• Premise of the study: Permineralization provides the most faithful known mode of three-dimensional preservation of the morphology and cellular anatomy of fossil plants. Standard optical microscopic ...

Genetic patterns of habitat fragmentation and past climate-change effects in the Mediterranean high-mountain plant Armeria caespitosa (Plumbaginaceae)... 16 Aug 2013 | 03:14 am

• Premise of the Study: Mountain plants are among the species most vulnerable to global warming, because of their isolation, narrow geographic distribution, and limited geographic range shifts. Stocha...

Genetic and morphological structure of a spruce hybrid (Picea sitchensis x P. glauca) zone along a climatic gradient [Population Biology] 16 Aug 2013 | 03:14 am

• Premise of the study: Historic colonization and contemporary evolutionary processes contribute to patterns of genetic variation and differentiation among populations. However, separating the respect...

Seed-mediated connectivity among fragmented populations of Quercus castanea (Fagaceae) in a Mexican landscape [Population Biology] 16 Aug 2013 | 03:14 am

• Premise of study: Anthropogenic fragmentation is an ongoing process in many forested areas that may create loss of connectivity among tree populations and constitutes a serious threat to ecological ...

A total evidence approach to understanding phylogenetic relationships and ecological diversity in Selaginella subg. Tetragonostachys [Pteridology] 16 Aug 2013 | 03:14 am

• Premise of the Study: Several members of Selaginella are renowned for their ability to survive extreme drought and "resurrect" when conditions improve. Many of these belong to subgenus Tetragonostac...

Temperature regulates positively photoblastic seed germination in four ficus (moraceae) tree species from contrasting habitats in a seasonal tropical ... 16 Aug 2013 | 03:14 am

• Premise of the Study: Differences in seed germination responses of trees in tropical forests to temperature and light quality may contribute to their coexistence. We investigated the effects of temp...

Climate drives vein anatomy in Proteaceae [Anatomy and Morphology] 16 Aug 2013 | 03:14 am

• Premise of study: The mechanisms by which plants tolerate water deficit are only just becoming clear. One key factor in drought tolerance is the ability to maintain the capacity to conduct water thr...

Fruit structure in Magnoliaceae s.l. and Archaeanthus and their relationships [Anatomy and Morphology] 16 Aug 2013 | 03:14 am

• Premise of the study: The family Magnoliaceae s.l. is a basal angiosperm family with two subfamilies—Magnolioideae and Liriodendroideae, which differ by the types and structure of their fruits and s...

Anatomical and physical changes in leaves during the production of tamales [Biomechanics] 16 Aug 2013 | 03:14 am

• Premise of the study: Tamale preparation has a long tradition in Mexico. To understand which material properties have been considered important for this purpose throughout the years, a study was con...
