Plant-animal interactions have not always evolved to become mutualistic win-win strategies like birds dispersing seeds of palms while feeding on the fruits. Plants can be rather deceptive. They can hijact sensory vulnerabilities of animals. Secondary metabolites such as nicotine, caffeine, codeine can be rather addictive. Plant chemicals can also be used as deterrent. A sub-Saharan desert plant taily weed (Ochradenus baccatus) detonates a mustard bomb in the mouths of seed predators who dare to chew and destroy its seeds. Plant […]

July 12, 2018 at 8:25 pm / Natural history, Short Observations, Video

In this short observation you can see a juvenile copperhead individual taking its first breath filmed by The Copperhead Institute in South Carolina. Copperheads are ovoviviparous, that is babies are born alive. Eggs incubate inside the mother’s body instead of being oviposited like many other reptiles such as turtles. Copperheads mate in the spring. This results upto 18 offspring in late summer or fall. Snakes may seem as asocial however, prior to giving birth female copperheads may gather in certain […]
