Aardwolf

Aardwolf

The aardwolf is the smallest member of the Hyaenidae family, as you can see from the map, it is a species with two separated populations, one in East Africa and one in Southern Africa. It is insectivorous, and exclusively nocturnal, and is generally thought of as one of the harder animals to see in the wild. If incredibly lucky, you can see them feeding alongside Aardvarks, and even Pangolins, but this is rare.  They favour open dry plains and savannahs.

Looking at first glance rather similar to a thin striped hyena, but with a black mane running from its neck, down its back, it can raise this during a confrontation. 

As it ages, it can loose its teeth, however, due to the softness of most insects, this is not the death sentence that it is in many wild animals.

They will defend a territory from others, that covers 1-4 square km, during the breeding season, but are solitary the rest of the time. Both sexes mark their territory, and they will maintain as many as 10 dens throughout their territory, giving them a nearby bolt-hole should danger approach.

They are careful not to destroy a nest that they raid, and will remember where they are, so that they can return for another meal a few months later.

They generally have a density of 1 per square km at most (though this is far higher than animals like lions.

While some farmers mistakenly kill them, thinking that they threaten their livestock, their diet of insects is often good for the farm animals. Their hide is worth a little.

Below is a video of this species and below this is a list of any articles that mention this species. When we have more contacts, you will find them below the news section.

Arctic fox

Arctic fox

The Arctic fox is a white fox which lives throughout the Arctic region, and is common throughout the Arctic biome. Other names include white fox, polar fox or snow fox.

It is a similar size to other foxes, although generally more rounded, so as to loose as little weight as possible.

The Arctic fox preys on many small creatures such as lemmings, voles, ringed seal pups, fish, waterfowl, and seabirds. It also eats carrion, berries, seaweed, and insects and other small invertebrates.

Natural predators of the Arctic fox are golden eagles, Arctic wolves, polar bears, wolverines, red foxes, and grizzly bears. Having said this, they are also keen scavengers and seem to get alarmingly close to these animals on relatively regular occasions. in places where they occur, rodents such as lemmings can form a large part of an arctic fox families diet. In areas where their range overlaps with red foxes, they often build bigger dens with more exits, so as to be able to escape. One of the issues with reduced snow cover, is the fact that red foxes can seize range formerly used by Arctic foxes.

During much of the year, there is as much as a 90-100 degree difference between the internal temperature of the fox and the air temperature. When inactive, they will curl up into a ball, tucking in all extremities to preserve heat as much as possible.

Primarily monogamous, a pair of arctic foxes are required in order to raise their cubs. In areas where predation is higher, arctic foxes change their behaviour. Here they are often far more promiscuous, possibly so that there are more adults who think the young is theirs and therefore more help for protection, should one of the true parents get killed.

They are the only fox with fur on their feet, so as to avoid even more heat loss. It appears to have originated out of foxes from the Tibetan Plateau.

There are 4 recognized subspecies (beyond the common one)

 

    • Bering Islands Arctic fox, V. l. beringensis

    • Greenland Arctic fox, V. l. foragoapusis

    • Iceland Arctic fox, V. l. fuliginosus

    • Pribilof Islands Arctic fox, V. l. pribilofensis

Insect protein is often touted as a way to fight climate change – can we use it? perhaps indirectly. Would you eat beef fed on insects?

There are countries on earth where eating insects has been a common practice for millennia. Unfortunately, elsewhere it is seen as disgusting.

This is unfortunate as it is a far environmentally cheaper way of making protein for human consumption. Indeed where as a beef burger such as a big mac cheese burger can have a carbon footprint of between 3.4 and 4.8kg, vastly more than the weight of itself; in fact insect burgers have lower carbon footprints than many of the current possibilities such as airy, gluten and mycoprotein.

However, given the fact that the consumers at least at the moment will not be willing to eat it, how about feeding the cattle with insects. This would be dramatically more efficient than feeding the cattle soy, not least because much of the soy is grown on land that has rainforest removed for this purpose.
