Lungenwurm-Wetter

Bei warmfeuchtem Wetter muss damit gerechnet werden, dass Weiderinder mit Lungenwürmern infiziert werden

Augustus Peter Wetter

Augustus Peter Wetter was born in Germany in 1829 and died in Pennsylvania in 1882. He came to Savannah before the civil War and was one of the wealthiest men in Savannah for a period of time. Augustus P. Wetter was many things; he was a Civil Engineer, a planter, an Alderman for Savannah\u27s first district and Cotton press director, just to name a few. He also held many positions on committees and boards. His life contained many triumphs and tragedies that would indicate a very full and sometimes sad existence.https://digitalcommons.georgiasouthern.edu/sav-bios-lane/1114/thumbnail.jp

It Gets Wetter

It\u27s a novel scene—New York City, 123 years from now: half-drowned but not out. Still a capital of real estate, still a political powerhouse, still an unequal battleground between finance and housing movements, still a crucible where capitalism and climate politics are smashed, melted, and twisted together. The (true) physical premise is that upper Manhattan is fifty feet higher than lower Manhattan

Es herrscht Lungenwurm-Wetter

Bei warmfeuchtem Wetter muss damit gerechnet werden, dass Weiderinder mit Lungenwürmern infiziert werden. Rinder können zwar eine körpereigene Abwehr aufbauen, diese ist jedoch zeitlich begrenzt. So verlieren Tiere auf der Alp ihre Abwehrkräfte, oder Jungtiere bauen keine auf und sind dann auf der Herbstweide gefährdet

Tests for attraction to prey and predator avoidance by chemical cues in spiders of the beech forest floor

Spiders leave draglines, faeces and other secretions behind when traveling through their microhabitat. The presence of these secretions may unintentionally inform other animals, prey as well as predators, about a recent and possible current predation risk or food availability. For a wolf spider, other spiders including smaller conspecifics, form a substantial part of their prey, and larger wolf spiders, again including conspecifics, are potential predators. We tested two hypotheses: that large wolf spiders may locate patches of potential spider prey through the presence of silk threads and/or other secretions; and that prey spiders may use secretions from large wolf spiders to avoid patches with high predation risk. We used large (subadult or adult) Pardosa saltans to provide predator cues and mixed dwarf spiders or small (juvenile) P. saltans to provide prey cues. Subadult wolf spiders were significantly attracted to litter contaminated by dwarf spiders or small conspecifics after 6 hours but no longer after 24 hours. In contrast, neither dwarf spiders nor small P. saltans showed significant avoidance of substrate contaminated by adult P. saltans. However, small P. saltans showed different activity patterns on the two substrates. The results indicate that wolf spiders are able to increase the efficiency of foraging by searching preferentially in patches with the presence of intraguild prey. The lack of a clear patch selection response of the prey in spite of a modified activity pattern may possibly be associated with the vertical stratification of the beech litter habitat: the reduced volume of spaces in the deeper layers could make downward rather than horizontal movement a fast and safe tactic against a large predator that cannot enter these spaces

Contributions toward a bryoflora of the Aberdare Range, Kenya

124 species of bryophytes, belonging to 46 families are reported for the Aberdare Mountains, of which 58 species are new for the Aberdares and 6 records are new for Kenya, indicated by * and ** respectively. The wetter, more humid southern and south-eastern parts of the range contain the greatest diversity of species, particularly in the montane forests while the drier northern part is poor in species
