Interspecific hybridization and inbreeding effect in seed from a Eucalyptus grandis x E. urophylla clonal orchard in Brazil

Genetics and Molecular Biology, 1998
We used allozyme markers to estimate the amount of natural hybridization between Eucalyptus grandis and E. urophylla in a 7.4-hectare commercial hybrid-seed orchard planted in Espírito Santo, Brazil.

Carbon Dots as Photoinitiators for Thiol–Ene Reactions

ChemCatChem, Volume 18, Issue 9, 14 May 2026.
A metal‐free and eco‐friendly approach for the anti‐Markovnikov hydrothiolation of olefins, using carbon dots (CDs) as bio‐derived photoinitiators, is presented herein. The procedure occurs in aqueous media upon visible light irradiation, and it is compatible with a broad range of thiols, alkenes, and alkynes.

Dietary Overlap of Sympatric Polyphagous Alpine Grasshoppers Includes Invasive Plant Species

Ecology and Evolution, Volume 16, Issue 5, May 2026.
The diets of three sympatric grasshopper species were compared using mandible morphological analysis, microhistological examination, and DNA metabarcoding of gut contents. Although mandible morphology differed across species and sexes, dietary divergence was not evident.

Meloidogyne spp. in Eucalypts - Reproduction and Damage to Seedling Growth

Journal of Nematology
Eucalypts are cultivated worldwide, but little is known about their status as hosts of root-knot nematodes (RKN) (Meloidogyne spp.). Moreover, information is scarce regarding the nature of the damage caused by RKN to eucalypt seedlings and trees.

Composition and Diversity Characteristics of Gut Microbiota during the Development of Telchinia issoria (Lepidoptera: Nymphalidae)

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Ramie (Boehmeria nivea) is a traditional economic crop of high commercial value, whose cultivation is threatened by the leaf‐feeding pest Telchinia issoria. This study investigated how the gut microbiota of T. issoria shifts across its larval, pupal, and adult stages using 16S rRNA amplicon sequencing. ABSTRACT Ramie (Boehmeria nivea) was a traditional

Danos causados por diferentes níveis de desfolha artificial para simulação do ataque de formigas cortadeiras em Pinus taeda e Eucalyptus grandis

Pesquisa Florestal Brasileira, 2011
A desfolha artificial permite mensurar a intensidade do dano devido à desfolha causada por insetos. No presente estudo, buscou-se avaliar os danos causados por formigas cortadeiras em plantios de Pinus taeda e Eucalyptus grandis com 30 dias de idade. Foi

Optimization of Parsimonious and Synchronized Discharge and Dissolved Organic Carbon Models Across Catchment Scales

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract The production, transport, loss, and export of dissolved organic carbon (DOC) are closely connected with hydrometeorological drivers. While terrestrial production depends on biogeochemical variables like soil moisture, air temperature, and the contact area between water and organic matter sources, export is determined by water availability and

From species lists to interactions: Network structure, not richness, guides seed dispersal management in human‐modified islands

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our findings show that management strategies can create fundamentally different seed dispersal regimes, even under similar environmental conditions. Anthropogenic diversification reshapes network organisation into distinct structural configurations, rather than consistently enhancing overall cohesion.

Feeding ecology of Australian Christmas beetles (Coleoptera: Scarabaeidae: Rutelinae): Implications for conservation and habitat management

Austral Entomology, Volume 65, Issue 2, May 2026.
Abstract Christmas beetles (subfamily Rutelinae, genera Anoplognathus, Calloodes and Repsimus) are an ecologically important and culturally significant group of Australian scarabs, known for their striking appearance and seasonal mass emergences. Over the last decade, anecdotal reports suggest widespread population declines, raising concerns about ...

Strade, ferrovie e grandi rischi

TeMA: Journal of Land Use, Mobility and Environment, 2009
Nell’articolo il rapporto tra sistemi di accessibilità (ferroviaria e stradale) e grandi rischi viene affrontato da due diverse prospettive. La prima vede tali sistemi come esposti e vulnerabili a diverse forme di pericolosità naturale; la seconda li considera invece quali potenziali fonti di pericolo, indagando in particolare il ...
