The dynamics of changes in an important economic trait sweet pepper “average fruit weight” and the manifestation heterosis have been studied on example 10 hybrids their parental lines with multiple harvests unheated film greenhouse. It was found that average weight, regardless its value, maximum relatively stable during first 5 harvests, which corresponds to return early yield month fruiting. A...

Red-tailed black-cockatoos are specialist feeders, relying almost entirely on the seeds of brown and desert stringybark (Eucalyptus baxteri and E. arenacea) and buloke trees (Allocasuarina luehmannii). The cockatoos feed almost entirely on the stringybark species that has fruited most recently and there are marked periods of food shortage between new crops. For a period of 2-3 months in late su...

We compare biogeographic and morphological parameters of two agamic complexes western North American hawthorns so as to evaluate possible explanations the differences in range between sexually reproducing taxa their apomictic sister taxa. have documented range, breeding system, morphology, leaf vascular architecture, niche breadth these hawthorns, for which phylogenetic relationships ploidy lev...

Aim Climate change causes shifts in species ranges globally. Terrestrial plant often lag behind temperature shifts, and it is unclear to what extent animal-dispersed plants can track climate change. Here, we estimate the ability of bird-dispersed future on a tropical mountain. Location Tropical elevational gradient (500–3500 m.a.s.l.) Manú biosphere reserve, Peru. Time period From 1960–1990 206...
