The manned wolf ( Chrysocyon brachyurus ) has a highly diversified diet, that includes fish and amphibians, which may harbor infective forms of parasites, such as Dioctophyma renale and Pearsonema (syn. Capillaria ) spp. Both parasites affect the urinary tract of their hosts, with D. renale being capable of infecting a wide range of mammalian species, whereas Pearsonema spp. exclusively parasitizes wild and domestic canids and...

Nutrition is a key determinant of performance, carcass traits, and production efficiency in beef cattle. In this context, feed additives have emerged as a promising strategy to enhance nutrient utilization and reduce production costs. We aimed to evaluate the effects of replacing urea with a product extruded urea enriched with essential oils (NFeed ® ) on nutrient intake, performance, blood parameters, and feed cost in feedlot...

Edaphic attributes strongly influence sugarcane yield, yet production environments are commonly classified based on average productivity, which may not fully capture environmental variability. This study evaluated how physicochemical soil attributes and soil classes influence sugarcane productivity and whether integrating nonlinear modeling and multivariate analyses improves the characterization of production environments. Eda...

Primates can share parasites with humans, and understanding host-parasite interactions is essential for evaluating the condition of wild primates, ecological dynamics, and One Health interface, which integrates humans, animal, and environmental health in shared environments. One example is filarial nematodes of the genus Mansonella , for which a lack of in-depth studies of symptoms or blood alterations limits our understanding...

Brazil is among the world’s leading avocado producers, with cultivation increasingly threatened by gall-inducing midges that damage blossoms and impair fruit development. During surveys in commercial Hass avocado orchards in Minas Gerais, Brazil, a previously unknown species of Bruggmanniella Tavares, 1909 (Diptera: Cecidomyiidae) was discovered infesting young fruits. Here, we describe Bruggmanniella abacate sp. nov. Garcia a...

This study evaluated lignocellulosic residues as low-cost adsorbents for CO 2 capture in a dynamic column system, focusing on spent coffee grounds biochar (SCGB) as an alternative to commercial activated carbon. Commercial activated carbon, SCGB, magnetized SCGB, KOH-activated SCGB, peanut shell pellet charcoal, sugarcane bagasse charcoal containing kaolin, and calcined SCGB samples were tested. SCGB was produced by pyrolysis...

We used acoustic telemetry to investigate the nursery habitat use of 33 juvenile meagre Argyrosomus regius (mean size = 581 ± 105.1 mm), recording more than 60,000 detections in the Tagus estuary, located in the North-Eastern Atlantic. All individuals used the nursery area from spring to autumn, and a small number (22.2%) remained in the Tagus estuary during winter. Daily movements averaged 6.2 ± 1.9 km, with maximum daily dis...

Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...

This study evaluated the effects of increasing inclusion levels of biological silage produced from tambaqui ( Colossoma macropomum ) by-products (BST) in diets of commercial hens at different ages. A completely randomized design in a 2 × 5 factorial arrangement was adopted, comprising two hen ages (23 and 83 weeks) and five BST inclusion levels (0, 1, 2, 3, and 4%), with four replicates of six birds per treatment. Moderate BST...

Aim To reconstruct the historical biogeography and diversification dynamics of the fern family Gleicheniaceae, testing whether (1) its main centres of diversity are the result of within‐area speciation or lineage immigration, (2) dispersal shows directionality across tropical regions and (3) shifts in geographic distribution are correlated with diversification rates. Location Tropical and subtropical regions worldwide, with a...
