Cape Town’s caracals expose a hidden rat poison problem for the city’s wildlife

A study found anticoagulant rat poisons in 78% of tested caracals, highlighting a hidden problem for the city's wildlife. Researchers call for tighter control over the sale, distribution, and use of these poisons, which can accumulate in animals' bodies and harm non-target predators.

Dying radio galaxies reveal a shorter, more dynamic afterlife of black hole jets

Astronomers have discovered a new population of faint, rapidly fading remnant radio galaxies, revealing a shorter, more dynamic afterlife of black hole jets. The study found that these remnants are relatively young, with ages ranging from 8-42 million years, and span a wide range of evolutionary stages.

Tiny raptor, tiny range: GPS tracking reveals Pygmy Falcons use less than 1 km² to raise nestlings

A new study found that Pygmy Falcons require less than 1 km² to raise their young, contrary to long-held assumptions. The birds operate within a small breeding home range and coexist with Sociable Weavers in communal nests. This research provides a crucial baseline for understanding the spatial requirements of small raptors.

Long-term road surveys reveal widespread declines in South African birds of prey

A comprehensive study reveals substantial declines in many South African raptor and large terrestrial bird species over the past 16 years. Researchers detected sharp declines in threatened and iconic raptors, including the Endangered Secretarybird, highlighting the vulnerability of species dependent on multiple regions.

Tiny Titans of Recovery - Ancient traces reveal minute fossil life in South Africa’s Cederberg mountains

A team of scientists uncovered fossil evidence of a tiny ecosystem that helped revive marine life after the end-Ordovician ice age and mass extinction event. The discovery provides insights into ancient biological processes and highlights the importance of seafloor ecosystems in regulating carbon and nutrient cycles.
