Ontogeny of foraging behaviour in an opportunistic gull inhabiting urban marine ecosystems
Wildlife Biology, EarlyView.Urbanization affects ecosystems by reducing biodiversity and displacing species from native habitats. While some suffer, others, like urban wildlife, adapt through innovative feeding and behaviours that improve their fitness in human‐altered settings. Despite research on wildlife in urban areas, the development of foraging behaviour in urban species is

Bat Tongues and Foraging: Linking Morphology to Hunting Strategies
Integrative Zoology, EarlyView.We linked the bat tongue's mediodorsal lobe (MDL), a muscular prominence, to foraging strategies. Aerial hawkers exhibit tall MDLs and prominent forward‐pointing papillae. The MDL may function as a barrier or filter, preventing unintentional ingestion of non‐food material, aiding in prey handling, and controlling food access during fast flight ...

Bottlenose Dolphins, Tursiops truncatus, Removing By-catch from Prawn-trawl Codends During Fishing in New South Wales, Australia [PDF]
, 1998 During a fishing trip to record video footage of fish escaping from a by-catch reducing device located in a commercial prawn trawl, two bottlenose dolphins, Tursiops truncatus, were observed to actively manipulate the codend at the seabed, removing and ...

Integrative Zoology, EarlyView.This work aimed to apply the principles of skin mark analysis to a cetacean species to build a sex‐discrimination model exclusively based on photographic material. Relevant differences between sexes emerged in markings, with males presenting more social, aggression‐related, and fishing‐related marks overall, and a stronger tendency of mark accumulation

Geographic Patterns of Head Morphology in Syngnathus typhle Across Marine Regions
Integrative Zoology, EarlyView.Morphometric analysis of Syngnathus typhle head shape shows distinct geographic patterns across Baltic, North, Atlantic, and Mediterranean marine regions, driven by variation in snout length, head depth, and eye position. Findings provide a non‐invasive baseline for conservation monitoring.

Frontiers in Marine Science, 2019 Fishing pressure is often expressed in terms of a vessels physical attributes, like tonnage and engine power, while a common definition of fishing capacity identifies vessel size as a convenient proxy for the size of the gear used.

Current issues relating to artificial reefs in European seas
, 2000 European artificial reef research has now been active for about three decades. For much of that time research has been conducted within national programmes, focussing on national or local issues, and has taken place predominately in the Mediterranean Sea.
