Influence of constant and changing temperature and humidity on the development and survival of the eggs and pupae of Drosophila melanogaster (Meigen)

Autor: J.N.R. Grainger, J. Aldrich, Z.Y. Al-Saffar

Publikováno v: Journal of Thermal Biology. 20:389-397

1. 1. The mean durations of development in the eggs and pupae of Drosophila melanogaster (Meigen) and their survival, were measured at combinations of six constant temperatures and up to eleven levels of vapour pressure deficit. 2. 2. Temperature was

The development rates of the egg and pupal stages of Drosophila melanogaster (Meigen) under changing conditions of temperature and humidity

Autor: J.N.R. Grainger, Z.Y. Al-Saffar, J. Aldrich

Publikováno v: Journal of Thermal Biology. 20:399-404

1. 1. The durations of development of eggs and pupae of Drosophila melanogaster (Meigen) (Diptera: Drosophilidae) were measured under two sets of changing conditions of temperature and humidity in the laboratory. 2. 2. In the first set, temperature a

The effect of temperature and other factors on the hatching of the resting eggs of Tanymastix stagnalis (L.) (crustacea, anostraca)

Autor: J.N.R. Grainger, Mona R. Al-Tikrity

Publikováno v: Journal of Thermal Biology. 15:87-90

1. 1|The conditions for the highest hatching of the resting eggs were found to be at temperatures between 10 and 15°C and in the presence of soil. Prior desiccation was found not to be essential for hatching. 2. 2|Hatching is steadily reduced follow

Factors affecting recovery of Dictyocaulus viviparus third stage larvae from herbage and growth of Pilobolus on dung pats

Autor: C.J. Somers, J.N.R. Grainger

Publikováno v: Research in Veterinary Science. 44:147-153

Significantly greater Dictyocaulus viviparus stage three larval recoveries from herbage samples adjoining first stage larval infected dung pats with Pilobolus, and the effects of biotic and mechanical factors on dung pat integrity supported previous

The effects of constant and changing temperatures on the period from egg hatching to egg laying in Tanymastix stagnalis

Autor: J.N.R. Grainger

Publikováno v: Journal of Thermal Biology. 6:353-356

The main duration of time from egg hatching to egg laying (D) in this anostracan crustacean increases at lower constant temperatures. The mean number of eggs per female lay between 25 and 50. In both regularly changing temperature experiments D was s

The effect of constant and changing temperatures on the thermal resistance of Lymnaea peregra (Müller)

Autor: O.A.M. Al-Habbib, J.N.R. Grainger

Publikováno v: Journal of Thermal Biology. 2:191-195

The effect of constant and changing temperatures on both high and low lethal temperatures of Lymnaea peregra and the time course of acclimation were investigated. Snails acclimated to 6.5°, 11.5° and 16.5°C showed paradoxical ‘adaptation’ of t

The effect of constant and changing temperatures on the development of the eggs and larvae of Ostertagia circumcincta

Autor: Nabeel E. Salih, J.N.R. Grainger

Publikováno v: Journal of Thermal Biology. 7:35-38

1. 1.|The rates of development of O. circumcincta eggs have been determined over a range of constant temperatures. Two changing temperature regimes had no extra effect on development rate. 2. 2.|The rate of development of larvae from hatching from th

A model of a growing steady state system

Autor: J.N.R. Grainger, L. Bass

Publikováno v: Journal of Theoretical Biology. 10:387-398

A theoretical treatment is given of an enlarging steady state system consisting of a single enzyme catalysed reaction. It is shown that if this was “grown” logarithmically a steady state of growth is set up which is different from the steady stat
