Annotated checklist of bats (Mammalia: Chiroptera) of Mount Cameroon, southwestern Cameroon
Zoosystema 42 (24)
Mount Cameroon is a priority area for global biodiversity conservation, considering its high species richness and endemism across many taxa. As of yet, its Chiroptera fauna is still poorly known. Thus this paper aims to provide an updated checklist of the Chiroptera fauna of Mount Cameroon based on our own field data, previously published data and data from museum collections. Details on published references and conservation statuses are also provided for each species. During our field surveys (2016-2018), 613 individuals and 21 species were recorded. Among them three species are new to the area: Mops (Xiphonycteris) nanulus J. A.
Nouvelle étude paléoenvironnementale de la « Forêt de Quintefeuille » d’après les cortèges malacologiques holocènes : du passé à l’actuel (Graye-sur-mer, Calvados, Normandie)
Naturae 2020 (7)
Along the Calvados coast, peat deposit outcrops, rich in Holocene land-snails, represent a potential to reconstruct the evolution of the past environments, which are directly linked to the rise of sea-level. Dating and malacological investigation on the sequence of Graye-sur-mer (Calvados, Normandy) has shown a re-established palaeoenvironmental story between the middle Holocene end and the late Holocene begining. The malacological succession has been divided into three malacozones corresponding to three steps of an environmental evolution between 5500 and 3500 year cal. BP, from a swampy forest to a marsh that opens gradually. Maritime influence are noticed from 4000 years cal. BP.
Tropical African Cantharellus Adans.: Fr. (Hydnaceae, Cantharellales) with lilac-purplish tinges revisited
Cryptogamie, Mycologie 41 (10)
The authors discuss several African Cantharellus Adans.: Fr. species with lilac-purplish tinges on the pileus or stipe surface collected in the Central African rain forest or West African gallery forests. The morphology of C. longisporus Heinem. is discussed on the basis of new Central African collections and found profoundly different from two previously described subspecies from Madagascar which are here recombined as C. littoralis (Buyck & Randrianjohany) Buyck, comb. et stat. nov., and C. isaloensis (Buyck & Eyssartier) Buyck, comb. et stat. nov. Cantharellus xanthocyaneus Ndolo Ebika & Buyck, sp. nov., a new look-alike of C. cyanoxanthus R.Heim ex Heinem.
Gender expression in Sedum praealtum A. DC. (Crassulaceae) in Central Veracruz, Mexico
Adansonia 42 (13)
Inflorescence type and design determine the position of reproductive meristems and sequence of flowers opening. I examined the gender expression over two entire flowering seasons in Sedum praealtum A. DC. (Crassulaceae) in Central Veracruz, Mexico. Specifically, I studied the floral longevity, sexual-phase duration, flower opening within an inflorescence and sex ratio in the species. I observed that the 8-days flower initiated in male-phase and then switched to female-phase. An extended time of pollen presentation by gradual anthers dehiscence caused an incomplete protandry in the species. The basal-positioned floral buds reached anthesis sooner than the distal-positioned floral buds, resembling an acropetal flowering sequence.
Amphibians and reptiles from the Neogene of Afghanistan
Geodiversitas 42 (22)
Amphibians and reptiles are decribed for the first time from the Cenozoic of Afghanistan. They originate from four Neogene localities. Sherullah 9 (late Miocene) yielded anuran amphibians (? Alytidae Fitzinger, 1843 (? Discoglossinae Günther, 1858), “Ranidae” Batsch, 1796 and another, indeterminate family), one chelonian, the terrestrial testudinine Agrionemys Khozatsky & Młynarski, 1966, which is compared to a Maragheh fossil specimen, and the genus still being present in the Kabul area; one indeterminate lizard, snakes (Colubridae Oppel, 1811 s.l. and two distinct snakes that pertain to either the Colubridae s.l. or Elapidae Boie, 1827). The faunas of the three other localities are very poor. Molayan (late Miocene) produced only one lizard (Varanus sp.
Genetic affinities and biogeography of putative Levantine-endemic seaweed Treptacantha rayssiae (Ramon) M.Mulas, J.Neiva & Á.Israel, comb. nov. (Phaeophyceae)
Cryptogamie, Algologie 41 (10)
Cystoseira sensu lato (Ochrophyta) forests are important habitat formers in the Mediterranean Sea, but they have mostly been studied in the western basin where many species are under decline. In the eastern basin, where fewer species occur, Cystoseira rayssiae Ramon was described in the year 2000 as an endemic species based on morphological characteristics from herbaria samples collected on the Israeli coast. No further investigations have been conducted on this peculiar species since, but recently it has been recorded in contiguous Lebanon and outside the Mediterranean.
