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...

Freshwater bivalves are globally distributed, diverse, and common in benthic communities. Many taxa, particularly in the most species‐rich order, Unionida, are declining due to anthropogenic stressors, while a small number of non‐native species have become increasingly abundant and widespread, commonly replacing native bivalve assemblages. To understand how these global changes may impact ecosystems and people, we conducted a...

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...

Species phenology is being altered by ongoing climate changes with yet underappreciated consequences for ecological processes and ecosystem stability. Contrary to what happens with some key life events of flowering plants, comparatively little information exists about fern and lycophyte phenology and how it is affected by the current climatic changes. In part, this stems from the lack of long‐term datasets. Here we provide inf...

The migratory patterns of many Neotropical bird species remain largely unknown. Numerous logistic challenges prevent such studies, from research costs, often prohibitively expensive to Neotropical research institutions, to equipment weight limitations. Therefore, it is paramount to explore new possibilities in the field of migratory bird research such as the abundant records from citizen science platforms. In this study, we in...

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...
