This case report describes the advanced critical care, surgical management, and one-year outcome of a free-ranging adult male maned wolf ( Chrysocyon brachyurus ) presenting with severe polytrauma and concomitant renal dioctophymosis. The animal was rescued with a severely contaminated open tibial fracture associated with extensive soft tissue necrosis and active myiasis, rendering limb-sparing procedures unfeasible. A high pe...
The supply of metabolizable nutrients to suckling beef calves on pasture can improve their performance, increasing weaning weight and productivity in cow–calf systems. The objective was to evaluate the effects of dried distillers grains (DDG) inclusion on intake, digestibility, metabolism, and performance of suckling beef calves grazing tropical pastures. Forty-eight Nellore calves, 120 ± 35 days of age and 135 ± 23.4 kg of bo...
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...
Morphological evidence suggests that European Middle Pleistocene hominins share a common phylogenetic history, yet they display a substantial morphometric variability. In particular, MIS 7 − 5 hominins have been proposed to exhibit a distinctive combination of traits differentiating them from both earlier and later Neanderthal populations. However, the scarcity of fossil remains from this period limits our understanding of Nea...
Nutritional and metabolic responses of sheep fed banana leaf hay treated with sodium hydroxideNARA Subscribed
Our objective was to evaluate the impacts of the treatment of banana leaf hay with levels of sodium hydroxide (NaOH) on intake, digestibility, feeding behavior, and blood parameters of sheep. Five ½ Santa Ines × Dorper sheep with body weight of 38.43 ± 4.38 kg were used in a Latin square design. Treatments were based on levels of NaOH in banana leaf hay, as follows: 0; 1.25; 2.5; 3.75 and 5%. Overall, the intakes of dry matter...
Main conclusion Virus-like particles (VLP) from hepatitis C virus were successfully produced in Nicotiana benthamiana plants for the first time, by co-expressing three viral proteins (Core, E1 and E2) in a polycistron-like arrangement. Abstract Hepatitis C virus (HCV) remains a global health challenge, underscoring the need for a preventive vaccine. Virus-like particles (VLP) offer a safe alternative, as they resemble native v...
Corn oil-formulated Cordyceps javanica: a high-performance, low-impact tool for integrated tick managementNARA Subscribed
Mycoacaricides represent a promising alternative for managing resistant tick populations. This study evaluated the efficacy of corn oil–based Cordyceps javanica formulations against non-parasitic stages the southern cattle tick Rhipicephalus microplus under laboratory and semi-field conditions. Additionally, fungal persistence in soil and possible alterations in soil composition were assessed using ATR-FTIR spectroscopy combin...
Use of willow (Salix sp) biomass as tree fodder: nutritional value and conservation methodsNARA Subscribed
This study evaluated the nutritional value and different methods of conservation of two willow materials—the hybrid clone Terra Nova (HTN) from a short‑rotation coppice (SRC) system and the native Salix atrocinerea (SAT) from riparian stand—representing contrasting willow resources available in the study region. The leaf fraction (LE)—although representing 5.0 in untreated silages). Willow leaf silages achieved CP levels of 18...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
