Correlation between annual activity patterns of venomous snakes and rural people in the Niger Delta, southern Nigeria
Akani Godfrey C,Ebere Nwabueze,Franco Daniel,Eniang Edem A
Journal of Venomous Animals and Toxins including Tropical Diseases , 2013, DOI: 10.1186/1678-9199-19-2
Abstract: Background Venomous snakes are among the most serious health hazards for rural people in tropical regions of the world. Herein we compare the monthly activity patterns of eight venomous snake species (Elapidae and Viperidae) with those of rural people in the Niger Delta area of southern Nigeria, in order to identify the periods of highest potential risk for persons, and the human group actually at greater risk of snakebite. Results We documented that above-ground activity of all venomous snakes peaked in the wet season, and that high snake activity and high human activity were most highly correlated between April and August. In addition, we documented that women and teenagers were at relatively higher risk of encountering a venomous snake than adult males, despite they are less often in the field than men. Conclusions Our results suggest that future programs devoted to mitigate the social and health effects of snakebites in the Niger Delta region should involve especially women and teenagers, with ad-hoc education projects if appropriate. We urge that international organizations working on social and health problems in the developing world, such as IRD, DFID, UNDP, should provide advice through specific programs targeted at especially these categories which have been highlighted in comparatively potential higher threat from snakebites than adult men.

Abstract: è stato studiato l'intero popolamento mammaliano, attraverso le catene trofiche, lungo un mega transetto che percorre oltre 1.500 Km lineari attraverso il mosaico foresta-piantagione con locale introgressione di foresta costiera di mangrovie e savana di Guinea, tra la Nigeria e il Camerun, due hot-spots per la biodiversità mammaliana come esempio di un popolamento afro-tropicale-occidentale. Sulla base delle nostre decennali investigazioni, risulta che esiste una sola specie di superpredatore di I grado (Python sebae), una di II grado (Panthera pardus), e, in particolare tra i mammiferi, una serie di predatori intermedi, come, ad es. Genetta spp., etc. Il rapporto numerico tra superpredatori e predatori tende a decrescere da est verso ovest, dai rilievi verso le pianure, e dagli ecosistemi frammentati fino a quelli omofitici, e, in sostanza, dalla foresta temporaneamente allagata alla mangrovia secondaria. Non ultima, grossa influenza viene attribuita alla distribuzione delle ingressioni salmastre che modellano la canopia e le sue "keystone species". Di particolare rilevanza ecologica risulta la debole correlazione che lega la presenza di superpredatori e predatori generalisti con specifiche prede "target", cioè a dire che la predicibilità della presenza-assenza di un determinato taxon predatore è scarsamente rilevata dalla comunità delle prede. Tutto ciò sembrerebbe logicamente derivare dall'azione delle popolazioni cacciatrici native che quindi equivarrebbero funzionalmente a dei superpredatori e predatori generalisti, che per loro stessa natura, non potrebbero essere tollerati dal carico corrente dell'ambiente residuo.

Pakistan Journal of Nutrition , 2009,
Abstract: The proximate composition ,ascorbic acid and Heavy metal contents of two species of Garden egg, Solanum gilo and Solanum aubergine were evaluated using chemical analysis. The result of the proximate composition analysis showed that solanum gilo fruits had the following composition:moisture (74.80%), carbohydrate (52.13%), crude protein (14.87%), crude fibre (16%), crude fat (7%) and ash (10%). It also contained (93.7%) of ascorbic acid. The Solanum aubergine fruits on the other hand contained moisture (94.6%), carbohydrate (58.5%), crude protein (15.75%), crude fat (4%), crude fibre (11.75%) and ash (10%). It also contained (75.9%) ascorbic acid. The Heavy metal concentrations of Solanum gilo fruits are Zn (3.81ppm), Cr (1.74ppm), Cd (0.16ppm), Cu (1.48ppm), Co (0.12ppm) and Hg (0.01ppm). The solanum aubergine fruits on the other hand contained Zn (1.58ppm), Cr (2.45ppm), Cd (0.77ppm), Cu (0.04ppm), Co (0.10ppm) and Hg (0.01ppm). The concentrations of As and Pb in the fruits of both species were not detected. The result Shows that the values of moisture, ascorbic acid, crude fibre and crude fat were higher in S. gilo fruits, while the values of carbohydrate and crude protein were higher in S. aubergine fruits. The result also showed that the fruits of both species have same ash content. The result revealed that the concentrations of Zn, Cu and Co were higher in S. gilo fruits, while S. aubergine fruits has higher values of Cr and Cd. The results also revealed that the concentrations of Cr and Cd in both species of the plant were all above WHO permissible limits of 0.05ppm and 0.005ppm, respectively.

