The paper published in the current issue of the Journal of Applied Ecology gives farmers of pollination-dependent crops tangible results to convert marginal acreage to fields of wildflowers said Rufus Isaacs MSU entomologist
As part of the study marginal lands surrounding productive blueberry fields were planted with a mix of 15 native perennial wildflowers.
Once the wild bees were more abundant more flowers turned into blueberries and the blueberries had more seeds
Based on the results a two-acre field planted with wildflowers adjacent to a 10-acre field of blueberries boosted yields by 10-20 percent.
which can recoup the money from planting wildflowers. With 420 species of wild bees in Michigan alone it makes sense to attract as many free pollinators as possible.

one month after the experiment had started establishment of seedlings was about five times higher for dispersed than for non-dispersed seeds.
The farther the ants had transported the seeds the higher was the chance that Clusia seedlings had established.
Due to the ecosystem service provided by ants in the degraded areas a faster and sustainable establishment of tree seedlings like Clusia may be expected.
#Dry future climate could reduce orchid bee habitatduring Pleistocene era climate changes neotropical orchid bees that relied on year-round warmth
In previous studies researchers have tracked male and female orchid bees and found that while females stay near their nests male orchid bees travel with one study concluding they roam as far as 7 kilometers per day.
These past findings corroborated by genetic data in the current study reveal that males are more mobile than females.
since male orchid bees habitually travel far they can keep bee populations connected and healthy.
Climate and ecological niche computer model simulations were matched closely by genetic data of the two less-tolerant orchid bee species. The genetic data included mitochondrial markers
Orchid bees live in the neotropics an ecozone that includes part of South and Central america the Mexican lowlands and the Caribbean islands.
They are one of the most important pollinators visiting many types of plants including some 700 species of orchids that are pollinated exclusively by these bees.
In particular the presence of large densities and varieties of flowering plants supports a number of pollinating insects
and northern Asia) and non-Palaearctic garden plants bees simply visited plants in proportion to flower availability. Indeed of the six most commonly visited garden plants only one--Foxglove--was a British native and only three of Palaearctic origin.
Among individual species however there were distinct preferences with the long-tongued'garden bumblebee'(Bombus hortorum) showing a strong preference for'native'Palaearctic-origin garden plants choosing them for 78%of its flower visits.
Dr Hanley added As a general rule bees will go wherever there are flowers available. However if native plants were to disappear completely from our towns
when it flowers but the weather conditions must be just right--warm humid and wet. The wheat flower must be open for the fungus to enter Yen explains.
In susceptible varieties the fungus kills the infected cells in the head thereby plugging the transport of water and nutrients to the upper part of the head.
When inexperienced bees encountered the most complex flower first they were unable to access the syrup reward
Bees allowed to progress through increasingly complex flowers were able to navigate the most difficult ones.
#Reintroduction experiments give new hope for plant on brink of extinctiona critically endangered plant known as marsh sandwort (Arenaria paludicola) is inching back from the brink of extinction thanks to the efforts of a UC
Ingrid Parker the Langenheim professor of plant ecology and evolution at UC Santa cruz got involved in the marsh sandwort recovery effort at the request of the U s. Fish and Wildlife Service (USFWS.
Although it used to occur all along the west coast from San diego to Washington state this wetland plant with delicate white flowers had dwindled to one population in a boggy wetland in San luis Obispo County.
We planted out marsh sandwort in different habitats within a stone's throw of each other
A key finding was the discovery that a relatively common plant can serve as a useful indicator of good habitat for the endangered marsh sandwort.
Field experiments in two California State Parks in Santa cruz County showed that marsh sandwort does well in areas dominated by water parsley.
and light conditions that work well for this endangered species. That isn't to say that every place water parsley grows will be good for marsh sandwort
but producing flowers and seeds in the field was fantastic. Arenaria cuttings root easily making it relatively straightforward to propagate large numbers of plants in the UCSC greenhouses.
With help from other undergraduates in Parker's lab they prepared the plots planted out marsh sandwort cuttings propagated in the UCSC greenhouses

#As hubs for bees, pollinators, flowers may be crucial in disease transmissionlike a kindergarten or a busy airport where cold viruses and other germs circulate freely flowers are common gathering places where pollinators such as bees
and butterflies can pick up fungal bacterial or viral infections that might be as benign as the sniffles
But almost nothing is known regarding how pathogens of pollinators are transmitted at flowers postdoctoral researcher Scott Mcart
As major hubs of plant-animal interactions throughout the world flowers are ideal venues for the transmission of microbes among plants and animals.
Mcart adds Our intent with this paper is to stimulate interest in the fascinating yet poorly understood microbial world of flowers.
We found several generalities in how plant pathogens are transmitted at flowers yet the major take-home from our paper may be in pointing out that this is an important gap in our knowledge.
and where transmission must have occurred at flowers or pathogen-induced pseudoflowers. These are flower-like structures made by a pathogen that can look
and smell like a real flower for example. Regarding animal pathogens they identified 618 studies published before September 2013 using the same criteria.
In total we found eight major groups of animal pathogens that are transmitted potentially at flowers including a trypanosomatid fungi bacteria
and RNA VIRUSES they note. Their paper Arranging the bouquet of disease: Floral traits and the transmission of plant and animal pathogens was featured in the publisher's News Round up of most newsworthy research.
Traditionally research on flower evolution has focused largely on selection by pollinators but as Mcart and colleagues point out pollinators that also transmit pathogens may reduce the benefits to the plant of attracting them depending on the costs and benefits of pollination.
whether a flower's chemical or physical traits determine the likelihood that pathogens are transmitted for example
From the pollinator's perspective there has been surprisingly little work elucidating the role of flowers and floral traits for pathogen transmission.

Using large wheat variety trials provided by Kalyx Australia the team looked at yield loss of different cultivars (plants chosen for breeding because of desirable characteristics)
They compared cultivars with disease-sensitivity genes to cultivars that lacked these particular genes and were able to show that the cultivars lacking the gene showed no yield loss and in some instances increased yields in the presence of disease.
From this the team were able to conclude if a sensitivity gene was eliminated there would be associated minimal risks

which reveals the oldest evidence of sexual reproduction in a flowering plant--a cluster of 18 tiny flowers from the Cretaceous period--with one of them in the process of making some new seeds for the next generation.
when flowering plants were changing the face of the Earth forever adding beauty biodiversity and food.
It appears identical to the reproduction process that angiosperms or flowering plants still use today. Researchers from Oregon State university and Germany published their findings on the fossils in the Journal of the Botanical Institute of Texas. The flowers themselves are in remarkable condition as are many such plants
and insects preserved for all time in amber. The flowing tree sap covered the specimens
and then began the long process of turning into a fossilized semiprecious gem. The flower cluster is one of the most complete ever found in amber
and appeared at a time when many of the flowering plants were still quite small. Even more remarkable is the microscopic image of pollen tubes growing out of two grains of pollen
and penetrating the flower's stigma the receptive part of the female reproductive system. This sets the stage for fertilization of the egg and would begin the process of seed formation--had the reproductive act been completed.
In Cretaceous flowers we've never before seen a fossil that shows the pollen tube actually entering the stigma said George Poinar Jr. a professor emeritus in the Department of Integrative Biology at the OSU College of Science.
This is the beauty of amber fossils. They are preserved so rapidly after entering the resin that structures such as pollen grains
