Anthropogenic habitat transformation has led to population declines and increasing isolation of populations of many species, particularly top predators, where small and fragmented populations often experience limited dispersal and reduced genetic diversity. Jaguars ( Panthera onca ), for example, have lost half of their historical range and most populations outside the Amazon biome are small, isolated and highly threatened. He...

This 2 × 2 factorial study evaluated different progesterone treatment durations and porcine follicle-stimulating hormone (pFSH) presentations for superovulation in acyclic Toggenburg goats. Goats ( n = 56) received short (six days, G6) and long-term (17 days, G17) progesterone intravaginal devices combined with 133 mg (G6 133mg and G17 133mg ) or 250 IU of pFSH (G6 250IU and G17 250IU ) administered in six decreasing doses fro...

In continental shelves of tropical areas, ecological studies on meiofauna are scarce and most studies were mainly based on a single sampling event or limited spatial design. Along the Potiguar Basin continental shelf, carbonate sediments, produced by calcareous algae (rhodoliths) and corals, dominate. The ecology of rhodolith beds has been the subject of relatively few studies despite this ecosystem being under strong pressure...

Motivation Freshwater ecosystems have been heavily impacted by land‐use changes, but data syntheses on these impacts are still limited. Here, we compiled a global database encompassing 241 studies with species abundance data (from multiple biological groups and geographic locations) across sites with different land‐use categories. This compilation will be useful for addressing questions regarding land‐use change and its impact...

Coxiella burnetii is the etiologic agent of Q fever, a worldwide zoonosis. Cattle, sheep and goats are considered the main reservoirs of the disease. Transmission to humans occurs mainly through the inhalation of infectious aerosols from milk, faeces, urine, and birth products from infected ruminants. In this study, a 2-year longitudinal approach was performed to ascertain the excretion of C. burnetii in bulk tank milk samples...
