Corrigiola litoralis (Caryophyllaceae) : Verbreitung, Ökologie und Vergesellschaftung im Elbe-Weser-Gebiet

Von der im Elbe-Weser-Gebiet seltenen Corrigiola litoralis wurden rezente Vorkommen in der Bremer Umgebung am Weserufer zwischen Achim und Verden sowie auf Sandböden in der Weser-Aller-Aue gefunden. Der Rückgang der Art in den letzten 100 Jahren wird durch Funddaten von Herbarbelegen, aus der Literatur sowie aktuellen Kartierungen belegt. Die Standorte von Corrigiola litoralis lassen sich in drei Typen gruppieren: 1) Flußufer, 2) Sandböden in Heiden sowie 3) Schotterflächen auf Bahn- und Industrieanlagen. Es handelt sich um offene Pionierstandorte mit skelettreichen basenarmen und wechselfeuchten Böden. An der Weser kommt Corrigiola zusammen mit Chenopodium rubrum. C. glaucum, Atriplex prostrata und Polygonum lapathifolium ssp. danubiale vor. Diese Artenkombination läßt sich dem Polygono brittingeri-Chenopodietum rubri zuordnen, zu dem an der Weser auch Xanthium albinum gehört.Recent findings of Corrigiola litoralis, a rare species in the Elbe-Weser area, were made near Bremen at the Weser riverbank between Achim and Verden, as well as on sandy soils in the Weser-Aller floodplain. The loss of localities in the past hundred years is evident from records documented in herbarium specimens, literature and actual findings. The habitats of Corrigiola litoralis can be classified into three types: 1) riverbanks 2) sandy soils in heathland areas and 3) gravel ground at railway sidings and industrial areas. They can be characterised as open pioneer habitats with mineral nonbasic soil and varying humidity. At the riverbank of the Weser Corrigiola litoralis is associated with Chenopodium rubrum, C. glaucum, Atriplex prostrata and Polygonum lapathifolium ssp. danubiale. This species composition, together with Xanthium albinum at the Weser, can be classified into the association Polygono brittingeri-Chenopodion rubri

Crop wild relatives in plant species conservation

Die „Wildpflanzen für Ernährung und Landwirtschaft“ (WEL) umfassen mit 2471 Arten 67,9 % der in Deutschland etablierten Gefäßpflanzen (ohne Neophyten), 11,3 % der Gefäßpflanzen werden als prioritäre WEL-Arten eingestuft. 25,7 % der WEL-Arten sind nach der aktuellen Roten Liste Deutschlands bestandsgefährdet. Für die weltweite Erhaltung von 453 der WEL-Arten hat Deutschland eine hohe Verantwortlichkeit. Das WEL-Konzept bietet neben der Gefährdung und der Verantwortlichkeit ein weiteres Kriterium für Priorisierungen im Artenschutz.With 2471 species, crop wild relatives (CWR) comprise 67.9% of the vascular plants established in Germany (excluding neophytes), 11.3% of the vascular plants are classified as priority CWR species. According to the Red List of Germany, 25.7% of CWR species are endangered. Germany has a high responsibility for the worldwide conservation of 453 WEL species. The WEL concept offers a further criterion for prioritization in species conservation in addition to the criteria of endangering and responsibility

Crassula tillaea (Crassulaceae) auf Norderney : Ausbreitung und Habitate einer (noch) seltenen Art an der Nordseeküste

The Mossy Stonecrop (Crassula Tillaea, Crassulaceae), a very rare species in Germany, was found for the first time on the East Frisian Wadden Sea Island of Norderney in 2017. The massive presence of the species on Norderney is discussed in relation with the current spread of the species and the colonization of new habitats

Cactaceae at Caryophyllales.org- A dynamic online species-level taxonomic backbone for the family

This data paper presents a largely phylogeny-based online taxonomic backbone for the Cactaceae compiled from literature and online sources using the tools of the EDIT Platform for Cybertaxonomy. The data will form a contribution of the Caryophyllales Network for the World Flora Online and serve as the base for further integration of research results from the systematic research community. The final aim is to treat all effectively published scientific names in the family. The checklist includes 150 accepted genera, 1851 accepted species, 91 hybrids, 746 infraspecific taxa (458 heterotypic, 288 with autonyms), 17,932 synonyms of accepted taxa, 16 definitely excluded names, 389 names of uncertain application, 672 unresolved names and 454 names belonging to (probably artificial) named hybrids, totalling 22,275 names. The process of compiling this database is described and further editorial rules for the compilation of the taxonomic backbone for the Caryophyllales Network are proposed. A checklist depicting the current state of the taxonomic backbone is provided as supplemental material. All results are also available online on the website of the Caryophyllales Network and will be constantly updated and expanded in the future.

Assessing the national red lists of European vascular plants: Disparities and implications

The diversity of vascular plant taxa in Europe is threatened. National red lists are valuable biodiversity conservation tools that provide us with information on the proximity of a taxon to extinction. However, there are still differences in the methods and implementation of these assessments across European countries, indicating gaps in conservation efforts at national and regional levels. To address these disparities, we conducted a study in which we compiled data from the most recent national red lists of vascular plants in European countries, including some countries from the eastern part of the Mediterranean biodiversity hotspot. Our results confirm concerns that the conservation status of European vascular flora is not fully mapped. We also found that this knowledge is not evenly distributed across European regions. There were differences in the availability of red lists, the regularity of updates, and the implementation of assessment methods. Countries that assessed their entire flora had a higher proportion of threatened taxa than countries that assessed only a portion of the flora. This highlights the risk of overlooking the conservation status of less known taxa when assessments are limited to specific taxa. Financial capacity was found to be a critical factor influencing the extent of these shortcomings. Our study has shown that countries that assess their entire flora have, on average, higher national spending on environmental protection within their overall economies. This information is critical for developing effective biodiversity conservation strategies across Europe and for addressing the threats faced by vascular plants in the region

An amaizing species of Hildewintera (Cactaceae) characters and systematic position

A recientely described second species of Hildewintera, H. colademonomis , is critically analized. A detailed description is given, and the systematic position and nomencature of the species are discussed. Bout species of Hildewintera are mainly distinguished from Cleistocactus by the double corolla, the difference sculpturing of the seed-testa and the pendulous stems with spines directed donwards. H. colademononis is characterized by a flower woth an axial spur, a character newer previously reported for the cactaceae. Notes onclimate, affinities, nomenclature and taxonomy are also presented.Fil: Kiesling, Roberto. Consejo Nacional de Investigaciones Científicas y Técnicas.

The study of cactus evolution: The pre-DNA era

We provide a short history of the development of phylogenetic concepts for the cactus family in the pre-molecular (here meaning pre-DNA) era, beginning from the creation of the first artificial classification systems, over to natural systems, and on to the progress made in the Post-Darwinian era. Although several authors have presented their ideas on the evolution of Cactaceae, it was the botanists Alwin Berger and Franz Buxbaum who made the most essential contributions towards a cactus phylogeny during the 20th century. In the second half of that century, new techniques and detailed studies (phytochemistry, anatomy, SEM) helped formulate new concepts or revised established concepts about the evolution of cacti.Fil: Metzing, Detlev.
