How Many Ways Can You Count Wolves?
Although radio-collaring is often used to monitor wolf populations, scientists are turning their attention towards methods that do not require live-capture of animals. What are some of these options, and how do they stack up against radio-collaring?

Soft Manatee, Warm Manatee? Understanding How Manatees Behave
Antillean manatees are an endangered subspecies of manatee that live in the warm waters of the Caribbean, but little is known about their behavior, both in the wild and under human care. This is why scientists in France set out to better understand and define manatee behavior in captivity, identifying how bold or shy they were and how they acted towards novel and familiar stimuli.

Aquatic birds play an important role in shallow water ecosystems, affecting the diversity of their prey communities and providing an important link in the food web. Over the years, mortality has increased in many aquatic bird species due to human activity. New research on a population of Greater Scaup (Aythya marila), an aquatic bird species native to Europe, determined that fisheries contribute heavily to its mortality and gives us tools to understand how we can reduce this impact. If no action is taken, this species could become endangered within the next 30 years.
Read MoreThe Endangered Species Act doesn’t protect all habitat equally
Biodiversity loss causes a reduction in ecosystem services, a loss of potential medical substances, and a less secure food supply chain. Habitat loss is the top reason for biodiversity loss as it reduces the size of populations and hinders reproductive success.
