After 12 years apart, elephants may recognise the smell of a relative’s poop

Elephants have a reputation for having a long memory. Scientists have now found that elephants seem to recognise the smell of a relative’s poop – dung, manure, faeces, stools, excrement – even after 12 years apart.

New Scientist’s Life magazine (February 2023) reports on the findings of researchers at the University of Wuppertal in Germany who are studying elephant behaviour, especially elephant memory. 

Two mother-daughter pairs were about to reunite after years apart, and the researchers wanted to test their memories of each other. Would the mothers recognise their daughters’ manure, and would the daughters recognise their mothers’ manure?

RESEARCH: War in the Banded Mongoose colony

The Mongoose is a solitary mammal, but not the Banded Mongoose which lives in a colony of about 20 individuals, and up to 55 individuals. The colony lives underground in burrows, called dens.

The Banded Mongoose (Mungos mungo) is a small carnivorous mammal found in central and eastern Africa – and is related to the Meerkat.

Robert Businge, a researcher in the Banded Mongoose Research Project in the Queen Elizabeth National Park in western Uganda (established in 1995), says the colony is extremely violent and warmongering. ‘They are aggressively violent animals that wage war on neighbouring colonies.’ They are also violent towards each other in their own colony. He added, ‘They brutally murder and maim their rivals, and they also expel close relatives from their group, and will kill them if they don’t leave.’

Supersynchrony in Banded Mongoose females

Banded Mongoose females have a unique system of supersynchrony when they have their babies – they all give birth on the same night.

The Banded Mongoose (Mungos mungo) is a small carnivorous mammal found in central and eastern Africa – and one of 25 African species of mongoose. It is related to the Meerkat.

Most mongooses are solitary, but the Banded Mongoose lives in a colony of about 20 individuals, and up to 55 individuals. The colony lives underground in burrows, called dens.

Mottled Bichir

The Mottled Bichir (Polypterus weeksii) is a freshwater fish in the Polypteridae family of ray-finned fish and reedfish. It is also known as the Fat-Headed Bichir.

The Mottled Bichir is an elongated fish with a series of 7-18 dorsal (back) finlets instead of a single dorsal fin. The finlets (small fins) can be raised and flattened. Its light-grey body has thick scales in patterns of dark-grey bands, and a white underbelly. It breathes through spiracles on the top of its head, four pairs of gills, and ventral lungs – the left lung is shorter than the right lung.

Why do female lions hunt instead of male lions?

Why do female lions hunt instead of male lions?

The African Lion (Panthera leo) is a carnivorous – meat eating – mammal. It kills and eats ungulate mammals (animals with hooves), such as zebra, buffalo, giraffe, wildebeest, warthog, gazelle, and impala. 

Lions live in a pride, which is a group of family members consisting of 10-12 females and their male and female children, called cubs, with one to three dominant males. When male cubs grow up, they become solitary until they form their own pride.

How does the Zebra repel insects?

How does the Zebra repel insects?

The Common Zebra (Equus quagga, formerly Equus burchellii) is common in the treeless plains of East Africa and southern Africa. It is an ungulate (a hoofed mammal).

The Common Zebra is like a horse or pony with short legs, and is black and white striped. The stripes continue all the way to its hooves. No two Zebras are alike, because they all have slightly different markings.

Red-Veined Darter

The Red-Veined Darter (Sympetrum fonscolombii) is an insect in the Libelludlidae family of dragonflies. It is also known as the Nomad Darter.

The male Red-Veined Darter has a deep-red abdomen with a red-brown thorax. Its eyes are brown above and blue-green below. Its wings have red veins and the base of its hind-wings (back wings) is yellow. The female is similar, but her abdomen is yellow-brown with two black lines along each side. Her wings have yellow veins. Both the male and female have black legs with some yellow markings.

CREATURE FEATURE: Small Common Blue Butterfly

The Small Common Blue Butterfly (Polyommatus icarus) is an insect in the Lycaenidae family of blue butterflies.

The Small Common Blue male has iridescent blue wings above with a thin, black-brown border and white fringe. The female is brown above with blue flecks, like dust, and orange spots. Both the male and the female have a row of red or orange spots along the edge of the hindwing (back wing).

Which bird can eat a baby Nile Crocodile whole?

Which bird can eat a baby Nile Crocodile whole? 

The Nile Crocodile (Crocodylus niloticus) is a large freshwater reptile native to Africa. On average, it grows to 300-440 centimetres (10-14 feet) long. The female lays eggs and baby crocodiles hatch after about 90 days. A baby Nile Crocodile measures about 30 centimetres (12 inches) long. 

There is a bird that can eat a baby Nile Crocodile whole, head first.

Why is hay in the treetops?

Why is hay in the treetops?

Most of the ‘hay in the treetops’ are found in African countries, south of the Sahara. They are clumps of dry grass hanging from branches. What are they?

The mini clumps and balls of hay are bird nests. 

They are the nests of weaverbirds. Weaverbirds weave grass and leaves, usually dry grass, into small nests on the branches of trees.

RESEARCH: Cheetahs are the fastest land mammal but cheetah cub survival rates are low

Cheetahs are the fastest land mammal but cheetah cub survival rates are low. Why is this?   

Previous studies of cheetah cub survival rates on the Serengeti Plains of Kenya and Tanzania in Africa in 1994, 2000, and 2004, found that it was exceptionally low because of the lion population attacking them. The survival rate was only 4.8% of cubs – that is 5 cubs out of every 100 cubs born survived beyond 14 months of age.

Researchers from the Zoology Department of the University of Oxford in the United Kingdom conducted a similar study on cheetah cub survival rates in 2013 and published the results in the Journal of Zoology. They compared the cheetah cub survival rate in the Kgalagadi (Kalahari) Transfrontier Park on the border of Botswana and South Africa with the Serengeti study.

Why doesn’t the Meerkat get stung when eating scorpions?

Why doesn’t the Meerkat get stung when eating scorpions?  

The Slender-Tailed Meerkat (Suricata suricatta) is a small mammal in the Herpestidae family of meerkats. The Meerkat is a small Mongoose. It lives in the deserts of southern Africa. 

The Meerkat digs for food, such as lizards, snakes, scorpions, spiders, eggs, small mammals, centipedes, and millipedes.

Scorpions live in the deserts of southern Africa too. They have a venomous tail. The Meerkat is immune to (not affected by) the venom of the scorpion. Also, Meerkat parents teach their young to hunt and eat scorpions.

African Whip Spider

The African Whip Spider (Damon variegatus) is an arachnid in the Phrynichidae family. It is not a true spider because it does not produce silk or venom. It is also known as the Giant Tailless Whipscorpion but it is not a scorpion.

The African Whip Spider has a large, flattened abdomen and cephalothorax, with eight legs. It has six ambulatory (walking) legs and two tactile legs that are longer than the others and act like feelers. It also has two pedipalps which are pincer-like appendages that helps to catch and hold its prey. It is mottled dark-grey to black carapace.
