| four new avian mitochondrial genomes help get to basic evolutionary questions in the late cretaceous. | good phylogenetic trees are required to test hypotheses about evolutionary processes. we report four new avian mitochondrial genomes, which together with an improved method of phylogenetic analysis for vertebrate mt genomes give results for three questions in avian evolution. the new mt genomes are: magpie goose (anseranas semipalmata), an owl (morepork, ninox novaeseelandiae); a basal passerine (rifleman, or new zealand wren, acanthisitta chloris); and a parrot (kakapo or owl-parrot, strigops h ... | 2004 | 14739240 |
| first detection of chlamydia psittaci from a wild native passerine bird in new zealand. | to undertake disease surveillance for chlamydia psittaci in native birds as part of a pilot study to examine pathogen diversity on hauturu-o-toi/little barrier island. to retrospectively review the massey university post-mortem database to determine previous cases of avian chlamydiosis in new zealand. | 2013 | 23227890 |
| genetic analysis reveals diverse kin-directed routes to helping in the rifleman acanthisitta chloris. | the social organization of cooperatively breeding species is extremely variable, with diverse social group composition and patterns of relatedness. species that exhibit alternative routes to helping within the same population are potentially useful systems to investigate the causes and fitness consequences of diverse evolutionary pathways to cooperative behaviour. in this study, we use microsatellite markers and field observations to describe helping behaviour and patterns of relatedness in the ... | 2013 | 24033543 |
| ancient mitochondrial genomes clarify the evolutionary history of new zealand's enigmatic acanthisittid wrens. | the new zealand acanthisittid wrens are the sister-taxon to all other "perching birds" (passeriformes) and - including recently extinct species - represent the most diverse endemic passerine family in new zealand. consequently, they are important for understanding both the early evolution of passeriformes and the new zealand biota. however, five of the seven species have become extinct since the arrival of humans in new zealand, complicating evolutionary analyses. the results of morphological an ... | 2016 | 27261250 |
| adult helpers increase the recruitment of closely related offspring in the cooperatively breeding rifleman. | indirect fitness benefits gained through kin-selected helping are widely invoked to explain the evolution of cooperative breeding behavior in birds. however, the impact of helpers on productivity of helped broods can be difficult to determine if the effects are confounded by territory quality or if the benefit of helpers is apparent only in the long term. in riflemen acanthisitta chloris, helping and group membership are effectively decoupled as adult helpers are individuals that have dispersed ... | 2017 | 28028377 |
| a new feather mite of the genus neodectes park and atyeo 1971 (acari: proctophyllodidae) from new zealand wrens (passeriformes: acanthisittidae). | a new feather mite species, neodectes pilgrimi sp. n. (proctophyllodidae: pterodectinae), is described from three species of new zealand wrens (passeriformes: acanthisittidae): xenicus gilviventris pelzeln, 1867 (type host), x. longipes (gmelin, 1789) (extinct species), and acanthisitta chloris (sparrman, 1787). based on known host associations of the genus neodectes, it is hypothesized that neodectes pilgrimi sp. n. has a secondary origin on new zealand wrens and was probably transferred onto t ... | 2017 | 28030355 |

| clinically intensive medical training for combat. | medical training aimed at the rifleman, aidman, and unit operational level for a ranger battalion is described. instruction in patient survey, cardiopulmonary resuscitation, first aid, intravenous resuscitation, and evacuation is given to all rangers. approximately one ranger per rifle squad is trained as a certified emergency medical technician. aidmen attend advanced formal schooling and the battalion runs its own medical sustainment training and expert field medical badge programs. casualty p ... | 1989 | 2511507 |
| does the new zealand rockwren (xenicus gilviventris) hibernate? | in this study, we examined the thermal physiology of the endangered new zealand rockwren (xenicus gilviventris), a member of the acanthisittidae, a family unique to new zealand. this family, derived from gondwana, is thought to be the sister taxon to all other passerines. rockwrens permanently reside above the climatic timberline at altitudes from 1000 to 2900 m in the mountains of south island. they feed on invertebrates and in winter face ambient temperatures far below freezing and deep deposi ... | 2020 | 32291323 |
| the energetics of torpor in a temperate passerine endemic to new zealand, the rifleman (acanthisitta chloris). | compared to other birds, passerines, reflecting their small mass, have a narrow set of behavioral characteristics. one difference is that few enter torpor, especially in temperate environments. the few that do include swallows, none of which live throughout the year in cold-temperate environments, because their food, flying insects, is not available in winter and no passerine is known to hibernate. they seasonally migrate to warm-temperate and tropical environments. we present data on the energe ... | 2018 | 30039298 |
| testing the predictions of sex allocation hypotheses in dimorphic, cooperatively breeding riflemen. | evolutionary theory predicts that parents should invest equally in the two sexes. if one sex is more costly, a production bias is predicted in favour of the other. two well-studied causes of differential costs are size dimorphism, in which the larger sex should be more costly, and sex-biased helping in cooperative breeders, in which the more helpful sex should be less costly because future helping "repays" some of its parents' investment. we studied a bird species in which both processes should ... | 2018 | 29686850 |
| the influence of personal protection equipment, occupant body size, and restraint system on the frontal impact responses of hybrid iii atds in tactical vehicles. | although advanced restraint systems, such as seat belt pretensioners and load limiters, can provide improved occupant protection in crashes, such technologies are currently not utilized in military vehicles. the design and use of military vehicles presents unique challenges to occupant safety-including differences in compartment geometry and occupant clothing and gear-that make direct application of optimal civilian restraint systems to military vehicles inappropriate. for military vehicle envir ... | 2017 | 28095025 |
