Alien plants and animals threaten Antarctica
While scientists globally have been tracking the impact of introduced, non-indigenous species into environments—this collaborative research between La Trobe University, the Arthur Rylah Institute and Monash University is the first to document alien.....»»

Not too big, not too small: Why modern humans are the ideal size for speed
The fastest animal on land is the cheetah, capable of reaching top speeds of 104 kilometers per hour. In the water, the fastest animals are yellowfin tuna and wahoo, which can reach speeds of 75 and 77 km per hour respectively. In the air, the title.....»»
African Sahara "greening" can alter Northern Hemisphere climate, modeling study finds
Africa's Sahara Desert may be considered a vast expanse of barren sand with limited vegetation, an extreme environment for plants and animals to thrive, but life always finds a way. Indeed, vegetation growth in the desert has waxed and waned over mil.....»»
The reasons flowers wilt could explain how plants spend (and save) their energy
Wilting flowers might not signal poor flower or plant health, but rather the effects of a sophisticated resource management strategy in plants, millions of years in the making......»»
This is what it sounds like when the Earth"s poles flip
Is there something strange and alien confined deep inside the Earth? Is it trying to break free and escape into the heavens? No, of course not......»»
Researchers study effect of phosphorous and irradiance on the invasive plant Chromolaena odorata
Resource competition is an important factor affecting the invasion success of alien plants, and environmental factors influence the competition outcomes between invasive and native plants. Chromolaena odorata has been listed as one of the main invasi.....»»
A comparison of bat and bird wings reveals their evolutionary paths are vastly different
Bats are incredibly diverse animals: They can climb onto other animals to drink their blood, pluck insects from leaves or hover to drink nectar from tropical flowers, all of which require distinctive wing designs......»»
Hubble and Webb probe surprisingly smooth disk around Vega
In the 1997 movie "Contact," adapted from Carl Sagan's 1985 novel, the lead character scientist Ellie Arroway (played by actor Jodi Foster) takes a space-alien-built wormhole ride to the star Vega. She emerges inside a snowstorm of debris encircling.....»»
Nigeria"s last elephants: What must be done to save them?
Nigeria has a unique elephant population, made up of both forest-dwelling (Loxodonta cyclotis) and savanna-dwelling (Loxodonta africana) elephant species. But the animals are facing unprecedented threats to their survival. In about 30 years, Nigeria'.....»»
How researchers can maximize biological insights using animal-tracking devices
Biologgers allow us to see with unprecedented precision how animals move and behave in the wild. But that's only part of the picture, according to a UC Santa Cruz ecologist renowned for using biologging data to tell a deeper story about the lives of.....»»
New Age ritual that send "bad energies" up in smoke may contribute to overharvesting of wild plants
A commercialized New Age ritual is causing not only "unwanted energies" to go up in smoke, but also foreign wild plants. A study by Utrecht University researchers Isabela Pombo Geertsma and Anastasia Stefanaki, alongside colleagues from Wageningen UR.....»»
Algae-jellyfish relationship provides insight on immune health
Marine animals like jellyfish, corals and sea anemones often live with algae inside their cells in a symbiotic relationship. The animals give the algae nutrients and a place to live; in return, algae give the animals some of the food they make from s.....»»
Study finds comb jellies can reverse age
A new article published in Proceedings of the National Academy of Sciences reveals the unprecedented ability for reverse development in a ctenophore, also called comb jelly. The findings suggest that life cycle plasticity in animals might be more com.....»»
Recent whale deaths highlight risks from Antarctica"s booming krill fishery
Two humpback whales were found dead and another seriously injured this year in huge nets used to collect krill for fishmeal and omega-3 pills near Antarctica, The Associated Press has learned......»»
These hornets break down alcohol so fast that they can’t get drunk
"No signs of intoxication or illness, even after chronically consuming huge amounts of alcohol." Many animals, including humans, have developed a taste for alcohol in some form, b.....»»
Soybean domestication linked to higher mesophyll conductance for increased photosynthesis
In a new study conducted by the Realizing Increased Photosynthetic Efficiency (RIPE) project, researchers at the University of Illinois Urbana-Champaign looked back in time at soybean growth and discovered that modern plants have increased mesophyll.....»»
How far south did Polynesian seafarers sail?
Prehistoric Polynesian seafarers were highly skilled and undertook some of the longest and most technically demanding voyages in prehistory—but did they ever sail into very high latitudes with landfall in Antarctica, as some scholars have argued?.....»»
Coral exudates, not algae, linked to bacterial growth that threaten reefs
A study led by the University of Bremen suggests that on algae-dominated coral reefs, it is not the algae but the corals themselves that may contribute to the growth of harmful bacteria. This discovery suggests that a disturbance in the natural compo.....»»
Researchers find Weddell seals avoid extreme dives at midday
Erebus Bay, Antarctica, is home to the southernmost population of the world's southernmost living mammal—the Weddell seal. These seals may look like couch potatoes when they are resting on the ice, but Weddell seals go to great lengths to make a li.....»»
Invasive plants drive homogenization of soil microbial communities across US, new study finds
Invasive plants are doing more than just taking over landscapes—they're also changing the soil beneath them. A new study co-authored by Matthew McCary, assistant professor of biosciences at Rice University, reveals that these species are reshaping.....»»
