How then do obligately asexual genotypes and populations survive the harsh winter conditions? Extensive winter sampling of two, largely obligately, asexual populations of S. lacustris in Oxfordshire, UK, demonstrate that adult individuals can survive over the winter, but at densities way below that ...

Wireworms Insect Seeds hollowed; seedlings severed; stunting/wilting; roots eaten; tubers/bulbs bored. Trap by digging 2- to 4-inch-deep holes every 3 to 10 feet, fill with mix of germinating beans/corn/peas or potato sections as bait, cover with soil or a board, in 1 week uncover an...
How can these animals survive so far from the sunlight, under these extreme conditions? In the water, scientists found species of bacteria that split hydrogen sulfide from the water to get energy to make organic compounds (chemosynthesis). The tubeworms have bacteria in their tissues that help ...
Destroy affected plants, and do not replant in the same place for two years. Smut spores can survive in the soil for two years. Stewart’s wilt is a bacterial disease spread by flea beetles. Stewart’s wilt will cause leaves to yellow and plants to become stunted. Plant disease-resistant...
Bees use the honey for food and store enough to survive the winter. At first glance, bees don't appear to be very active or need much food during the winter. They leave their hives only to relieve themselves, since they do not defecate in their living space. But while inside the hive...
Sudden death stories of democracy do us a disservice. The truth is that democracy can be destroyed in multiple ways, at different tempos. The slowest of these – environmental degradation – is a consequence of the anthropocentric ideal underlying democr
A bug in the ear may survive for a few hours to a day, depending on factors like oxygen availability, moisture, and thebug's size and type. Smaller insects may survive longer if they don’t get dislodged, whilelarger insects or those affected by earwax or moisture may die more quickly....
