Vegetation structure and plant functional traits in abandoned pastures were more similar to savannas than to the Atlantic Forest.

The density of organisms associated with rhodoliths in the euphotic zone is higher than in the mesophotic zone.

Drivers of macrofauna associated to rhodoliths were depth zone, average diameter, biomass of macroalgae and density of rhodoliths.
- •
The biodiversity associated with the SW Atlantic mesophotic rhodolith beds seems to be much higher as previous works had shown for other rhodolith beds.

Best practice could increase beef production without increasing its impacts.
- •
There are trade-offs between GHG reduction and other impacts.
- •
Interventions in the cow-calf stage have more potential to increase production.
- •
Birds use scattered trees mainly as stepping stones and feeding sites.
- •
Their use as stepping stones depends on tree size and distance to a forest patch.
- •
Bird are able to move greater distances and at higher frequencies across a landscape using stepping stones.
- •
Both forest cover and tree aggregation increase tree visits under predation risk.

We tested the accuracy of biological attributes to predict reef fish species’ vulnerability to extinction.
- •
Megafauna, carnivorous, mobile invertivorous, habitat specialists, highly mobile species and Elasmobranchii have greater extinction risks.
- •
Reef sites along southestern Brazil have greater proportions and richness of threatened species.

Biological attributes may be a tool to predict the vulnerability of reef fishes.
- •
For the first time, we used the tick species Rhipicephalus sanguineus sensu lato (distributed in different areas around the world) to characterize its global geographic distribution using ecological niche modeling, and explore the uncertainty involved in transferring models in space and time.
- •
The global model (the one calibrated in all calibration areas together) predicted broad suitable areas for the species around the world.
- •
Models based on each calibration area separately showed the potential geographic distribution of R. sanguineus sensu lato under current-day conditions with high agreement across the eastern United States, southern Mexico, northern South America, Brazil, Europe, North Africa, sub-Saharan countries, Asia, and Australia.
- •
The global potential distributions of R. sanguineus sensu lato under future conditions were very similar between the two RCPs, but GCMs, model replicates, and model parametrizations contributed importantly to the overall variation detected.
- •
Two geographically partitioned haplotypes reported.
- •
No recent gene flow between islands.
- •
Results indicate good chances of Rata Island remaining rat-free after eradication.
- •
Climate change will affect species distribution via variation in suitable area amount, displacement of optimal conditions, and/or exposure to non-analog conditions.
- •
We found that Amazon primates will face a plethora of effects of climate change on their geographic ranges.
- •
Even in cases that the species range could increase, Amazonian primates will be exposed to novel climates and might not be able to track their preferred environments.
- •
Remaining populations might also become fragmented and are forecasted to occupy sub-optimal conditions at the periphery of their future ranges.
- •
Conservation assessments should consider the multiple dimensions of climate change.
