Life-table analysis of Anopheles malaria vectors: generational mortality as tool in mosquito vector abundance and control studies [PDF]

open access: yes, 2005
Background & objectives: Vector control will for sometime remain a primary weapon in the waragainst vector borne diseases. Malaria is of paramount importance in this with its associated highmorbidity and mortality especially in sub-Saharan Africa.

The effects of temperature and oxygen availability on intracapsular development of Acanthina monodon (Gastropoda: Muricidae) El efecto de la temperatura y la disponibilidad de oxígeno sobre el desarrollo intracapsular de Acanthina monodon (Gastropoda: Muricidae)

open access: yesRevista Chilena de Historia Natural, 2006
Freshwater and marine organisms show similar models of parental care and are faced with similar constraints to brood, which suggest that comparable environmental limits drive the evolution of parental care in aquatic systems.

Geographic variation in the response of Culex pipiens life history traits to temperature [PDF]

open access: yes, 2016
BackgroundClimate change is predicted to alter the transmission of many vector-borne pathogens. The quantitative impact of climate change is usually estimated by measuring the temperature-performance relationships for a single population of vectors, and ...

The evolutionary ecology of sibling cannibalism in the wild

open access: yes
Sibling cannibalism is common amongst animals. Whilst the role relatedness plays in this behaviour has been well studied due to the strong ties between cannibalism and evolutionary theory, we lack enough knowledge of the ecology underlying this behaviour to properly explain its evolution.

Sex-dependent effects of sibling cannibalism on life history traits of the ladybird beetle Harmonia axyridis (Coleoptera: Coccinellidae) [PDF]

open access: yesBiological Journal of the Linnean Society, 2002
To investigate the sex-dependent effects of sibling cannibalism on variations in life history traits, I analysed body size, weight and instar interval in relation to the occurrence of sibling cannibalism in the ladybird beetle Harmonia axyridis. Sibling cannibalism at the time of hatching significantly affected the body size and weight of adults. There

Differential effects of offspring condition-dependent signals on maternal care regulation in the European earwig [PDF]

open access: yes, 2018
Parent-offspring conflict theory predicts the evolution of offspring solicitation signals that can influence the amount and/or the duration of parental investment.

Estimated un-ionized ammonia at small incremental pH value and temperatures: practical option for fish farmers [PDF]

open access: yes, 2012
Ammonia as the primary product of nitrogen metabolism causes mortality due to ammonia toxicity produced in a culture system. Effect of pH and Temperature was calculation and expanded using the acid dissociation constant (pka) for equation: pka = 0.09018+
