A vast body of work exists on the endocrine regulation of frog metamorphosis ( Dodd and Dodd 1976 , Shi 1999 , Denver et al. 2002 , Buchholz et al. 2006 , Furlow and Neff 2006 , Brown and Cai 2007 ), and a separate set of literature describes the dramatic larval period diversity found among amphibians ( Duellman and Trueb 1994 , McDiarmid and Altig 1999 ). This chapter begins to unite these top...

Microbial flora of portuguese chouriço (Alentejano (A) and Ribatejano (R)) with abnormal sensorial characteristics along shelf life was studied. Mesophilic anaerobic bacteria, enterococci, mesophilic sporeformers, coliforms, coagulase-positive staphylococci, sulphite reducing clostridia, Clostridium perfringens, moulds and yeasts were the most representative in both types of chouriço.

a castanea crenata agglutinin (abbreviated as cca) was extracted and purified from bitter apple, citrullus colocynthis l., to determine its effects on the demographic parameters of apomyelois ceratoniae zeller. two groups of first larval instars were reared on an artificial diet containing 2% (w/w) of cca and control diets until emergence of adults. two sex ms-chart life table software was used...

Marine seafloor ecosystems, and efforts to restore them, depend critically on the influx and settlement of larvae following their pelagic dispersal period. Larval dispersal and settlement patterns are driven by a combination of physical oceanography and behavioral responses of larvae to a suite of sensory cues both in the water column and at settlement sites. There is growing evidence that the ...

This study was carried out in a completely randomized design 3×3×4 factorial arrangement in three periods of rearing in spring 1997. Density of 300 larvae was assigned for each oval tank with 0.1m2 surface area, 30cm deep, a volume of 20lit and 0.25 lit/min of water flow per minute at Shahid Rajaie fish breeding and culture center in Sari, north of Iran. The fries were divided into ...

Extracts and purified extracts of seeds of two plant species, Madhuca latifolia and Calophyllum inophyllum when evaluated against the 2nd instar larvae of Helicoverpa armigera reared on synthetic diet, exhibited high larval mortality, prolongation of developmental period, morphological deformities and highly significant reduction in adult emergence. The reduction in larval weights in the treatm...

the spotted amber ladybird, hippodamia variegata (col.: coccinellidae) is one of the most prominent coccinellid predators in iran. it is omnivorous and feed on aphids and psylla. the effects of two diets brevicoryne brassicae l. (hemiptera: aphididae)and eggs of ephestia kuehniella (lepidoptera: pyralidae) on some biological aspects of hippodamia variegata (goeze) (coleoptera: coccinellidae) we...
