Mammalian grazing induces changes in vegetation properties in grasslands, which can affect a wide variety of other animals including many arthropods. However, the impacts may depend on the type and body size of these mammals. Furthermore, how mammals influence functional trait syndromes of arthropod communities is not well known. We progressively excluded large (e.g. red deer, chamois),...

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

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...

Palaeoecology of Sphagnum riparium (Ångström) in Northern Hemisphere peatlands : Implications for peatland conservation and palaeoecological research

Gałka, Mariusz ; Galloway, Jennifer M ; Lemonis, Natalie ; Mazei, Yuri A ; Mitchell, Edward A.D ; Morse, Peter D ; Patterson, Timothy R ; Tsyganov, Andrey N ; Wolfe, Stephen A ; Swindles, Graeme T

In: Review of Palaeobotany and Palynology, 2018, vol. 254, p. 1-7

Sphagnum riparium (Ångström) is a rare constituent of modern peatland plant communities and is also very rarely found as a subfossil in peat archives. We present new data on the occurrence of Sphagnum riparium macrofossils in three Northern Hemisphere peatlands from Yellowknife (NWCanada), Abisko (N Sweden), and the Northern Ural Mountains (NWRussia). Sphagnum riparium...

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...
