Asterolepis alticristata n. sp. (Antiarchi) from the Upper Devonian (Frasnian) of Nunavut, Canada, and a report on the antiarch diversity of the Fram Formation
Geodiversitas 41 (19)
A large collection of fossils from the NV2K17 locality, Upper Devonian (Frasnian) Fram Formation, Ellesmere Island, Nunavut, Canada, represents at least two species of Asterolepis. The first, Asterolepis alticristata n. sp., is diagnosed by a tall midline crest that rises sharply from the tergal angle of the anterior median dorsal plate, reaches maximum height at around the position of the lateral corners, and then drops to form a low midline crest along the posterior median dorsal plate. The second species is identified as Asterolepis cf. radiata according to an ornament of radiating rows of conjoined tubercles and ridges on the available thoracic plates (anterior median dorsal, posterior median dorsal, and mixilateral).
A review of the genus Macromitrium Brid. (Orthotrichaceae, Bryophyta) in New Caledonia
Cryptogamie, Bryologie 40 (16)
Macromitrium Brid., one of the richest moss genera in New Caledonia, has not so far been revised. In the vicinity, only New Zealand, Australia and Papua New Guinea have benefited from a comprehensive overview of Macromitrium species. A review of the morphological characters of the types, completed by many fresh specimens collected since 2000, enables to clarify the relationship between the 46 taxa inherited from past and present bryological contributions since 1857 and to define five main morphological patterns among the Macromitrium species in New Caledonia. Taxonomic treatment includes synonymies, typifications, descriptions, ecological and geographical features. Eventually 24 taxa are accepted at specific or infraspecific rank.
Cytheroid ostracods (Crustacea) from South Korea, with description of a new species
Zoosystema 41 (22)
Living cytheroid ostracod fauna from South Korea is very poorly known, and so far only 12 species have been reported in the taxonomic literature with detail description. We describe one new species, Xestoleberis hujeongensis n. sp., and report three other cytheroid ostracods: X. setouchiensis Okubo, 1979; X. sagamiensis Okubo, 1976; and Hemicytherura kajiyamai Hanai, 1957 from the east coast of Korea. The new species is most closely related to Xestoleberis hanaii Ishizaki, 1968, a widely distributed and ecologically versatile species. The two species have a very similar carapace shape and soft body parts morphology.
Additions to the bryophyte flora of the Republic of Northern Macedonia
Cryptogamie, Bryologie 40 (15)
The bryophyte flora research in the Republic of Northern Macedonia has been neglected for decades. Here, we report 18 new records, namely two liverworts and 16 moss species for this territory. For each new species presented here, the next information is given: collection data, short notes on distribution in Europe, the Balkan countries and the Mediterranean Region, as well as frequency and IUCN threat categories in the Balkan countries if any. For taxonomically interesting species the peculiarities such as diagnostic morphological characters are explained. With these new records the bryophyte flora of the Republic of Northern Macedonia counts 575 species (one hornwort, 104 liverworts and 470 mosses).
Changes in functional and taxonomic diversity and composition of corticolous lichens in an altitudinal gradient in Colombia
Cryptogamie, Mycologie 40 (6)
The variation of the diversity, composition, functional diversity and species richness of lichen communities along an altitudinal gradient in the Chocó biogeographic region of the department of Valle del Cauca, Colombia, is evaluated basing on 2732 samples belonging to 690 species of corticolous lichens. The dominant families were Graphidaceae, Parmeliaceae, Lobariaceae and Pyrenulaceae. Alpha lichen diversity showed a concave pattern with respect to altitude, and the zones at low and high elevations had greater diversity. Beta diversity and total richness estimated by rarefaction for locality presented a bell-shaped pattern, with a peak at 1600 m. Lichen functional traits strongly changed with the increase of altitude.
Phylogenetic relationships of Nyctereutes Temminck, 1838 (Canidae, Carnivora, Mammalia) from early Pliocene of Çalta, Turkey
Geodiversitas 41 (18)
The locality of Çalta has yielded one of the richest collection of fossil canids belonging to the raccoon dog genus Nyctereutes Temminck, 1838. This locality is situated in central Anatolia and its age is determined as early Pliocene, c. 4 Ma. Ginsburg (1998) studied these canid remains and identified them as N. donnezani, which was previously known from some early Pliocene localities in southern France and Spain. Some later studies questioned this attribution. The present study provides a new description of all available material, housed in collections in Paris, Lyon and Ankara, and a detailed comparison of the cranial and dental characters with other known species of Nyctereutes.
