Integrating the Water Framework Directive into the Habitats Directive: Analysis of distribution patterns of lacustrine EU habitats in lakes of Lombardy (northern Italy)

Journal of Limnology, 2017
The existence of strong potential synergies between the Water Framework Directive (WFD) and the Habitats Directive (HD) is widely acknowledged. Indeed, ensuring favourable conservation conditions for aquatic habitats and species of conservation concern ...

Auxin response and PIN‐mediated transport in chlorophyte algae

Journal of Integrative Plant Biology, EarlyView.
Like multicellular plants, green algae respond to auxin and move it across their cells. However, their PIN‐like proteins do not act like plant auxin exporters, suggesting that basic auxin transport evolved early and specialized directional transport appeared later in plant evolution.

Charophyte variation in sensitivity to eutrophication affects their potential for the trophic and ecological status indication

Knowledge and Management of Aquatic Ecosystems, 2021
Charophytes (stoneworts) form a group of macrophytes that are considered sensitive to eutrophication. The high indicator value of charophytes toward eutrophication results in their wide use in the bioassessment systems.

Endocranial anatomy of the earliest Cretaceous European neosuchian crocodyliform Pholidosaurus purbeckensis provides new evidence for the ecological evolution of Pholidosauridae

Journal of Anatomy, EarlyView.
We present new insights into the internal cranial anatomy of the neosuchian crocodyliform Pholidosaurus purbeckensis, based on CT‐scan data of material from the lowermost Cretaceous Purbeck Limestone Group, southern UK. From the study of the endocast, we obtained new information on the phylogeny and the ecological evolution of the Family ...

Phylogeny of characeae based on 18S rDNA, rbcL and atpB gene sequences

四川大学学报. 自然科学版, 2020
In order to find a suitable molecular marker for the classification of Charophytes, some of the Charophytes were used as material to make a phylogenetic study by analyzing the diversity of 18S rDNA、rbcL、atpB and 18S rDNA、rbcL、atpB threegene combination ...

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

Journal of Petroleum Geology, EarlyView.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

Comparative study of the oospore morphology of two populations of a rare species Chara baueri A. Braun in Cedynia (Poland) and Batzlow (Germany)

Acta Societatis Botanicorum Poloniae, 2012
Morphological features of oospores of Chara baueri A. Braun, one of the rarest charophyte species worldwide, were studied based on 100 oospores collected from a small and temporarily dried mid-field pond near Cedynia, Western Poland.

Charophytes of the Lubelszczyzna region (Eastern Poland)

Acta Societatis Botanicorum Poloniae, 2011
The distribution and ecology of charophytes in Lubelszczyzna (Eastern Poland) is described based on herbaria collections, literature data, and the author's own investigations. Maps showing the distribution of all 22 charophyte species identified so far are presented, as well as the details of habitats ecology.
