The rare Fissidens jansenii Sérgio & Pursell is reported on plateau de Millevaches, Limousin (France), nearly 1000 km north of the nearest known population. As a result, F. jansenii is known from the Iberian Peninsula and now from western France. An updated distribution map of the species in Europe is provided. The new material is fully described and illustrated and the ecology in France is outlined. Gametophytically, French specimens of F. jansenii do not deviate significantly from Portuguese material and the variability of characters is discussed. In France, on plateau de Millevaches, F. jansenii is relatively frequent but constitutes rather small populations, with a low number of individuals. Sporophytes were regularly encountered and reproduction is most likely to be by spore dispersal. On plateau de Millevaches, F. pusillus (Wilson) Milde shares a comparable habitat but is easily distinguished from F. jansenii. Morphologically similar species occurring in Western Europe and that could potentially be confused with F. jansenii (F. rivularis and F. rufulus Bruch & Schimp.) are compared.

Thallus Surface

Lichen material from the Iberian Peninsula of Melanelia commixta, M. hepatizon and M. sorediella has been studied and compared on the basis of morphology, chemistry, habitat and distribution. The new combination Melanelia sorediella is proposed and Cetraria commixta f. sorediella is lectotypified. Chemotypes I and III have been detected in M. commixta. Melanelia sorediella is characterized mainly by the formation of pycnoisidia and soralia-like structures in the lamina and margins of the thallus and by the absence of pseudocyphellae and apothecia. The pycnoisidium is here described as a combination of isidia-like proliferations of the thallus surface containing pycnidia, carrying algae and acting as vegetative symbiotic propagules. Non detached pycnoisidia grow into lobuli in central parts of the thallus, regenerating it. Pycnoisidia, soralia-like areas and lobuli are formed as a consequence of pycnidia development. Melanelia sorediella is morphologically and chemically close to M. commixta and is currently known from mountains of central and south-west Europe where it grows on acid rocks. In south-western Europe, the meridional limit of the distribution of the three species studied seems to be located in the mountains of the central part of the Iberian Peninsula (Sistema Central Ibérico). Relevant data on the three species are provided and a key is also included.

The spionid polychaete Dipolydora giardi (Mesnil, 1896), originally described as a borer in coralline algae from northern France, was later reported world-wide boring into various shells, sponges and also inhabiting mud tubes on soft bottoms. The reported morphological variability and wide range of habitats suggested that more than one species might be involved. In the present study, D. giardi is redescribed based on some material from northern France sent by F. Mesnil in 1896 to the Zoological Museum, University of Copenhagen, and on new material collected in Italy. The species is characterized by its incised prostomium, caruncle to the end of chaetiger 3, branchiae on the anterior half of the body (usually beginning on chaetiger 10), pygidium with one ventral lobe and two smaller dorsal lobes, and heavy falcate spines of chaetiger 5 with a large lateral tooth on one side and a smaller accessory spur on the other side. Dipolydora trilobata (Radashevsky, 1993) is a closely similar species, but is maintained as distinct. Dipolydora anoculata (Moore, 1907) is probably a valid species and should be removed from the synonymy of D. giardi.

Abstract—Two new diploid species, Aira minoricensis and Aira hercynica, are described and illustrated, along with chromosome counts, risk assessment, distribution and habitat, phenology, and comparisons with morphologically similar species. A comparative table and a key for the species of Aira for the Iberian Peninsula and the Balearic Islands are provided to assist in the identification of these overlooked species, and their relationships to other taxa are discussed.

Genetic management of fragmented populations involves the application of evolutionary genetic theory and knowledge to alleviate problems due to inbreeding and loss of genetic diversity in small population fragments. Populations evolve through the effects of mutation, natural selection, chance (genetic drift) and gene flow (migration). Large outbreeding, sexually reproducing populations typically contain substantial genetic diversity, while small populations typically contain reduced levels. Genetic impacts of small population size on inbreeding, loss of genetic diversity and population differentiation are determined by the genetically effective population size, which is usually much smaller than the number of individuals.

Embolemidae is a cosmopolitan but species-poor group of chrysidoid wasps with a scarce fossil record, despite a long evolutionary history since at least the Early Cretaceous. Here, the new species, Ampulicomorpha quesnoyensis sp. nov., is illustrated and described based on a single female found in Early Eocene amber of Oise (France). The new species is compared with the three other known fossil species of the genus, and a key to all fossil species of Ampulicomorpha is provided. This is the third European fossil species of Ampulicomorpha, which suggests that the genus was once well established in Western Europe while it is more widely distributed in the Eastern Palaearctic region today. A list of all fossil and extant Embolemidae of the world, as well as a map of their geographical distribution map, are provided.

The Cost

Seventy-three years ago pioneer American medievalist Dana Carlton Munro (1911: 504) delivered a paper in Philadelphia to the American Philosophical Society entitled “The Cost of Living in the Twelfth Century.” He threw down the gauntlet by concluding that in this paper an attempt has been made to set forth only a few of the facts, merely to indicate the nature and importance of the problem. Every one of the subjects here discussed is susceptible of elaboration, and needs to be worked out in detail for each country of Western Europe and each period in the twelfth century. The material is voluminous…. This field, as a whole, offers a good opportunity for many monographs, and such work is essential before we can understand the economic history of the century which was most important in the advance of western Europe.This article takes up this challenge with new material on the cost of living in Italy in the twelfth century.

The Battle of Rencesvals is the one of the most dramatic historical event of the entire eighth century, not only in Vasconia but in Western Europe. This monograph examines the battle as more than a single military encounter, but instead as part of a complex military and political conquest that began after the conquest of the Iberian Peninsula in 711 and culminated with the creation of the Kingdom of Pamplona in 824. The battle had major (and largely underappreciated) consequences for the internal structure of the Carolingian Empire. It also enjoyed a remarkable legacy as the topic of one of the oldest European epic poems, La Chanson de Roland. The events that took place in the Pyrenean pass of Rencesvals (Errozabal) on 15 August 778 defined the development of the Carolingian world, and lie at the heart of the early medieval contribution to the later medieval period.

Scorzonera amasiana Hausskn. and Bornm. was described from type specimens collected by J.F.N. Bornmueller in 1889 but it was not collected again until 1993, when it was found near Amasya, Turkey. Populations of S. amasiana were quite small at that limited locations and were vulnerable to human impacts. Therefore, suitable conservation strategies should be developed immediately in order to protect the species from probable extinction. Here, an additional three small populations are reported. Brief history, morphology, habitat and ecology of this endemic species have been discussed. Its current conservation status was reevaluated with respect to the latest IUCN criteria. A key to distinguish it from the other closely related Turkish species is also provided and its distribution map is appended.   Key words: Endangered, Rediscovery, Scorzonera, Turkey DOI = 10.3329/bjb.v36i2.1502 Bangladesh J.
