Why is it important to do research at seal rehabilitation centers?

For many animal lovers, working as a seal rehabilitator seems like a dream job. You spend all day taking care of baby seals and release them when they’re strong enough to live on their own. But have these types of rehabilitation centers done enough research on what makes a seal ready for release? Could the time spent in rehabilitation cause the seals future problems or make it harder for them to survive in the wild? If so, should we stop seal rehabilitation all together?

Bugmeal: The Future of Aquaculture?

With global declines in wild fish stocks, there is an increasing demand for fish grown through aquaculture. Yet current diets for aquaculture fish are mostly made of fish sourced from wild fisheries and from the aquaculture industry itself (Péron et al., 2010), contributing to unsustainable practices in the industry. In an effort to find a more sustainable replacement, researchers at the Japan International Research Center for Agricultural Sciences conducted a study looking at the effects of substituting fish protein used in fish diets with protein made from the younger stages of the black soldier fly. The results look promising.

The Unintended Catch: Population Declines in Greater Scaup due to Fishery Bycatch

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.

These Boots Were Made from Exotic Leather

When picturing an American cowboy, images of horses and lassos come to mind, studded in spurs and blanketed in leather. The leather that you imagine is most likely cow hide, tanned and sourced in the United States of America. However, this mental image may require some adjustment. According to a study conducted by Jessica Heinrich and her team, exotic leather within the US is relatively common, particularly leather sourced from scaled mammals known as pangolins and large fish known as arapaima. Conservation efforts are more dire than ever as illegal trade of the two scaly organisms continues.

Turtle Hatch Rates Skyrocket after Incubation

Sea turtles are often seen as a “poster-child” animal for conservation efforts in coastal areas. Beaches are covered with signs, and local groups search every night for mothers’ nests so they can put up protective barriers and increase the hatching success. However, for other species of turtles, like the freshwater spiny softshell turtles (Apalone spinifera), simple protection of the nests are not currently an effective way to increase hatching success. Instead, researchers have found incubating the eggs of spiny softshell turtles more than doubled the hatching success rate, which may help save this endangered population in Québec, Canada.

Mislabeling Mayhem: Traces of Endangered Shark Species Found in Pet Food and Make-up

There’s power behind every purchase we make. Companies make and sell products based on consumer demand, and we as consumers have a right to know what we are putting our dollars behind. Recently, a study has identified trace levels of threatened shark species in various pet food and cosmetic brands. While this alone is troubling, what’s more concerning is that these products have failed to include shark products on the ingredient label.

T.G.I…M.? Why Wildlife Wants Your Vacation to End Sooner

When the workweek ends and the weekend arrives, many people leave their office life to visit the great outdoors. From birdwatching to biking, spending time in nature may be a positive experience for you, but your presence may make the animals living in the natural spaces you visit on the weekend wish it was Monday already.

The Sound of Silence: Consequences of Man-made Noise on Humpback Whale Songs

Male humpback whales sing loudly and for long durations during breeding season. A hundred years ago their voices did not have to compete with much man-made noise. These days they contend with underwater drilling, sonar, and the noise of thousands of cargo and passenger ships. This affects how and when they sing. The consequences of these changes are still largely unknown.

The value of a species: the whooping crane conservation paradox

The endangered whooping crane is one of the world’s rarest species, with only around 600 individuals, including one wild self-sustaining population (French et al., 2018). Reintroduced populations have had limited success, largely due to low hatching success. One multi-year study demonstrates the role that some endemic species of black flies play in Whooping crane nest desertion. This work also illustrates how conservation approaches should evaluate trade-offs and utilize a decision-analysis framework to construct management strategies that incorporate the needs of all endemic species, rather than pining the value of one species above the other.
