Chris..This is what I meant when I was thinking I had to go through management to get a new title/heading added to a thread. I meant a stickied heading rather than a regular one that would slip down the list of contributions..My terminology wasn't correct. Yet another generational thing, I suspect.
Here are three reports I've read which would, normally, take up three separate post headings..I just wondered if within 'Talk Nature' the stickied heading "Nature News" or similar could be acceptable and then when anyone has a snippet of information that wouldn't warrant a new post, so they would, likely, not post about it, they could just add it. At a glance and in one place we could be made aware of what's going on in the world of Nature ? I think it would be a great thread to browse through,too. At the weekends we get a newspaper and I read these snippets and thought it would be great to share them. With the following they were all articles that I read so I then Googled them so a link can be added but gave a short overview because not everyone reads links. They can be time-consuming. The option is there,though. I think the papers must get the information from online reports as there's a time gap between the online and paper report.
So..first off. https://www.scimex.org/newsfeed/aus...ed-from-singing-to-fighting-to-win-the-ladies
Male Humpback whales, during mating season, used to 'sing' to attract females but now, it seems, they are engaging in battle. Scientists think that this maybe due to the dramatic rise in numbers as a result of conservation efforts which, in the South Pacific, has amounted to an eightfold increase . The problem now for the males is not finding a mate by singing but stopping rivals finding the female first. In the old days the singing male had a much better success rate ..twice that of non-singing male but research from 1997-2015 off the coast of Australia found that by 2015 non-singing males were five times more successful in finding a female ...seemingly, through doing battle. My thoughts... in which case the more aggressive males will win and would that in-itself result in more aggressive male Humpbacks through natural selection ?
2. Little Terns Chesil Beach..Dorset: https://www.bbc.co.uk/news/uk-england-dorset-64639325
In 2021 only three chicks survived from 48 breeding pairs but last year more than fifty-five had successfully fledged. They are the second rarest breeding seabird in the UK with fewer than 2000 pairs arriving from Africa in order to nest.. The population on Chesil Beach fell from 100 breeding pairs in 1997 to none in 2009. This lead to the Chesil Little Tern Project overseen by the RSPB. As ground-nesting birds they are very vulnerable to predators. The increase in fledged chicks has been put down to the demise of a local Kestrel which ,they believe, would have been 5 years old by now and the one that has taken its territory has no inclination to eat the Tern chicks.
3. Shark killers.
Port and Starboard are the names of two infamous killer whales (Orcas) that swim off the coast of South Africa. The pair went on a killing spree last week, attacking and killing at least 17 Broadnose Sevengil sharks in a single day (February 24, 2023). The whales ate only the sharks’ livers and left their bodies to wash up on the beach.
