Microplastics — small plastic pieces less than 5 millimeters in length — are ubiquitous in the environment, and they can have significant effects on wildlife. A new study reveals that there are multiple impacts of different microplastics — with varying sizes, shapes, and chemical makeup — to the survival, growth, and development of larval fathead minnows, an important prey species in lakes and rivers in North America.
New evidence shows important seabird nutrients reach coral reefs after rat eradication
Scientists have provided the first evidence to show that eradicating rats from tropical islands effects not just the biodiversity on the islands, but also the fragile coral seas that surround them.
Warming seas might also look less colorful to some fish. Here’s why that matters.
Climate change is driving some fish into cooler, deeper waters. Now they may be faced with another challenge: how to make sense of a world drained of color. Duke and Exeter researchers report that even small increases in depth could make it harder for fish to discern the hues they use to find food, friends and family. They are trying to predict which species will be most impacted, and whether they’ll be able to adapt.
Central African forests are unequally vulnerable to global change
An international study coordinated by researchers from IRD and CIRAD reveals the composition of the tropical forests of Central Africa and their vulnerability to the increased pressure from climate change and human activity expected in the coming decades.
