Ecology and Social Complexity Shape Primate Same-Sex Behavior

A global synthesis of 491 primate species finds that same-sex sexual behavior (SSB) is widespread and its occurrence is driven by both environmental pressures (drier habitats, food scarcity, predation) and social factors (larger sexual dimorphism, longer lifespans, more complex hierarchies). Structural equation modelling suggests environmental and life-history traits affect SSB mainly indirectly, while social complexity directly promotes it, highlighting SSB as a context-dependent trait shaping primate evolution and sexual diversity.

Tiny, ubiquitous engineers: springtails underpin Earth’s ecosystems

Springtails (Collembola) are tiny, ancient invertebrates found in virtually every habitat on Earth—from Mount Everest to Antarctica and even homes. They use a spring-loaded furcula to leap and a moisture-absorbing collophore to survive desiccation. As key players in regulating bacteria and fungi and in breaking down organic matter, they sustain ecosystems across forests, deserts, caves, and more. Giant springtails living in rotting wood can reach up to 17 mm, and recent work reshapes their classification, revealing a southern-hemisphere split tied to Gondwanan history, while warming and drying climates threaten many populations in Australia and New Zealand—a silent mass extinction for these remarkable yet underappreciated creatures.

AI Advances in Assessing Tourist Effects on Seals

Artificial intelligence is significantly speeding up the process of monitoring seal populations at Newburgh beach in Aberdeenshire, helping researchers assess the impact of tourism on seals by analyzing drone footage more efficiently. This technology allows for better understanding of seasonal seal behavior and human disturbance, aiding conservation efforts.

Scientists Warn of Global Risks from Synthetic 'Mirror' Microbes

Scientists warn that the discovery of a 'second Tree of Life' could have significant ecological and evolutionary implications. This concept suggests the existence of a separate lineage of life forms that evolved independently from known organisms, potentially disrupting current understanding of biodiversity and ecological balance. The findings could lead to a reevaluation of evolutionary theories and necessitate new conservation strategies.

Record-Breaking Humpback Whale Swims 13,000km Across Oceans for Mating

A male humpback whale set a new distance record for the species by traveling 8,106 miles across three oceans, from Colombia to Zanzibar, in search of mating opportunities. This journey, documented through photographs and published in Royal Society Open Science, reveals that humpback whale migrations are more flexible than previously thought, as the whale interacted with multiple populations along the way. The study suggests that the whale's motivation was likely reproductive, influenced by environmental changes and increased competition among males.

Stunning Photo Shows Bird's Hidden Eyelid in Action

Peter Hudson's photograph of a secretary bird closing its third eyelid while catching a locust won the ecology and environmental science category in the 2024 Royal Society Publishing Photography Competition. The image highlights the bird's nictitating membrane, which protects its eyes during feeding. The competition, in collaboration with the Royal Photographic Society, celebrates images revealing hidden scientific phenomena. The overall winner was Angela Albi's aerial photo of sharks hunting in the Maldives.
