Great to see the huge “Status & Trends of Caribbean Coral Reefs 1970-2024” out, and very pleased to have made major contributions to the Honduras chapter. Overall the findings of the report are very alarming, indicating severe declines in Caribbean reef health: gcrmn.net/caribbean-20...

New open-access paper by Sam Jones et al. examining the mechanisms governing elevational range limits in the bird communities of Cusuco National Park, Honduras. Results show habitat and behaviour are likely to be more important than physiology in governing altitudinal limits: tinyurl.com/393byxx6

New paper in Coral Reefs by Rebecca Cramp et al. documenting Diadema urchin declines between 2014-2022 in two ecologically-different Caribbean study sites (Utila and Tela), and examining the impacts of these declines on the benthic communities in these sites: tinyurl.com/5bb4khur

Congratulations to Rachel Gunn et al. for their new Aquatic Biology paper which, from examining cleaner gobies on the reefs of Utila, Honduras, shows that cleaner behaviour is complex ,being influenced by a range of behavioural and ecological variables tinyurl.com/ys2bwdw8

Great new paper by Richard Bodmer et al. examining the ecology of River dolphins at fish aggregations in Amazonian Peru. It found that Pink dolphins formed feeding aggregations in both small and large rivers, while Grey dolphin aggregations largely occurred in large rivers; tinyurl.com/ezxjtmaa

New paper out highlighting the threat tropical storms pose to global island biodiversity. It shows the Caribbean especially has many species likely to be at risk of extinction from storms, and identifies 60 'high-risk' species that could be wiped by a single future storm event: shorturl.at/EAqOS

New open-access paper by Asela Buenfil-Rojas et al. describing a method to extract RNA from Morelet's Crocodile scuts (partly based on samples obtained from our Calakmul site), just out in MethodsX - shorturl.at/PXBFO

New paper by Rodney Roundtree et al. examining the acoustical ecology of dolphins and fish in the Pacaya-Samiria Reserve, Peru. They document distinct dolphin sounds seemingly used in different situations, and show a correlation between dolphin & fish acoustical activity: shorturl.at/gxerkhttps:/...

New paper by Hrvoje Čižmek et al. on the ecology of the Critically Endangered Noble Pen Shell off Miljet, Croatia. Results show the population to be dominated by older individuals, making it vulnerable to the mass mortality events posing a particular risk to the species: www.mdpi.com/2073-4441/17...

New paper led by Deepankar Mahabale examining hunting sustainability in a community-led wildlife management plan in the Peruvian Amazon. Results show planned quotas with community buy-in can yield sustainable hunting yields, and such approaches may be a counter to illegal hunting: shorturl.at/OTlSL

New paper out last month pooling standardized reef monitoring data from across the globe (including our research site on Hoga, Indonesia) to examine state shifts in reef ecosystems. Results show concerning shifts from reefs dominated by hard corals to more algae-dominated reefs: shorturl.at/4v7dV

Very pleased to participate in the first Ocean Advocacy Summit in Bristol soon, where Alex O’Brien & Catherine Edsell will discuss the importance of citizen science in marine conservation. The summit is on 1st Feb - you can find more here: ocean-advocate.org/ocean-advoca...
