Abstract:
... The present investigation presents a clear differentiation between the articulated and non-articulated stem of Selaginella, based on morphological and anatomical characteristics. We also take the first step in developing a clear definition of the articulated stem in Selaginella. Further, in Selaginella anaclasta previously described as having articulate stems, we found no micro-morphological or st ...

Abstract:
... Clonal integration between connected ramets within genets can increase their survival and growth. Different clonal plants form ramets in a variety of ways, and a number of species form more than one type of ramets. We tested for the first time whether effects of clonal integration can differ between different types of ramets within the same species. We compared effects of severing connections betw ...

Abstract:
... Fern sporangia may provide an important source of energy for bird species, which in turn can act as potential dispersers of viable spores. This study reports the first case of fern spore dispersal by land birds. We document the consumption of fern sporangia and evaluate the potential spore dispersal by Galápagos finches on Santa Cruz Island. Overall, 18% of the 34 sampled individuals of three finc ...

Abstract:
... Physical space, defined by its volume and shape, is considered a resource for plant growth, as a plant can be limited by physical space even when other resources (e.g., light, water and nutrients) are unlimited. However, the effect of physical space limitation on intraspecific competition of plants, especially floating plants, is not well understood. Here we tested the hypothesis that physical spa ...

For this study, we opted for a simple random sampling method, using the phytoecological method for the study of the flora. A statistical analysis of field data was processed by ADE.4, an analysis that highligh ...

Abstract:
... Fern spores and seeds initiate germination with fast water uptake, followed by a stationary phase with no appreciable water uptake and biochemical and metabolic processes that precede germination. After that, seed, germination is avoided by dehydration, as part of the priming treatments. After dehydration, seeds maintain their metabolic advances (hydration memory). As a result, rehydrated seeds ge ...

Abstract:
... Epidermal cells of leaves are diverse: tabular pavement cells, trichomes, and stomatal complexes. Pavement cells from the monocot Zea mays (maize) and the eudicot Arabidopsis thaliana (Arabidopsis) have highly undulate anticlinal walls. The molecular basis for generating these undulating margins has been extensively investigated in these species. This has led to two assumptions: first, that partic ...
