● Integrated grain cropping systems promote soil health (SH) and sustainability. ● Microbial biomass and activity (MBA) and community structure (MCS) are key to SH. ● Integration of maize with Urochloa pastures strongly impacts MBA and MCS. ● MBA is more sensitive than MCS to&...

This study aimed to estimate two reproductive efficiency indices in sheep based on the ratio between litter weight (at birth and weaning) and dam weight, as well as their genetic parameters. Phenotypic and pedigree data comprising the period from 1990 to 2018 were obtained fro...

Understanding the effects of environmental parameters on the reproductive cycle of shellfish is an essential tool for successful hatchery conditioning management and, consequently, for seed supply to the industry. For the tropical oyster, Crassostrea tulipa, little is known about the factors ...

This study evaluated relationships among reproductive parameters and the bioclimatic indices: temperature and humidity index (THI), equivalent temperature index (ETI), black globe temperature and humidity index (BGTHI), and thermalv comfort index (TCI), during the frst 45 days of spermatogenesis (SP-4...
