Corals Recover Faster on Artificial Structures than on Natural Reefs

“To better understand how to help corals become more resilient, researchers in Japan studied how quickly corals return to artificial structures compared to natural reefs after bleaching.

Previous studies have explored the same question, typically over one to 10 years. The Japanese study used 29 years of field data.

Using government data, the researchers compared coral cover on vertical breakwaters — grooved structures built to protect the shore from waves — with coral recovery on natural reefs in Naha Port, Japan, from 1989 to 2018.

A bleaching event in 1998 affected both types of substrates, but ‘corals on artificial structures recovered faster from [the] mass bleaching event than the natural coral reef ecosystems,’ Toko Tanaya, lead author of the study and senior researcher with the Port and Airport Research Institute in Japan, told Mongabay in a phone call.

Within six years, the breakwaters recovered to near pre-bleaching levels, while ‘the coral cover on natural reefs barely recovered from bleaching,’ the authors write.”

City Life Is Nudging Raccoons Toward Domestication

“Raccoons living wild in cities in the United States are beginning to show physical changes that resemble early signs of domestication, according to a recent study.

The study found that urban raccoons had developed shorter snouts than rural raccoons, with the research produced by the University of Arkansas at Little Rock and published in Frontiers in Zoology. This is an example of a physical trait that appears across domesticated animals that have adapted to living in close proximity to humans over long periods of time, along with other traits such as smaller teeth, curlier tails, smaller brains and floppier ears.”

Palau Ground Doves Recovering After Conservation Effort

“Seabirds, the IUCN Endangered Palau Ground Dove (Pampusana canifrons), and other native species have significantly increased in number thanks to a successful restoration campaign on Ulong Island, Republic of Palau in the Western Pacific Ocean. 

Island Conservation, the Koror State Government, the Koror State Department of Conservation and Law Enforcement (DCLE), and the Koror State Rangers worked together in 2023-2024 to remove introduced, damaging invasive rats which devoured native bird eggs and young, decimated native plant populations through seed predation, preyed on native crabs, and disrupted food webs—ultimately threatening ecosystem collapse.  

Now, after one full year of rigorous monitoring—including trail cameras, eDNA sampling, and field surveys—the partners confirmed no invasive rodents remain on the island. This success marks a monumental step forward for conservation in Palau, the Micronesia region, and across the Pacific.

With the pressure of invasive species removed, signs of recovery in this unique ecosystem are already emerging. Island Conservation’s monitoring team noticed a higher incidence of Ground Doves, including sightings of chicks at landing sites where they were never previously recorded.”

A New Jaguar Spotted in Arizona Points to Recovery Progress

“The spots gave it away. Just like a human fingerprint, the rosette pattern on each jaguar is unique so researchers knew they had a new animal on their hands after reviewing images captured by a remote camera in southern Arizona.

The University of Arizona Wild Cat Research and Conservation Center says it’s the fifth big cat over the last 15 years to be spotted in the area after crossing the U.S.-Mexico border. The animal was captured by the camera as it visited a watering hole in November, its distinctive spots setting it apart from previous sightings…

As an indicator species, Malusa said the continued presence of big cats in the region suggests a healthy landscape.”

A Bright Spot for Turtles: Olive Ridleys Are Recovering in India

“Kartik Shanker, a leading Indian sea turtle expert and author of From Soup to Superstar, says around 20 years ago, conservationists counted no more than 100,000 turtle nests across the country…

‘But when some measure of protection was put in place,’ he says, ‘these turtles, olive ridley turtles, have rebounded.’ During the past winter’s nesting season, he says conservationists counted ‘about a million nests, which is crazy high.'”
