Ecology: Endangered Species

The key to why plants flower early in a warming world      (via sciencedaily.com)     Original source 

Scientists have unveiled a new mechanism that plants use to sense temperature. This finding could lead to solutions to counteract some of the deleterious changes in plant growth, flowering and seed production due to climate change.

Roots are capable of measuring heat on their own      (via sciencedaily.com)     Original source 

Plant roots have their own thermometer to measure the temperature of the soil around them and they adjust their growth accordingly. Through extensive experiments, a team was able to demonstrate that roots have their own temperature sensing and response system. In a new study, the scientists also provide a new explanation for how roots themselves detect and react to higher temperatures. The results could help develop new approaches for plant breeding.

Conservation in Indonesia is at risk, a team of researchers who study the region argues      (via sciencedaily.com)     Original source 

Indonesia, home to the largest tropical rainforest in Southeast Asia and over 17,500 islands, is a country packed with biodiversity and endangered species. However, scientists studying the region's species and ecosystems are getting banned from Indonesia, and conservation plans are being blocked. A team of conservation researchers with long-term experience in Indonesia discuss scientific suppression and other research challenges they have witnessed while working in the region. They offer suggestions for how to promote nature conservation, protect data transparency, and share research with the public in this and other regions of the world.

Madagascar hippos were forest dwellers      (via sciencedaily.com)     Original source 

Extinct dwarf hippos that once roamed Madagascar lived in forests rather than open grasslands preferred by common hippos on mainland Africa. The findings suggest grasslands that now cover much of the enormous island off the eastern coast of southern Africa were a relatively recent change facilitated by people rather than a natural habitat sustained in part by these famously large vegetarians.

Queensland native forestry can help achieve global environment goals      (via sciencedaily.com)     Original source 

Research has revealed that Queensland native forestry, including timber harvesting, could actually help conserve biodiversity and mitigate climate risks.

Why there are no kangaroos in Bali (and no tigers in Australia)      (via sciencedaily.com)     Original source 

Researchers are using a new model to clarify why millions of years ago more animal species from Asia made the leap to the Australian continent than vice versa. The climate in which the species evolved played an important role.

World's most threatened seabirds visit remote plastic pollution hotspots      (via sciencedaily.com)     Original source 

Analysis of global tracking data for 77 species of petrel has revealed that a quarter of all plastics potentially encountered in their search for food are in remote international waters -- requiring international collaboration to address.

Amazon dolphins at risk from fishing, dams and dredging      (via sciencedaily.com)     Original source 

Amazon river dolphins are under threat from fishing and proposed new dams and dredging, research shows.

Estimating the long-term effects of whale shark feeding practices      (via sciencedaily.com)     Original source 

Increasing opportunities for up-close encounters with sharks and other animals are making wildlife tourism one of the fastest growing tourism sectors -- leading ecology experts to venture to one of the world's main sites to investigate the effects of tourism on endangered whale sharks. At Oslob in the Philippines, Flinders University's Southern Shark Ecology Group and Global Ecology Lab joined local Filipino researchers to measure how the daily feeding regimes for resident whale shark population might have affected their behaviour and physiology by assessing their activity and metabolic requirements.

Mountains vulnerable to extreme rain from climate change      (via sciencedaily.com)     Original source 

A new study finds that as rising global temperatures shift snow to rain, mountains across the Northern Hemisphere will be hotspots for extreme rainfall events that could trigger floods and landslides -- potentially impacting a quarter of the world's population.

European bird communities move to cooler areas, but mountain ranges and coastlines 'control the traffic'      (via sciencedaily.com)     Original source 

A recent study shows that European bird communities have shifted northeastward in the past 30 years. These shifts are faced with obstacles such as mountain ranges and coastlines. Overall, bird communities are moving towards cooler areas but not fast enough to keep up with increasing temperatures.

Freely available risk model for hurricanes, tropical cyclones      (via sciencedaily.com)     Original source 

As human-driven climate change amplifies natural disasters, hurricanes and typhoons stand to increase in intensity. Until now, there existed very few freely available computer models designed to estimate the economic costs of such events, but a team of researchers has recently announced the completion of an open-source model that stands to help countries with high tropical cyclone risks better calculate just how much those storms will impact their people and their economies.

Humans' ancestors survived the asteroid impact that killed the dinosaurs      (via sciencedaily.com)     Original source 

A Cretaceous origin for placental mammals, the group that includes humans, dogs and bats, has been revealed by in-depth analysis of the fossil record, showing they co-existed with dinosaurs for a short time before the dinosaurs went extinct.

New research finds that more than 90% of global aquaculture faces substantial risk from environmental change      (via sciencedaily.com)     Original source 

Many of the world's largest aquatic food producers are highly vulnerable to human-induced environmental change, with some of the highest-risk countries in Asia, Latin America and Africa demonstrating the lowest capacity for adaptation, a landmark study has shown.

Research in a place where geological processes happen before your eyes      (via sciencedaily.com)     Original source 

Taiwan experiences some of the world's fastest rates of mountain building -- they are growing at a faster rate than our fingernails grow in a year. The mountains also see frequent and significant earthquakes, the region experiences about four typhoons per year on average, and in some places, it receives upwards of several meters of rain annually.

Scientists have set out principles for how computational science -- which powers discoveries from unveiling the mysteries of the universe to developing treatments to fight cancer to improving our understanding of the human genome, but can have a substantial carbon footprint -- can be made more environmentally sustainable.

Study of Earth's stratosphere reduces uncertainty in future climate change      (via sciencedaily.com)     Original source 

New research reduces uncertainty in future climate change linked to the stratosphere, with important implications for life on Earth. A significant source of uncertainty relates to future changes to water vapor in the stratosphere, an extremely dry region of the atmosphere 15--50 km above the Earth's surface. Future increases in water vapor here risk amplifying climate change and slowing down the recovery of the ozone layer, which protects life on Earth from harmful solar ultraviolet radiation.
