We bring you interviews with researchers themselves on freshly published papers covering topics from conservation to evolution. We also discuss the podcast teams' experiences at the University of Exeter. You can access the episode archive from December 2014 onwards, including episodes no longer on Soundcloud, in our google drive: https://drive.google.com ...

(Oct 21, 2021) The pressure to keep billions of humans fed can have a transformative impact on amimal populations. Overharvesting that targets the largest animals can result in reduction of the average size of species, as seen in Caribbean conch snails. And sport-fishing pressure on large mouth bass can winnow out the most agressive in the gene poo…

(Oct 14, 2021) Keratin, the substance wool, hair, and feathers are made from, makes a pretty thin diet, but the clothes moth has been dogging humanity's closets and drawers for hundreds of years, unravelling the work of generations of knitters and weavers to feed its larvae.על ידי Natural Selections

(Oct 7, 2021) Of all the places a cat can hang out, why do do many of them want to hang out in boxes? According to researchers, cats that spend time in close confines are measurably less stressed than those remaining in the open. As Curt Stager tells Martha Foley, it's not just house cats who feel this way.…

(Sep 30, 2021) Martha Foley has never succeeded in keeping a nature journal long-term, but Curt Stager finds them invaluable in his work. He records his observations on paper, but also finds great data through researching the journals of past observers, from Samuel de Champlain to Thomas Jefferson, to ordinary little-known North Country folk.His hi…

(Sep 16, 2021) We tend to think that dogs do this, and that cats do that. We think animal species have a recognizable set of behaviors that define the nature of their kind. But what about individual animals? Does each have something we could understand as a unique personality?על ידי Natural Selections

This week the Natural selection say goodbye.. at least for now. In this our final episode, we touched on some of our favourite topics or subjects that we haven’t discussed in previous episodes. We learned about some extinct species and some species that have reappeared after being thought extinct. We got meta and investigated the world of memes bot…

(Sep 9, 2021) The complex web of species interaction is full of odd associations. Stocking a lake with fish cuts down on dragonflies, which helps pollinators, which helps the flowers bloom. Or it can cut down on amphibians such as newts, which is bad for garter snakes. Invasive flowering purple loosestrife is good for insects and birds that feed on…

(Sep 2, 2021) Martha Foley? - not a fan of bugs. And Curt Stager took a course on them to steady his own reactions. The Natural Selections team looks at the outliers on the spectrum, the largest and smallest of critters with too many legs.New Zealand's weta makes a real handful. The fairy fly is nearly invisible. Some prehistoric dragonflies were b…

(Aug 19, 2021) The ubiquitous bird of cities and towns was designed for a different environment. The pigeon's distinctive style of flight is adapted for maneuverability in tight places - near vertical takeoffs and quick changes of direction. This adaptation to cliff and mountainside environments serves them well among our urban cliff dwellings. Cur…

(Jul 29, 2021) Animals that resemble each other may not be closely related. Sometimes the setting shapes their bodies more than their ancestry. Manatees may look like whales or walruses, but that is only because they adapted to the marine environment in a similar way. Martha Foley and Curt stager talk about convergent evolution.…

This week the Natural Selection found out it's not easy being green.. well not if you’re a mammal anyway. This week we talked all about the colour green and how and why some animals and most plants are green. Why aren’t there any green mammals? How does chlorophyll work? What is that green bird in Hyde park? Listen now to find out more! Next week w…

(Jul 15, 2021) Lake trout require a lot of cold, oxygenated water to survive. Lakes in the Adirondacks of upstate New York are at the southern edge of their natural range. Although about 100 Adirondack lakes and ponds are still home to lake trout, even a small increase in temperature could sharply cut that number.…

This week The Natural Selection got tangled up in the complex world of food webs. From the global ocean food web to the complex biota in a termite's gut, understanding food webs is vital to allow us to recognise the impact we can have on them. In this week's episode, we explored why an ecologist was throwing starfish in the 60s and how wolves broug…
