Abstract Aim Squamate fitness is affected by body temperature, which in turn influenced environmental temperatures and, many species, exposure to solar radiation. The biophysical drivers of temperature have been widely studied, but we lack an integrative synthesis actual experienced the field, and their relationships temperatures, across phylogeny, behaviour climate. Location Global (25 countries on six continents). Taxa Squamates (210 representing 25 families). Methods We measured 20,231...
The present study was aimed at evaluating the effects of different concentrations most commonly used fish antimicrobial drug, chloramphenicol (CAP), on behavior and hematological parameters Clarias gariepinus. Fish specimens were exposed to three (2.5, 5.0 10.0 mg L(-1)) sublethal CAP a control. Abnormal behavioral changes observed in higher concentration CAP. Blood erythrocytes sampled days 1, 5, 10 15 postexposure evaluate parameters. Results showed concentration- time-dependent...
The fruit extract of Dacryodes edulis (D. edulis), the African pear or plum, a tree indigenous to humid tropics has been used for managing wounds, skin diseases, sickle cell anaemia, dysentery and fever in some nations. In South Eastern Nigeria, 'herbal doctors' include its marshed decoctions administered diabetic patients. However no scientific substantiation their claim use exist literature. Hence, need evaluate antidiabetic hypolipidaemic activity hexane extracts D. alloxanised animal...
The survival of land snails in an adverse environmental condition depends on the integral physiological, morphological and behavioural adaptations. These adaptations are essential understanding species-specific habitat requirements predicting their responses. In this study, monthly periodic patterns eco-physiological adaptation snail, Achatina achatina Nsukka tropical agro-ecosystem were assessed from December 2012 to July 2013. Standard methods employed sampling snail determination water...
Understanding the interaction between upper voluntary thermal limit (VTmax) and water loss may aid in predicting responses of ectotherms to increasing temperatures within microhabitats. However, temperature at which climate heating will force cool-climate, nocturnal lizards abandon daytime retreats remains poorly known. Here, we developed a new laboratory protocol for determining VTmax retreat-dwelling, viviparous Woodworthia “Otago/Southland” gecko, based on escape behaviour (abandonment...
Abstract High-latitude lizards live in environments where ambient air temperature at night is frequently below retreat temperatures, which likely has implications for nocturnal emergence and activity. However, patterns of lizard activity under current temperate climates are poorly understood, a situation that limits our understanding potential effects climate change. We investigated the cold-adapted, viviparous gecko (Woodworthia ‘Otago/Southland’). measured operative environmental (Te)...
Mucuna sloanei is an annual leguminous plant widely used among the various ethnic groups in Nigeria. The effects of aqueous M. seed extract on body weight and some biochemical parameters 48 normal male Rattus novergicus (albino rats) were investigated for 28 days. rats divided into control group (A) which received distilled water treatment (B, C D) that oral administration 100, 200 400 mg/kg extract, respectively. Each was further three replicates four each. Blood samples collected before...
Mucuna sloanei is a legume used as soup thickener by communities in some parts of Africa countries. The effect aqueous seed extract M. on the haematological profile normal albino rats was investigated for 28 days using standard methods. results show no overall dose dependent significant difference (p > 0.05) serum levels white blood cell count, red count and its indices (haemoglobin content, pack volume, mean corpuscular haemoglobin concentration) throughout duration experiment when...
Genetic engineering, which is synonymous to genetic modification, the designed alteration of make-up an organism and it basis for modern biotechnology.on other hand, biotechnology application science in production goods services using biological agents.The cell functional unit life contains two kinds nucleic acids: Deoxyribonucleic acid (DNA) Ribonucleic (RNA).While DNA material, RNA functions protein synthesis.The tools method modification include; gene insertion, deletion...
Comparisons of sympatric species inhabiting the same ecological habitat may elucidate adaptive processes. We studied physiological patterns two genus Limicolaria (L. aurora and L. flammea) that thrive in a hot tropical habitat. examined changes water content, biochemical fuel reserves haemolymph enzyme activities during aestivation activity. Our results indicate both had potential to conserve body aestivation. A definite pattern foot muscle was observed. Both depleted glycogen while building...
