Leaf Lifespans of Chilean Proteaceae
Although comparative studies have revealed much about the environmental correlates of leaf lifespan and its integration with other leaf traits, a comprehensive theory of leaf lifespan is still lacking. The influence of growth rate on self-shading may be a key proximate determinant of both interand intra-specific variation in leaf lifespans. If this were the case, we would expect leaf lifespans ...
متن کاملGiant cuticular pores in Eidothea zoexylocarya (Proteaceae) leaves.
Ubiquitous, large diameter pores have not previously been adequately demonstrated to occur in leaf cuticles. Here we show conclusively that such structures occur in Eidothea zoexylocarya, a rainforest tree species of Proteaceae restricted to the Australian Wet Tropics. The pores are abundant, large-diameter apertures (∼1 μm), that extend perpendicularly most of the way through the cuticle from ...
متن کاملHost specificity and speciation of Mycosphaerella and Teratosphaeria species associated with leaf spots of Proteaceae
Species of Mycosphaerella and Teratosphaeria represent important foliicolous pathogens of Proteaceae. Presently approximately 40 members of these genera (incl. anamorphs) have been recorded from Proteaceae, though the majority are not known from culture, and have never been subjected to DNA sequence analysis. During the course of this study, epitypes were designated for several important specie...
متن کاملCovering a laminar family by leaf to leaf links
The Tree Augmentation Problem (TAP) is: given a tree T = (V, E) and a set E of edges (called links) on V disjoint to E , find a minimum size edge subset F ⊆ E so that T +F is 2-edge-connected. TAP is equivalent to the problem of finding a minimum size edge-cover F ⊆ E of a laminar set-family. We consider the restriction LL-TAP of TAP to instances when every link in E connects two leaves of T . ...
متن کاملCircumscription of Botryosphaeria species associated with Proteaceae based on morphology and DNA sequence data.
Botryosphaeria spp. occur on and cause diseases of Proteaceae, but accurate identification has been problematic due to the lack of clear species circumscriptions of members of this genus. In this study, 46 isolates of Botryosphaeria from proteaceous hosts growing in various parts of the world were studied, using morphology, cultural characters and sequence data from the ITS region of the rDNA o...
