Alder

The Alder (Alnus glutinosa) is a species in the genus Alnus. It is currently classified as Least Concern on the IUCN Red List. Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Common Prawn

The Common Prawn, <em>Palaemon serratus</em>, is a decapod crustacean in the family Palaemonidae, widely distributed along the Atlantic coasts of Europe, including the waters of Belgium, Denmark, Norway, Portugal, and Sweden. It inhabits shallow coastal waters, estuaries, rock pools, and seagrass meadows, typically sheltering among algae, rocks, and submerged vegetation during the day and foraging more actively at night. <em>Palaemon serratus</em> is an omnivorous opportunist, typically consuming algae, small invertebrates, detritus, and organic particles. The species is transparent to pale greenish-brown with distinctive reddish-brown banding on the antennae and legs. It is an important prey item for coastal fish species and seabirds, and supports small-scale artisanal fisheries across its European range. The species plays a role in benthic nutrient cycling through its feeding activity. It reproduces seasonally, with females carrying eggs attached to the pleopods until hatching. The Common Prawn is currently Not Evaluated on the IUCN Red List, meaning a formal assessment of its conservation status has not yet been completed. Biological traits such as average lifespan, body size, and specific dietary preferences remain poorly documented for this species.
