🌊 Can planktonic pteropods with thin shells protect themselves against ocean acidification? 💎 In the latest Hidden Gem from ICES Journal of Marine Science: pteropods, important bioindicators of ocean health, defend themselves against ocean acidification through a unique protective shell coating, the periostracum. This study demonstrates that even a thin periostracum can protect against shell dissolution, challenging previous assumptions about pteropod vulnerability. The results of this study not only enhance our understanding of pteropod resilience but also underscore the complex mechanisms marine species have evolved to withstand environmental stressors.

Structural diversity of Leiopathes glaberrima populations in the strait of Sicily: from pristine to declining forests - Frontiers in Marine Science: Introduction: The black coral Leiopathes glaberrima is a key component of deep-sea animal forests of the Western Mediterranean and North-Atlantic hard bottoms. Due to its ecological role, biological characteristics and sensitivity to fishing activities, it has been included in the Annex II of the Barcelona Convention, listed as an endangered species in IUCN Red Lists, and recognized as an indicator of Vulnerable Marine Ecosystems by the FAO. https://lnkd.in/epQiDQSg

Dive into the Depths of Data! Our latest #BioDT paper unveils a treasure trove of fish sampling insights from the Minho Estuary. From 2010 to 2019, the team including Allan Souza Martina Ilarri, Esther Dias, Mário J Araújo, Antonio Roleira, Ana Catarina Braga, @Ana Rita Carvalho, Micaela Mota, Maria Helena Correia, Ana Lages, Ana Moura, Carlos Antunes have meticulously gathered data in Lenta Marina, an upstream area in the NW Iberian Peninsula, as part of the LTSER platform. 🔔 Using fyke nets, we captured a wealth of information on fish abundance, meticulously documenting each taxa's presence or absence. Our dataset offers a rare glimpse into the ebb and flow of fish populations over time, with sampling occurring every 6 days on average. 🔔 What's groundbreaking? Our findings reveal a stark reality: invasive fish species outnumber native ones in the Minho Estuary. This discovery underscores the urgency of understanding and managing ecological shifts in our waterways. 🔔 Whether you're a researcher, conservationist, or just fascinated by aquatic ecosystems, this data paper is worth a read: https://lnkd.in/eX7QNpVq #FishSampling #EcologicalResearch #DataInsights

Wolves in human-modified ecosystems will engage in an array of novel interactions and potential novel trophic cascades that do not occur in more natural ecosystems with lower human impact

Stereo-video landers can rapidly assess marine fish diversity and community assemblages - Frontiers in Marine Science: Climate change and anthropogenic stressors affect the distribution, abundance, and diversity of fish communities across the world. To understand rapidly changing biotic communities, resource managers need a method to quickly and efficiently document temporal and spatial changes in community assemblages across various spatial scales. In this study, we describe the use of new video lander tools to survey fish communities in rocky marine habitats on the continental shelf and slope in California, USA. We evaluate how fish diversity metrics determined by video surveys vary among geographically distinct areas. Our results demonstrate that species diversity, evenness, and richness vary spatially across the coast. Furthermore, community assemblages differ at both broad and fine spatial scales because of differences among habitats. Length frequencies and densities of species in this study were similar to those reported in previous studies. As community assemblages and biodiversity metrics shift in response to changing stressors, it is increasingly important to develop tools and methodologies to detect and rapidly monitor these changes.

🐟 "Climate change is making it almost impossible to decide how much, where and what to sustainably fish as the fate of future fisheries is becoming increasingly uncertain. ... As the Arctic Ocean loses sea ice due to climate change, fisheries access is increasing, and large-scale exploitation is on the horizon. These changes threaten the fragile Arctic Ocean ecosystem that harbours polar bears, beluga whales, narwhals and a range of fish species, such as Arctic char and Greenland halibut. ... [Now] is the time to establish a proactive, precautionary and climate-informed management framework that considers the unique and fragile Arctic ecosystem — before any explorative fishery and ideally before large-scale, unregulated fishing activities." 🐟 Check out this article in The Conversation Canada from Andrea Bryndum-Buchholz, Postdoctoral Researcher in Marine Ecology and Climate-Impact Sciences, at Memorial University, Newfoundland and Labrador University of Newfoundland, to learn more about how we can support a sustainable and just future for the Arctic. 🐟 Read here: https://lnkd.in/e7eyhJQG
