The “ACCOBAMS Survey Initiative” (ASI) is a pilot programme aimed at establishing an integrated and coordinated monitoring system for cetaceans across the Agreement on Conservation of Cetaceans Black Sea, Mediterranean Sea contiguous Atlantic (hereafter “ACCOBAMS”) area. Conducted in coordination with coastal countries, it supports implementation European regional policies, particular EU Marine Strategy Framework Directive Ecosystem Approach process. In summer 2018, synoptic survey was...

Heterogeneous data collection in the marine environment has led to large gaps our knowledge of species distributions. To fill these gaps, models calibrated on existing may be used predict distributions unsampled areas, given that available are sufficiently representative. Our objective was evaluate feasibility mapping cetacean densities across entire Mediterranean Sea using survey and various environmental covariates. We aggregated 302,481 km line transect effort conducted within past 20...

We investigated the presence and diversity of cetaceans in Mediterranean Sea, analysing data collected by 32 different research units, over a period 15 years (2004–2018), shared on common web-GIS platform named Intercet. used encounter rate, species prevalence, Shannon index as parameters for analysis. The results show that cetacean diversity, context basin, is generally quite low when compared with eastern Atlantic, few species, namely striped dolphin, bottlenose fin whale, sperm dominate...

Abstract Aim Deep‐diving cetaceans are oceanic species exposed to multiple anthropogenic pressures including high intensity underwater noise, and knowledge of their distribution is crucial manage conservation. Due intrinsic low densities, wide ranges limited presence at the sea surface, these rarely sighted. Pooling data from visual surveys sharing a common line‐transect methodology can increase sightings but requires accounting for heterogeneity in protocols platforms. Location North...

ABSTRACT The Mediterranean sperm whale sub‐population is considered ‘Endangered’ by both ACCOBAMS and the IUCN. Conservation policies require protected species populations to be monitored, but distribution movements of whales across Sea are still poorly understood. To provide insight into movements, photo‐identification catalogue from Strait Gibraltar was compared with seven other collections: (a) North Atlantic Sperm Whale Catalogue (NAMSC), catalogues (b) Alboran Sea, Spain, (c) Balearic...

Introduction Conservation of cetaceans is challenging due to their large-range, highly-dynamic nature. The EU Habitats Directive (HD) reports 78% species in ‘unknown’ conservation status, and information on low-density/elusive such G.griseus, G.melas, Z.cavirostris the most scattered. Methods FLT-Net programme has regularly collected year-round data along trans-border fixed-transects Mediterranean Sea since 2007. Nearly 7,500 cetacean sightings were recorded over 500,000 km effort with 296...

The Pelagos Sanctuary hosts eight resident cetacean species. Genetically different from Atlantic populations, their conservation is essential to preserve the whole biodiversity of Ligurian Sea.

ABSTRACT Understanding the habitat of highly migratory species is aided by using distribution models to identify species‐habitat relationships and inform conservation management plans. While Generalized Additive Models (GAMs) are commonly used in ecology, particularly modeling marine mammals, there remains a debate between (presence/absence) versus density (# individuals). Our study assesses performance predictive capabilities GAMs compared boosted regression trees (BRTs) for both fin whale...

Abstract The EU regulative framework for the protection of marine biodiversity and habitats requires assessment species' conservation status identification core to design adequate management plans. However, distribution range habitat‐use pelagic large‐range, migratory species, such as cetaceans, is challenging. Species models (SDMs) are increasingly used in planning identify species priority areas. quality SDMs varies widely depending on representativeness data appropriateness modelling...

Environmental policies, including the European Marine Strategy Framework Directive (MSFD), generally rely on measurement of indicators to assess good environmental status (GES) and ensure protection marine ecosystems. However, depending available scientific knowledge monitoring programs in place, quantitative GES assessments are not always feasible.

Abstract The Mediterranean Sea is a high‐density maritime traffic area, particularly in the Pelagos Sanctuary. Ship strikes pose substantial threat to fin whales ( Balaenoptera physalus ) according reports from IUCN, IWC, ACCOBAMS and EU Habitats Directive. Near miss events (NMEs) were collected, as proxy indicator of ship for whales, along main ferry routes crossing Sanctuary adjacent western waters during ‘summertime’ (April October). ‘Fixed Line Transect Med Network’ carries out...
