A walk on the wild sidefor most of history artificial selection on large herbivores was probably weak Marshall said Herders could not afford to kill many animals particularly large-bodied animals with long gestation periods.
Metritis develops after a cow gives birth when bacteria take advantage of the open vagina and cervix to settle in the uterus.
While heavy nitrogen fertilization could partially compensate for this decline in food quality it would also have negative consequences including higher costs more nitrate leaching into groundwater
so cross-pollination isn't possible; introducing genes to make both the male and female trees or plants sterile;
and supports wild bees in farms is not only an effective approach to helping enhance crop pollination
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

#UV exposure found to lower folate levels in young womenwomen who are pregnant or trying to fall pregnant and taking a folic acid supplement may be at risk of reducing their folate benefit through sun exposure a new QUT study has warned.
In a paper titled Exposure to solar ultraviolet radiation is associated with decreased folate status in women of childbearing age published in the Journal of Photochemistry and Photobiology B:
and during pregnancy Professor Kimlin said. Folate has been found to reduce miscarriage and neural tube defects such as spina bifida in unborn babies.
The NHMRC recommends pregnant women or those planning a pregnancy take 500 micrograms a day.
Professor Kimlin said the study which was the first to investigate the effects of sun exposure on folate levels in women of childbearing age found women who had high levels of sun exposure had folate levels below those recommended for women considering pregnancy.
The women at risk were those who were outside during the most UV intense time of the day between 10am
and the importance of folate in their diet especially those who are planning a pregnancy Dr Borradale said.
The results of this study reinforce the need for adequate folate levels prior to and during pregnancy.
Folic acid is A b vitamin that is very important for pregnant women and those planning a baby.
The impacts on wheat and soybean are likely to be less profound primarily because of the fertilisation effects that elevated levels of CO2 can have on these crops.
whether these CO2 fertilisation effects will actually occur in the field owing to interactions with other factors.
If the CO2 fertilisation effects do occur the researchers found that the yields of wheat
When the CO2 fertilisation effects are taken not into account the researchers found a net decrease in yields in all three crops intensified by extreme heat stress for the top-five producing countries of each crop.
unless CO2 fertilisation effects have been overestimated continued Deryng. However extreme heat stress reinforced by'business-as usual'reduces the beneficial effects considerably in these two crops.
Tree pollination in the Northeast has begun already according to Dr. Rosenstreich and lasts through early June
and fertilization can control ground-level light. Light appears to be very important in maintaining or losing biodiversity in grasslands.
The team also found elephants that gave birth twice in their teenage years had calves three times more likely to survive to independence than those born to mothers who had their first young after the age of 19.
#Half of pregnant women are passive smokers, due above all to their partners, Spanish study findsas shown in a study carried out by researchers at 13 research centres in Asturias Gipuzkoa Sabadell
and Valencia over half of nonsmoking pregnant women 55%are passive smokers. These women are under the effect of tobacco smoke to a considerable extent
which nonsmoking pregnant women from Asturias Gipuzkoa Sabadell and Valencia are exposed to tobacco smoke. To find out about tobacco exposure researchers based themselves on urine samples collected during the medical check-up in the third trimester of pregnancy
and on the responses the women gave to a set of questions. They studied 1783 women after rejecting another 480 who had displayed signs of being smokers according to their urine samples and the results of the surveys.

