Biological invasions have steadily increased over recent centuries. However, we still lack a clear expectation about future trends in alien species numbers. In particular, we do not know whether alien species will continue to accumulate in regional floras and faunas, or whether the pace of accumulation will decrease due to the depletion of native source pools. Here, we apply a new model to...

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...

Computational socioeconomics

Gao, Jian ; Zhang, Yi-Cheng ; Zhou, Tao

In: Physics Reports, 2019, vol. 817, p. 1–104

Uncovering the structure of socioeconomic systems and timely estimation of socioeconomic status are significant for economic development. The understanding of socioeconomic processes provides foundations to quantify global economic development, to map regional industrial structure, and to infer individual socioeconomic status. In this review, we will make a brief manifesto about a new ...

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...

A dynamical approach to identify vertices centrality in complex networks

Guo, Long ; Zhang, Wen-Yao ; Luo, Zhong-Jie ; Gao, Fu-Juan ; Zhang, Yi-Cheng

In: Physics Letters A, 2017, vol. 381, no. 48, p. 3972–3977

In this paper, we proposed a dynamical approach to assess vertices centrality according to the synchronization process of the Kuramoto model. In our approach, the vertices dynamical centrality is calculated based on the Difference of vertices Synchronization Abilities (DSA), which are different from traditional centrality measurements that are related to the topological properties. Through...

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...

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...
