In a climate crisis no one is safe, but marine species are getting hit twice as hard

Our world is undergoing a climate crisis, which threatens every living thing on the planet. A study by Pinsky et al. (2019) has found that marine species are more vulnerable to warming than terrestrial species which may change the course of conservation management and deployment of conservation resources.

Melting Moves Marine Mammals

As glaciers melt, the species who live there are faced with a dilemma – retreat into the little remaining habitat or find some way to adapt. Movement data from populations of ringed seals and white whales before and after a major sea-ice decline provides insight on how each species has responded to habitat loss. One of these species has chosen retreat, while the other has learned to adapt.

Can we increase agricultural production without threatening biodiversity?

The world population is expected to reach 9.8 billion by 2050. This increase in population will put pressure on agriculture to produce more food. Many studies have reported that land-use changes, such as cutting down forest to make new farmland, can lead to a loss in the number of species living in an area, known as the biodiversity. It is important to maintain biodiversity because it supports healthy ecosystems and ultimately a healthy planet. A recent analysis of previously published scientific articles suggests that when farming efforts are intensified, agricultural production increases but the number of species supported by the farm decrease. This means that increasing agricultural production comes at a cost.

The Future of Seafood: Integrated Multitrophic Aquaculture

Aquaculture has long been revered as a benefit to the seafood industry by increasing food availability for developing nations and taking pressure off of overexploited wild fish stocks. However, aquaculture has also been cited for its negative environmental impacts. Integrated Multitrophic Aquaculture (IMTA) is a solution that combines species of different trophic levels to be grown together in the same aquaculture setting, reducing environmental impacts and increasing overall production.

Islands and Alleles: How genetics can help protect endangered species

When talking about diversity in the natural world, we often think of the bright colors and bold patterns of fish gliding among a reef, or the variety of flying, creeping, and crawling critters found in the layers of a rainforest canopy. However, diversity even within a single species is an important indicator of a population’s health and stability. This type of diversity can be invisible to us when contained in the form of genes that control which traits organisms possess. In this study, scientists helped us to see the invisible diversity of an endangered skink and learn how to more effectively conserve this diversity.

Hidden fish populations protect us from ourselves!

We raise cows, chickens, and pigs on farms, but we still commonly hunt wild populations for one type of animal protein- seafood. Many fish populations are overexploited, but scientists found that despite this, Atlantic flounder populations were in better shape than expected. Why? How can we ensure that this stability continues?
