#Tomato turf wars: Benign bug beats salmonella; tomato eaters winscientists from the U s. Food and Drug Administration (FDA) have identified a benign bacterium that shows promise in blocking Salmonella from colonizing raw tomatoes.
Their research is published ahead of print in the journal Applied and Environmental Microbiology. When applied to Salmonella-contaminated tomato plants in a field study the bacterium known as Paenibacillus alvei significantly reduced the concentration of the pathogen compared to controls.
Later in July they measured Sesarma populations (based on how many they could trap. In August they tethered crabs to make them more vulnerable to predators

and livestock watering stations provide predatory ravens with high perches from which to spy sage grouse nests.
They rigged the field centre's microscopes with smartphones to produce images of the tiny spider's even tinier genitals (using cooking oil from the station's kitchen to make them more translucent) dusted the spider's webs with puffs of corn flour (also from the kitchen) to make them stand out
#Stink bug traps may increase damage to tomato fruitsthe invasive brown marmorated stink bug (Halyomorpha halys) is an important pest of fruits and vegetables.
To counter them some home gardeners use pheromone-baited traps that are designed to attract trap
However new research from entomologists at the University of Maryland suggests that the traps may actually increase stink bug damage to tomatoes.
The researchers asked 15 gardeners to place stink bug traps at the ends of rows of tomatoes while another group of 14 placed no traps in their gardens.
but the the abundance of stink bugs on the tomato fruits was marginally greater in the gardens with traps
and the fruits sustained significantly more injury than tomato fruits grown in gardens without traps.
Furthermore tomato fruits on plants near the traps housed more stink bugs than tomato fruits on plants that were away from the traps.
and it appears that the addition of traps to gardens may increase injury to tomato fruits.
The increased damage may have resulted in part because of a phenomenon known as trap spillover which can occur
when pests arrive in the general vicinity of a trap and rest on vegetation before entering
and being captured by the trap. This study presents evidence that placement of an attract -and-kill stink bug trap near a plant may actually result in greater abundance of stink bugs on the fruit the researchers wrote.

or in some instances volcanically heated soil the maleo parents abandon their nest. After an incubation period of approximately 70 days the chicks emerge fully feathered able to fly
Nest abandonment is normal for sea turtles such as the olive ridley one of three threatened sea turtle species known to nest on the Binerean Cape area.
#Deer feeding puts birds at risk, research showsby comparing the fate of artificial nests close
and wild boar researchers found that those nests in the vicinity of feeding sites were depredated twice more.
in a radius of 1-km the probability of nest survival is lowered. When accounting for all feeding sites in the study region (ca 2000 km2) this would mean that in one fifth of the area ground-nesting birds will have little chance to see their eggs hatching.

#Birds of all feathers and global flu diversitya group of international scientists have completed the first global inventory of flu strains in birds by reviewing more than 50 published studies
They found that each trap attracted an average of 130 male moths--half the number of catches possible with synthetic pheromones
In total there were 641 independent Orangutan records taken at 1409 camera trap stations over 159152 trap days.
and plastic building materials to construct their nests. The research was published recently in the journal Ecosphere.
We found two solitary bee species using plastic in place of natural nest building materials which suggests innovative use of common urban materials.
Moore analyzed a grey goo that Macivor discovered in the nests of one kind of bee Megachile campanulae
Turns out that M. campanulae was occasionally replacing plant resins with polyurethane-based exterior building sealant such as caulking in its brood cells--created in a nest to rear larva.
In both cases larvae successfully developed from the plastic-lined nests. In fact the bees emerged parasite-free suggesting plastic nests may physically impede parasites the study said.
The nests containing plastic were among more than 200 artificial nest boxes monitored by Macivor as part of a large-scale investigation of the ecology of urban bees
and wasps a project involving numerous citizen scientists. The nest boxes are located in Toronto and the surrounding region in backyards community gardens
and parks and on green roofs. They are used by a variety of bee species. The novel use of plastics in the nests of bees could reflect the ecologically adaptive traits necessary for survival in an increasingly human-dominated environment Macivor said.

Once on the ground they dig a hole with their tails defecate in it and cover the pile with leaf litter.

With the right structure fur and feathers can generate efficient thermal insulation in the far infrared range
The team found more bird nests and greater species diversity in the no-till fields than in the tilled soybeans.
Nest losses were high however. About 80 percent of nests in the no-till fields and more than 90 percent in tilled fields failed
as a result of predation or the onset of farm operations before eggs hatched or young birds were ready to fly.
High mortality is fairly common in bird nests however and while the losses in no-till soybean fields were greater than those seen in pristine grasslands they were not much worse the researchers said.
--and we actually found a nest. The study adds to the evidence that agricultural practices can have a broad influence on bird abundance
Of the nests that failed 65.1 percent were raided by predators and 24.4 percent were lost to farm machinery during crop planting.
Continuously recording cameras trained on nests showed that coyotes were the primary predators of the ground-level nests--another surprise.
which are raised in open nests. Because hoatzins can fly short distances only the adult birds are also easy prey.
Another special feature of the Hoatzin are the claws on the wings of the chicks which enable the hatchlings to climb trees.

#How electricity helps spider webs snatch prey and pollutantsspider webs actively spring towards prey thanks to electrically-conductive glue spread across their surface Oxford university scientists have discovered.
The researchers found that the electrostatic properties of the glue that coats spider webs causes them to reach out to grab all charged particles from pollen and pollutants to flying insects.
'Electrical disturbances caused by spider webs are ranged extremely short so it is not yet clear whether insects would be able to sense them before the web snaps out to grab them.
so it's fascinating to see how spider webs make use of this to actively catch prey.

In addition to proximity to transmission lines ravens in the study area selected nest sites that were in close proximity to edges formed between sagebrush
