Fish, amphibian and reptilian faunas from latest Oligocene to middle Miocene localities from Central Turkey

Vasilyan, Davit ; Roček, Zbyněk ; Ayvazyan, Anna ; Claessens, Leon

In: Palaeobiodiversity and Palaeoenvironments, 2019, vol. 99, no. 4, p. 723–757

In this paper, we describe ectothermic vertebrate assemblages from the Kargı 1, Kargı 2, Kargı 3, Harami1, Harami 3, Hancılı, Keseköy, Çandır and Bağiçi localities in Turkey. The ages of these localities range from the latest Oligocene to the middle Miocene. The preserved non-mammalian fauna of the studied localities includes fishes (Luciobarbus sp., Barbus sp., Luciobarbus vel...

Litter decomposition driven by soil fauna, plant diversity and soil management in urban gardens

Tresch, Simon ; Frey, David ; Le Bayon, Renée-Claire ; Zanettac, Andrea ; Rasche, Frank ; Fliessbach, Andreas ; Moretti, Marco

In: Science of The Total Environment, 2019, vol. 658, p. 1614–1629

In the face of growing urban densification, green spaces in cities, such as gardens, are increasingly important for biodiversity and ecosystem services. However, the influences of urban green space management on biodiversity and ecosystem functioning (BEF) relationships is poorly understood. We investigated the relationship between soil fauna and litter decomposition in 170 urban garden sites...

Biochronological and palaeobiogeographical significance of the earliest Miocene mammal fauna from Northern Vietnam

Antoine, Pierre-Olivier ; Made, Jan van der ; Métais, Grégoire ; Phuc, Laq The ; Quan, Quý Tr??ng ; Schneider, Simon ; Tran, Dang Ngoc ; Vasilyan, Davit ; Viet, Luong The ; Böhme, Madelaine

In: Palaeobiodiversity and Palaeoenvironments, 2018, vol. 98, no. 2, p. 287–313

Current scientific knowledge of Tertiary fossils from south of the Ailao Shan-Red River shear zone is extremely poor, in sharp contrast with the situation nowadays, as the area of Laos and Vietnam is regarded as a global hotspot of biodiversity. In this context, the few localities that yielded fossil assemblages are of first importance for the understanding of Cenozoic palaeobiogeography and...

Evolutionary origin of synapses and neurons – Bridging the gap

Burkhardt, Pawel ; Sprecher, Simon G.

In: BioEssays, 2017/39/10/n/a-n/a

The evolutionary origin of synapses and neurons is an enigmatic subject that inspires much debate. Non-bilaterian metazoans, both with and without neurons and their closest relatives already contain many components of the molecular toolkits for synapse functions. The origin of these components and their assembly into ancient synaptic signaling machineries are particularly important in light...

Fossil lizards and snakes from Ano Metochi – a diverse squamate fauna from the latest Miocene of northern Greece

Georgalis, Georgios L. ; Villa, Andrea ; Delfino, Massimo

In: Historical Biology, 2017, vol. 29, no. 6, p. 730–742

We here describe a new squamate fauna from the late Miocene (Messinian, MN 13) of Ano Metochi, northern Greece. The lizard fauna of Ano Metochi is here shown to be rather diverse, consisting of lacertids, anguids, and potential cordylids, while snakes are also abundant, consisting of scolecophidians, natricines and at least two different colubrines. If our identification is correct, the Ano...

Inference of evolutionary jumps in large phylogenies using Lévy processes

Duchen, Pablo ; Leuenberger, Christoph ; Szilágyi, Sándor M. ; Harmon, Luke ; Eastman, Jonathan ; Schweizer, Manuel ; Wegmann, Daniel

In: Systematic Biology, 2017, p. -

Although it is now widely accepted that the rate of phenotypic evolution may not necessarily be constant across large phylogenies, the frequency and phylogenetic position of periods of rapid evolution remain unclear. In his highly influential view of evolution, G. G. Simpson supposed that such evolutionary jumps occur when organisms transition into so-called new adaptive zones, for instance...

Historical and contemporary determinants of global phylogenetic structure in tropical reef fish faunas

Leprieur, Fabien ; Colosio, Simona ; Descombes, Patrice ; Parravicini, Valeriano ; Kulbicki, Michel ; Cowman, Peter F. ; Bellwood, David R. ; Mouillot, David ; Pellissier, Loïc

In: Ecography, 2016, vol. 39, no. 9, p. 825–835

Identifying the main determinants of tropical marine biodiversity is essential for devising appropriate conservation measures mitigating the ongoing degradation of coral reef habitats. Based on a gridded distribution database and phylogenetic information, we compared the phylogenetic structure of assemblages for three tropical reef fish families (Labridae: wrasses, Pomacentridae: damselfishes...
