Important, yet often neglected: Tadpoles play a critical role in the ecology of aquatic habitats. On 279 pages, a new book presents descriptions for 99 species from the southeast Asian island of Borneo, covering all species commonly found, as well as representatives of the more cryptic ones. LIB-scientist Alexander Haas and his team of international collaborators worked over 20 years on its completion and just released “A Guide to the Tadpoles of Borneo”.

Biologists from Hong Kong Baptist University (HKBU) have discovered in Hong Kong waters three new species of hard coral which have never been identified anywhere else in the world. The findings come shortly after their discovery of one new coral and two new nudibranch species, which was announced last year under their research project on coral health in Hong Kong.

An international team of researchers respond to criticisms on previous work that demonstrated Mirror Self-Recognition (MSR) in the cleaner fish Labroides dimidiatus, by 1) successfully repeating the mark test with a larger sample size, 2) showing the MSR behaviour to be the visual result of the mark not a physical response to it, and 3) showing that MSR-trained fish do not show aggression to spatially varied mirror images of themselves. Additionally, they further demonstrate potential self-awareness in L. dimidiatus by showing that they do not demonstrate MSR behaviour when visually presented with the mark on other fish and solidify the importance of ecologically relevant marks presented in previous work by showing MSR behaviour of L. dimidiatus with brown marks, meant to resemble a main food source of the fish, as opposed to no such behaviour in fish with green or blue marks.

Just as humans may leave their home five minutes early to avoid a talkative neighbor or depart work late to avoid a rude coworker, carnivorous mammals may go out of their way to avoid other species. But they’re not trying to navigate awkward social interactions; rather, they are negotiating space and resources for survival.

A collaboration between Osaka City University and Setsunan University sheds light on the effect urbanization has on the flesh fly species Sarcophaga similis. Through a series of laboratory and in-field experiments, scientists show that an increase in nighttime illumination and temperature, two of the major characteristics of urbanization, can postpone S. similis hibernation anywhere from 3 weeks to a month.

Through a series of prosocial choice tasks, researchers reveal prosocial and antisocial characteristics in male convict cichlid fish. The fish distinguish between female breeding partners, unknown females, and rival males by adjusting their actions to either provide food for both them and the females or avoid providing food for the rival males.

A team of scientists in Japan has developed a novel method to induce stem cell generation from the blood samples of dogs. Through this technique, the scientists hope to advance regenerative therapies in veterinary medicine. This would mean that, in the near future, veterinarians might be able to reverse conditions in dogs that were previously thought incurable.

Giants in history

During her short life, Fahire Battalgil (1902 - 1948) achieved renown as the first zoologist from Turkey to make strides in the field of freshwater fish biodiversity.
Lim Boo Liat (21 August 1926 – 11 July 2020), a leading authority in the conservation of Malaysia’s biological diversity, had his initial interest in the outdoors piqued by nature lessons in school. Lim, who helped found the National Zoo of Malaysia and re-establish the Malaysian Nature Society, had a particular interest in researching zoonotic diseases associated with small animals.
Thai physician and conservationist Boonsong Lekagul (1907 – 1992) made major contributions to the preservation of his country’s wildlife.
Ali
Little is known about Ali, a teenager from Sarawak, Malaysia, who was chief assistant to the famous naturalist Alfred Wallace. Most of what is known comes from Wallace’s writings. Ali accompanied Wallace on expeditions throughout the Malay Archipelago from December 1855 to February 1862.
Joo-myung Seok (November 13, 1908 – October 6, 1950) was a Korean butterfly entomologist who made important contributions to the taxonomy of the native butterfly species in Korea.
Võ Quý (1929 – 2017) was a Vietnamese ornithologist who studied the destruction of tropical forests and agricultural lands in Vietnam by Agent Orange, a herbicide used by the U.S. military during the Vietnam War. In addition to planning forest restoration projects, Quý rediscovered the rare eastern sarus crane, an endangered species that had vanished during the war.
