The invisible half of biodiversity — How male-biased collections skew research and species conservation

We will probably never find out what the females of Schomburgk’s deer (Rucervus schomburgki) looked like. In historical drawings, travel reports, and museum collections, only remains of males are found—with their unique, many-branched antlers. Females likely carried none, and apparently collectors in the 19th century considered them too inconspicuous to

Lipochromis (Haplochromis) microdon Wiederentdeckung
Haplochromis microdon, an endemic cichlid from Lake Victoria, was considered lost for decades. The species can reach a length of up to 14.8 cm and is one of the specialized fish fry predators in the lake's ecosystem. (© Dr. Anna Mahulu, Institute of Ecology and Evolution, University of Bern)

Lost in Lake Victoria: Cichlid Haplochromis microdon rediscovered after 40 years

For decades, it was considered lost—perhaps even extinct. But now there is new hope for Haplochromis microdon, an endemic cichlid species from Lake Victoria: As reported by the organization SHOAL in an article by Anna Mahulu, the species was detected for the first time since 1985 during targeted research expeditions

Jagd auf Moas

In the Footsteps of Moas: Where New Zealand’s Flightless Birds Find Refuge

The settlement of the Pacific Islands by humans led to rapid waves of extinction for many animal species, whose dynamics are difficult to reconstruct. Among the affected species were the wingless moas, which were only found in New Zealand. These often massive birds went extinct in the 14th or 15th

Buschmoa-Genom rekonstruiert (Anomaloptery didiformis)
The bush moa is the smallest moa species known to date. It was only slightly larger than today’s turkeys and weighed around 30 kilograms. The flightless bird went extinct about 500 to 600 years ago with the settlement of New Zealand. (© Auckland Museum, CC BY 4.0, via Wikimedia Commons)

Deciphered Bush Moa genome provides insights into New Zealand’s extinct avian world

A team of evolutionary biologists has reconstructed the nearly complete genome of the bush moa (Anomalopteryx didiformis), a flightless bird from New Zealand that went extinct 500 to 600 years ago. Researchers from Harvard University, East Carolina University, Osaka University, and the University of Toronto sequenced ancient DNA from a

Neue Käferart: Semanopterus kingstoni
The newly discovered scarab beetle species Semanopterus kingstoni was named after entomologist Tim Kingston, who had collected the only known specimen in 1979. (© Reid, Chris & TEES, NATALIE. (2023). A new, but possibly extinct, species of Semanopterus Hope, 1847 from Lord Howe Island, in the southwestern Pacific Ocean (Coleoptera: Scarabaeidae: Dynastinae). Zootaxa. 5306. 563-570. 10.11646/zootaxa.5306.5.4.)

New beetle species with unique trait discovered on island

Australian researchers recently discovered a previously unknown species of scarab beetle (Scarabaeidae) in the insect collection of the Australian Museum in Sydney. The specimen in question, a female, was collected on January 30, 1979 on Lord Howe, a small island of only 14 square kilometers in the southwest Pacific. The
