Phylogenetic Relationships of Selected Genera of Lutjanidae Inferred from Mitochondrial Regions, with a Note on the Taxonomic Status of Pinjalo Pinjalo
Ciencias Marinas (2013), 39(4): 349–361 http://dx.doi.org/10.7773/cm.v39i4.2287 C M Phylogenetic relationships of selected genera of Lutjanidae inferred from mitochondrial regions, with a note on the taxonomic status of Pinjalo pinjalo Relaciones filogenéticas de algunos géneros de la familia Lutjanidae inferidas a partir de regiones mitocondriales, con una nota sobre la taxonomía de Pinjalo pinjalo Cecilia Chu1, Mohammed Rizman-Idid1,2*, Chong Ving Ching1,2 1 Institute of Biological Sciences, Faculty of Science, University of Malaya, 50603 Lembah Pantai, Kuala Lumpur, Malaysia. 2 Institute of Ocean and Earth Sciences, University of Malaya, 50603 Lembah Pantai, Kuala Lumpur, Malaysia. * Corresponding author. Email: [email protected] ABSTRACT. Phylogenetic relationships of 43 species in 11 genera, representing four subfamilies of the family Lutjanidae and two genera of the family Caesionidae, were inferred using mitochondrial DNA (mtDNA) cytochrome c oxidase subunit I (COI). Further assessment using the mtDNA control region (CR) was carried out to infer the relationship between the Indian and western Pacific types of Lutjanus russellii collected from the coast of Peninsular Malaysia. A total of 11 and 12 species were sequenced for COI and CR genes, respectively. Clade formation reflects, to some extent, the species groupings based on morphological characteristics and their biogeography. The close phylogenetic relationship between Pinjalo pinjalo and the Lutjanus red snappers (Lutjanus malabaricus and Lutjanus sebae) warrants a taxonomic revision of the former as the two genera are currently separated based on non-exclusive morphological characters. A sequence divergence of 4.2% between the Indian and western Pacific types of L. -

And Long-Term Movement Patterns of Six Temperate Reef Fishes (Families Labridae and Monacanthidae)
Mar: Freshwater Res., 1995,46, 853-60 Short- and Long-term Movement Patterns of Six Temperate Reef Fishes (Families Labridae and Monacanthidae) Neville S. Barrett Zoology Department, University of Tasmania, GPO Box 252C Hobart, Tas. 7001, Australia. Abstract. Movement patterns were studied on a 1-ha isolated reef surrounding Arch Rock in southern Tasmania. Short-term movements were identified from diver observations, and interpretation of long-term movements involved multiple recaptures of tagged individuals. Visual observations indicated that the sex-changing labrids Notolabrus tetricus, Pictilabrus laticlavius and Pseudolabrus psittaculus were all site-attached, with females having overlapping home ranges and males being territorial. In the non-sex-changing labrid Notolabrus fucicola and in the monacanthids Penicipelta vittiger and Meuschenia australis, there was no evidence of territorial behaviour and I-h movements were in excess of the scale of the study. The long-term results indicated that all species were permanent reef residents, with most individuals of all species except M. australis always being recaptured within a home range of 100 m X 25 m or less. Only 15% of individuals of M. australis were always recaptured within this range category. The natural habitat boundary of open sand between the Arch Rock reef and adjacent reefs appeared to be an effective deterrent to emigration. The use of natural boundaries should be an important consideration in the design of marine reserves where the aim is to minimize the loss of protected species to adjacent fished areas.

A faster rate of reproductive gain with body size can occur if larger males are more effective in controlling females and excluding competitors from fertilizations. The most simple consequence of this theoretical scenario, based on sexual allocation theory, is that natural breeding sex ratios are expected to be female biased in female-first sex changers, because average male fecundity will exceed that of females. A second prediction is that the intensity of sperm competition is expected to be lower in female-first sex-changing species because larger males should be able to more completely monopolize females and therefore reduce male–male competition during spawning. -

