We present a siamese adaptation of the Long Short-Term Memory (LSTM) network for labeled data comprised of pairs of variable-length sequences. Our model is applied to assess semantic similarity between sentences, where we exceed state of the art, outperforming carefully handcrafted features and recently proposed neural network systems of greater complexity.(More)
Ephemeral wetland vegetation (EWV) in the Mediterranean Basin appears in temporary wetlands where favourable hydrological conditions exist only for a short time and year-to-year variability is high. Here, we report results of the seed germination, dormancy and desiccation tolerance of eight annual species living in this vulnerable habitat. Experiments were(More)
We introduce principal differences analysis (PDA) for analyzing differences between high-dimensional distributions. The method operates by finding the projection that maximizes the Wasserstein divergence between the resulting univari-ate populations. Relying on the Cramer-Wold device, it requires no assumptions about the form of the underlying(More)
Seed germination is the most important transitional event between early stages in the life cycle of spermatophytes and understanding it is crucial to understand plant adaptation and evolution. However, so far seed germination of phylogenetically closely related species has been poorly investigated. To test the hypothises that phylogenetically related plant(More)

To meet the demand for sustainable forest management, especially in terms of climate change and subsequent risks, planning and decision-making becomes increasingly important (Pretzsch et al. 2008). Simulation models support forest planning since they allow studying future scenarios thus facilitating the decision-making process. Within the scope of the(More)
Crop wild relatives are an important source of new genetic diversity for plant breeding and crop improvement. Enset (Ensete ventricosum) is mainly cultivated as a multipurpose crop in Ethiopia, supplying food to 13 million people. To improve the agronomic traits of enset clonal lines, sexual propagation can be of key importance, in particular crossbreeding(More)
We hypothesized a geographical pattern of the plant performance (seedling development, biomass production, relative water content and chlorophyll content) as a result of response to the interaction between photoperiod and water availability in populations of the arctic-alpine Silene suecica from different latitudes, thus experiencing different photoperiods(More)