Specifically the level of cotinine in the pregnant women analysed in the study fell 16%.
In the case of pregnant women in Gipuzkoa exposure on the whole was found to be lower;
#Mothers diet linked to premature birth: fruits, vegetables linked to reduced risk of preterm deliverypregnant women who eat a prudent diet rich in vegetables fruits whole grains
Although these findings cannot establish causality they support dietary advice to pregnant women to eat a balanced diet including vegetables fruit whole grains
Preterm delivery (before 37 weeks of pregnancy) is associated with significant short and long term ill-health and accounts for almost 75%of all newborn deaths.
Using data from the Norwegian Mother and Child Cohort Study they analyzed preterm births among 66000 women between 2002 and 2008.
and completed a validated food frequency questionnaire on dietary habits during the first four to five months of pregnancy.
Preterm delivery was defined as delivery between 22 and<37 weeks of pregnancy. The researchers identified three distinct dietary patterns interpreted as prudent (vegetables fruits oils water as a beverage whole grain cereals poultry fibre rich bread) Western
Among the 66000 pregnant women preterm delivery occurred in 3505 (5. 3%)cases. After adjusting for several confounding factors the team found that an overall prudent dietary pattern was associated with a significantly reduced risk of preterm delivery especially among women having their first baby as well as spontaneous and late preterm delivery.
In an accompanying editorial Professor Lucilla Poston at King's college London says healthy eating in pregnancy is always a good idea.

the female's color or the behavior that accompanies different reproductive statuses. Females at different reproductive stages--fertile pregnant
Pregnant females retain their coloration until laying and very large orange spots suggest the female is swollen with eggs
But male behavior was determined more strongly by the female's reproductive status. Males also mated more frequently with fertile females than pregnant ones or those outside of the breeding cycle.
Frustrated males often behaved aggressively--with chases and bites--towards pregnant females. If males persist with sexually aggressive behavior pregnant females have a final ace up their sleeves--they flip over onto their backs

Results from the diagnostic developed by the lab of Rice bioengineer Rebecca Richards-Kortum are read from a paper strip that resembles a pregnancy test.
Honey bees provide ecosystem services through pollination of crops worth $215 billion annually worldwide. Concern over honey bee declines in recent decades as well as annual losses has sparked debate over their causes
and Canada collected seeds from several areas tested different fertilisation levels and took into account chemical and physical variations in the soil.
and pesticides that replace nature's services such as pollination and natural pest control diminish the importance of protecting ecosystems said LÃ pez-Hoffman
Based on data from the study it is estimated that treatment with low-cost bubble CPAP could save the lives of 178000 low-birth-weight babies in Africa each year.
The researchers found that premature infants with complications like sepsis very low birth weight and respiratory distress syndrome (RDS) benefited most from the new technology.
Premature birth is now the second leading cause of death among children worldwide and most premature babies are born in low-resource settings where many of the basic technologies

Methane consumption pest suppression pollination and bird populations were higher in perennial grasslands. In addition the team found that the grass crops'ability to harbor such increased biodiversity is linked strongly to the fields'location relative to other habitats.
If high commodity prices continue to drive conversion of these marginal lands to annual crop production it will reduce the flexibility we have in the future to promote other critical services like pollination pest suppression and reduction of greenhouse gasses.
If it is missing fertilization will not occur. Our findings indicate that genetic defects in TMEM95 could also cause infertility in men elaborates Pausch.
#EU policy is driving up demand for pollination faster than honeybee numbersresearch conducted by the University of Reading's Centre for Agri-Environmental Research
and the Insect Pollinators Initiative Crops project indicates that demand for pollination services has risen five times as fast as the number of colonies across Europe.
The study led by Professor Simon Potts compared the number of available honeybee colonies in 41 European countries with their demands for pollination services in the years 2005 and 2010.
although the total number of honeybee colonies increased in some European countries the demands for the pollination services supplied by these pollinators has increased much faster due to the increasing demand for biofuel feedstocks.
and Italy honeybee stocks were found to be insufficient to supply these pollination services alone.
Many of the most important crops in Europe such as rapeseed sunflower soybeans apples and strawberries benefit from pollination by insects.
This sets the stage for fertilization of the egg and would begin the process of seed formation--had the reproductive act been completed.

In 1952 The british Nobel zoologist Peter Medawar proposed that aging is the simple result of the failure of natural selection to maintain fitness in older animals with declining fertility.
As fertility wanes, then the chances to correct inappropriate gene expression via natural selection also decline, generating the aging phenotype.