ALLEN Department of Aquatic Zoology, Western Australian Museum, Locked Bag 49, Welshpool DC, Perth, Western Australia 6986 E-mail: [email protected] Abstract A new species of snapper of the genus Lutjanus is described from the Indo-western Pacific region, and the related species with which it frequently has been confused, Lutjanus madras (Valenciennes 1831), is redescribed. Lutjanus xanthopinnis n. sp. is described from 11 specimens, 56–192 mm SL, from Kagoshima in southern Japan, Taiwan, Indonesia, and Sri Lanka. It differs from L. madras in meristics, color, and squamation of the preopercular flange. The new species is distinguished by several embedded scales on the preopercular flange, 4 or 5 scale rows on the cheek, and mostly uniform thin yellow to brownish stripes on the body on adults, missing the well-contrasted and much broader mid-lateral stripe characteristic of L. madras. In contrast, L. madras lacks scales on the preopercular flange, has 7 or 8 scale rows on the cheek, and has a broad (up to pupil diameter), well- contrasted yellow to brownish stripe along the lateral midline. -

Attachment H to Proposed Approval Decision Brief Lord Howe Island Rodent Eradication Project, NSW (EPBC 2016/7703) Proposed Approval Decision ERT Review A search of the Department's Environmental Reporting Tool (ERT) on 13 July 2017 identified an additional six listed threatened species and ten migratory species that were not identified in an ERT search on 20 June 2016 (the same co-ordinates were used in the two ERT searches), within a parallelogram that encompasses all the islands of the Lord Howe Island Group (except for Balls Pyramid) and within a buffer of 2 km from the parallelogram. These species were not considered at the time of the controlled action decision on 17 September 2014. Listed threatened species The following threatened species (although previously listed under the EPBC Act) were not identified by the ERT at the time the controlled action decision was made, and therefore were not considered during the assessment process: Red Knot (Calidris canutus) - endangered Curlew Sandpiper (Calidris ferruginea) – Critically endangered Herald Petrel (Pterodrama heraldica) - Critically endangered Pacific Albatross (Thalassarche bulleri platei) – Vulnerable Sei Whale (Balaenoptera borealis) – Vulnerable Fin Whale (Balaenoptera physalus) - Vulnerable These species were identified in the SPRAT search of 13 July 2017 because their distributions were updated in SPRAT subsequent to the controlled action decision for this project. The Department recently assessed the potential impacts of the proposed action on the above species and concluded that it was highly unlikely that they would be significantly impacted by the proposal. The following is a summary of this assessment Red Knot (Calidris canutus) – endangered This species is a rare, regular visitor to LHI (13 records between 1990 and 2004). -
Marine Reserve Networks Conserve Biodiversity by Stabilizing Communities and Maintaining Food Web Structure
Marine reserve networks conserve biodiversity by stabilizing communities and maintaining food web structure STEPHEN R. WING AND LUCY JACK Department of Marine Science, University of Otago, 310 Castle Street, Dunedin, New Zealand 9054 Citation: Wing, S. R., and L. Jack. 2013. Marine reserve networks conserve biodiversity by stabilizing communities and maintaining food web structure. Ecosphere 4(10):XXX. http://dx.doi.org/10.1890/ES13-00257.1 Abstract. Theory predicts that networks of fully protected marine reserves conserve biodiversity by stabilising communities and maintaining food web structure in the face of inadequately constrained fishery exploitation. To test these ideas we examine trends in species incidence, community and trophic structure of temperate reef fishes over an eight year period within the Fiordland no-take marine reserve network, at management zones subject to commercial fishing and at those closed to commercial exploitation but open to recreational fishers. We use information from extensive stratified subtidal surveys of the reef fish community and abundance of macroalgae, as well as oceanographic data collected in 2002, 2006 and 2010. Our analyses indicate a regional decline in species richness of exploited reef fish in areas open to fishing between 2002 and 2010. Following implementation of spatial management (2006–2010), richness of ‘exploited’ species increased within marine reserves, but remained unchanged in areas open to fishing. Further, analysis of differences in community structure in this time period (2006–2010) indicate that both ‘exploited’ and ‘non-target’ groups were more stable within marine reserves than were those within fished areas. Consequentially average trophic level of the community remained stable within marine reserves but declined sharply in areas open to fishing, indicating both declines in large omnivorous species and increases in forage fish within exploited regions. -
