|Our oceans are suffering, but we can rebuild marine life|
It's not too late to rescue global marine life, according to a study outlining the steps needed for marine ecosystems to recover from damage by 2050. The study found many components of marine ecosystems could be rebuilt if we try harder to address the causes of their decline.

Six decades of change in plankton communities
New research shows that some species have experienced a 75% population decrease in the past 60 years, while others are more than twice as abundant due to rises in sea surface temperatures.

Fish have diverse, distinct gut microbiomes
The rich biodiversity of coral reefs even extends to microbial communities within fish, according to new research. The study reports that several important grazing fish on Caribbean coral reefs each harbor a distinct microbial community within their guts, revealing a new perspective on reef ecology.

Traces of ancient rainforest in Antarctica point to a warmer prehistoric world
Researchers have found evidence of rainforests near the South Pole 90 million years ago, suggesting the climate was exceptionally warm at the time.

About the distribution of biodiversity on our planet
Large open-water fish predators such as tunas or sharks hunt for prey more intensively in the temperate zone than near the equator. With this result, a study is challenging a long-standing explanation for the distribution of biodiversity on our planet.

Surprising hearing talents in cormorants
The great cormorant has more sensitive hearing under water than in air. This new knowledge may help protect vulnerable bird species.

Animal camouflage: Natural light flicker can help prevent detection
Movement breaks camouflage, making it risky for anything trying to hide. New research has shown that dynamic features common in many natural habitats, such as moving light patterns, can reduce being located when moving.

Sturgeon genome sequenced
Sturgeons lived on earth already 300 million years ago and yet their external appearance seems to have undergone very little change. A team of researchers has now succeeded in sequencing their genome, delivering a missing piece of the puzzle essential to understanding the ancestry of vertebrates.

In Earth's largest extinction, land animal die-offs began long before marine extinction
Because of poor dates for land fossils laid down before and after the mass extinction at the end of the Permian, paleontologists assumed that the terrestrial extinctions from Gondwana occurred at the same time as the better-documented marine extinctions. But a new study provides more precise dates for South African fossils and points to a long, perhaps 400,000-year period of extinction on land before the rapid marine extinction 252 million years ago.

Scientists predict the size of plastics animals can eat
A team of scientists has, for the first time, developed a way of predicting the size of plastics different animals are likely to ingest.

Animals keep viruses in the sea in balance
A variety of sea animals can take up virus particles while filtering seawater for oxygen and food. Sponges are particularly efficient.

Coral tells own tale about El Niño's past
Scientists use data from ancient coral to build a record of temperatures in the tropical Pacific Ocean over the last millennium. The data question previous links between volcanic eruptions and El Niño events.

Neanderthals ate mussels, fish, and seals too
Over 80,000 years ago, Neanderthals fed themselves on mussels, fish and other marine life. The first evidence has been found by an international team in the cave of Figueira Brava in Portugal. The excavated layers date from 86,000 to 106,000 years ago, the period when Neanderthals settled in Europe. Sourcing food from the sea at that time had only been attributed to anatomically modern humans in Africa.

What can be learned from the microbes on a turtle's shell?
Researchers have found that a unique type of algae, usually only seen on the shells of turtles, affects the surrounding microbial communities. It is hoped that these findings can be applied to support the conservation of turtles. Previous research has shown that a diverse microbiome can protect animals against infections.

Researchers document seasonal migration in deep-sea
For the first time, researchers have documented seasonal migrations of fishes across the deep seafloor, revealing an important insight that will further scientific understanding of the nature of our planet.

As the ocean warms, marine species relocate toward the poles
Since pre-industrial times, the world's oceans have warmed by an average of one degree Celsius (1°C). Now researchers report that those rising temperatures have led to widespread changes in the population sizes of marine species. The researchers found a general pattern of species having increasing numbers on their poleward sides and losses toward the equator.

A small forage fish should command greater notice, researchers say
A slender little fish called the sand lance plays a big role as 'a quintessential forage fish' for puffins, terns and other seabirds, humpback whales and other marine mammals, and even bigger fish such as Atlantic sturgeon, cod and bluefin tuna in the Gulf of Maine and northwest Atlantic Ocean. But scientists say right now they know far too little about its biology and populations to inform 'relevant management, climate adaptation and conservation efforts.'

Plants and animals aren't so different when it comes to climate
A new study reveals that plants and animals are remarkably similar in their responses to changing environmental conditions across the globe, which may help explain how they are distributed today and how they will respond to climate change in the future.

Christmas Island discovery redraws map of life
The world's animal distribution map will need to be redrawn and textbooks updated, after researchers discovered the existence of 'Australian' species on Christmas Island. The finding revises the long-held understanding of the location of one of biology and geography's most significant barriers - the Wallace line.
