Protecting habitat of species at risk is critical to their recovery, but can be contentious. For example, protecting species that are locally imperilled but globally common is often thought to distract from protecting globally imperilled species. However, such perceived trade-offs are based on the assumption that threatened groups have little spatial overlap, which is rarely quantified.

- Seamounts are vital marine habitats with high species diversity, but they are threatened by human activities and are challenging to protect due to their offshore and shallow characteristics.
- Estimates suggest there are between 10,000 and 60,000 seamounts, with recent studies using improved bathymetry data to update these predictions, highlighting the importance of accurate mapping for marine research.
- A survey in the British Indian Ocean Territory revealed issues with previous predictions, revealing 15 'phantom seamounts' that resulted from misinterpretations of navigational charts, showcasing the need for better data quality; the current estimate now stands at 37,889 seamounts, reflecting an increase from earlier counts.
Article Synopsis
- Many lesser-known carnivore species, like the serval, striped hyaena, and aardwolf, are getting less conservation focus compared to iconic large carnivores, despite facing significant human threats.
- A study in Tanzania used camera traps and spatial modeling to assess population densities of these species across different habitats: Ruaha’s tourist area, miombo woodlands, and a community-run wildlife management area, revealing the miombo woodlands had the highest serval density.
- The findings suggest that factors like precipitation, predator presence, and human impact influence carnivore populations, highlighting the critical need for miombo woodland and community-managed conservation efforts.
A crown-ether dithiol quaterthiophene is synthesized and immobilized on gold surface by double covalent fixation. UV-vis spectroscopy and cyclic voltammetry show that the corresponding dithioester precursor can complex Pb(2+) in solution and that this property is maintained for monolayers of the dithiol on gold. Current-voltage measurements by eutectic GaIn drop contact on the monolayer show a significant increase (up to 1.
