A new species of <Emphasis Type="Italic">Triloculotrema</Emphasis> Kearn, 1993 (Monogenea: Monocotylidae) from a deep-sea shark,the blacktailed spurdog <Emphasis Type="Italic">Squalus melanurus</Emphasis> (Squaliformes: Squalidae), off New Caledonia

Triloculotrema chisholmae n. sp. is described from three specimens collected from the nasal tissues of a deep-sea shark, the blacktailed spurdog Squalus melanurus Fourmanoir & Rivaton, caught off New Caledonia, South Pacific. The new species is distinguished from the only other and type-species of the genus, T. japanicae Kearn, 1993, by the morphology of the sclerotised male copulatory organ (shorter and straight versus curved) and shorter hamuli.

Résumé   Triloculotrema chisholmae n. sp. est décrit à partir de trois spécimens récoltés dans les tissus nasaux d’un requin de profondeur, l’aiguillat à queue noire Squalus melanurus Fourmanoir & Rivaton, pêché au large de la Nouvelle-Calédonie, Pacifique Sud. La nouvelle espèce est distinguée de l’espèce-type et seule autre espèce du genre, T. japanicae Kearn, 1993, par la morphologie de l’appareil copulateur male sclérifié (plus court, et droit au lieu de courbe), et par des hamuli plus courts.

     

<Emphasis Type="Italic">Alcicornis haroldi</Emphasis> n. sp. (Digenea: Bucephalidae) from the yellowspotted trevally <Emphasis Type="Italic">Carangoides fulvoguttatus</Emphasis> (Forsskål) (Carangidae) from off New Caledonia

Alcicornis haroldi n. sp. is described from Carangoides fulvoguttatus from off New Caledonia, South Pacific. It differs from all other Alcicornis spp. in its large protuberant pharynx, and from the most similar species, A. baylisi Nagaty, 1937, in its broader rhynchus, indistinct withdrawn tentacles and vitelline distribution.     

HAT: Hypergeometric Analysis of Tiling-arrays with application to promoter-GeneChip data

Background  

Tiling-arrays are applicable to multiple types of biological research questions. Due to its advantages (high sensitivity, resolution, unbiased), the technology is often employed in genome-wide investigations. A major challenge in the analysis of tiling-array data is to define regions-of-interest, i.e., contiguous probes with increased signal intensity (as a result of hybridization of labeled DNA) in a region. Currently, no standard criteria are available to define these regions-of-interest as there is no single probe intensity cut-off level, different regions-of-interest can contain various numbers of probes, and can vary in genomic width. Furthermore, the chromosomal distance between neighboring probes can vary across the genome among different arrays.     

Rapid commencement of ecosystem recovery following aerial baiting on sub‐Antarctic Macquarie Island

Introduced rabbits have severely impacted the terrestrial ecosystem of sub‐Antarctic Macquarie Island. Here we describe first observations of rapid recovery of an important plant species following the commencement of a vertebrate pest eradication plan. The tussock grass Poa foliosa, a major component of the Macquarie Island landscape, has been severely impacted by rabbit grazing with large‐scale reductions in cover across the island observed at times over the last 50 years. Preliminary aerial baiting for rabbits and rodents commenced in winter 2010, and within 6 months, we observed substantial regrowth of tussock grass. The rapid re‐emergence of this grass over such a short time period following localised removal of rabbits has positive implications for the island’s recovery and provides insight for restoration monitoring.
