Bird and mammal diversity is declining with biological invasions
The introduction of invasive species leads to a decline in certain native species. A team of researchers from the CNRS and the University of Paris-Saclay has managed to show that 11% of the global phylogenetic diversity of birds and mammals, in other.....»»
Research team resolves decades-long problem in microscopy
When viewing biological samples with a microscope, the light beam is disturbed if the lens of the objective is in a different medium than the sample. For example, when looking at a watery sample with a lens surrounded by air, the light rays bend more.....»»
Mapping plant functional diversity from space: Ecosystem monitoring with novel field-satellite integration
An international team of researchers, led by Professor Jin Wu from the School of Biological Sciences at The University of Hong Kong (HKU), has made a promising advancement in mapping plant functional traits from space using time-series satellite data.....»»
Effects of organic matter input and temperature change on soil aggregate-associated respiration and microbial carbon use
The Qinghai-Tibet Plateau is one of the most dramatically affected regions by global warming. For a long time, the region has been exposed by low temperature and soil moisture, which led to the severe inhibition of the soil biological activities and.....»»
Polystyrene microplastics shown to enhance invasion of exotic submerged macrophytes
Submerged macrophyte invasions and microplastic pollution are major challenges in the context of global change and pose a serious threat to aquatic environments. The presence of microplastics in aquatic ecosystems alters plant function, sediment micr.....»»
The effects of climate variability on children"s migration and childcare practices in sub-Saharan Africa
Shifting weather caused by climate change, especially drought and heat, is linked to a rise in the number of children being raised outside of their biological parents' households in sub-Saharan Africa, according to a study led by researchers at Penn.....»»
Bird flu in cattle: What are the concerns surrounding the newly emerging bovine H5N1 influenza virus?
The confirmed presence of bird flu in American dairy cattle in a March 25 report from the U.S. Department of Agriculture (USDA)—and a case in Texas where a human working with cattle was infected—has put Canadian public health experts on high aler.....»»
Team finds direct evidence of "itinerant breeding" in East Coast shorebird species
Migration and reproduction are two of the most demanding events in a bird's annual cycle, so much so that the vast majority of migratory birds separate the two tasks into different times of the year......»»
Rewilding amphibians: Protecting endangered species to restore ecosystems
In a recent paper published in Biological Conservation, iDiv researchers suggest that given amphibians' ability to act as "canaries in the coal mine" for aquatic environments, they should be reintroduced or rewilded. Rewilding would not only help pro.....»»
Researchers find babbling by zebra finch chicks is important step to memorizing songs
When babies learn to talk or birds learn to sing, the same principle applies: listen and then imitate. This is how the first babble becomes the first word or vocalization. Male zebra finch chicks initially memorize the song of an adult bird. Later, t.....»»
Diverse native wildflower plantings for pollinators in farmlands
Pollinators are declining rapidly, largely due to land conversion and intensification of agriculture. To mitigate their crisis, low-disturbance habitats, such as sown wildflower plantings (commonly known forms are wildflower strips at the edges of ar.....»»
Cut light pollution and treat glass to help migrating birds, say researchers
Spring bird migration has begun. Under cover of darkness, 2.5–3.5 billion birds will fly northward to their breeding grounds in the United States and Canada. According to the Cornell Lab of Ornithology, now is one of the most important times of yea.....»»
Scientists explore the genetic foundations of Rhododendron flower color diversity
A research team has made strides in uncovering the genetic foundations of flower color variation within the Rhododendron genus. The team's review summarizes recent advancements in phylogenetic reconstruction, genome sequencing of various Rhododendron.....»»
How phytochemical diversity affects plant adaptation to stress
Phytochemical diversity plays a critical role in determining plant adaptation and fitness, as well as ecosystem functions and services. However, phytochemicals and their ecological adaptations have long been ignored. Fine (or absorptive) roots, micro.....»»
Report finds significant gender and racial inequities in the educational measurement profession
Gender and racially based employment disparities, differences in perceptions of diversity, equity, and inclusion (DEI), and workplace discrimination remain significant issues in the field of educational measurement, according to a new report......»»
First insights into the genetic bottleneck characterizing early sheep husbandry in the Neolithic period
Modern Eurasian sheep predominantly belong to only two so-called genetic matrilineages inherited through the ewes, so previous research has assumed that genetic diversity must already have decreased rapidly in the early stages of domestication of wil.....»»
Heat and desiccation tolerances predict bee abundance under climate change
Recent research by the University of New Mexico alumnus Melanie Kazenel and colleagues predicts climate change will reshape bee communities in the southwest United States, with some thriving and others declining. The research, titled "Heat and desicc.....»»
Saturday Citations: Listening to bird dreams, securing qubits, imagining impossible billiards
It's Saturday, which means that in a universe where the arrow of time moves backward, people have to go to work tomorrow. In such a hypothetical universe, Garfield hates Fridays—tough to imagine. This week, we looked at several hundred breaking sci.....»»
Microbial food as a food production strategy of the future
The global food crisis is increasing due to rapid population growth and declining food productivity from climate change. Moreover, today's food production and supply system emits a huge amount of carbon dioxide, reaching 30% of the total amount emitt.....»»
Bird Flu Is Spreading in Alarming New Ways
H5N1 has infected cattle across the US and jumped from a mammal to a human for the first time. Experts fear it may someday evolve to spread among humans......»»
What do bird dreams sound like?
For more than 20 years, researchers have known that areas of birds' brains dedicated to singing show neural patterns during sleep akin to the ones they use while awake and singing......»»
