New water mites of the family Hygrobatidae (Acari,?Hydrachnidia) from Turkey

In this study, the findings of three water mite species of the family Hygrobatidae collected from different streams in Turkey were evaluated. Hygrobates (s. str.) anatolicus Esen & Pešić, sp. n. is described as new for science. Hygrobates (Rivobates) diversiporus Sokolow, 1927 and Atractides (s. str.) nikooae Pešić, 2004, which were illustrated and thoroughly discussed, are new records for the Turkish fauna.

Genome-wide association study for feed efficiency in collective cage-raised rabbits under full and restricted feeding

Feed efficiency (FE) is one of the most economically and environmentally relevant traits in the animal production sector. The objective of this study was to gain knowledge about the genetic control of FE in rabbits. To this end, GWASs were conducted for individual growth under two feeding regimes (full feeding and restricted) and FE traits collected from cage groups, using 114 604 autosome SNPs segregating in 438 rabbits. Two different models were implemented: (1) an animal model with a linear regression on each SNP allele for growth trait; and (2) a two-trait animal model, jointly fitting the performance trait and each SNP allele content, for FE traits. This last modeling strategy is a new tool applied to GWAS and allows information to be considered from non-genotyped individuals whose contribution is relevant in the group average traits. A total of 189 SNPs in 17 chromosomal regions were declared to be significantly associated with any of the five analyzed traits at a chromosome-wide level. In 12 of these regions, 20 candidate genes were proposed to explain the variation of the analyzed traits, including genes such as FTO, NDUFAF6 and CEBPA previously associated with growth and FE traits in monogastric species. Candidate genes associated with behavioral patterns were also identified. Overall, our results can be considered as the foundation for future functional research to unravel the actual causal mutations regulating growth and FE in rabbits.     

New species and records of Stigmaeidae (Acari: Prostigmata) from New Zealand - ID. Genus Stigmaeus Koch

Abstract

Stigmaeus arboricola, S. montanus, S. luxtoni, and S. novazealandicus are described as new species, and the larva of S. loadmani is described. Several new records are noted, and a key is given to the New Zealand species of Stigmaeus.     

Genus Bembidion Latreille (Coleoptera: Carabidae) in New Zealand: A revision

The cosmopolitan genus Bembidion is represented in New Zealand by 20 species, of which 19 are endemic; B. brullei appears to be a recent introduction. On phenetic characters the species fall into 7 subgenera, as follows: Zeplataphus n.subg.—maorinum Bates, dehiscens Broun, charile Bates, granuliferum n.sp., townsendi n.sp., tairuense Bates; Zeactedium Netolitzky—orbiferum Bates, musae Broun; Zeperyphodes n.subg.—callipeplum Bates; Zeperyphus n.subg.—actuarium Broun; Zemetal‐lina n.subg.—chalceipes Bates, solitarium n.sp., anchonoderum Bates, tekapoense Broun, wanakense n.sp., urewerense n.sp., hokitikense Bates, parviceps Bates; Ananotaphus Netolitzky—rotundicolle Bates; Notaphus Stephens—brullei Gemminger & Harold. The North Island population of maorinum is distinct from the typical South Island form in having reduced microscrulpture on the elytra, and is here separated as levatum n.ssp. An apparent geographic isolate of anchonoderum, represented by 2 females from Stewart Island, is provisionally recognised as stewartense n.ssp. The polymorphic complex within subg. Ananotaphus is here regarded as a single species, of which the North Island population is sufficiently distinct to warrant subspecific status as eustictum Bates; however, intergrades occur in the north‐west of the South Island. The following names fall into synonymy: latiusculum Broun (= maorinum); diaphanum Broun (= musae); nesophilum Broun (= callipeplum)’, tinctellum Broun (= chalceipes);antipodum Broun (= anchonoderum)’, tantillum Broun and probably attenuatum Broun (=hokitikense)’, clevedonense Broun and waikatoense Broun (= rotundicolle, ssp. eustictum)’, gameani Jeannel (= brullei). The relationships and aspects of the biology and ecology of the New Zealand Bembidion fauna are discussed.     

Records of fishes from the West Norfolk Ridge,north-west of New Zealand

Abstract

A total of 89 species of elasmobranch and teleost fish was recorded from the West Norfolk Ridge in 1986. Between 50 and 60 of these have not previously been reported from the area. Fish species were caught in bottom trawls at depths between 100 m and 1100 m, principally on the Wanganella Bank. Depth distribution is discussed. Species composition is very similar to that of northern New Zealand.     

Effects of Age,Sex, Index Admission,and Predominant Polarity on the Seasonality of Acute Admissions For Bipolar Disorder: A Population-Based Study

Bipolar disorder seasonality has been documented previously, though information on the effect of demographic and clinical variables on seasonal patterns is scant. This study examined effects of age, sex, index admission, and predominant polarity on bipolar disorder seasonality in a nationwide population. An inpatient cohort admitted to hospital exclusively for mental illness was derived from the Taiwan National Health Insurance Research Database for 2002–2007. The authors identified 9619 inpatients with bipolar disorder, who had generated 15 078 acute admission records. An empirical mode decomposition method was used to identify seasonal oscillations in bipolar admission data, and regression and cross-correlation analyses were used to quantify the degree and timing of bipolar admission seasonality. Results for seasonality timing found that manic or mixed episodes peak in spring or summer, and depressive episodes peak in winter. Analysis for degree of seasonality revealed that (1) the polarity of patients' index admission predicted the seasonality of relapse admissions; (2) seasonality was significant in female admissions for depressive episodes and in male admissions for manic episodes; (3) young adults displayed a higher degree of seasonality for acute admissions than middle-aged adults; and (4) patients with predominantly depressive admissions displayed a higher degree of seasonality than patients with predominantly manic admissions. Demographic and clinical variables were found to affect the seasonality of acute admissions for bipolar disorders. These findings highlight the need for research on identification and management of seasonal features in bipolar patients. (Author correspondence: ccyang@physionet.org)     

The first checklist of black fungus gnats (Diptera: Sciaridae) of Morocco

The first checklist of black fungus gnats is established; new faunistic records of Sciaridae are presented, providing a list of 10 genera and 55 species. Forty-eight species are newly listed for Morocco, increasing the total of Sciaridae known from Morocco to 69 species, belonging to 12 genera, of which six (Austrosciara Schmitz & Mjöberg, 1924, Bradysiopsis Tuomikoski, 1960, Epidapus Haliday, 1851, Lycoriella Frey, 1942, Pseudolycoriella Menzel & Mohrig, 1998 and Sciara Meigen, 1803) are newly reported for Moroccan fauna.
