Rhodococcus equi is an important bacterium that affects foals up to six months of age, especially those that are immunocompromised. The main manifestation is pyogranulomatous pneumonia; nevertheless, extrapulmonary lesions have not only been reported, but are not uncommon, including arthritis and osteomyelitis. Despite the widespread occurrence of rhodococcosis, the macro- and microscopic lesions in the musculoskeletal system...

Metal contamination, particularly by copper (Cu) and lead (Pb), is a persistent environmental threat, yet the adaptive responses of Neotropical bryophytes to such stressors remain largely unexplored. This study evaluated biomass production, photosynthetic performance, and metal accumulation in two native Brazilian mosses ( Campylopus savannarum (Müll.Hal.) Mitt. and Polytrichum juniperinum Willd. ex Hedw.) exposed to increasin...

Beef and dairy production from cattle farming operate under two main systems: feedlot and pasture based systems, both of which are potentially associated with deforestation due to feed-crop cultivation and pasture expansion. Poor pasture management and ongoing land conversion further exacerbate environmental degradation, posing a significant global conservation challenge. Agricultural innovations such as silvopastoral systems...

Chironius laurenti was described based on 27 specimens from localities of the Beni savanna and Chiquitano Dry Forest in Bolivia and one specimen from the Brazilian Cerrado. We examined the holotype of C. laurenti from the department of Beni, Bolivia, as well as most of the paratypes and expanded sample obtained in zoological collections. Based on morphological and molecular data, we restrict the name C. laurenti to the populat...

Drought is a major constraint to plant growth and productivity, and rising atmospheric CO₂ concentrations are expected to modify plant responses to water limitation. However, how CO₂ enrichment reshapes the physiological, metabolic, and molecular regulation of specialized metabolite production under drought remains poorly understood. Here, we investigated the combined effects of elevated CO₂ (e[CO₂]) and drought on plant morph...