Ethiopian Journal of Environmental Studies and Management , 2008,
Abstract: A year long markets survey of bush meat trade and consumption was organized to assess the volume and components of bush meat trade in the Oban Hills region of Cross River State, Nigeria with the specific objectives to determine (types and kinds) or species of animals (especially primates) involved in the bush meat trade and investigate their sources, quantity, prices and trends in trade as well as seasonal variations in bush meat (primate) supplies and order to determine their implications for sustainable livelihoods and conservation while creating awareness on need for sustainable harvesting and conservation of wildlife among the operators of bush meat trade and consumptive activities. Reconnaissance surveys, intensive dry and wet season markets survey using formal and informal investigative carcass examination and bargaining to inspect and price bush meat. Results show that bush meat trade is growing at an alarming rate with increasing number of hunters and traders, driven by profit motive and destructive consequences on the population of all categories of vertebrate fauna including endangered species. The paper calls for the adoption of the provisions of the Convention on Biological Diversity (CBD) of the United Nations by Nigerian government to safeguard the sustainable livelihoods and biodiversity of the nation.

Ethiopian Journal of Environmental Studies and Management , 2008,
Abstract: Intensive field based African grey parrots (Psittacus erithacus) trade and trafficking survey lasting 14 days was undertaken on the request of the Pheasant Conservation Group; International Union for the Conservation of Nature and Natural Resources (IUCN), to determine the existence or non-existence of parrots trapping, trade and trafficking in the Ikpan Forest Block of Oban group of forest, Nigeria. The surveys which identified and involved occupational parrots' trappers as guides was pursued with a view to identifying Nest sites, Nest density, Parrot roosts as well as investigate parrots trapping, trade and trafficking in the light of Nigeria's biodiversity conservation policy thrust and the country's continued notoriety in the international conservation arena . Studies were conducted using standard field equipment like binoculars, photo camera, vinyl flagging, field camping equipment as well as protective wears. 5 occupational Parrot trappers (2 experienced and 3 trainees) were identified and recruited for the surveys as field guides, field assistants and porters. From the results, 5 trappers' stations were identified and explored and located on existing map. Practical trapping activities were observed and implements employed identified. Parrot catch per Man-day was 8 (range 4-12) and price per wild adult parrot N2000, range (N2500-4500) while trained parrots costs N5000 (range N10, 000 - 15,000). During the surveys 16 parrots were captured while 50 parrots (range 110 - 160) were seen flying overhead especially at dusk. It was discovered that trade and trafficking in parrots existed in the study area and beyond with birds coming in from various localities and sold at major cities of Calabar, Port Harcourt, Lagos, Abuja and Kano. Ineffective wildlife legislations have contributed to escalating illegal trade and trafficking in parrots which are protected by states and national laws. Effective legislation, monitoring, habitat protection and conservation education are recommended for sustainable biodiversity conservation in Nigeria.

