The Ectocarpus genome and the independent evolution of multicellularity in brown algae

2010

Brown algae (Phaeophyceae) are complex photosynthetic organisms with a very different evolutionary history to green plants, to which they are only distantly related. These seaweeds are the dominant species in rocky coastal ecosystems and they exhibit many interesting adaptations to these, often harsh, environments. Brown algae are also one of only a small number of eukaryotic lineages that have evolved complex multicellularity (Fig. 1). We report the 214 million base pair (Mbp) genome sequence of the filamentous seaweed Ectocarpus siliculosus (Dillwyn) Lyngbye, a model organism for brown algae, closely related to the kelps (Fig. 1). Genome features such as the presence of an extended set of…

Cohabitation of tree holes by ants and breeding birds in a temperate deciduous forest

2015

A previously unknown association of ants with birds breeding in tree holes is described. Ants Lasius brunneus Latreille (Hymenoptera: Formicidae) were found in c. 15% of nests of Parus major L. and Poecile palustris L. (Paridae) breeding in tree holes in the primeval deciduous forest located in the Białowieża National Park (Poland). The ants preferably used holes located higher above the ground. As such holes are warmer than the unused holes or other nest sites, it is suggested that the ants cohabit holes utilized by the tits to gain thermal benefits.

Nacionālā identitāte un interese par tradicionālo kultūru ir nozīmīgs faktors spēcīgas, inteliģentas personības veidošanā, un agrīnajā pusaudžu vecumposmā praktiska…

Pre-marital and pre-unional financial agreements and their circulation in the context of the new EU regulations 2016/1103 and 2016/1104

2021

Regulations (EU) 2016/1103 and 2016/1104 provide spouses and partners with the possibility to conclude agreements for the organization of their property regime but do not detail their content and structure. Moreover, while the possibility to conclude those agreements even prior to the marriage or the conclusion of a registered partnership is a valuable innovation in comparison with other European Regulations in family matters, some choices made by the European legislator on applicable law will likely be source of inconveniences. Furthermore, as for their recognition and enforcement in the participating Member States ? which will be based on the same rules enacted for decisions, authentic in…

The tools like evidences of metal working? : strike supports, abrasives and burnishers, sharpening tools and crushing tools

2013

Lots of lithic tools are present in Metal Ages, but few are studied. In metal production, they are especially constitued by strike supports, abrasives, burnishers, sharpening tools and crushing tools. A part of them are in metal ( strike supports) or in ceramic (abrasives, sharpening tools). Contemporary forms of these tools are too different to permit a dierct comparison. It is necessary to work on the function of the tools, deduced from the analysis of these structure. Strike supports used for metal working are easily identifiable. They allow to reproduce more or less precisely the objects that they were fabricated with. Abrasives are difficult to relate to a material, but the traces of u…

Floral ontogeny, petal diversity and nectary uniformity in Bruniaceae

2006

Bruniaceae are a small family subendemic to the Cape Floristic Region. Flowers are actinomorphic, choripetalous, pentamerous and tetracyclic. The petals show diverse adaxial swellings, which have been quoted as an example of diplophylly. Developmental studies confirm the true choripetaly of the flowers, thus pointing to an affinity to the Apiales within the euasterids II. They reject, however, the hypothesis of diplophylly as the petal swellings grow out rather late and are not vascularized. According to the position, size and shape of the swellings, six petal types are distinguished, which in part have phylogenetic information. Nectaries occur on the upper part of the ovary. Nectar is exuded …

Mediterranean Great Conversation

2015

The exit from the Mediterranean emergency requires rethinking its identity in a new perspective. This means recognizing its legitimate role as a “Great Sea in Between”, as a cultural interface able to connect all the citizens that address to it, in everyday life and as individuals, involving them in a real “great conversation” based on the design disciplines. Design, Brand, Visual Identity, Packaging, Social Media, Fashion, Food, Architecture, Music may be powerful antidotes to the immobility of those who mourn a lost Mediterranean harmony and also a viable alternative to the ethnic closure led by the proponents of the Clash of Civilizations.

Prote Hyle. Notions of Matter in the Platonic and Aristotelian Traditions

2017

How do we experience matter? Does it present itself to the senses? Or is it only an empty substratum that cannot be grasped if deprived of all sensible qualities? Is it perceived as a continuum, or rather intellectually reconstructed through mental and logical forms? Or is it that the very idea of a continuum is itself the outcome of mental abstraction? The nature of matter has been a central issue for philosophy since its inception. The constant oscillation of ancient thought between ma er as indeterminateness that does not have a concept and does not even properly exist - and matter as a principle that allows one to think plurality and otherness, that reaches even into the realm of the in…

Data from: Ancient symbiosis confers desiccation resistance to stored grain pest beetles

2017

Microbial symbionts of insects provide a range of ecological traits to their hosts that are beneficial in the context of biotic interactions. However, little is known about insect symbiont-mediated adaptation to the abiotic environment, e.g. temperature and humidity. Here we report on an ancient clade of intracellular, bacteriome-located Bacteroidetes symbionts that are associated with grain and wood pest beetles of the phylogenetically distant families Silvanidae and Bostrichidae. In the saw-toothed grain beetle Oryzaephilus surinamensis, we demonstrate that the symbionts affect cuticle thickness, melanization and hydrocarbon profile, enhancing desiccation resistance and thereby strongly i…
