriculture, Volume 2026, Issue 1, 2026.
Pyrethrum (Tanacetum cinerariifolium) is a strategically important industrial crop underpinning the world supply of organic pesticides. Despite Kenya’s past dominance in global pyrethrum production, the genetic improvement of the crop has lagged. This has led to having varieties of low yields, variable pyrethrin content, susceptibility to biotic and ...

Winter Temperature Affects Fatty Acid Composition and Gene Expression, but Not Fat Content and Survival in a Northern Population of a Range‐Expanding Spider

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
This study provides insight into the performance of a range‐expanding species and the physiological and molecular mechanisms underlying thermal tolerance at its expanding edge. ABSTRACT Species expand their geographic distribution when environmental conditions are favorable or when mutations arise that allow them to live in previously unfavorable ...

Entomopathogenic Nematodes Induce Metabolic Reallocation in Maize Roots Without Altering the Performance of Two Root Herbivores, Diabrotica virgifera and Diabrotica balteata

open access: yesPlant, Cell &Environment, Volume 48, Issue 12, Page 8561-8572, December 2025.
ABSTRACT Entomopathogenic nematodes (EPNs) are key biological control agents in agriculture, but their direct effects on plant metabolism and resistance to herbivory remain underexplored. By combining transcriptomic, metabolomic, and herbivore assays, this study aimed at providing a holistic description of maize root responses to EPNs and to assess ...

Invasive giant river prawns as opportunistic, generalist predators in the Amazon Delta: Insights from metabarcoding

open access: yesEcosphere, Volume 16, Issue 11, November 2025.
Abstract Invasive species alter habitats and biological communities. The giant river prawn Macrobrachium rosenbergii (de Man 1879) was introduced to Brazil for aquaculture, and invasive populations have established in the Amazon Delta region where they are believed to pose a risk to the native aquatic fauna.

Hybrid AI Model With CNNs and Vision Transformers for Precision Pest Classification in Crops

open access: yesFood Science &Nutrition, Volume 13, Issue 11, November 2025.
This study proposes a hybrid deep learning model integrating CNNs, attention mechanisms, and Vision Transformers for accurate classification of five major rice crop pests. The model captures both fine‐grained local features and global spatial relationships, achieving a high accuracy of 95% on an augmented dataset.

Nietzsche at the Deathbed: the Eternal Recurrence as a Counter to the ‘Preaching of Death’

open access: yesThe Heythrop Journal, Volume 66, Issue 6, Page 623-640, November 2025.
Abstract In recent scholarship, the dominant reading of Nietzsche’s concept of the eternal recurrence has been as a thought experiment. This paper responds to this in two ways. First, this paper relocates eternal recurrence in the context of Nietzsche’s abiding concern with the ‘preaching of death’, a powerful, life‐negating weapon of the ascetic ...

Metabarcoding Close to Home: Songbird Nests as eDNA Aggregators for Trophic Ecology and Biodiversity Studies

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
We present a novel method for extracting eDNA from whole bird nests and a LNA blocking oligonucleotide designed to reduce metabarcoding reads from nest building sparrows. Metabarcoding of 22 nests from a montane sagebrush steppe ecosystem detected 126 species, primarily insects, including putative diet items, ectoparasites, and confirmed nest predators.

International Biological Flora: Tsuga canadensis*

open access: yesJournal of Ecology, Volume 113, Issue 10, Page 3037-3080, October 2025.
Eastern Hemlock is a long‐lived forest tree of eastern North America known for its deep shade and home given to many organisms. Despite surviving large‐scale clearing for agriculture when Europeans arrived, it returned to dominate when the land was abandoned in the mid 1800s.

Biodiversity in mountain soils above the treeline

open access: yesBiological Reviews, Volume 100, Issue 5, Page 1877-1949, October 2025.
ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...
