Black carpenter ants(Camponotuspennysylvanicus) are native to Canada and eastern and central America where they can be found in most woodland areas. They nest in trees and dead wood, although they are classed as a pest because they frequently cause damage to the structure of houses and other ...
Infection responses (IR; virulent/avirulent) were scored at seven days after inoculation on the central part of leaf segments on a scale 0–4, where 0 is equivalent to no visible mycelium or sporulation, and 4 represents strong mycelial growth and sporulation89. Scoring was repeated one day ...
The Polar/Subpolar Zone is present near the poles in both the Northern and Southern Hemispheres. Towards the equator it is limited by the polar tree lines (see Boreal Zone) or by sea coasts. The entire zone covers 22 million km2, 15% of the land area of the earth, of which 14 millio...
The latitudinal diversity gradient—the tendency for more species to occur toward the equator—is the dominant pattern of life on Earth, yet the mechanisms responsible for it remain largely unexplained. Recently, the analysis of global data has led to ad
Prolonged periods without pre- cipitation in spring, as evidenced by recent observations in Central Europe (IPCC 2021), prevent timely and rapid germination of tree seeds and could perhaps lead to an accelerated loss of germination capacity (reduced lifespan) of the seeds. The already extreme ...
