Article Synopsis
- Global warming is affecting lakes' thermal dynamics and mixing patterns, particularly highlighted by a study on Lake Sevan in Armenia.
- The researchers developed a dual ensemble workflow that combines climate models with hydrodynamic lake models to analyze the impact of climate change across various scenarios.
- Their findings predict significant changes by the end of the century, including increased surface temperatures, longer periods of stratification, and the loss of ice cover, indicating Lake Sevan's vulnerability to climate change while offering a more accurate uncertainty assessment for future studies.
The evolutionary theory of life histories predicts that there is a trade-off between survival and reproduction: since adult survival in long-lived organisms is high, then breeding investment is more variable and more dependent on conditions (e.g. food availability and individual experience).

Fear of predation can affect important ecosystem processes by altering the prey traits expression that, in turn, regulates the quantity and quality of nutritional inputs to soil. Here, we aimed to assist in bridging a knowledge gap in this cascading chain of events by exploring how risk of spider predation may affect grasshopper prey performances, and the activity of various microbial extracellular enzymes in the soil. Using a mesocosms field-experiment, we found that grasshoppers threatened by spider predation ate less, grew slower, and had a higher body carbon to nitrogen ratio.

- Abiotic factors, such as temperature and nutrients, significantly shape plant-herbivore interactions, impacting the stability of ecosystems like marine forests.
- Overgrazing, particularly by sea urchins, has led to the spread of barren areas on rocky reefs, which function differently than vegetated habitats and require new understandings to reverse these trends.
- Research found that limpets thrive in barren areas created by urchin overgrazing, with their grazing effects varying by nutrient levels, thus indicating that low-nutrient conditions heighten the vulnerability of these ecosystems in the Mediterranean.

Background: To date, the genus (Annelida: Hesionidae: Amphidurine) is considered as monotypic. Its single species, (Marenzeller, 1875), is well characterised by lacking proboscideal papillae and emerging acicular chaetae, as well as by having three antennae, eight pairs of tentacular cirri and inflated dorsal cirri with characteristic alternating length and colour (transparent, with median orange band and white tips) in live animals.
New Information: Three specimens, one male and two females, were found below boulders at 5-7 m depth in Punta Santa Anna, Blanes and Cala Maset, Sant Feliu de Guixols (Catalan Sea, NW Mediterranean, Iberian Peninsula).
