Colônias de vespas sem rainha dependem de ajudantes ocultas durante o caos

Quando uma rainha vespa desaparece, sua colônia tropical entra em violentas disputas de poder. Uma nova pesquisa mostra que algumas fêmeas evitam as brigas e, em vez disso, mantêm tarefas essenciais para evitar o colapso.

Pesquisadores da University College London examinaram colônias de vespas tropicais de papel, Polistes canadensis, no Panamá. Eles removeram as rainhas de grupos estabelecidos e observaram uma competição agressiva imediata entre as fêmeas pela dominância. A ordem social normal rapidamente se rompeu à medida que várias vespas disputavam a posição principal.

A hybrid population of honeybees in Southern California demonstrates natural resistance to Varroa mites, a major threat to bee colonies. Researchers at UC Riverside found these bees carry 68% fewer mites and require far less chemical treatment. The discovery, detailed in a new study, suggests early-life defenses in larvae may hold the key.

Buff-tailed bumblebees have demonstrated an ability to recognize rhythmic patterns, surprising scientists who thought it required a large brain. Researchers trained the insects to distinguish sequences of flashing lights and vibrations, akin to Morse code. The findings suggest even small-brained animals can process abstract rhythms.

Scientists observed a rare tropical katydid changing color from bright pink to green over 11 days in Panama. The transformation helps the insect mimic young rainforest leaves that start pink before maturing green. Researchers describe it as a survival strategy rather than a mutation.

Researchers at the University of East Anglia have found that Seychelles warblers with closer social ties share more similar gut microbes, particularly anaerobic types spread through direct contact. The study on Cousin Island suggests social interactions drive this microbial exchange. Similar effects likely occur among humans living together.
