In the news today...
Choosy males and aggressive females - a role reversal has been found in the sexual behavior of the topi antelope.
Some males are so forcefully pursued by pushy females that they refuse the advances of previous partners.
--- Has anyone experienced this?..lol..
According to research published in the journal Current Biology, this helps males conserve their sperm for the possibility of mating with new females.
---hmm, thank goodness we don’t have to conserve our sperms…else, I’m sure some of us would have run out of stock a long long time ago……lol…”na mate as you go”….just kidding…HIV dey there o..
It therefore increases the chances of fatherhood with the widest possible number of partners.
Dr Jakob Bro-Jorgensen, the scientist conducting the Zoological Society of London (ZSL) research, said: "In cases where the male antelope was free to choose between females, he deliberately went for the most novel mate, rather than the most high-ranking."
--- Hmm, "novel mate" ehn…does that mean the mate that’s most imaginative and can think of novel positions and styles or what….hmmm...just wondering ..I’m kinda confused here..lol
He added: "However, some pushy females were so aggressive in their pursuit of the male that he actually had physically to attack them to rebuff their advances."
--- Lol..I guess this happens…..why these kain tins no dey happen to me nah, I swear I will not physically attack anyone...lol….I no mean say make antelopes pursue me o…lol
The research was undertaken in the Masai Mara area of Kenya, in the traditional breeding grounds of the topi.
Females are fertile for a single day only. The topi antelope (Damaliscus lunatus jimela) come together once a year, for just over a month to mate.
Dr Bro-Jorgensen said: "It is not uncommon to see males collapsing with exhaustion as the demands of the females get too much for them."
-- Lmao, he probably needs some Viagra abi na burantashi…lol….wetin u want make I talk nah…man wey do finish, come collapse, na die be dat nah..lol.
He observed that each female would mate, on average, with four males, while some reached 12 different partners. And each individual would be mated with approximately 11 times, although one pair was observed together on 36 occasions.
-- 36 !!..geez..wtf…even 11 sef…I need to know the exact pills they take for that…lol…its not for me, its for the market…lol..no, I don’t need such to achieve that feat…and yes, you all should take a cue from these antelopes..lol
"[The females must] ensure that they become pregnant, and preferably with a hotshot male, so they must focus all their energies on ensuring that males mate with them in that time," Dr Bro-Jorgensen explained.
These findings are contrary to conventional sexual selection theory which says males are competitive and females are choosy.
Talking to the BBC News website, Dr Bro-Jorgensen said: "We may not have our eyes open to the fact that opposite sexual conflicts may occur more commonly than we think. Normally, males are persistent and females resistant. What I saw in African topi was unexpected."
-- lol, so the males have now become choosy…times are certainly changing….hotshot male ehn, hmmm….now I see the rush for Brad Pitt, Denzel Washington, etc....lol…Wait a sec, did I forget to include my self on that list....I be hot shot nah..
The synchronized mating activity, and the species' promiscuity, makes males the limited resource and females the competitive ones.
It is thought the females are interested in mating with several partners to ensure fertilization, in case their first choice happens to have reduced sperm supply, or is genetically incompatible with them.
-- Synchronized mating ehn…see big grammar…lol..e be like say e don become lottery, try ya luck..lol….Abeg, anybody sabi as dem dey do “synchronized mating”?..Make I add am to the small one wey I sabi..

Quote of the day from BBC: New Emerging order
"Sperm competition is an evolutionary arms race, with males developing increasingly sophisticated strategies to tip the balance towards successful conception and at the same time hinder the chances of rival males."
My prediction: Very soon, a country’s wealth would be measured by the size of its sperm reserves..lol….I wonder which countries and continents would be super powers then?..hmm..let me go think about that, the time is near…lol
Ummh..I think I'm going crazy....lol..peace out folks !!
