Forest edges buffer effects of agricultural management on bee–plant interaction networks

Ecological Entomology, EarlyView.
Agricultural management effects: Organic and conventional crop margins host similar bee and plant species, but network structure differs: organic farms exhibit higher interaction diversity, conventional farms higher connectance. Role of forest edges: Native forest edges stabilize bee–plant networks by providing continuous floral resources and suitable ...

MATURAÇÃO EM CANA-DE-AÇÚCAR: MANEJO DO SOLO

Colloquium Agrariae, 2010
The research objective was to evaluate the effect of trash deposited in the soil in ratoon sugarcane cultivar RB 86 7515, planted in two different planting systems (furrow and windrow) and who received treatment with hydrogel polymer (0, 4, 8, and 12 grams per meter), in determining the maturity indexes (MI) of sugarcane.

Wood Thrush (Hylocichla mustelina) occupancy patterns reveal sensitivity to low precipitation on nonbreeding grounds in northern Costa Rica

Ibis, EarlyView.
Climatic change and anthropogenic disturbances are reshaping animal populations. Habitat loss and extreme climatic events are particularly strong drivers of declines in species that depend on forested areas. For migratory songbirds, climate and the persistence of suitable habitat over time are fundamental to sustaining populations annually.

DNA barcoding uncovers two putative new species in Trachelyopterus (Siluriformes: Auchenipteridae)

Journal of Fish Biology, EarlyView.
Abstract Trachelyopterus is a cryptic genus within the Neotropical catfish family Auchenipteridae with a complex history of taxonomic revisions. Despite the notable morphological and genetic similarities among its species, some studies suggest that the genus harbours greater diversity than is currently recognized, including additional species yet to be

Molecular phylogenetic analysis sheds light on the diversity and evolutionary history of the Neotropical and African Triplophyllum (Tectariaceae)

Journal of Systematics and Evolution, EarlyView.
We used a molecular approach to resolve the evolutionary lineages of Neotropical Triplophyllum, uncovering that current species circumscriptions are hindered by high morphological homoplasy in indument characters. Our results support the recognition of three new species and provide a necessary neotypification for T.

‘They are not predators: They are a higher power’—Relational values and principles framing human–predator relationship in Noongar Country, Southwestern Australia

People and Nature, Volume 8, Issue 8, Page 2682-2699, August 2026.
Abstract Human–predator coexistence presents urgent conservation challenges that demand approaches extending beyond mere conflict mitigation. Indigenous knowledge systems, though historically marginalised by Western science, offer vital insights into ethical, sustainable relationships with nature.
