I know this sub is about biodiversity but that is the mindblowing thing, the incredible diversity of minerals on earth (and my oh my the diversity is overwhelming) is a consequence of the incredible biodiversity of life, and it is not unlikely that it worked the other way too, a diversity of minerals may have been a formative part of the development of life.

A diversity of minerals/chemical may have facilitated the formation and diversification of life which fed back into the further diversification of minerals...

It suggests a beautiful perspective to understand ecosystems and the essential role of diversity for stability.

Summary

Five Hawaiian crows on Wednesday were released on Maui for the first time as part of an ongoing effort to return the species to its home, conservationists said.

The Hawaiian crows, or alala, were last found on Hawaii’s Big Island, but they went extinct in the wild in 2002, officials with the San Diego Zoo Wildlife Alliance said in a statement. The birds, described as intelligent and charismatic, are the last survivor of all the Hawaiian crow species. Habitat loss, predation and disease by introduced species are threats, among other factors.

• The WAP Complex of protected areas that straddles the border region of Benin, Burkina Faso and Niger is one of West Africa’s most important protected areas and a haven for many iconic endangered species.
• Servals, caracals and African wildcats are also found in the WAP Complex, but almost nothing is known about their status, distribution, ecology or threats.
• Covert surveys of medicine markets in the region have found serval and caracal skins, though it’s not known if the skins originated within the WAP Complex.
• The presence of jihadist militants in the region severely impacts conservation and research, particularly in the Niger and Burkina Faso portions of the complex.

In the border region between Benin, Niger and Burkina Faso lies a network of protected areas that form one of the largest intact wildernesses in West Africa. The W-Arly-Pendjari (WAP) Complex is a mosaic of gallery forests, savannas and riparian habitats, and the last refuge for many of the region’s most iconic species, including West African lions (Panthera leo leo), savanna elephants (Loxodonta africana) and cheetahs (Acinonyx jubatus).

With conservation focused on these threatened and beloved species, it’s easy for the small cats to get lost. There are three species of small cats — servals (Leptailurus serval), caracals (Caracal caracal) and African wildcats (Felis lybica) — in the WAP complex. Though all three have a conservation status of least concern on the IUCN Red List, there are few hard facts about their numbers in the WAP Complex or West Africa. With continuing insecurity plaguing the region, and little money for small cat research, these species risk falling even further into obscurity.

At the heart of the WAP Complex lie three strictly protected areas: Pendjari National Park in Benin, Arly National Park in Burkina Faso, and W Regional Park, which straddles the Benin, Burkina Faso and Niger border region. Together, these parks, along with adjoining hunting zones, wildlife reserves and areas under other forms of protection, cover 34,000 square kilometers (13,100 square miles). The core area, about half of it, is a UNESCO World Heritage Site.

Over the past few years, the region has been plagued by insecurity. Jihadist militants are entrenched in the Burkina Faso and Niger portions of the complex, with violence increasingly spilling over into Benin. Conservation work has become difficult and dangerous, though South Africa-based organization African Parks, which manages Pendjari National Park and the Benin portion of W, still carries out some biomonitoring activities, says Jacques Kougbadi, marketing and communications coordinator for African Parks.

Giant Canada geese, so ubiquitous today in cities across the country, were once considered extinct. What can we learn from watching them up close?

In the opening minutes of Karsten Wall’s short film, Modern Goose, a flock of geese arrives in a cacophony of honks, barks, cackles and splashes, as it touches down in a human-made pond behind an outlet mall. The ruckus blends with the hum of traffic as they waddle under the neon glow of billboards and parking lot lights, picking at patches of grass and dodging vehicles in the drive-thru lane.

It’s a scene that would feel familiar in most Canadian cities, where geese have become ubiquitous to daily life. As it happens, these geese are Winnipeggers, descendants of a historically significant flock once thought to have disappeared altogether.

“A lot of people in the cities consider them pests, but then a lot of people go to Fort Whyte to watch the migration,” he says. “It was important to me to just let people sit and appreciate their amazing flying abilities, their migration abilities and how well they’re actually doing.”

There are other aspects of goose life that are relatable to humans. They mate for life (with just a 15 per cent separation rate, according to a Canadian field naturalist study titled “Divorce in Canada Geese”), raise their young together and migrate as a family. When female geese mature and find mates, they return to the place they were hatched to build nests of their own.

With today’s geese so abundant, it’s difficult to imagine a world without them.

But at the turn of the 20th century, unregulated hunting, egg collection and habitat erosion had nearly wiped out North America’s goose population and the giant Canada goose was thought to have disappeared altogether.

The largest animal on Earth is thought to be the blue whale, but these strange sea creatures can grow even longer — reaching up to 150 feet (46 meters) in length.

There are around 175 species of siphonophores living in the deep sea throughout all of Earth’s oceans, although not every species is found in each ocean. Many siphonophores are long and string-like, but some, like the venomous Portuguese man o'war (Physalia physalis), resemble jellyfish.

Although a siphonophore may look like a single animal, it is actually a colony made up of individual organisms called "zooids," which each have a distinct function within the colony despite being genetically identical. Some catch prey and digest food, while others enable the colony to reproduce or swim. An individual zooid cannot survive on its own because they specialize in one function, so they rely on each other to form a "body."
