New Zealand’s heaviest insect recovers after 11,000 releases

The wētāpunga, the world’s heaviest insect, has recovered from near-extinction in New Zealand following a 15-year breeding program that released over 11,000 individuals into the wild. Conservationists at Butterfly Creek and Auckland Zoo developed specialized feeding techniques to raise nymphs, leading to self-sustaining populations on predator-free islands. The species’ status has improved from 'Endangered' to 'Nationally Increasing,' with researchers now applying these methods to other threatened invertebrates.

Chinstrap penguin collapse on Zavodovski Island marks end of world's largest colony

Aerial surveys reveal a 63% decline in chinstrap penguins on Zavodovski Island since 2011, driven by warming oceans and shifting krill populations. The island has lost its status as the world's largest penguin colony to Cape Adare, while macaroni penguins thrive due to dietary flexibility.

Chinstrap penguin collapse on Zavodovski Island signals Antarctic ecosystem shift

A new study reveals that the chinstrap penguin population on Zavodovski Island, once the world’s largest colony, has plummeted by 63% since 2011. Researchers attribute this rapid decline to climate-driven warming, which has displaced their primary food source, Antarctic krill, further south. While macaroni penguins on the same island have increased in number due to their more flexible diets, the loss of chinstraps threatens broader ecosystem stability. The island has likely lost its status as the world’s largest penguin colony to Cape Adare in the Ross Sea.

Tonga eruption creates 195-square-kilometer pumice raft carrying over 100 species to Australia

An August 2019 underwater volcanic eruption near Tonga generated a massive pumice raft covering 195 square kilometers, larger than Aruba. This floating debris field traveled over 3,000 kilometers to reach Australian waters by April 2020, transporting more than 100 species of marine organisms, including corals and barnacles, across the Pacific Ocean.

Genomic 'Jumping Genes' Explain Ant Explosion After Dinosaur Extinction

A new study reveals that transposable elements, or 'jumping genes,' drove the rapid diversification of ants following the Cretaceous-Paleogene extinction event. By analyzing 163 ant species, researchers found that lineages with high levels of these mobile DNA sequences evolved into the most species-rich groups today. This genomic mechanism allowed ants to thrive in the ecological vacuum left by the asteroid impact 66 million years ago, enhancing their chemical communication and social structures.

Australian Stick Insect Revision Reveals Five Species, Not Two

A University of Sydney team reclassified Australian stick insects in the genus Anchiale, identifying five distinct species where only two were previously recognized. The study describes two new species, including one with unique 'lidded' eggs, and corrects a decades-long misidentification. These findings highlight hidden biodiversity in well-studied regions and offer practical benefits for managing insect outbreaks in forestry and agriculture.

UBC Researchers Unveil Two New Sea Spider Species in Salish Sea After Century Gap

University of British Columbia researchers have described two new species of sea spiders in the Salish Sea, marking the first such discovery in the region in nearly a century. The study, published in Organisms Diversity & Evolution, identifies Callipallene pilosuspedes and Tanystylum kiixin among five total species found in shallow waters. These tiny arachnids, which lack abdomens and breathe through their skin, highlight significant gaps in marine biodiversity data and raise concerns about the impact of climate change on undocumented marine invertebrates.

Genetic analysis splits gentoo penguin into four species, revealing hidden Antarctic lineage

A 22-person international team has reclassified the gentoo penguin into four distinct species, including a previously unknown 'cryptic' species in the Indian Ocean. This is the first new penguin species described in over a century. The findings, published in April 2026, highlight urgent conservation needs for sub-Antarctic populations facing climate change.

Chester Zoo Confirms First Wasp Spider Sighting in North West England

Chester Zoo announced the first recorded sighting of a wasp spider in North West England. The large, black-and-yellow arachnid, nicknamed Wendy, was found on the zoo's estate during a biodiversity survey. Conservationists believe this migration from southern England indicates the effects of climate change on UK wildlife, while emphasizing that the spider poses no threat to humans.

2026 Planetary Health Check: Seven of Nine Earth Systems Breach Safe Limits

The 2026 Planetary Health Check, released by the Potsdam Institute for Climate Impact Research, confirms that seven of nine critical Earth systems have breached their safe operating limits. This annual assessment, authored by 60 scientists, indicates that all transgressed boundaries are at record highs, raising the risk of irreversible planetary change. While stratospheric ozone and atmospheric aerosol levels have improved, other factors like ocean acidification, biodiversity loss, and chemical pollution have worsened. The report urges immediate action to reverse these trends within the current decade to prevent large-scale, persistent damage to Earth’s stability.

Australian researchers reveal five distinct stick insect species hidden within two known names

A University of Sydney team has identified two new stick insect species and restored a third to full status in Queensland, revealing that what were thought to be two species are actually five distinct lineages. The discovery, published in Austral Entomology, highlights significant gaps in insect diversity knowledge despite extensive citizen science data.

Earth on the edge: seven planetary boundaries breached, scientists warn

A Planetary Health Check from the Potsdam Institute finds seven of nine planetary boundaries already breached, including climate change, biosphere integrity, land-use change, freshwater change, biogeochemical flows, ocean acidification and novel entities, with only ozone depletion and aerosol loading still relatively within safe bounds; the report stresses that despite the breaches we have knowledge and solutions to reverse course, notably by strengthening natural carbon sinks and pursuing rapid, scalable actions (Earthshots) to return to a safe operating space.

Seven planetary boundaries breached as life-support systems falter

A landmark analysis by about 60 scientists finds seven of the nine planetary boundaries are breached at record highs, including climate change, biosphere integrity, land-use change, freshwater, biogeochemical flows, novel entities, and ocean acidification—the first time ocean acidification is flagged—while ozone depletion and aerosol loading offer only limited improvement. The report warns that risks of large-scale, potentially irreversible changes are rising and urgent action is needed to restore a safe operating space amid accelerating climate impacts and extreme events.

Black Robin Crowned NZ Bird of the Year After Remarkable Recovery

The black robin, once reduced to a single breeding pair and near extinction, has been named New Zealand’s Bird of the Year after a record 105,000 votes. A pioneering conservation program using foster parenting helped its numbers rebound to about 350 adults, all on pest-free Chatham Island reserves, though the species remains threatened and its habitat is nearing capacity, requiring additional pest-free land.
