Nature/Nurture?

It’s fun to think about. A brief discussion on nature and nurture, men and herds, fate and freedom. I’d love to hear from you, chime in the comments if you’re willing. I don’t bite.

Both Environment and Genetic Makeup Influence Behavior

Dogs rule the world, from essential worker to best friend and now master of their domain

Dogs began their descent from wolves some 130,000 years ago when an enterprising pack discovered a new source of food and warmth ripe for exploitation. Today, there is little doubt who is in charge in most households, as canines have transitioned from essential workers for hunters and farmers to loveable, furry, spoiled parasites, doted over every day, and we love them for it.

Wasp: Denmark’s most dangerous animal

A regular guest in the Danish summer is the wasp. Most people have tryed to slap it away, but few people probably know that it is Denmark’s most dangerous animal! The wasp is responsible for many deaths, as you can choke if you are stabbed in the mouth or throat. Many people are also allergic to bee stings, which can be fatal.

Deadly Danish animals and plants (maybe not what you think).

The European hornet (Vespa crabro) is the largest eusocialwasp native to Europe. It is also the only true hornet (genus Vespa) found in North America, having been introduced by European settlers in the 1800s. V. crabro is usually regarded as a pest by those humans who come into contact with it. Vespines, such as V. crabro, are known for making intricate paper-like nests out of surrounding plant materials and other fibers. Unlike most other vespines, reproductive suppression involves worker policing instead of queen pheromone control, as was previously thought.

This species stings in response to being stepped on or grabbed, but generally avoids conflict. It is also defensive of its nest and can be aggressive around food sources. Care should be taken when they are found in these circumstances, as they may sting without warning. European hornets are largely carnivorous and hunt large insects such as beetles, wasps, large moths, dragonflies, and mantises. They also feed on fallen fruit and other sources of sugary food. Mutual predation between medium-sized hornets and the Asilidae (robber flies) is often reported.

Stings: case study

Most cases of stings from V. crabro do not require medical attention, but rarely can be serious. A documented case requiring treatment displayed symptoms including tingling at the site of the sting, headaches, and shortness of breath. In the hospital, the victim was found to have a fast, irregular heartbeat with a blood pressure of 111/63. A subsequent EKG demonstrated atrial fibrillation with a rapid ventricular response. V. crabro venom contains neurotransmitters such as dopamineserotonin, and noradrenalineneurotoxin apamin, as well as enzymes phospholipase A and hyaluronidase, the compound histamine, and proteins melittin and bradykinin. These compounds have been shown to cause episodes of tachycardia in smaller animals. The mechanism of the described attack is still undetermined, but the victim was possibly abnormally susceptible to vespine stings. Currently, the two most effective treatments for reactions are electrical cardioversion or propafenone. The victim in this case study was given an oral dose of propafenone (150 mg) and his atrial fibrillation resolved.

“The badger is not afraid of some stings, but just scratches on, helped by its strident fur, which the hornets have difficulty poking through. The snout is more exposed, but perhaps the individual badger simply gets used to the goat’s toxins and becomes more or less immune over time.”

The European badger (Meles meles) is a badger species in the family Mustelidae native to almost all of Europe. It is classified as least concern on the IUCN Red List as it has a wide range and a large stable population size, and is thought to be increasing in some regions. Several subspecies are recognized with the nominate subspecies (M. m. meles) predominating in most of Europe. In Europe, where no other badger species commonly occurs, it is generally just called the “badger“.

“The wasp buzzard has a number of adaptations to its prickly prey. It has scales on the legs and in the head, where they act like a chain mail, and the mucous membranes of the pharynx are particularly thick-skinned (if you can then speak the epithelium of the pharynx for some kind of inner skin). In many places you can read that it has chemical substances in the plumage that should act as a deterrent to the hornets, but I have not found scientific articles on the subject.”

The European honey buzzard (Pernis apivorus), also known as the pern or common pern, is a bird of prey in the family Accipitridae.

“There are a large number of Danish species of birds, which also like to take a wasp in passing. Unlike the wasp buzzard, however, these birds do not actively seek out wasp nests, but take individual individuals when they encounter them. These include blackbirds and starlings.”

While friendly and cute, this whale has secrets.

Found near Ingøya, Norway, it’s believed to have been trained by the Russian navy and was wearing a camera holder.

Though it mostly seemed interested in fish and playing fetch.

5 Introduced And Non Native Species In The UK

Many Brits across the UK are saddened by the lack of large animals across our landscape. Many of our native large animals have gone extinct mainly due to overhunting and habitat loss. Even though many of our large native animals are now gone, we actually have some secret non native species living in the UK. In This video I will be going through some of these species as I will be going through 5 introduced and no native species in the UK.
