Racism and Health Among Aotearoa New Zealand Young People Aged 15-24 years: Analysis of Multiple National Surveys.

Purpose: This Aotearoa New Zealand-based study addresses a gap in literature focusing on individual experiences of racism among adolescents and young adults and its links to health.

Methods: This cross-sectional study uses data from multiple instances of the New Zealand Health Survey (2002/03, 2006/07, 2011/12, 2016/17) and General Social Survey (2008-2016) restricted to participants aged 15-24 years. Prevalence of reported experiences of racism are estimated.

Parasite diversity and ecology in a model species, the guppy () in Trinidad.

The guppy () is a model species in ecology and evolution. Many studies have examined effects of predators on guppy behaviour, reproduction, survival strategies, feeding and other life-history traits, but few have studied variation in their parasite diversity. We surveyed parasites of 18 Trinidadian populations of guppy, to provide insight on the geographical mosaic of parasite variability, which may act as a source of natural selection acting on guppies.

Mitochondrial genomes of two phlebotomine sand flies, Phlebotomus chinensis and Phlebotomus papatasi (Diptera: Nematocera), the first representatives from the family Psychodidae.

Background: Leishmaniasis is a worldwide but neglected disease of humans and animal transmitted by sand flies, vectors that also transmit other important diseases. Mitochondrial genomes contain abundant information for population genetic and phylogenetic studies, important in disease management. However, the available mitochondrial sequences of these crucial vectors are limited, emphasizing the need for developing more mitochondrial genetic markers.

Complete mitochondrial genomes for Icelus spatula, Aspidophoroides olrikii and Leptoclinus maculatus: pan-Arctic marine fishes from Canadian waters.

Three Arctic marine fishes Icelus spatula, Aspidophoroides olrikii and Leptoclinus maculatus have been identified as target species for investigating the effects of ocean warming on population patterns in high-latitude marine habitats around Canada. In preparation for this research, we have resolved whole mitochondrial genome sequences of 16 384, 17 200 and 16 384 bp for each species, respectively. GC content for each species was 47.

The mitochondrial genome of Paragyrodactylus variegatus (Platyhelminthes: Monogenea): differences in major non-coding region and gene order compared to Gyrodactylus.

Background: Paragyrodactylus Gvosdev and Martechov, 1953, a viviparous genus of ectoparasite within the Gyrodactylidae, contains three nominal species all of which infect Asian river loaches. The group is suspected to be a basal lineage within Gyrodactylus Nordmann, 1832 sensu lato although this remains unclear. Further molecular study, beyond characterization of the standard Internal Transcribed Spacer region, is needed to clarify the evolutionary relationships within the family and the placement of this genus.

Gyrodactylus leptorhynchi n. sp. (Monogenea) is described from bay pipefish ( Syngnathus leptorhynchus ) (Syngnathidae) in coastal waters of southern California and British Columbia, and from an outbreak of gyrodactylosis at the Cabrillo Marine Aquarium in California.

Occurrence of Glugea pimephales in planktonic larvae of fathead minnow in Algonquin Park, Ontario.

The microsporidian Glugea pimephales was found parasitizing larval fathead minnow Pimephales promelas in Scott Lake, Algonquin Park, Ontario. These fish were estimated to be 2-3 weeks posthatch and, given the development time of the parasite, must have acquired infection soon after commencement of exogenous feeding. Histological sections revealed that the parasite typically developed in loose connective tissue between the peritoneum and the dermis of the abdominal cavity, with protruding xenomas of up to 2.

Novelty-induced arousal enhances memory for cued classical fear conditioning: interactions between peripheral adrenergic and brainstem glutamatergic systems.

Exposure to novel contexts produce heightened states of arousal and biochemical changes in the brain to consolidate memory. However, processes permitting simple exposure to unfamiliar contexts to elevate sympathetic output and to improve memory are poorly understood. This shortcoming was addressed by examining how novelty-induced changes in peripheral and/or central arousal modulates memory for Pavlovian fear conditioning.

Persistence of Dactylogyrus eucalius (Monogenea: Dactylogyridae) on the short-lived host Culaea inconstans (Pisces: Gasterosteiformes).

The monogene Dactylogyrus eucalius Mizelle and Regensberger, 1945 and its ability to maintain a population from year to year on the annual fish Culaea inconstans Kirkland was examined in a small lake in central Ontario. Fish were sampled toward the end of their annual breeding season, at a time when the host population consisted of 2 cohorts, i.e.
