Mangroves keep waves at bay. A new study helps scientists predict how

2 October 2026 at 00:29
Existing at the junction of land and sea, mangrove forests have long been heralded for their ecosystem services, including their ability to buffer coastal areas against storm surges and rising seas. Now, new research has found a way to predict just how much mangroves can diminish waves associated with severe storms. When a wave hits an outcrop of mangroves, its energy is absorbed by the plants’ dense network of twisted roots. When the wave comes out on the other side, its intensity is often decreased, acting as a natural buffer for shorelines — sometimes even shielding shoreside communities from water damage or severe floods. This ability for mangroves to curb wave intensity — a property called attenuation — is well known among scientists. However, much of the data supporting this was collected by measuring mangrove attenuation during mild, calm periods of weather. Quantifying mangrove attenuation during storms or typhoons is trickier — it’s harder to gather data, and there are more factors dominating wave motion, like turbulence. Because of this, “existing models do not always perform so well to predict the wave attenuation by mangroves during storms,” Stijn Temmerman, a professor at the University of Antwerp, Belgium, told Mongabay by video call. This is especially important, researchers told Mongabay, as climate change is linked to severe weather systems. More than 87 million people were impacted by climate-related disasters in 2025, including flooding events and severe storms. Because of this, the development of new methods to model worst-case scenario climate and…This article was originally published on Mongabay

New releases a leap forward for endangered frog in southern California

30 September 2026 at 20:59
Frog release days always start early, at about 4 a.m., so that staff can get up to the site before the day gets too hot, said Erin Lundy, manager of conservation initiatives at the Aquarium of the Pacific in the U.S. The first challenge is catching the frogs. A newly morphed southern mountain yellow-legged frog (Rana muscosa) is about an inch long, fast, and very good at squeezing into cracks, Lundy said. It can take a couple of hours for staff to scoop them all up from the tanks. Lundy prefers grabbing them with gloved hands, though others use nets. The aquarium has been rearing southern mountain yellow-legged frogs since 2021, as part of a multi-agency, 20-plus-year conservation effort for the species, a Southern California amphibian listed as endangered on the IUCN Red List. Head-starting the frogs by ushering them through metamorphosis in captivity boosts their odds of survive, Lundy said. This year’s cohort arrived at the aquarium late last summer as 2-month-old tadpoles from the Los Angeles Zoo, where they were bred. Through winter and into spring, aquarium staff watched as their limbs erupted and tails slowly reabsorbed. By August, most were ready for life in the wild. (Metamorphosis for this species takes from one to five years in the wild, and is highly variable in captivity. Those that did not fully metamorphosize by the release date will be held back and released as larger adults next summer).
