Femi SolajaFollowing the ‘successes’ recorded at the African Athletics Championships in Asaba, strong indications emerged last night that Nigeria intends to bid for the hosting right for the World Athletics Championships to hold in 2025.The President of Athletics Federation of Nigeria (AFN), Ibrahim Gusau at a World press conference held yesterday in Asaba said the country is very much in strong contention to stage the games in 2025 following the gains of the African elite event which would be rounded up tomorrow in Asaba. The quest to stage the global event was fuelled by the decision of International Association of Athletics Federation (IAAF) President, Sebastian Coe to allow an African city to stage the event on the continent and going by the permutations, five countries including Nigeria are in the running to stage the global event.This was the reason why the AFN boss, Gusau, decided to throw Nigeria’s bid into the ring.“With the gains of what we have done here (Asaba 2018), we have all it takes to stage the global event in 2025 and perhaps any other major sporting event on a large scale,” the AFN boss assured last night at the Stephen Keshi stadium in Asaba.Thisday sports reliably gathered at the ongoing championships that other countries that will vie to host the event asides Nigeria are South Africa, Kenya and Morocco. It is however not clear if Asaba will contest or try to edge out Abuja whom the Sports Ministry intends to put forward as the country’s city to bid for the global event.Meanwhile, after four days of intensive competition among the 52 countries that competed for honours at the ongoing African Championships, the CAA Asaba 2018’s flag would be lowered this evening with Nigeria still in touching distance to catch up with South Africa on the overall medals table.As at last night, both countries have 10 gold medals each but the ‘Rainbow Nation’ have more silver and bronze medals to their advantage. More so, Caster Semenya who will be competing in the 800 metres female final looks set to pick the gold just as they hope to win in the 4×400 metres relay final tonight.Share this:FacebookRedditTwitterPrintPinterestEmailWhatsAppSkypeLinkedInTumblrPocketTelegram
Experimental study on the effect of diet on fatty acid and stable isotope profiles of the squid Lolliguncula brevis
Fatty acid and stable isotope analyses have previously been used to investigate foraging patterns of fish, birds, marine mammals and most recently cephalopod species. To evaluate the application of these methods for dietary studies in squid, it is important to understand the degree to which fatty acid and stable isotope signatures of prey species are reflected in the squids’ tissue. Four groups of Lolliguncula brevis were fed on prey species with distinctly different fatty acid and stable isotope profiles over 30 consecutive days. One group of squid were fed fish for fifteen days, followed by crustaceans for a further fifteen days. A second and third group were fed exclusively on fish or crustaceans for thirty days. And a fourth group was fed on a mixture of fish and crustaceans for thirty days. Analysis of squid tissue showed that, after 10 days of feeding, fatty acid profiles of squid tended to reflect those of their prey. Squid that fed on a single prey type, i.e. fish or crustacean, showed only minor modifications in fatty acid proportions after the initial change and fatty acid profiles were clearly distinguishable between the two feeding groups. Shifts in fatty acid proportions towards respective prey profiles could clearly be observed in squid the diet of which was swapped after 15 days. Clear differences could also be seen in fatty acid profiles of squid feeding on a mixed diet with trends towards either fish or crustacean fatty acid signatures. Stable isotope signatures of squid tissues clearly distinguished between animals feeding on different diets and supported findings from fatty acid analysis, thus indicating both methods to be viable tools in feeding studies on squid species.
