Flowering Agri-environment Schemes Easily Enhance Pollinators
2013-06-10 13:43:51

Pensoft Publishers Agri-environment schemes aimed to promote biodiversity on farmland have positive effects on wild bees, hoverflies and butterflies. Effects on diversity and abundance were strongest when agri-environment schemes prescribed sowing wild-flowers, the more flowering species the better. Organic farms, set-aside land or fields receiving reduced amounts of fertilizer and pesticides generally hosted more wild pollinators than conventionally farmed land. Jeroen Scheper of Alterra...

Pollination Is Just One Production Factor Among Many
2013-06-06 11:27:09

ETH Zurich No food for the human race without bees? It is not quite as straightforward as that. A case study by ecologists from ETH Zurich in a coffee-growing area in India reveals that pollinating insects are just one production factor among many. Farmers have several possibilities to increase their harvest. All over the world, bees are dying and insect diversity is dwindling. Only recently, both the media and scientists expressed fears that insect pollination is in decline, which...

Ants and Bugs Be Gone, a Portland pest control company is now providing exterminator services in Portland Metro and the surrounding areas. Portland, OR (PRWEB) June 04, 2013 Pest control services in Portland this time of year are in demand as sugar ants begin to become invasive and move in and out of the home on a regular basis. Ants and Bugs Be Gone owner Chris Nelson says "We are seeing spiders moving around earlier than ever before. This nice weather has made it easier for them to move...

Bull Ants Work Inefficiently At Night
2013-05-28 10:29:12

Brett Smith for redOrbit.com - Your Universe Online Nocturnal Australian bull ants have trouble commuting in the dark, making those that head out and return the most efficient workers, according to a new study that was recently published in the journal PLOS ONE. “To cope with dim or dark environments, night-active ants have larger lenses and wider photoreceptors — to capture light — compared to their day-active relatives,” said co-author Ajay Narendra, at the...

First Definitive Proof Of Bacteria-feeding Behavior In Green Algae
2013-05-24 12:41:52

[ Watch The Video Scientists Prove Green Algae´s Appetite for Bacteria ] American Museum of Natural History A team of researchers has captured images of green alga consuming bacteria, offering a glimpse at how early organisms dating back more than 1 billion years may have acquired free-living photosynthetic cells. This acquisition is thought to have been a critical first step in the evolution of photosynthetic algae and land plants, which, in turn, contributed to the increase in...

Bee Biodiversity Improving
2013-05-22 09:59:52

Brett Smith for redOrbit.com - Your Universe Online With beekeepers around the world still reporting a high rate of colony collapse, a new study from the University of Leeds comes as an encouraging sign for those worried about the level of bee biodiversity. In collaboration with Naturalis Biodiversity Centre in the Netherlands, the Leeds researchers found a dramatic drop in the amount of biodiversity in many species throughout Britain, Belgium and the Netherlands between the 1950s and...

Middle American Stenamma Ant's Peculiar Life History
2013-04-25 21:35:17

Pensoft Publishers Some ant species use clay 'door-pebbles' for the protection of their nest Stenamma is a cryptic "leaf-litter" ant genus that occurs in moderately humid to wet forest habitats throughout the Holarctic region, Central America, and part of northwestern South America (Colombia and Ecuador). The genus was thought to be restricted primarily to the temperate zone, but recent collecting efforts have uncovered a large variety of Neotropical forms, which rival the Holarctic...

Flower's Nectar Content Changed By Ants
2013-04-25 13:55:58

American Journal of Botany Ants foraging on nectar transmit yeasts that change sugar-chemistry and may affect subsequent pollinator visitations and plant fitness Ants play a variety of important roles in many ecosystems. As frequent visitors to flowers, they can benefit plants in their role as pollinators when they forage on sugar-rich nectar. However, a new study reveals that this mutualistic relationship may actually have some hidden costs. By transmitting sugar-eating yeasts to the...

Sebae Clownfish, Amphiprion sebae
2013-02-17 07:52:18

Image Credit: Miles Wu/Wikipedia (CC BY-SA 2.0) The sabae clownfish is a very rare species in the wild and is aggressive, especially as it matures. It is found in the northern Indian Ocean around India, Sri Lanka, Arabian Peninsula, Andaman Islands, Sumatra, Indonesia, and the Maldive Islands. This fish inhabits lagoons and coastal waters around reefs, at a depth range of 6 - 75 feet. This species of fish is the most popular fish for home aquariums. The body of the sabae clownfish is...

Image Caption: Amphiprion polymnus at Tasik Ria House reef, North Sulawesi, Indonesia. Credit: Jens Peterson/Wikipedia (CC BY-SA 3.0) Saddleback clownfish are found in harbors and lagoons with a soft or sandy bottom, around reefs at depths from 6 - 90 feet. This fish is native to the Western Pacific, around China, Viet Nam, Gulf of Thailand, Indonesia, Philippines, northern Australia, New Guinea, New Britain, and the Solomon Islands. The body of the saddleback clownfish ranges in color...

Convict Blenny, Pholidichthys leucotaenia
2013-01-03 15:48:38

The convict blenny lives in tunnels around coastal reefs and in shallow lagoons of the Western South Pacific, mainly from the Philippines to the Solomon Islands. The young of this fish will often swim in schools around the reef heads and ledges so tightly packed together they will look like one organism. This species, sometimes called a blenny and sometimes called a goby, actually it is neither. It is in a classification alone with one other species called a worm blenny. The convict blenny...

The Polydnaviruses (PDV) are a family of insect viruses that contain two genera: Ichnoviruses (IV) and Bracoviruses (BV). The ichnoviruses occur in ichneumonid wasps and bracoviruses in braconid wasps. The virus is composed of multiple segments of double-stranded superhelical DNA packaged in capsid proteins and a double layer or single layer envelope. The full genome of the virus is integrated into the genome of the wasps and the virus only replicates in specific cells in the female...

The ants, one of the most successful groups of insects, are of particular interest because they form advanced colonies, and can constitute up to 15 percent of the total animal biomass of a tropical rainforest. They belong to the order Hymenoptera and are close relatives of the vespoid wasps. Ants appear in amber, found in central New Jersey, believed to be from the Cretaceous period. It is thought that they evolved from the wasps that had appeared during the Jurassic period. They are...
