Rays of the family Rhinopteridae Jordan & Evermann, 1896 are highly migratory and widely distributed in warm tropical and temperate waters. Along the Brazilian coast, the presence of two species has been recorded: Rhinoptera bonasus Mitchill, 1815 and Rhinoptera brasiliensis Müller, 1836. These stingrays are commonly caught as bycatch in trawl fisheries, however, the two species lack distinctive external morphological features...
Biochar-driven shifts in the soil bacterial community structure of degraded semiarid soilsNARA Subscribed
Low biochar rates (5 Mg ha −1 ) increased bacterial richness and diversity in degraded soil. Biochar origin controlled microbial assembly and niche specialization patterns. Sewage-sludge biochar favored stress-tolerant and metal-adapted bacterial taxa. Cashew bagasse biochar enhanced nitrogen cycling and chemoheterotrophic functions. Network complexity peaked at intermediate biochar doses and declined at high rates. Biochar ha...
This study evaluated the effects of providing 3–15 kg of a soluble and biodegradable biopolymer-based enrichment material (blend of biodegradable polymers and natural fibers) to prepartum sows housed in farrowing crates. Fifteen sows were blocked by body weight and backfat thickness and assigned to three treatments: no enrichment material (CONT), 3 kg of enrichment material (BN3), or 15 kg of enrichment material with added nut...
