Stormwater Retention

Throughout the 2004 mosquito season, 52 stormwater retention facilities were sampled to characterize the seasonal occurrence and relative abundance of mosquito species in relation to the structural complexity and biological diversity of the facilities. The three different types of facilities included standard wet ponds (n=20), innovative ponds (n=14), and wetland ponds (n=18). All retention structures were sampled at the beginning, middle and end of the mosquito season so that seasonal changes in mosquito production could be characterized. Overall samplings, mosquitoes were collected from 34% of the retention structures. Fourteen species representing 7 genera were collected, but only 5 species (Culex erraticus, Cx. territans, Anophelesquadrimaculatus, An. punctipennis and Uranotaenia sapphirina) were commonly collected in all three types of stormwater management facilities. In general, the seasonal prevalence and relative abundance of mosquito species did not vary among three types of retention structures. A significant association (P<0.01) between the presence of mosquito larvae or pupae and the absence of mosquitofish was found for innovative and wetland stormwater retention facilities but not for standard retention facilities (P>0.05).

AbstractI evaluated bat assemblages in terms of species richness, relative abundance, trophic guild structure, and seasonal changes at three sites along of the Southern Yungas forests. A total of 854 individuals were captured, representing 25 species of three families, with an effort of 27,138 m of mist net opened per hour. Subtropical assemblages showed a similar structure to those from tropical landmark, with a dominance of frugivorous Phyllostomid; in addition, a few species were abundant, followed by a long tail of less common species. However, subtropical sites differed due to the dominance of the genus

Blood Cell Morphology

Abstract The morphology of erythrocytes, trombocytes, monocytes, basophils and lymphocytes on Moorish geckos (Tarentola mauritanica) is quite similar to that of other reptiles, even though some peculiarities were detected for heterophils and eosinophils. Moreover, we found a fourth type of granulocyte whose morphology highly differs from both heterophils and eosinophils. Sexually-based differences in the relative abundance of different types of leukocytes was detected: lymphocytes were the most frequent in females, while heterophils and eosinophils prevailed in males. Interestingly, in most individuals we found intra-erythrocytic vacuoles whose structure is similar to that previously described as Chelonoplasma in tortoises and Serpentoplasma in snakes.

Aerial surveys of coastal waters (27 216 km2) in the western Gulf of Carpentaria during the dry season of 1984 and wet season of 1985 indicated no major seasonal changes in distribution and relative abundance of dugongs. Minimum population size in the dry season was estimated as 16 816 � 2946 (standard error), with a relative density of 0.62 k 0.11 km-2, and that for the wet season 16 846 + 3257, with a relative density of 0.62 � 0.12 km-2. The estimates exclude 5% of observations which could have been either dugongs or Irrawaddy dolphins, and were corrected for submerged dugongs and those missed on the surface. Dugongs were unevenly distributed over the study area, and neither mean group size nor proportion of calves varied between seasons. Dugong abundance was correlated with area of available seagrass. The catch rate of dugongs by Aboriginal people off Numbulwar decreased six-fold between the 1960s and 1985 (60 to 10 p.a.), possibly due to excessive hunting.

A New Species

The microbial population in the rhizosphere of wheat, oats, alfalfa, and peas was studied and the relative abundance of different types of micro-organisms recorded. By means of the plating method it was found that bacteria and actinomycetes were 7 to 71 times greater in the rhizosphere than in the soil distant from the roots, whereas fungi were but 0.75 to 3.1 times more numerous.Different varieties of plants affected the activity of the various groups of soil micro-organisms differently. Thus fungi were more numerous in the rhizosphere of oats, and bacteria in the rhizosphere of alfalfa. Seventeen genera of fungi were represented in isolates from the rhizosphere of seedlings and the soil distant from the roots. However, no marked difference was observed in the types isolated from the rhizosphere of different varieties of seedlings. A fungus isolated from the rhizosphere of alfalfa proved to be a new species and the genus Spicularia Persoon was amended to include it.

Trentepohlia Martius, a dominant green subaerial alga, grows abundantly in Shillong and imparts the yellow, red, and orange colours to most of the tree barks, walls, rocks, and electric poles because of high accumulation of carotenoids in their filaments. This study emphasised the seasonal changes in carotenoid content amongst four different species of Trentepohlia, that is, T. diffracta, T. arborum, T. umbrina, and T. abietina, collected from four different substrata, that is, wall, rock, electric pole, and three types of tree bark (smooth, fissured, and rough). Quantitative estimation of different carotenoids, namely, β-cryptoxanthin, lutein, and β-carotene, from HPLC chromatogram peak showed a significant seasonal variation in all of the four species and β-carotene was threefold more in winter compared to summer. Amongst the selected species, T. diffracta collected from wall contained the highest amount of β-carotene both in summer and in winter, followed by T. arborum from rock and T. abietina from bark, and least amount was in T. umbrina collected from electric pole. Comparing the carotenoid content in Trentepohlia abietina growing in different types of barks, sample from smooth bark had the highest amount of carotenoids both in summer and in winter, followed by the sample from rough bark, and lowest amount was noted in fissured bark.

Important Significance

Stormwater is a resource, but the traditional stormwater management practices treat it as a waste and cause many problems. Green Street is a new method to manage the street stormwater runoff through the landscape architecture application. By analyzing the origin, definition and function of the Green Street, it can draw a conclusion that the Green Street originates from America, it is a street that uses natural process to manage stormwater runoff at the source, and it can improve street water environment, create attractive streetscape, enhance neighborhood livability, etc. Also, the Green Street has five different types, including stormwater curb extension, stormwater planter, stormwater swale, pervious paving and infiltration garden. Finally, through analyzing two examples of Green Street application in Portland, Oregon, it proved that Green Street is a high effective and low-cost method to manage the street stormwater runoff. In brief, Green Street will have increasingly important significance for the street stormwater management when it is used widespread gradually.
