PYCNOIB: biodiversity and biogeography of Iberian pycnogonids.

Soler-Membrives A, Munilla T - PLoS ONE (2015)

Bottom Line: A total of 17,762 pycnogonid records from 343 localities were analyzed and were found to contain 65 species, 21 genera and 12 families.In contrast, the family Nymphonidae has 7 species but is significantly less abundant (<1% of the total records) than Acheliidae.Further deep-water sampling is needed mainly on the Iberian Mediterranean side.

ABSTRACT
Biodiversity and biogeographic studies comparing the distribution patterns of benthic marine organisms across the Iberian Atlantic and Mediterranean waters are scarce. The Pycnogonida (sea spiders) are a clear example of both endemicity and diversity, and are considered a key taxon to study and monitor biogeographic and biodiversity patterns. This is the first review that compiles data about abundance and diversity of Iberian pycnogonids and examines their biogeographic patterns and bathymetric constraints using GIS tools. A total of 17,762 pycnogonid records from 343 localities were analyzed and were found to contain 65 species, 21 genera and 12 families. Achelia echinata and Ammothella longipes (family Acheliidae) were the most abundant comprising ~80% of the total records. The Acheliidae is also the most speciose in Iberian waters with 15 species. In contrast, the family Nymphonidae has 7 species but is significantly less abundant (<1% of the total records) than Acheliidae. Species accumulation curves indicate that further sampling would increase the number of Iberian species records. Current sampling effort suggests that the pycnogonid fauna of the Mediterranean region may be richer than that of the Atlantic. The Strait of Gibraltar and the Alboran Sea are recognized as species-rich areas that act as buffer zones between the Atlantic and Mediterranean boundaries. The deep waters surrounding the Iberian Peninsula are poorly surveyed, with only 15% of the sampling sites located below 1000 m. Further deep-water sampling is needed mainly on the Iberian Mediterranean side.

Major distribution patterns of pycnogonid species.The number of species per patterns are: A = 12, B = 7 (2 including the Strait of Gibraltar), C = 21 (3 including the Strait of Gibraltar) and D = 13 (5 exclusive to the Strait of Gibraltar, 4 to the Catalan coast, 2 to Portugal, and 1 to each Bay of Biscay and Alboran Sea).

Mentions: Patterns and codes of Iberian distribution are related to Figs. 4 and 5. Bathymetric ranges of Iberian pycnogonid species are also shown, as well as their worldwide bathymetric and geographic distributions (C, cosmopolitan; AM, Atlantic-Mediterranean; TA, trans-Atlantic; EA, eastern Atlantic Ocean; WA, western Atlantic Ocean; M, Mediterranean Sea including eastern and western basins; WM, western Mediterranean basin; E, endemic; D, disrupted distribution). In bold, new distribution ranges not published before, and between brackets previous bathymetric distributions before these new data.
