Dear MARMAMers,
My coauthors and I are pleased to announce our new publication on the use of
Ecological Niche Factor Analysis for common dolphin conservation:
Giralt Paradell O, Diaz Lopez B, Methion S. 2019. Modelling common dolphin
(Delphinus delphis) coastal distribution and habitat use: Insights for
conservation. Ocean and Coastal Management. DOI:
10.1016/j.ocecoaman.2019.104836
Abstract
The world’s ecosystems are altered to different extents by anthropogenic
activities. Marine habitats, especially coastal areas, are subjected to an
increasing pressure derived from human activities on both land and ocean.
Information about species distribution is fundamental to develop effective
conservation and management measures and counteract negative anthropogenic
impacts. The present work explores the use of species distribution models by
using the Environmental Niche Factor Analysis (ENFA) to assess the habitat
suitability of common dolphins (Delphinus delphis) in Northwest Spain, and its
application to the development of effective conservation and management
measures. The relationship between presence-only data and ecogeographical
variables (EGV) was used to assess the potential distribution of the species.
Data was collected during 273 days at sea, covering a total distance of 9 417
km between March 2014 and October 2017 with a total of 91 common dolphin
encounters. This study shows that tide level and sea surface salinity are the
main EGVs driving the distribution of the species in coastal areas especially
in waters above the continental shelf. Additionally, this study reveals the
most suitable habitats for common dolphin and outlines the need to develop
conservation measures and management plans to promote the protection of this
species. Findings of the study contribute to a more accurate and comprehensive
understanding of the common dolphin distribution and emphasize the importance
of species distribution models in the development of effective conservation and
management strategies.
