Captive Rearing

The impact of captive rearing of snails (Archachatina marginata) on the bio-accumulation of some heavy metals (HMs) (Fe, Mn, Cu, Pb, Co, Ni, Cd and Cr) in the meat and haemolymph was evaluated in a two treatment trial (snails from the wild, (SW) and captive reared snails, (SC), each comprised of sixty snails of three replicates. Alldata collected (using standard analytical procedures) were subjected to ANOVA and significant means separated by Duncan Multiple Range Test. The trial revealed that the meat of SC had outstanding (P>0.05) Fe (22.30mg/kg) and Mn(4.79mg/kg), with no significant variation for DM, while the haemolymph recorded non-significant (P< 0.05) concentration for (Mn, Pb, Co, Ni, Cd and Cr). Its levels of Fe (3.50mg/kg) and Cu (2.06mg/kg) were however significantly (P>0.05) impacted by captive rearing. Generally the level of Cr in the meat and haemolymph were higher than 0.05mg/kg recommendation by WHO, hence snail meat and haemolymph must be consumed with caution and guidance.

Captive Rearing

An experiment was conducted to investigate and compare the impact of treatment, which is the source of snail (wild and captive reared) on the proximate and mineral composition (Na, K, Ca, Mg, P, Fe and Mn) of the meat and haemolymph of African land snails (Archachatina marginata). Ninety (90) adult snails (250.00 + 0.5g) were randomly distributed into two (2) treatments, each of three replicates, (15 snails per replicate), in a Complete Randomized Design. Samples of meat and haemolymph collected using standard procedures were subsequently analyzed for their nutritional qualities, using standard chemical analytical procedures. All data collected were statistically analyzed using ANOVA, while significant variation were separated with Duncan Multiple Range Test of the same package. The proximate composition of the meat revealed higher (P>0.05) DM (26.00%), Ether extract (2.17%) and NFE (3.57%) in SC, while there was a non-significant variation (P<0.05) in most proximate factors for haemolymph, except NFE (4.27%), which was higher (P>0.05) in SW. The mineral profiling of the meat revealed  elevated (PP>0.05) levels of Fee (22.30mg/kg) and Mn (4.79mg/kg) of SC, the haemolymph recorded improved levels (P>0.05) for all mineral elements in SC. In conclusion, the captive rearing of snail had improved impact on thenutritional qualities of SC.

The impact of Cassytha filiformis butanol fraction to the pregnancy and fetal development had been conducted. The fertilized mice were treated withbutanol fraction of C. filiformis at doses of 2.5; 5; 10; and 20 mg/kg of body weight (BW) orally for 5 consecutive days during first, second, and thirdperiods of pregnancy. Parent BW was monitored and the fetal number, BW, death and/or resorptive site and defect were measured. ANOVA followedby Duncan multiple range test (significance at p<0.05) was performed to analyze data. The parent weight was reduced according to fraction doseand the period of pregnancy and the interaction of those factors (p<0.01). Only one mouse treated during the first period became pregnant with lessfetus number (p<0.05) but all of treated during the second and third period but death, resorptive site and underdeveloped fetus were found. Theseindicated the butanol fraction of C. filiformis produced infertility and slowed pregnancy development and produce fetal defect on mice.

African eggplant is an important fruit and leafy vegetable in Africa. Heterosis over mid and better parents was estimated in eight crosses of eggplant involving eight pure lines in a field experiment in 2012 and 2013 cropping seasons. The experiment was laid out using a randomized complete block design with three replications. Collected data was subjected to analysis of variance and significant differences were further subjected to Duncan Multiple Range Test. The aim of this study was to identify superior hybrids that can be advanced in the eggplant breeding program for improved yield and related traits. Significant variation was observed among all traits measured for the parents and hybrids. The highest fruit number was observed in NHS10-40 and in NHS 10-71 x NHS 10-40 among the parents and hybrids respectively. The highest heterosis was recorded in the cross between NHS10-71 x NHS10-40.

Tanaman yang ternaungi mengakibatkan ketersediaan cahaya menjadi berkurang terutama pada intensitas cahaya. Perbedaan karakteristik tanaman yang diatur oleh gennya menyebabkan kemampuan beradaptasi terhadap kondisi ternaungi menjadi berbeda. Tujuan dari penelitian ini adalah mengamati respon tanaman kedelai varietas Ceneng pada kondisi lingkungan dengan intensitas cahaya yang berbeda. Perlakuan pada penelitian ini menggunakan 1 faktor, yaitu naungan. Perlakuan tersebut meliputi perlakuan naungan ± 59% menggunakan pohon pada 0 minggu setelah tanam (MST), naungan paranet pada 8 MST dan tanpa naungan sebagai kontrol. Variabel yang diamati adalah tinggi tanaman, jumlah daun, jumlah cabang, lebar dan panjang daun, waktu berbunga, jumlah bunga, jumlah polong total, jumlah polong hampa dan polong isi, kandungan klorofil serta gula pada daun. Data yang diperoleh dianalisis menggunakan analysis of varians (anova) dengan taraf α = 5%. Hasil uji anova yang signifikan berbeda dilanjutkan dengan uji Duncan Multiple Range Test (DMRT) dengan taraf α = 5%. Hasil penelitian menunjukkan bahwa perlakuan naungan pada tanaman kedelai varietas Ceneng meningkatkan kandungan klorofil a, klorofil b dan karotenoid daun, namun kadar antosianin menjadi menurun. Perlakuan naungan 59% dan 8 MST memberikan rata-rata kandungan gula yang lebih rendah dibandingkan tanpa naungan. Perlakuan naungan pada kedelai varietas Ceneng yang cocok adalah naungan 8 MST.

The City

The impact of the urban effluents of Mytilene (Lesvos island, Greece) on the receiving coastal marine environment, was evaluated by studying the quality of the city effluents (BOD5, COD, SS, heavy metals) and the marine sediments (grain size, organic matter, heavy metals). It was found that the urban effluents of Mytilene contain high organic matter and suspended particle load because of septage discharge into the sewerage network. Furthermore, although the city does not host important industrial activity, its effluents contain appreciable metal load, which is mainly associated with the particulate phase. The city effluents are discharged into the coastal marine environment and their colloidal and particulate matter after flocculation settles to the bottom, where is incorporated into the sediments. Over the years, the accumulation of organic matter and metals into the harbour mud has created a non-point pollution source in the relatively non-polluted coastal marine environment of the island. Copper and Zn were the metals which presented the higher enrichment in the sediments of the inner harbour of Mytilene.

This study aims to investigate the quality and vulnerability of surface water (Aries River catchment) in order to identify the impact of past mining activities. For this purpose, the pollution and water quality indices, Piper and Durov plots, as well vulnerability modeling maps were used. The obtained results indicate that the water samples were contaminated with As, Fe, Mn, Pb and have relatively high concentrations of SO42−, HCO3−, TDS, Ca, K, Mg and high values for the electrical conductivity. Possible sources of the high content of chemicals could be the natural processes or the inputs of the mine drainage. Generally, according to the pollution indices, which were correlated to high concentrations of heavy metals, especially with Pb, Fe and Mn, the water samples were characterized by heavy metals pollution. The water quality index classified the studied water samples into five different classes of quality, namely: unsuitable for drinking, poor, medium, good and excellent quality. Similarly, medium, high and very high vulnerability classes were observed. The Durov and Piper plots classified the waters into Mg-HCO3− and Ca-Cl− types. The past and present mining activities clearly change the water chemistry and alter the quality of the Aries River, with the water requiring specific treatments before use.
