A new study from North Carolina State University finds that common wild bee species decline as urban temperatures increase.
Some flowering crops, such as beans and cotton, carefully manage the amount and sweetness of nectar produced on their flowers and leaves, to recruit colonising ants which deter herbivores. This strategy balances their needs for defence and reproduction.
During her study on fossil insects at China's Capitol Normal University, student Longfeng Li visited the Smithsonian National Museum of Natural History, USA, carrying two unidentified wasp specimens that were exceptionally well-preserved and 100 million years old. Close examination revealed that both were species new to science. Furthermore, one of them was found to belong to a genus of modern wasps. The study is published in the open access Journal of Hymenoptera Research.
Honeybees may not need key brain structures known as mushroom bodies in order to learn complex associations between odors and rewards, according to new research published in PLOS Computational Biology.
The absence of a single dominant bumblebee species from an ecosystem disrupts foraging patterns among a broad range of remaining pollinators in the system -- from other bees to butterflies, beetles and more, field experiments show.
The fossil of an early snake-like animal -- called Lethiscus stocki -- has kept its evolutionary secrets for the last 340-million years. Now, an international team of researchers, led by the University of Calgary, has revealed new insights into the ancient Scottish fossil that dramatically challenge our understanding of the early evolution of tetrapods, or four-limbed animals with backbones.
When both partners benefit from a relationship -- husband and wife or pollinator and flower -- the relationship is known as a mutualism. Sometimes partners do not deliver their side of the bargain while still reaping the rewards. Research done at the Smithsonian in Panama published shows that unless unfaithful partners are severely punished by the other member of the relationship cheaters may become more common.
One of the most common insecticides used in the battle against the Aedes aegypti mosquito has no measurable impact when applied in communities where the mosquito has built up resistance to it, a study led by Emory University finds.
When army ants move out, a new Drexel University study found that, instead of chasing each other away, birds work together to follow the column and hunt the insects that marching ants scare out of hiding.
As concerns over Zika virus have grown since 2015, the US Centers for Disease Control and Prevention has turned to local public health professionals to compile data on distribution of the two primary mosquito species capable of transmitting the virus, Aedes aegypti and Aedes albopictus. Their findings highlight both the potential widespread presence of the mosquitoes as well as gaps in local surveillance capabilities crucial to understanding the threat of Zika and other mosquito-borne diseases.
