Two new species of Neolebouria Gibson, 1976 (Digenea: Opecoelidae) from temperate marine fishes of Australia.

Neolebouria moretonensis n. sp. is described from Gerres subfasciatus (Gerreidae) from Moreton Bay, south-east Queensland and N. lineatus n. sp. is described from Centroberyx lineatus (Berycidae) from off Rottnest Island, south-west Western Australia. C. lineatus represents a new host family and order (Beryciformes) for the genus. The two new species are distinguished within the genus by their entire, tandem to oblique testes and cirrus-sacs that do not extend into the hind-body, by being less than 1 mm in length, and by the position of the genital pore and the relative size of the forebody and post-testicular region. N. lineatus and N. moretonensis are very similar but are distinguished by their caeca which extend further posteriorly in N. moretonensis. There is no apparent pattern in the host-specificity of this genus.

Allopodocotyle skoliorchis n. sp. (Opecoelidae: Plagioporinae) from Parequula melbournensis (Castelnau) (Gerreidae), a temperate marine fish in Australian waters.

A new species of Allopodocotyle Pritchard, 1966 is described from the intestine and pyloric caeca of Parequula melbournensis (Gerreidae) caught from the waters off South and Western Australia. The new species is distinguished from other species by its larger eggs, broader form, pre-bifurcal genital pore and a number of other measurable features that are discussed. Of the species that share morphological similarities with Allopodocotyle skoliorchis n. sp., it is the only species known from a gerreid; all the other species are from serranids.

Bartoliella pritchardae n. g., n. sp. (Digenea: Opecoelidae) in Epinephelides armatus (Serranidae) from temperate marine waters of Western Australia.

An opecoelid, Bartoliella pritchardae n. g., n. sp., is described from the intestine of Epinephelides armatus from Western Australia. The new genus has been assigned to the subfamily Opecoelininae Gibson & Bray, 1984, bringing the number of genera in the subfamily to two. Although the new genus is similar to Opecoelina Manter, 1934 morphologically, the pedunculate ventral sucker and complete absence of a cirrus-sac necessitate the erection of a new genus. A formal re-definition of the subfamily is given, based on the diagnoses of the genera Opecoelina and Bartoliella n. g.

A new species of Podocotyloides Yamaguti, 1934 (Digenea: Opecoelidae) from a Western Australian temperate marine fish.

A new species of Podocotyloides is described from Sillago bassensis caught off the coast of Western Australia. This is the second report of a species of this genus from Australian waters but the first of a new species. P. victori n. sp. is one of four species whose vitelline follicles extend into the forebody. It is distinguished from the other three species with vitelline follicles in the forebody by its relatively shorter forebody, smaller eggs and bipartite seminal vesicle. Pedunculotrema Fischthal & Thomas, 1970 is reduced to synonymy with Podocotyloides Yamaguti, 1934.

Mineral characteristics of leaves of plants from different phylogeny grown in various soil types in the temperate region.

The objective of this research was to analyze selected minerals in leaves of plants, belonging to 166 species growing in alluvial, low pH, brown forest and serpentine soils. Mineral characteristics of the soils involved were also determined. For the macronutrients, in trees grown in alluvial soil, N, P, Ca, and Mg concentrations of leaves were higher in recently evolved plants than in plants with a longer period of evolution; K concentration remained constant regardless of evolution. In grasses grown in alluvial soil, it was difficult to detect the general tendency of mineral concentration. N, P, and K concentrations in alluvial soil were closely related to those in low pH and serpentine soils. Ca concentration in alluvial soil was lower than that in low pH and serpentine soils. Mg concentration in alluvial soils was higher than that in low pH soils, while lower than that in serpentine soil. Therefore, N, P, and K accumulated according to the plant characteristics for these elements, while Ca and Mg accumulation was strongly affected by the soil properties. For the micronutrients, in trees, Fe and Mn remained constant regardless of evolution; Zn concentration was lower in recently-evolved plants than in plants with a longer period of evolution. In grasses, Fe, Mn, and Zn concentrations in Caryophyllids were high. Except for Caryophyllids, Fe and Cu concentrations remained constant. Mn concentration decreased with evolution, Zn concentration was higher in recently-evolved plants than in plants with a longer period of evolution.

Mineral characteristics of the leaves of 166 plant species with different phylogeny in the temperate region.

The P-N regression coefficient was moderate in Magnoliales, Coniferopsidae, Pteridophyta, and Asterids, but very high in Caryophyllids, and very low in Rosids. The K-N regression coefficient in trees remained constant regardless of evolution, and that in grasses was high except for Rosids compared with that in trees. The coefficient was very high in Caryophyllids and was very low in Rosids. The N-Ca and N-Mg relationship was not estimated at all, suggesting that the mechanism of Ca and Mg accumulation was completely different from that of N related accumulation. The Zn and Cu concentrations were related to the N concentration. The Al concentration in leaves was negatively correlated with the N, P, K, Ca, Mg, Na, Cu, Zn, Mn, and Fe concentrations, while the N, P, K, and Mn concentrations in leaves increased slightly with the increase of Al concentration in the high Al concentration. The Na concentration in leaves related negatively to the P, Ca, Cu, Zn, Mn and Al concentration range. Thus, it was demonstrated that most of the minerals in leaves accumulate negatively Al and Na indicating that there are antagonistic mechanisms for mineral accumulation in leaves among Al or Na and other mineral elements.

Anti-plaque effect of tempered 0.2% chlorhexidine rinse: an in vivo study.

OBJECTIVES: The aim of this in vivo study was to compare the anti-plaque effect of warm and cold chlorhexidine gluconate irrigation on matured human plaque. METHODS: In a split-mouth design, the antibacterial effect of 47 degrees C "warm" 0.2% chlorhexidine solution was compared with that of 18 degrees C "cold" rinse at the same concentration on newly-formed supragingival plaque that had been left undisturbed for 72 h. Before and 1 h after a 1-min rinse procedure, plaque was sampled from 10 test persons and vitality determined using vital fluorescence technique. RESULTS: Cold and warm 0.2% chlorhexidine solution reduced plaque vitality significantly from 99.63% to 77.81% (p=0.014) and from 98.98% to 51.77% (p<0.001), respectively. Rinsing with warm chlorhexidine solution reduced plaque vitality to a significantly greater degree (p=0.003) than did cold chlorhexidine. CONCLUSION: In this study, warm 0.2% chlorhexidine rinse showed a significantly more intensive anti-plaque effect than cold chlorhexidine solution at the same concentration.

Trait aggressiveness and hockey penalties: predicting hot tempers on the ice.

Previous studies examining the validity of measures of trait aggressiveness either have been retrospective studies or have used laboratory aggression as the criterion behavior. Can a measure of trait aggressiveness predict nonlaboratory physical aggression? The Physical Aggression subscale of the Aggression Questionnaire was completed by 91 high school hockey players prior to the start of the season. At the end of the season, these trait aggressiveness scores were regressed on minutes in the penalty box for aggressive penalties (e.g., fighting, slashing, tripping) and minutes in the penalty box for nonaggressive penalties (e.g., delay of game, illegal equipment, too many players). As expected, preseason trait aggressiveness scores predicted aggressive penalty minutes (r = .33) but not nonaggressive penalty minutes (r = .04).
