73 new references for 72 taxa of vascular plant are here reported the Madeira archipelago. 55 not previously recorded Desertas Islands, 12 to Porto Santo Island and 6 Island. Of taxa, 28 xenophytes, 10 flora archipelago (of these 9 xenophytes). Their native status, taxonomy distribution briefly discussed.
Pyrus magyarica was considered as a “superendemic” species of the Carpathian Basin for a long time; however, despite its presumed significance, doubts about its taxonomical status have been raised. the confusions originate from the invalidity of the description and the lack of type material. latter interpretations are not consistent and contradict the description of the species in the protologu...
1. The search for general characteristics of invasive species has not been very successful yet. A reason for this could be that current invasion patterns are mainly reflecting the introduction history (i.e. time since introduction and propagule pressure) of the species. Accurate data on the introduction history are, however, rare, particularly for introduced alien species that have not establis...
The taxonomy of fungal species, similar to that of many other microorganisms, suffers frequent revisions due to the discovery of new species and to the development and gathering of characterization data and morphological information. Morpho-taxonomy helps in the identification of many species. This work presents the macro, micro-morphological, and spectral mass analyses for phenotypic character...
In this paper, we consider the problem of applying ATM technology in designing distributed industrial plant control applications with integrated real-time communication requirements. In particular, we rst examine (1) the design space using current ATM service categories and their corresponding tra c models, and (2) the mathematical and practical implications of the tra c models. We then present...

Taxonomic arrangements for the cormorants and shags (Phalacrocoracidae) had varied greatly until two quite similar arrangements, one based on behavior and the other on osteological characters, became the basis for current thought on the evolutionary relationships of these birds. The terms cormorant and shag, which had previously been haphazardly applied to members of the group, became the verna...
We present a new supertree method that enables rapid estimation of a summary tree on the scale of millions of leaves. This supertree method summarizes a collection of input phylogenies and an input taxonomy. We introduce formal goals and criteria for such a supertree to satisfy in order to transparently and justifiably represent the input trees. In addition to producing a supertree, our method ...
As adults, we think about the biological world in different ways than other realms. We are, for example, more inclined to see purposes of just the parts of animals and plants and not of the plant or animal as a whole, but we happily do so for artifacts (1). We see living kinds as occupying relatively unique locations in taxonomies (2). We make a much richer set of inferences about shared proper...
