Science

New research suggests that seals evolved the ability to hear efficiently in both aquatic and terrestrial environments around 26 million years ago.

Researchers comparing fish populations from naturally heated geothermal pools with those from cooler waters have found that prolonged exposure to higher temperatures can lead to lasting trait changes that may improve species’ ability to cope with climate warming.

Tracking data has revealed that young great white sharks can rapidly respond to extreme weather, leaving their nursery areas when storm-driven cooling changes ocean conditions.

Fisheries

Scientists have found that heavy fishing pressure may be causing molecular changes in pearly razorfish populations.

Brazil’s decision to classify tambaqui as a threatened species has prompted fishers and conservation groups to look for practical ways to protect them.

Public consultations have opened on new fisheries management plans for the Irish Sea.

A new agreement in Indonesia is set to enhance protections for fishing workers by promoting safer workplaces, fairer treatment and improved standards for crews at sea.

Marine Protection

Conservationists are raising concerns that planned updates to Ontario’s species protection laws could weaken safeguards for threatened wildlife and affect efforts to preserve biodiversity.

Scientists are urging countries to address the overlooked international trade in sawfish teeth, which could pose an additional threat to already endangered sawfish populations.

An ICES review has highlighted ongoing challenges for Atlantic salmon, with falling numbers across their range reinforcing the importance of continued efforts to protect and restore populations.

Conservation

A scientist in Ghana is leading efforts to prevent the loss of guitarfish by combining research, community engagement and conservation initiatives to safeguard this threatened marine species.

Researchers found that long-lasting “forever chemicals” accumulate in dolphins as they age, raising concerns about the effects of these pollutants on marine mammals over time.

As heatwaves reduce river flows across France, freshwater fish are facing increasing pressure from warmer, shallower waters, prompting conservation efforts to protect vulnerable populations from the effects of climate change.

The MMO is expanding measures to help protect seahorse populations, with a focus on reducing threats and supporting the conservation of the habitats these species rely on.

Climate Crisis

Tensions have grown over the treatment of scientists under the Trump administration.

New UK Prime Minister Andy Burnham has said the country “cannot ignore” the role of North Sea oil.
