Genetic Isolation among the Northwestern, Southwestern and Central-Eastern Indian Ocean Populations of the Pronghorn Spiny Lobster Panulirus penicillatus

Abstract

The pronghorn spiny lobster Panulirus penicillatus is a highly valuable species which is widely distributed in Indo-West Pacific and Eastern Pacific regions. Mitochondrial DNA control region sequences (566–571 bp) were determined to investigate the population genetic structure of this species in the Indian Ocean. In total, 236 adult individuals of Panulirus penicillatus were collected from five locations in the Indian Ocean region. Almost all individuals had a unique haplotype. Intrapopulation haplotype (h) and nucleotide (π) diversities were high for each locality, ranging from h = 0.9986–1.0000 and π = 0.031593–0.043441. We observed distinct genetic isolation of population located at the northwestern and southwestern edge of the species range. Gene flow was found within localities in the central and eastern region of the Indian Ocean, probably resulting from an extended planktonic larval stage and prevailing ocean currents.

Testing dispersal limits in the sea: range‐wide phylogeography of the pronghorn spiny lobster Panulirus penicillatus

“…), corroborating data from Abdullah et al . (), and in accordance with the Briggs & Bowen Red Sea province. The isolation of the Red Sea population (0.7 Ma; HPD = 0.42–1.1 Ma) occurred after the divergence between the East Pacific and the IWP P. penicillatus populations (1.5 Ma; HPD = 0.89–2.3 Ma), and was likely due to sea level fluctuation in the mid‐Pleistocene.…”

“…In contrast to expectations based on PLD, recent evidence indicates genetic differentiation between East and West Pacific populations of P. penicillatus (Chow et al ., ), and between Indian Ocean and Red Sea populations (Abdullah et al ., ). There is also morphological variation across the species range.…”

First record of Puerulus mesodontus Chan, Ma & Chu, 2013 (Crustacea, Decapoda, Achelata, Palinuridae) from south of Java, Indonesia

“…Most works on Indonesian lobsters have focused on the economically important species, such as diversity, distribution and genetic population of Panulirus penicillatus Olivier 1791 (Chow et al 2011, Kalih 2012, Abdullah et al 2014), first record occurrence and sexual dimprphism of Linuparus somniosus Berry and George 1972 (Wowor 1999), size distribution, length-weight relationship, condition factor, and sex ratio of Panulirus versicolor Latreille 1804 (Ongkers et al 2014), and the distribution of Panulirus homarus (Linnaeus 1758), P. longipes (Milne-Edwards 1868), P. ornatus (Fabricius 1798), and Parribacus antarticus (Lund 1793) in Lombok island and its surrounding waters (Kalih 2012). In this paper we present the first record of Puerulus mesodontus from Pelabuhanratu Bay, southern Java.…”

Two Newly Recorded Species of the Lobster Family Scyllaridae (Thenus indicus and Scyllarides haanii) From South of Java, Indonesia

“…Albunea symmista , Hippa marmorata , Hippa adactyla , Puerulus mesodontus (Wardiatno et al 2016)]. Studies on lobsters in Indonesia mostly focused on highly economically valuable species, such as P. penicillatus (Chow et al 2011;Kalih 2012;Abdullah et al 2014), Linuparus somniosus (Wowor 1999), P. versicolor (Ongkers et al 2014), P. homarus, P. longipes, P. ornatus (Kalih 2012), and P. mesodontus (Wardiatno et al 2016). A study on the occurrence of the slipper lobster, P. antarticus, in the coastal waters of Lombok Island, Indonesia, was reported by Kalih (2012).…”

“…Much information on palinurid lobsters [i.e. Panulirus penicillatus (Chow et al 2011;Kalih 2012;Abdullah et al 2014), Panulirus versicolor (Ongkers et al 2014), Panulirus homarus, Panulirus longipes, and Panulirus ornatus (Kalih 2012)] has been reported, but little information is available on slipper lobsters [e.g. Parribacus antarticus (Kalih 2012)].…”
