Secondary Production and Organic Matter Processing by Collector Macroinvetebrates in a Desert Stream
Secondary production (measured as dry mass) of collector macroinvertebrates of Sycamore Creek, Arizona, estimated by the size-frequency method, is 135 g m-2. yr-'. This high rate of production is attributed to a long growing season, continuous reproduction, rapid life cycles of major taxa, and small size at maturity. Assimilation efficiency for selected collector taxa is estimated to be 7-14% a...
متن کاملPerformance of Single Pass Down Stream Solar Air Collector with Inclined Multiple V-Ribs
Solar air heater is a type of heat exchanger which transforms solar radiation into heat energy. The thermal performance of conventional solar air heater has been found to be poor because of the low convective heat transfer coefficient from the absorber plate to the air. It is attributed to the formation of a very thin boundary layer at the absorber plate surface commonly known as viscous sub-la...
متن کاملEvaluation of water quality of an urban stream in southeastern Brazil using Chironomidae larvae (Insecta: Diptera).
In order to estimate the water quality of São Pedro stream, through distribution and composition of Chironomidae larvae present in the sediment four sampling sites were selected. In each sampling site, three sediment samples were collected within a period of twelve months using the Petersen (0.0189 m²) and the van Veen (0.0518 m²) dredges. Samples were washed through a sieve with a 0.21 mm mesh...
متن کاملVisceral urate deposition in a little bittern (Ixobrychus minutus)
Visceral urate deposition (visceral gout) is a common finding during post-mortem examination of poultry. Rare cases of visceral gout may occur in wild birds. A rare case of visceral urate deposition in a little bittern (Ixobrychus minutus) is reported here. In May 2013, carcass of a little bittern was submitted for necropsy to the Clinic of Poultry Diseases (Faculty of Veterinary Medic...
متن کاملA Generalized Coupon Collector Problem
This paper provides analysis to a generalized version of the coupon collector problem, in which the collector gets d coupons each run and he chooses the one that he has the least so far. In the asymptotic case when the number of coupons n goes to infinity, we show that on average n log n d + n d (m−1) log log n+O(mn) runs are needed to collect m sets of coupons. An efficient exact algorithm is ...
