Transposable Elements as a Source of Novel Repetitive DNA in the Eukaryote Genome

open access: yesCells, 2022
The impact of transposable elements (TEs) on the evolution of the eukaryote genome has been observed in a number of biological processes, such as the recruitment of the host’s gene expression network or the rearrangement of genome structure. However, TEs

Taxonomic and functional diversity of urban bees of the world

open access: yesConservation Biology, EarlyView.
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Marcador de DNA mitocondrial para estudos genético-populacionais de Tartaruga-da-amazônia (Podocnemis expansa Schweigger, 1812)

open access: yesBiodiversidade Brasileira, 2022
Os quelônios são animais de vida longa e poucos dos seus indivíduos chegam à fase adulta. Além da baixa taxa natural de recrutamento, diversas ações antrópicas vêm dificultando a manutenção das populações desse grupo.

Which One Tastes Better? Testing Distinct Baits to Evaluate Fruit‐Feeding Butterfly Assemblages (Lepidoptera: Nymphalidae) in a Subtropical Region

open access: yesAustral Entomology, Volume 65, Issue 4, November 2026.
ABSTRACT Standardised sampling protocols are essential for improving biodiversity assessments, particularly for indicator groups such as fruit‐feeding butterflies. Although fermented banana is the most widely used bait in tropical regions, rotten fish is the best bait for catching fruit‐feeding butterflies in high‐altitude sites.

Potential Range Shifts of Exotic Plants: Insights From a Mining‐Affected River Basin in Southeast Brazil

open access: yesBiotropica, Volume 58, Issue 6, November 2026.
ABSTRACT The concurrent effects of climate change and anthropogenic disturbances, such as mining disasters, can significantly influence the distribution of exotic plant species, either by reducing climatic suitability for some taxa or by creating disturbed conditions that favor their establishment and spread.

Urbanization and food transition in the Brazilian Amazon: From wild to domesticated meat

open access: yesPeople and Nature, Volume 8, Issue 10, Page 3236-3249, October 2026.
Abstract Urbanization is expected to influence food transitions, resulting in a shift from wild foods to more domesticated foods. Concomitantly, food insecurity and urban demand for natural resources, including wildlife, are expected to increase overall, even when the per capita consumption is expected to decrease.
