Repeated trends in altitudinal gradients of diversity: How habitat filtering and biotic interactions structure ecological communities

Journal of Animal Ecology, EarlyView.
This study reveals that tropical butterfly communities show remarkably consistent elevational patterns of diversity and phylogenetic structure across regions with contrasting evolutionary histories, demonstrating how regional species pools and local ecological factors jointly shape biodiversity along altitudinal gradients.

Evaluation of the Bioactive Compounds of Apis mellifera Honey Obtained from the Açai (Euterpe oleracea) Floral Nectar

Molecules
The biodiversity of Brazil provides an excellent climate and favorable pollination conditions for Apis mellifera L., especially in the Eastern Amazon region, which boasts vast floral wealth, including an abundance of açaí (Euterpe oleracea) flowers and ...

Revisiting the Political Economy of Agriculture in 21st Century Food Systems

Journal of Agricultural Economics, EarlyView.
ABSTRACT In 1932, Joseph Duncan argued in the Journal of Agricultural Economics that agricultural economists should engage more explicitly with politics. Nearly a century later, the political economy of food and agriculture has expanded in both scope and complexity.

Availability of a Keystone Plant Resource Reduces Niche Overlap and Drives Distinct Species‐Specific Changes in Niche Breadth Among Small Rodents

Integrative Zoology, EarlyView.
We investigated how three rodent species respond to the seasonal availability of Araucaria angustifolia seeds. While Oligoryzomys spp. increased seed consumption and abundance during seed production, the more insectivorous Akodon paranaensis maintained a broader diet.

Species Distribution Models Reveal the Resilience of Protected Areas for Conserving an Endemic Amazonian Canid

Animal Conservation, EarlyView.
This graphical abstract illustrates the impacts of climate change on the distribution of the Amazon‐endemic canid Atelocynus microtis, highlighting projected habitat loss under future scenarios (SSP2–4.5 and SSP5–8.5). Despite substantial reductions in suitable habitat, a significant proportion remains within Protected Areas, emphasizing their critical

Integrating Aquaponics with Macrobrachium amazonicum (Palaemonidae: Decapoda) Cultivation for the Production of Microgreens: A Sustainable Approach

AgriEngineering
The use of aquaponic systems has grown in recent years, but few of these systems have integrated the production of prawns and short-cycle vegetables. This study evaluated the potential for producing microgreens (beet, amaranth, arugula, and red cabbage ...

Understanding Mammalian Habitat Use With a Multi‐Species, Multi‐Scale Approach: The Jaguar Protection Corridor in Guaviare, Colombia

Animal Conservation, EarlyView.
We applied a multi‐scale, multi‐species framework to quantify how landscape structure and human infrastructure influence habitat use across a terrestrial mammal community within a biological corridor in the Colombian Amazon. Forest cover and spatial configuration influenced wildlife habitat use at spatial scales associated with species dispersal ...

Psychedelic‐assisted treatment for substance use disorder: A narrative systematic review

Addiction, EarlyView.
Abstract Background and aims This is the first systematic review of the extant literature on all major psychedelic‐assisted treatment for alcohol use disorder (AUD), tobacco use disorder (TUD) and other substance use disorders (SUD). We aimed to summarise the evidence for efficacy of psychedelic‐assisted treatment for AUD, TUD, and SUD; to evaluate its

Tall tower observations of a northward surging gust front in central Amazon and its role in the mesoscale transport of carbon dioxide

Meteorological Applications
High‐frequency measurements obtained at two micrometeorological towers are investigated for a rare northward surging gust front that impacted the Amazon Tall Tower Observatory (ATTO), in central Amazon. The gust front originated from a decaying mesoscale