Pakistan Journal of Social Sciences , 2012,
Abstract: The primary aim of this study, was to find out the knowledge, attitude and preventive practices towards pregnancy induced hypertension among pregnant women in General Hospital Calabar, Cross River State, Nigeria. The research was made based on the following research questions: what is the level of pregnant women s knowledge about pregnancy induced hypertension? What are the pregnant women s attitude and believes about pregnancy induced hypertension? The population involved a total of 200 pregnant women and a sample of 100 pregnant women were used for the study. The research instrument used in data collection was a questionnaire which was administered to 100 pregnant women. Their responses were analysed using descriptive statistics. The study showed that, about 82% of the women had formal lecture on pregnancy induced hypertension, hence have knowledge of pregnancy induced hypertension. Eighty percent of the women visit the hospital on noticing that they have swollen legs, 84% of the women believes that pregnancy induced hypertension could be prevented through regular antenatal care. Therefore, the study showed a positive correlation between adequate knowledge and positive attitude as the condition could be prevented.

Pakistan Journal of Nutrition , 2009,
Abstract: Two sets of samples of commercially important fish species Oreochromis niloticus of size 29 cm and 20 cm respectively were purchased from the Henshaw town beach market in Calabar, Calabar South Local Government Area of Cross River State, Nigeria in October 2007. The concentrations of five heavy metals (Pb, Zn, Cd, As and Hg) in their bones, gills, livers and muscles were determined using flame atomic absorption spectrophotometer. The result showed the heavy metal concentrations in the 29 cm size samples to be Pb (0.069 ppm) Cd (0.019 ppm) and Zn (0.103 ppm) in the bones. Pb (0.173 ppm) Cd (0.049 ppm) and Zn (0.257 ppm) in the livers. Pb (0.053 ppm) Cd (0.015 ppm) Zn (0.079 ppm) in the muscles Pb (0.133 ppm), Cd (0.038 ppm) and Zn (0.198 ppm) in gills. While the 20 cm size samples had Pb (0.067 ppm) Cd (0.019 ppm) and Zn (0.100 ppm) in bones. Pb (0.067 ppm) Cd (0.019 ppm) and Zn (0.099 ppm) in livers. Pb (0.062 ppm) Cd (0.017 ppm) and Zn (0.095 ppm) in muscles and Pb (0.153 ppm) Cd (0.044 ppm) and Zn (0.227 ppm) in gills. Arsenic and mercury were not detected in any of the samples. The result revealed the distribution of the heavy metal in both 29 cm and 20 cm size samples to follow the order Zn> Pb> Cd while the distribution of the heavy metals in the investigated parts (organs) is shown to follow the order livers > gills > bones > muscles for the 29 cm size samples. And Gills > Livers = bones > muscles in the 20 cm size samples. The result also revealed that the 29 cm size samples had higher concentrations of the heavy metals than the 20 cm size samples. The result also showed that the muscle of Tilapia is safer to consumed than the other parts investigated as it has been shown to contain the least concentrations of the heavy metals determined. This reveals the adverse health effect the people in the study area could be exposed to by the consumption of liver, gills and bones of Tilapia which have high levels of these heavy metals.

Pakistan Journal of Nutrition , 2009,
Abstract: The proximate composition, ascorbic acid and heavy metal content of (African walnut) Tetracarpidium conophorum were evaluated using chemical analysis. The result of the proximate composition showed the following; moisture (48.70%), carbohydrate (53.20%), crude protein (35.22%), crude fat (6.21%), crude fiber (3.34%) and ash (2.03%).It also contained 53.50mg/100ml of ascorbic acid. The heavy metal concentrations in the fruit is Fe (0.064ppm), Mn (0.012ppm), Cr (0.001ppm), Ni (0.005ppm) while the concentrations of Hg, Pb and Cd were not detected. The results revealed that the T. conophorum is rich in ascorbic acid and carbohydrate with moderate valves of crude protein while the ash content was shown to be very low. This result shows that T. conophorum nut is not polluted with heavy metals since the concentrations of the heavy metals were all below WHO permissible limits. This nut is therefore shown to be safe for public consumption.