Structural and histochemical characterization of the osmophores in corollas of Asteraceae (tribes Onoserideae and Famatinantheae)
Adansonia 42 (12)
Osmophores are engaged in scent production and differ from other secretory structures by their product, site, duration, and anatomical structure. Whereas osmophores have been well-documented in flowers of several families, they are barely mentioned in the Asteraceae. The aims of this study are to: 1) determine the occurrence of osmophores in corollas of 39 species of the tribe Onoserideae and the only species of Famatinantheae with histochemical methods; and 2) analyze the morphology and structure of osmophores in these groups. Histochemical and histological techniques revealed osmophores in the marginal and in the central corollas of Famatinanthus Ariza & S.E. Freire and Plazia Ruiz & Pav. at the apex and margin of the corolla lobes, and at the sinuses.
La classification des abeilles, de l’Antiquité au début de l’ère moderne
Anthropozoologica 55 (13)
This paper aims to analyse the history of the classification of bees, taking into consideration some important ancient, medieval and Renaissance texts. With regards to Antiquity, it will address specifically Aristotle’s Historia animalium, Pliny the Elder’s Naturalis Historia and Virgil’s Georgica. In the Middle Ages Arabic sources added new material to the history of classification, such as Avicenna’s De animalibus. Medieval encyclopaedism represents a complex phenomenon that shows a progressive idea of direct observations together with the collection of many sources. In this paper, two medieval philosophers and encyclopaedists will be taken into consideration, Thomas of Cantimpré, and Albert the Great.
Ostracods from the ‘Raibl Beds’ (Carnian, Late Triassic) of Belca section in Karavanke Mountains, northwestern Slovenia
Geodiversitas 42 (21)
The taxonomy of marine ostracod assemblages from Belca section in the Karavanke Mountains, northwestern Slovenia, is discussed, adding to the scientific understanding of marine ostracods during the Carnian stage, Late Triassic. In Belca, the ostracod assemblages include 39 species, among which two are newly described: Dicerobairdia buseri Forel, n. sp. and Pontocypris? karavankensis Forel, n. sp. The recovery of abundant juvenile and adult specimens facilitated the illustration and discussion of the ontogenetic series of several typically Triassic species including Renngartenella sanctaecrucis Kristan-Tollmann in Kristan-Tollmann & Hamedani, 1973, Leviella bogschi Kozur, 1972 and Leviella veghae Kozur, 1972.
Quelle est la véritable surface du domaine vital des Tortues d’Hermann (Testudo hermanni Gmelin, 1789) ? Implications pour la conservation
Naturae 2020 (6)
Accurate evaluation of animal home range is crucial for field managers. It provides key information to determine the surface of areas that require protection and to limit population fragmentation. Home ranges (MCP) were obtained in 165 Hermann tortoises radio-tracked across the whole activity season in nine populations of continental France. Our study shows that mean home range was considerably larger compared to previous estimates: 9ha (median 5.2ha) versus 2ha. This strong difference is explained by the small sample sizes collected during short time periods in previous studies. Our intensive monitoring during 10 years provides more realistic estimates. In agreement with the literature, we observed wide inter-individual variations (0.6ha to 95.0ha).
A new terrestrial species of Colura (Marchantiophyta: Lejeuneaceae) at tropical high elevations (Boyacá, Colombia)
Cryptogamie, Bryologie 41 (12)
A new terrestrial species of Colura (Dumort.) Dumort., from high elevations in the northern tropical Andes is described. The species differs from other members of the genus in the section Oidocorys Jovet-Ast ex Grolle on its unique oversized lobule and reduced lobe, and the smooth surface of the leaf cells. An identification key is provided for northern South America. Colura stotleri sp. nov., described here, is found at a single mountain top at 4700 m a.s.l. on peaty soil, with a lack of suitable habitats at higher elevations highlighting the threats posed by climate change on the conservation of mountain flora.
New information on the anatomy and histology of Gracilisuchus stipanicicorum (Archosauria: Pseudosuchia) from the Chañares Formation (early Carnian), Argentina
Comptes Rendus Palevol 19 (3)
Gracilisuchus stipanicicorum Romer, 1972 is a basal suchian from the Late Triassic Chañares Formation (Argentina), nested in the recently erected Gracilisuchidae, along with Turfanosuchus dabanensis Young, 1973 and Yonghesuchus sangbiensis Wu et al., 2001 from China. The six known specimens of Gracilisuchus Romer, 1972 preserve most of the skeleton, lacking only most of the shoulder girdle and forelimb. Our latest fieldwork has recovered two specimens that preserve previously unknown elements, including the humerus, radius, and ulna, as well as the femur, presacral vertebrae, and paramedian osteoderms. The femur and osteoderms were histologically sectioned, which has never been done for Gracilisuchidae.
