Plants are pretty flexible when it comes to chromosome numbers. Continue reading “Is more DNA better?”
Evolution and adaptation to different environments seem like straightforward processes. If you treat bacteria to a low dose of antibiotics, chances are they’re going to evolve resistance. But this process isn’t as simple as it seems: different factors determine whether or not those bacteria will develop resistance. Continue reading “Evolution at the edge”
We’re amassing quite a number of posts about biodiversity and speciation (the process of becoming a new species). Not too surprising, really, because that’s a huge question in ecology and evolution! Continue reading “The way you move…”
We can’t get enough of the intricacies of volatile organic compounds, whether they’re for communication among ants, communication between bacteria and fungi, shedding light on shaded plant leaves, or a means of sexual selection in moths. These volatiles are incredibly versatile, and new research published in the journal Evolution doesn’t disappoint. Continue reading “VOCs are in the air 💕”
Have a look outside. What organisms do you see there? (For me, some squirrels and elm trees!) Now think about all the other kinds of places those animals might live in, with different climates than where you are: somewhere way hotter, or drier, or with less pronounced seasons. What about the animals there? What are they like?Continue reading “Setting the standard”
Noise pollution is becoming (ok, already is) a problem in cities. Traffic, construction, people yelling: you name it, it’s probably noisy. Cities aren’t the only places where humans make noise, though. Even in more rural areas, industrial projects, airports, oilfields, etc. raise quite a racket. Continue reading “Singin’ in the prairie”
Something cool is going on in the nematode worm Auanema rhodensis! Nematodes are tiny (0.1 – 2.5mm) roundworms that are found pretty much everywhere, many species of which are parasitic. The popular research species C. elegans (pictured below) is also a nematode, for reference. Continue reading “Meiosis, modulated”
J.B.S. Haldane once remarked that if there is a creator, they must have an inordinate fondness for beetles. Hundreds of thousands of beetle species have been named; by contrast, there are only about 60,000 described species of vertebrates*. Naturally, the sheer number and diversity of beetles out there is of great interest to biologists.
