Monarch butterflies need help, and a little bit of milkweed goes a long way      (via sciencedaily.com)     Original source 

Researchers and community scientists monitored urban milkweed plants for butterfly eggs to learn what makes these city gardens more hospitable to monarchs. They found that even tiny city gardens attracted monarchs and became a home to caterpillars.

From genes to jeans: New genetic insights may lead to drought resilient cotton      (via sciencedaily.com)     Original source 

Cotton is woven into the very fabric of our lives, from soft T-shirts to comfortable jeans and cozy bedsheets. It's the world's leading renewable textile fiber and the backbone of a global industry worth billions. As climate change intensifies, cotton farmers face increasing challenges from drought and heat. However, new research offers hope for developing more resilient varieties that can maintain high yields even under water-stressed conditions.

Climate is most important factor in where mammals choose to live, study finds      (via sciencedaily.com)     Original source 

Using data from 6,645 camera traps across the United States, researchers mapped populations of 25 mammal species. They determined that climate, not human activity, was the primary factor in mammals deciding where to live.

A window of opportunity for climate change and biodiversity      (via sciencedaily.com)     Original source 

World leaders must take advantage of a pivotal window of opportunity for forging a much-needed joined-up approach to tackle climate change and biodiversity loss, say scientists. Without this, work on tackling either crisis could inadvertently harm progress on the other.

Tropical plant species are as threatened by climate change as widely feared, study confirms      (via sciencedaily.com)     Original source 

Biologists who set out to better understand the effects of climate change on plant species in tropical mountain regions found that even small variations in temperature and moisture can have massive impacts, threatening not only plants that live there, but also the ecosystems they support. A study based on labor-intensive fieldwork and analysis in tropical mountain regions shows that a warmer and drier climate will lead to massive losses of plant species.

Groundcherry gets genetic upgrades: Turning a garden curiosity into an agricultural powerhouse      (via sciencedaily.com)     Original source 

Imagine a small fruit that tastes like a cross between a tomato and a pineapple, wrapped in its own natural paper lantern. That's the groundcherry (Physalis grisea) -- a little-known relative of tomatoes that's been quietly growing in gardens and small farms across North America for centuries. Now, this humble fruit is getting a 21st-century upgrade thanks to some cutting-edge genetic research.

Building a roadmap to bioengineer plants that produce their own nitrogen fertilizer      (via sciencedaily.com)     Original source 

Nitrogen fertilizers make it possible to feed the world's growing population, but they are also costly adn harm ecosystems. However, a few plants have evolved the ability to acquire their own nitrogen with the help of bacteria, and a new study helps explain how they did it, not once, but multiple times.

How plant cold specialists can adapt to the environment      (via sciencedaily.com)     Original source 

Evolutionary biologists studied spoonworts to determine what influence genome duplication has on the adaptive potential of plants. The results show that polyploids -- species with more than two sets of chromosomes -- can have an accumulation of structural mutations with signals for a possible local adaptation, enabling them to occupy ecological niches time and time again.

Wolves' return has had only small impact on deer populations in NE Washington      (via sciencedaily.com)     Original source 

Wolves returned to Washington state in 2008. A new study shows that, despite their rising numbers, wolves are not having much of an impact on white-tailed deer, one of their primary prey. Scientists report that the biggest factor shaping white-tailed deer populations in northeast Washington is the quality of habitat available, which is largely determined by human activity. Cougars were second in their impact. Wolves were a distant third.

Tackling the challenge of coca plant ID: Wild vs cultivated for cocaine      (via sciencedaily.com)     Original source 

A new paper reveals that it's not as straightforward as it might seem. Despite decades of data collection by the United Nations Office on Drugs and Crime (UNODC), which has been valuable to monitor changes in areas occupied by illegal coca plantations in South America, there is no reliable scientific method to distinguish between different types of coca plants.
