SUMMARYA field plot experiment of 271 days duration was conducted on New Zealand irrigated pastures, commencing in the summer (January) 1988, on a Templeton silt loam soil (Udic Ustochrept) by applying 35sulphur (35S)-labelled urine (250 μCi/g S with 1300 μg S/ml) to field plots (600 × 600 mm) at a rate equivalent to that normally occurring in sheep urine patches (150 ml/0·03 m2) to investigate the distribution, transformations and recovery of urinary S in pasture soil–plant systems and sources of plant-available soil S as influenced by the available soil moisture at the time of urine application and varying amounts of applied irrigation water. Results obtained showed that c. 55–90% of 35S-labelled urine was incorporated into soil sulphate (SO42−), ester SO42− and carbon (C)-bonded S fractions within the major plant rooting zone (0–300 mm), as early as 27 days after urine application. Hydriodic acid (Hl)-reducible and C-bonded soil S fractions showed no consistent trend of incorporation. On day 271, labelled-S was found in soil SO42−, Hl-reducible S and C-bonded S fractions to a soil depth of 500 mm, indicating that not only SO42− but also organic S fractions from soils and 35S-labelled urine were leached beyond the major rooting zone. A large proportion (c. 59–75%) of 35S-labelled urine was not recovered in pasture soil–plant systems over a 271-day period, presumably due to leaching losses beyond the 0–300 mm soil depth. This estimated leaching loss was comparable to that (75%) predicted using the S model developed by the New Zealand Ministry of Agriculture. The recovery of urinary S in soil–plant systems over a 271-day period was not affected by different amounts of irrigation water applied 7 days after urine application to soil at either 50 or 75% available water holding capacity (AWHC). However, significantly lower S recovery occurred when urinary S was applied to the soil at 25% AWHC than at field capacity, suggesting that urinary S applied at field capacity might not have sufficient time to be adsorbed by soil particles, enter soil micropores or be immobilized by soil micro-organisms. Both soil ester SO42− and calcium phosphate-extractable soil S in urine-treated soils were found to be major S sources for pasture S uptake. Labelled S from 35S-labelled urine accounted for c. 12–47% of total S in pasture herbage.

Two New Species

Two new species, Prolixus nicholasi sp. nov. and Prolixus setifolius sp. nov., are described and illustrated from leaves of Gahnia setifolia (Cyperaceae) in Auckland, New Zealand. In this paper, we present the ontogenetic additions in idiosomal and the leg chaetotaxy from larva to adult. The adult male and female of P. setifolius have different leg setae, allowing all active life stages to be sexed. A key to world species of Prolixus is also proposed.

Phocarctos Hookeri

The New Zealand sea lion (NZ sea lion), Phocarctos hookeri, is New Zealand’s only endemic pinniped, and one of the worlds rarest otariids. It is classified as ‘Threatened’ based primarily on the low number of breeding sites and restricted distribution. In New Zealand, a species listed as ‘threatened’ is required to be managed to allow its recovery and removal from the list within 20 years. For NZ sea lions this is dependant on the establishment of new breeding areas. However, understanding the recolonisation processes for pinnipeds is still in its infancy with factors such as philopatry needing more research to understand individual dispersal and the recolonisation process. This paper presents the first quantitative investigation into the level of site fidelity and philopatry to breeding beaches in NZ sea lions. Data from resights of NZ sea lions marked as pups from the northern Auckland Island breeding area suggest that both site fidelity and philopatry are important characteristics of this species. Our results show that overall: (1) females have a higher resighting rate than males, particularly at natal sites; (2) female non-natal resightings are predominantly restricted to locations within the northern Auckland Island breeding area (an area of ~10 km2), whereas male resightings are more widely dispersed (up to 700 km to NZ mainland); and (3) philopatry occurs for both sexes, but is more predominant in females than males, with males displaying delay related to sexual and social maturity. The colonisation of new breeding habitats rarely occurs when philopatry is strong and population density is low, stable or declining such as seen for NZ sea lions. Therefore, this research indicates that management of NZ sea lions needs to minimise anthropogenic mortality and encourage population growth to maximise density at breeding sites and encourage females to disperse to establish new breeding areas.

A 2-year lysimeter study was conducted to determine the fate of nitrogen in pig slurry applied to a moderately fertile, semi-free-draining pasture soil in the Canterbury Plains of New Zealand. Pig slurry was applied annually for 2 years in autumn, at 3 rates of 0, 200, and 400 kg N/ha to 12 large soil lysimeters (4 at each rate), 800 mm in diameter by 1200 mm deep. Slurry applied in Year 1 was labelled with 15N and a mass balance obtained at the end of the experiment. The mass balance showed that over the 2 years following application of 15N-labelled slurry, 8–19% was lost in the leachate, 20% was removed in the cut pasture, 15–26% was lost via volatilisation, 14–18% remained in the roots and soil, and approximately 30% was lost by denitrification. The high denitrification loss was attributed to (i) a large soil concentration of nitrate supplied from nitrification of the ammonium-N in the slurry; (ii) a readily oxidisable source of carbon supplied in the slurry; and (iii) transient anaerobic conditions produced by textural discontinuities and impeding layers within the soil profile. The fate of applied nitrogen between years was affected by the pattern of water inputs (rainfall and irrigation) and the resulting effect on drainage. Concentrations of inorganic nitrogen in the leachate from the 200 kg N/ha·year treatment were found to be consistently below 25 mg N/L, but those from the 400 kg N/ha·year treatment were considerably higher (c. 65 mg N/L) and persisted for a prolonged period. The latter N concentration represented a significant loss of nitrogen over the study period and may be of environmental concern.

Two Australian species of Polynema Haliday (Hymenoptera: Mymaridae), P. (Polynema) draperi Girault and P. (Polynema) editha Girault, are redescribed, as is the Australasian and Oriental P. (Dorypolynema) mendeli Girault; the previously unknown female of P. draperi and male of P. editha are also described. One new species group, the draperi group, is newly defined in P. (Polynema), in which eight new species are described: P. (Polynema) aristokratka sp. n. (New Zealand), P. (Polynema) baronessa sp. n. (New Zealand), P. (Polynema) grafinya sp. n. (New Zealand), P. (Polynema) imperatrix sp. n. (Australia), P. (Polynema) koroleva sp. n. (New Zealand), P. (Polynema) markiza sp. n. (New Zealand), P. (Polynema) princessa sp. n. (Australia), and P. (Polynema) rangatira sp. n. (New Zealand). Keys to the two treated subgenera of Polynema, both sexes of the world species of P. (Dorypolynema Hayat & Anis), and to females of the 10 described P. (Polynema) species in Australia and New Zealand are given. Taxonomic notes are provided for the Afrotropical species Polynema (Dorypolynema) mboroense (Risbec), comb. n. from Acmopolynema Ogloblin, whose previously unknown female is described, and for the Australian species Palaeoneura frater (Girault), comb. n. from Polynema.

Small Genus

Acaricis Beard and Gerson (Acari: Tenuipalpidae) is a small genus of flat mites with three species described from Australian and New Zealand sedges (Poales: Cyperaceae). In this article, we redescribe two species, Tenuipalpus montanus Collyer and T. alpinus Collyer, and move them to the genus Acaricis, so that these species become Acaricis montanus (Collyer) comb. nov. and A. alpinus (Collyer) comb. nov.. These two species share several characters with other Acaricis that species of Tenuipalpus do not. A key to the world species of Acaricis is also proposed.
