Kontrolētas dedzināšanas ietekme uz augsnes bruņērču (Acari:Oribatida) sugu sabiedrībām priežu mētrājā, aizsargājamo ainavu apvidū "Ādaži"
2018
Bruņērces līdz šim ir maz izmantotas sukcesiju pētījumos un zināšanas par augsnes faunas un bruņērču atbildes reakcijām uz dažādiem traucējumiem ir ierobežotas, taču to relatīvi lēnais dzīves cikls un plašā izplatība tās padara par efektīviem ilgtermiņa bioindikatoriem, kas var liecināt par degšanas ietekmes smagumu. Darba mērķis ir noskaidrot kontrolētas dedzināšanas ietekmi uz augsnes bruņērču sabiedrībām, zemsedzi un augsnes parametriem priežu mētrājā. Augsnes paraugi ievākti pirms un 16 dienas pēc kontrolētas dedzināšanas. Pēc degšanas bruņērču indivīdu skaits samazinājies par 93% un sugu skaits par 77%. Izmaiņas ietekmē degšanas ietekmes smagums. Pēc traucējuma eudominējošs taksons ir …
The genus Galumna in Nepalese oribatid mite fauna, with notes on systematic placement of some species (Acari, Oribatida, Galumnidae)
2014
The oribatid mite genus Galumna (Oribatida, Galumnidae) is recorded for the first time in Nepal. A new species, Galumna tetraporosa sp. n., is described from soil of secondary mixed broadleaved forest. It is most similar morphologically to G. tokyoensis Aoki, 1966 and G. valida Aoki, 1994, however, it differs from both by the absence of interlamellar setae and the presence of two pairs of notogastral porose areas Aa. Galumna granalata Aoki, 1984 is redescribed on the basis of specimens from Nepal. Galumna floridae (Jacot, 1929) and G. hexagona Balogh, 1960 are transferred to the genus Notogalumna; G. mauritii Mahunka, 1978 is transferred to the genus Dimidiogalumna.
Ladinian carbonates of the Cabo Cope Unit (Betic Cordillera, SE Spain): a tethys-maláguide palaeogeographic gateway.

Working to the conservation and good use of the Devonian palaeontological heritage in Floresta, Boyacá (Colombia): a review of teaching case studies …
2019
The Floresta Massif, located in the Eastern Cordillera of Colombia, has a diverse and precious natural heritage. It is one of the areas that contains an exceptional palaeontological heritage of the Middle Devonian not only of Colombia, but also of South America. This heritage is represented by fossil specimens of marine fauna and terrestrial flora (correlated with North America and Europe) of the Floresta and Cuche Formations, respectively. Since 2004, actions made by several academic and research institutions, community and local government have introduced schoolchildren, teenagers and University students to art and science, and have promoted the conservation of palaeontological heritage a…
New Miocene locality in Turkey with evidence on the origin of Ramapithecus and Sivapithecus.
1977
Collections in early Middle Miocene deposits at Pasalar in Turkey have yielded a very rich fauna. Included in this are two hominoid species referred here to Sivapithecus darwini (Abel) 1902 and Ramapithecus wickeri (Leakey) 1962. These are both more primitive morphologically and earlier in time than other species of these genera, and they provide evidence that Sivapithecus and Ramapithecus are closely related and that their early diversification may have occurred not in Africa but in Eurasia.
First Early Pliocene micromammal faunas from Venta del Moro (Cabriel Basin, Spain) : new data on the Messinian dispersal of Debruijnimys
2021
The localities of La Bullana 3 and LA Bullana 2B (Valencia, E Spain) have yielded remains of Apodemusgorafensis, Paraethomys aff. abaigari, Stephanomys dubari, Apocricetus barrierei, Sciuridae indet. and Asoriculus cf. gibberodon the former, and Apodemusgorafensis, Paraethomys aff. abaigari, Stephanomys dubari, Apocricetus barrierei, Sciuridae indet., Asoriculus cf. gibberodon, Castillomysgracilis, Occitanomysbrailloni, Occitanomys sp., Paraethomys meini, Ruscinomys sp., Eliomys intermedius, Debruijnimys cf. julii and Atlantoxerussp. the latter. Based on the study of these micromammal assemblages, we propose an Early Pliocene age (MN14) for both sites. The pres-ence a gerbilid related to De…
New data on the Lower Devonian chondrichthyan fauna from Celtiberia (Spain)
2010
Lower Devonian microvertebrate remains from Spain, including localities in Celtiberia and Cantabrian Mountains, have been extensively studied during recent decades (e.g., Mader, 1986; Wang, 1993; ...
Données nouvelles sur Euaspidoceras ferrugineum Jeannet, Ammonitina (Aspidoceratidae) du Callovien supérieur
1998
Abstract A section at the top of Upper Callovian deposits at Louesme (district of Montigny-sur-Aube, Cote-d'Or, France) reveals an unbroken series of strata between the top of the Athleta zone and the base of the Lamberti zone (Upper Callovian). A few specimens of Aspidoceratinae, collected with primitive Quenstedtoceras, are refered to Euaspidoceras ferrugineum Jeannet (1951) . The characters of this species, which was created for individuals collected from the Herznach Mine (Northern Switzerland), are poorly defined from the Swiss material and little is known for this stratigraphic extent. The new find provides information about the ontogeny and the stratigraphic extent of Euaspidoceras f…
A Biochronologic Subdivison of the European Paleogene Based on Mammals — Report on Results of the Paleogene Symposium Held in Mainz in February 1987
1990
In February 1987 the paleontologists working on European mammalian faunas of the Paleogene convened in Mainz to establish a mammal chronology for this time period. The results were edited by the author of this report at the end of the same year (Schmidt-Kittler, 1987). The biochronological subdivision agreed upon in this symposium corresponds to the general conditions met in the European continental Tertiary. Therefore, it is consistent with the concept of subdivision used for the Neogene mammal chronology of Europe elaborated in an earlier meeting in Munich (Fahlbusch, 1976).
Early Aptian corals from Peñascal (Bilbao, N Spain)
2020
From two horizons in the lower Aptian Peñascal limestone Formation south of Bilbao 22 coral species are reported. The corals belong to the scleractinian families Actinastraeidae, Eugyridae, Haplaraeidae, Latomeandridae, and Solenocoeniidae, and the octocorallian family Helioporidae. The stratigraphic distribution of the species lies between the Berriasian to Cenomanian, but most species have a distribution between the Barremian and Albian. The faunas show most palaeobiogeographical relationship to faunas from the Hauterivian to Albian of the European Boreal, the Western Atlantic and the Western Tethys.