New records for bryophyte flora of Corsica
Cryptogamie, Bryologie 40 (14)
As a result of recent field work, three liverworts (Myriocoleopsis minutissima subsp. minutissima (Sm.) R.L. Zhu, Y. Yu & Pócs, Riccia cavernosa Hoffm. emend. Raddi, Riella notarisii (Mont.) Mont.) and five mosses (Brachytheciastrum dieckei (Röll) Ignatov & Huttunen, Hedwigia striata (Wilson) Bosw., Orthotrichum laevigatum J.E. Zetterst., Tortula schimperi M.J. Cano, O. Werner & J. Guerra, and Zygodon forsteri (Dicks.) Mitt.) were newly recorded for Corsica. The new localities are briefly described. As a result, the bryophyte flora of Corsica now comprises 587 species, among which 424 mosses, 160 liverworts and three hornworts.
Golf: nature-incompatible activity or ecological opportunity?
Naturae 2019 (8)
Considering the necessary ongoing maintenance operations on turf and their characteristic large playing areas, golf courses facilities are known to have an impact on the water resource and the biodiversity. More than 30 000 hectares on the French metropolitan territory are allocated to golf courses. Is it all bad news for the environment? The question of the environmental impacts of golf facilities, like other human activities, must be addressed in a global background of biodiversity erosion. Insofar as an activity responds to a strong social and economic or even societal demand, the idea is not to position oneself “for” or “against” but to guide it so that it has the least impact on the environment. Supporting the golf industry to reduce its environmental impact is a necessity.
The modern ontological natures of the Cairina moschata (Linnaeus, 1758) duck. Cases from Perú, the northern hemisphere, and digital communities
Anthropozoologica 54 (13)
Now a global inhabitant, the Muscovy duck Cairina moschata (Linnaeus, 1758) was domesticated millennia ago by Pre-Columbian indigenous societies of America. Driven increasingly afar by humankind, the expansion of this species is an example of the successful dispersion of an animal known for its adaptability and resilience. This article examines various cases of husbandry, reproduction, and uses of Cairina moschata in the north and central coasts of Perú, Mexico, and North America. This exercise permits us to identify the various ways in which humans approach this versatile, charismatic, and always independent bird raised for its meat, unique behavior, or quality as companion animal or pet.
Unexpected diversity of the genus Collarina Jullien, 1886 (Bryozoa, Cheilostomatida) in the NE Atlantic-Mediterranean region: new species and reappraisal of C. balzaci (Audouin, 1826) and C. fayalensis Harmelin, 1978
Zoosystema 41 (21)The genus Collarina Jullien, 1886 (Cribrilinidae Hincks, 1879) has until now been known from the Atlantic-Mediterranean region as just two species, C. balzaci (Audouin, 1826), synonym of Collarina cribrosa Jullien, 1886, type species of the genus, considered to be widely distributed from the northern British Isles to the SE Mediterranean, and C. fayalensis Harmelin, 1978 from the Macaronesian Isles. Abundant material collected in the Mediterranean and the NE Atlantic, coupled with examination of museum specimens, allowed better definition of the species-specific morphological features in this genus and some generic traits (ooecium formation, avicularia with nested cystids).
Do Dialytrichia mucronata and D. saxicola share the same ecological preferences? A case study in the Rhône Valley (France) and possible application for river incision biomonitoring.
Cryptogamie, Bryologie 40 (13)
Anthropization has led to severe river incision in several parts of Europe. Biomonitoring is of interest to characterize this incision or, conversely, the effectiveness of ecological restoration. Mosses of the upper flood zone are good candidates for such biomonitoring as they are small organisms with limited water-intake ability. Here we studied the Dialytrichia mucronata (Brid.) Broth. - D. saxicola (Lamy) M.J. Cano species pair, both mostly encountered in the upper flood zone; the latter was hypothesized to be more resistant to water stress. We analysed 179 bryosociological relevés in the French Rhône River watershed, distributed along a wide ecological interval.
The scientific expedition of João da Silva Feijó to the Cabo Verde Islands (1783-1796) and the tribulations of his herbarium
Adansonia 41 (12)
João da Silva Feijó (1760-1824), Portuguese naturalist taking part in the “Philosophical Journeys” under the patronage of the Portuguese Crown, led the first scientific expedition devoted exclusively to the study of the Natural History of the Cabo Verde Islands between 1783 and 1796. On behalf of the Royal Museum of Natural History and Botanical Garden of Ajuda in Lisbon, Feijó made the first extensive plant collections (1783-1789) on all of the islands that together with his manuscripts offer a glimpse of the flora of Cabo Verde, as it existed at the end of 18th century. This study provides unique data on the legacy of Feijó’s collections, with details of his expedition through the Cabo Verde Islands.
