Indeed, recently developed procedures of numerical extrapolation of partial samplings now allow to estimate, with fair accuracy, not only the number of the still unrecorded species but, moreover, the distribution of abundances of each of these unrecorded species, thereby making available the full range of the Species Abundance Distribution, despite dealing with incomplete data only. In turn, this allows to address a series of descriptive and functional aspects of the internal organization of species assemblages, which otherwise would have required disposing of truly exhaustive samplings.</p> <p>This approach is applied, here, to the previously reported partial samplings of six neighboring reef-fish communities from Tiran Island, Red Sea, with the goal of better understanding their internal organization in relation to their respective environments.</p> <p>In practice, the numerical completion contributes to avoid erroneous interpretations that would likely stem from considering only the incomplete field data. This point is especially relevant when studying reef-associated communities because accurate understanding of their organization will help guiding and refining at best the protective measures required by these particularly vulnerable communities.</p> Jean Beguinot ##submission.copyrightStatement## 2019-12-30 2019-12-30 1 21 10.9734/ajee/2019/v11i330136 Appraisal of Starch-bonded Briquettes Utilization among User-respondents in Port Harcourt, Rivers State, Nigeria <p>The study appraised briquette users’ opinions on the apparent properties and environment friendliness of the briquettes bonded by 30% and 40% starch composited saw dust collected from Marine and Illoabuchi Sawmills in Port Harcourt, Nigeria. Multistage sampling was used amongst 100 plantain (Bo-lae) roasters, meat barbecue (Suya), Garri (carbohydrate based food), and Akara (baked bean cake) respondents to elicit information on use of briquettes as an alternative source of energy on a 4-point Likert scale. The results showed that male user-respondents were 22 (88%) and 21 (84%) and female 3 (12%) from Marine and Illoabuchi sawmills, respectively. The 41-50 respondent age bracket were the most represented in both sawmills-Marine Base and Illoabuchi 12 (48%) and 11 (44%) respectively, followed by 31-40 (7: 28%) and 51-60 (4: 16%) in Illaboachi sawmill, while the 51-60 and 31-40 age groups were 6 (24%) and 5 (20%), respectively. Amongst the businesses run by respondents, users from Marine Base, plantain roasting was highest at 7 (28%), followed by fish barbecue and akara with 6 (24%), Suya had 5(20%), while at Illoabuchi, Suya grillers had 9 (36%), followed by plantain roasters 8 (32%). Garri stewards and Akara had the same 3 (12%). Environment friendliness and physical properties showed that briquettes smoked well with cut off Mark (M =3.04 and 3.80), smelled pleasantly (M=3.03 and 2.68), stuffy and choky smoke (M=0.4 and 1.00) and irritation of eyes had M=3.25 and 4.00 at Illaobuchi and Marine Base sawmills, respectively. Darkening pots, burning with dark smoke and being affected by water had their cut off marks at 1.33 and 1.40 (rejected), 2.63 and 2.50 (accepted) and 2.01 and 2.12 (rejected), portable, cheap and useful had M= 2.45 and 3.00, 3.60 and 3.60 and 3.40 and 3.09 from both mills respectively. This study recommends that briquetting of sawdust from sawmills be promoted via automation to maximize its utilization status.</p> N.
