How coral reefs can survive climate change      (via sciencedaily.com)     Original source 

Similar to the expeditions of a hundred or two hundred years ago, the Tara Pacific expedition lasted over two years. The goal: to research the conditions for life and survival of corals. The ship crossed the entire Pacific Ocean, assembling the largest genetic inventory conducted in any marine system to date. The team's 70 scientists from eight countries took around 58,000 samples from the hundred coral reefs studied.

Global analysis on pollinators in cities: Wild bees and butterflies are at particular risk      (via sciencedaily.com)     Original source 

Butterflies are being hit hardest by urban growth. Shrinking habitats and food availability are causing their populations to decline. The same applies to many wild bees that fly early in spring. According to a new study, pollination has not yet been impacted by this because honeybees, for example, can compensate for the reduction of urban pollinators. The study is the first comprehensive analysis of the subject and includes data from 133 studies. The results underline the importance of nature conservation measures in urban areas.

Conservation policies risk damaging global biodiversity, researchers argue      (via sciencedaily.com)     Original source 

Rewilding, organic farming and the 'nature friendly farming' measures included in some government conservation policies risk worsening the global biodiversity crisis by reducing how much food is produced in a region, driving up food imports and increasing environmental damage overseas.

Caribbean seagrasses provide services worth $255B annually, including vast carbon storage, study shows      (via sciencedaily.com)     Original source 

Caribbean seagrasses provide about $255 billion in services to society annually, including $88.3 billion in carbon storage, according to a new study. The study has put a dollar value on the many services -- from storm protection to fish habitat to carbon storage -- provided by seagrasses across the Caribbean, which holds up to half the world's seagrass meadows by surface area and contains about one-third of the carbon stored in seagrasses worldwide.

Cryo conservation: A cool solution to saving species from extinction      (via sciencedaily.com)     Original source 

In the face of the biodiversity crisis, and alarming data showing a 69% decline in global animal populations since 1970, researchers are banking on a cool solution to help save species from extinction. Much like egg-freezing is used to preserve human fertility options for a later date, the cryo-freezing of genetic samples taken from animals may play an essential role in curbing species extinctions. A new study sheds light on the immense potential of living cell banks, also known as cryobanks, to contribute to global conservation priorities.

Lost giants: New study reveals the abundance decline of African megafauna      (via sciencedaily.com)     Original source 

A groundbreaking new paper focuses on the size and abundance of living and fossil African large mammals, shedding light on the ecological dynamics behind the decline of these iconic creatures. The findings challenge previous assumptions about the causes of megafaunal extinctions in Africa and provide new insights into the restructuring of ecosystems over millions of years.

Team finds reliable predictor of plant species persistence, coexistence      (via sciencedaily.com)     Original source 

Ecological scientists have long sought ways to measure and predict how specific plant communities will fare over time. Which species in a diverse population will persist and coexist? Which will decline? What factors might contribute to continuing biodiversity? Researchers report on a new method for determining whether pairs or groups of plant species are likely to coexist over time.

Older trees accumulate more mutations than their younger counterparts      (via sciencedaily.com)     Original source 

A study of the relationship between the growth rate of tropical trees and the frequency of genetic mutations they accumulate suggests that older, long-lived trees play a greater role in generating and maintaining genetic diversity than short-lived trees.

Whales not to be counted on as 'climate savers'      (via sciencedaily.com)     Original source 

Do whales increase the removal of carbon from the atmosphere? Despite some hope that this would be the case, a new study has found the amount of potential carbon capture by whales is too little to meaningfully alter the course of climate change. The team found the amount potentially sequestered by the whales was too minimal to make significant impact on the trajectory of climate change.
