Effect of Previous-Winter Mortality on the Association between Summer Temperature and Mortality in South Korea

متن کاملWinter Fruit Removal in Four Plant Species in Maine
We monitored individual plants of winterberry (Ilex verticil/ala), highbush cranberry (Viburnum opulus), wild lily-of-the-valley (Maianthemum canadense), and partridgeberry (Mitchel/a repens) during two reproductive seasons to measure the disappearance of fruits (presumably removed by fruit-eating animals) in plant species whose fruits ripen in early fall but persist through the winter. Pattern...

متن کاملThe population of Carassius gibelio (Bloch, 1782) and its parasites in Madatapa Lake (South Georgia)
Gibel carp is a very successful invasive fish species in the waters of Georgian inland and the only fish species in Lake Madatapa. However, almost nothing is known about its biology and morpho-ecological peculiarities at the national level and even the distribution data is not documented. For the first time, we studied the population characteristics of gibel carp in Lake Madatapa (South Georgia...
