International Effort to Understand Declining Insect Biodiversity in the Tropics

International Effort to Understand Declining Insect Biodiversity in the Tropics

A team of ecologists from The University of Hong Kong (HKU) are leading an international initiative to investigate the decline of insect populations in the world’s tropical forests. Insects, the most abundant and diverse group of animals on Earth, are experiencing alarming declines, prompting this research effort. The team’s work has earned them an invitation…

Ethiopian wolves have a sweet tooth. These flowers are their lollipops

Ethiopian wolves have a sweet tooth. These flowers are their lollipops

Scientists say the wolves, who go from flower to flower, may be the 1st-known large carnivore pollinators Ethiopian wolves like to feast on flower nectar, study finds Ethiopian wolves may be carnivores, but new research suggests they supplement their diet with the sweet, sticky nectar of native flowers. The sleek predators of the Ethiopian highlands have been observed…

What we can learn from how flies set the thermostat

What we can learn from how flies set the thermostat

Tiny, cold-blooded animals like flies depend on their environment to regulate body temperature, making them ideal “canaries in the mine” for gauging the impact of climate change on the behavior and distribution of animal species. Yet, scientists know relatively little about how insects sense and respond to temperature. Using two species of flies from different…

Restoring wildlife habitats in wealthy nations could drive extinctions in species-rich regions

Restoring wildlife habitats in wealthy nations could drive extinctions in species-rich regions

Some efforts to preserve or rewild natural habitats are shifting harmful land use to other parts of the world – and this could drive an even steeper decline in the planet’s species, according to a team of conservation scientists and economists led by the University of Cambridge.    Researchers from over a dozen institutions worldwide have…

Where do invasive species spread and why? Researchers take a novel approach to find the answer

Where do invasive species spread and why? Researchers take a novel approach to find the answer

Science tells us invasive species — like the spotted tilapia — are always on the move, making it difficult for scientists to simulate their spread and predict where they will go next. Researchers at the University of Florida Institute of Food and Agricultural Sciences took a deep dive to understand why certain locations are more…

Fruit flies’ courtship song may hold key to controlling mosquitoes

Fruit flies’ courtship song may hold key to controlling mosquitoes

How fruit flies mate may hold a key to limiting the spread of diseases by mosquitoes. In a new study, University of Iowa researchers found a gene that orchestrates the antenna movements of female fruit flies, which is central for them to detect the unique sound produced by prospective male mates. That gene, the Iowa…

Plant’s name-giving feature found to be new offspring-ensuring method

Plant’s name-giving feature found to be new offspring-ensuring method

130 years after a fungus-eating plant received its name, a Kobe University researcher has uncovered the purpose of the structure that inspired its name — revealing a novel mechanism by which plants ensure reproduction. MAKINO Tomitaro, a towering figure in Japanese botany, named around 1,000 species and discovered about 600 new plants between 1887 and…

Biodiversity at risk in most rainforests

Biodiversity at risk in most rainforests

New research has revealed less than a quarter of the remaining tropical rainforests around the globe can safeguard thousands of threatened species from extinction. The research, co-authored by The University of Queensland’s Professor James Watson, evaluated the global availability of structurally intact, minimally disturbed tropical rainforests for more than 16,000 species of mammals, birds, reptiles,…

Lifesaver for wild bees: the importance of quarries

Lifesaver for wild bees: the importance of quarries

Connectivity and maintenance measures support wild bees in limestone quarries A research team at the University of Göttingen, Germany’s Nature And Biodiversity Conservation Union (NABU) in Rhede, and the Thünen Institute in Braunschweig has investigated the importance of limestone quarries for wild bee conservation. Diverse landscapes with good connectivity between quarries and calcareous grasslands proved…
