How a butterfly tree becomes a web
Evolution is often portrayed as a tree, with new species branching off from existing lineages, never again to meet. The truth however is often much messier. In the case of adaptive radiation, in which species diversify rapidly to fill different ecolo.....»»
Climate change is moving tree populations away from the soil fungi that sustain them
As our planet warms, many species are shifting to different locations as their historical habitats become inhospitable. Trees are no exception—many species' normal ranges are no longer conducive to their health, but their shift to new areas that co.....»»

Historical signs in the landscape: Investigating the practice of pollarding in Western Norway
In the lush landscapes of Western Norway, pollarded trees bridge the past with modern environmental concerns. In a recent study, researchers investigated what motivates farmers to continue this ancient tree pruning practice......»»
Study details strategies for successful urban tree planting initiatives
Collaborative research led by the University of Massachusetts Amherst outlines five essential themes to promote equitable and sustainable urban tree planting initiatives (TPIs), which is especially timely given the $1.5 billion for urban and communit.....»»
New research into the secrets of the forest: Finnish tree population is made up of families and neighborhoods
The trees in the forest are not just a random group. Fascinating facts reveal pine tree family relationships. The pollen that floats in the air can spread for hundreds of kilometers, but the offspring are usually found in the neighborhood......»»
How do birds communicate? Network science models are opening up new possibilities for experts
Nature lovers will know the scene well. A flurry of birdsong, a shake of a tree and out pops a flock of birds flying away in unison together......»»
Study finds widespread "cell cannibalism" and related phenomena across tree of life
In a new review paper, Carlo Maley and Arizona State University colleagues describe cell-in-cell phenomena in which one cell engulfs and sometimes consumes another. The study shows that cases of this behavior, including cell cannibalism, are widespre.....»»
Genetic drift, not natural selection, identified as main factor driving speciation in endangered pupfish species
Scientists have identified a new member on the genetic family tree of an endangered pupfish native to south-central New Mexico......»»
Actin research shows how butterfly wings get their vibrant colors
The secret of how butterfly wings get their vibrant colors has been revealed in a new study. Using cutting-edge super resolution microscopy, researchers from the University of Sheffield and the Central Laser Facility have been able to investigate the.....»»
Summer 2023 was northern hemisphere"s hottest for 2,000 years, tree rings show
The summer of 2023 was the warmest in the non-tropical areas of the northern hemisphere for 2,000 years, a new study has shown......»»
Meet the new insect killing Utah"s fir trees: Research models impact of the balsam woolly adelgid
A nonnative tree-killing insect is invading northern Utah, attacking subalpine fir and potentially triggering yet another die-off of the region's long-stressed conifer forests......»»
2023 temperatures were warmest we’ve seen for at least 2,000 years
Northern Hemisphere temperatures well beyond natural variability seen in tree rings. Enlarge / Top: a look through the past 2,000 years of summertime temperatures, showing that 2023 is considerably warmer than anything earlier......»»
Want to be an influencer? Our research shows what you need to know first
You're hard at work, lying in a hammock, composing the perfect selfie on the beach. The turquoise sea sets off the idyllic sunset, and just visible though the fronds of a palm tree is the logo of the hotel which is paying you to promote it to your mi.....»»
Evolutionary history shapes variation of wood density: Study
Ecology and evolutionary biology suggest that closely related species are more likely to exhibit morphological and functional similarities compared to distantly related species. Each tree species represents a unique genetic reservoir and is a product.....»»
Loss and hope: US park rangers" climate crisis fight
American biologist Laura Brennan describes the coin-sized Karner blue butterfly as "very delicate and graceful" with a "lovely blue" coloring and "just a little speckling of orange.".....»»
Model predicts future spread of box tree moth in North America
CABI scientists have led research with collaborations from the University of Toronto and University of Guelph, both in Canada, to update a model which predicts the future spread of the box tree moth (Cydalima perspectalis) in North America......»»
Male or female? Scientists discover the genetic mechanism that determines sex development in butterflies
Scientists of the Biology Centre, Czech Academy of Sciences, in collaboration with University of Liverpool have found the genetic mechanism that determines whether individuals of the butterfly species Bicyclus anynana become male or female......»»
Reforestation study finds only a few tree species can survive a century of rapid climate change
Europe's forests have already been severely affected by climate change. Thousands of hectares of trees have already died due to drought and bark beetles. Scientists from the University of Vienna and the Technical University of Munich TUM have now inv.....»»
Researchers discover mechanism regulating bud dormancy release in tree peony
In perennial woody plants, bud endodormancy is crucial for survival under adverse environmental conditions in winter, such as low temperature (LT) and dehydration stress. To break bud dormancy is essential for the resumption of bud growth and floweri.....»»
Scientists map soil RNA to fungal genomes to understand forest ecosystems
If a tree falls in the forest—whether or not anyone registers the sound—one thing is for sure: there are lots of fungi around. Within a forest's soil, hundreds of species decompose debris, mobilize nutrients from that decay, and deliver those nut.....»»
