High-elevation insectivorous birds are currently confronted with the reality of a changing climate, land use shifts, and the decline of many prey groups. The diet dynamics among many imperiled animals in this group are still unresolved. [...]

15 p, 1.6 MB Interaction strength in plant-pollinator networks : Are we using the right measure? / Novella-Fernandez, Roberto (University of Southampton. School of Biological Sciences (UK)) ; Rodrigo Domínguez, Anselm (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Arnan, Xavier (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Bosch, Jordi, 1961- (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Understanding how ecological networks are assembled is important because network structure reflects ecosystem functioning and stability. Quantitative network analysis incorporates measures of interaction strength as an estimate of the magnitude of the effect of interaction partners on one another. [...]

13 p, 798.2 KB Nematode distributions as spatial null models for macroinvertebrate species richness across environmental gradients : a case from mountain lakes / Mendoza, Guillermo de (Centre d'Estudis Avançats de Blanes) ; Traunspurger, Walter (Bielefeld Universität. Department of Animal Ecology) ; Palomo González, Alejandro (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Catalán, Jordi (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Nematode species are widely tolerant of environmental conditions and disperse passively. Therefore, the species richness distribution in this group might largely depend on the topological distribution of the habitats and main aerial and aquatic dispersal pathways connecting them. [...]

12 p, 217.1 KB A new fossil ichneumon wasp from the Lowermost Eocene amber of Paris Basin (France), with a checklist of fossil Ichneumonoidea s.l. (Insecta : Hymenoptera : Ichneumonidae : Metopiinae) / Menier, J.-J. (Muséum National d'Histoire Naturelle) ; Nel, A. (Muséum National d'Histoire Naturelle) ; Waller, A. (Muséum National d'Histoire Naturelle) ; Ploëg, G. de (Muséum National d'Histoire Naturelle)
We describe a new fossil genus and species Palaeometopius eocenicus of Ichneumonidae Metopiinae (Insecta: Hymenoptera), from the Lowermost Eocene amber of the Paris Basin. A list of the described fossil Ichneumonidae is proposed.

8 p, 678.2 KB A new bethylid wasp from the Lowermost Eocene amber of France (Hymenoptera : Bethylidae : Bethylinae) / Ploëg, G. de (Muséum National d'Histoire Naturelle (París, França)) ; Nel, A. (Muséum National d'Histoire Naturelle (París, França))
Protobethylus eocenicus, new genus and species of Bethylidae: Bethylinae, is described from the Lowermost Eocene amber of the Paris Basin (France). Anew phylogenetic analysis of the bethyline genera is proposed. [...]

8 p, 264.5 KB An aulacid wasp in the Lowermost Eocene amber from the Paris Basin (Hymenoptera : Aulacidae) / Nel, A. (Muséum National d'Histoire Naturelle (París, França)) ; Waller, A. (Muséum National d'Histoire Naturelle (París, França)) ; Ploëg, G. de (Muséum National d'Histoire Naturelle (París, França))
Aulacus eocenicus n. sp. is described from the Lowermost Eocene amber of the Paris basin. It is apparently similar to the Australian modern (sub)-genus Micraulacinus KIEFFER 1910. We propose a commented list of the fossil species that have been attributed to the Aulacidae. [...]

A new genus and two new species of bee flies are described from the Lowermost Eocene amber of the Paris basin: Paradolichomyia eocenica n. gen, n. sp. (Bombyliidae: Toxophorinae) and Proplatypygus matilei n. [...]

5 p, 201.3 KB The oldest palm bug in the Lowermost Eocene amber of the Paris Basin (Heteroptera : Cimicomorpha : Thaumastocoridae) / Nel, A. (Muséum National d'Histoire Naturelle (París, França)) ; Waller, A. (Muséum National d'Histoire Naturelle (París, França)) ; Ploëg, G. de (Muséum National d'Histoire Naturelle (París, França))
The oldest fossil Thaumastocoridae, Protodoris minusculus n. gen. , n. sp. is described from the Lowermost Eocene amber of Paris basin (France). Its phylogenetic affinities are discussed. This discovery indicates the presence of a very warm climate for the Paris basin during the Lowermost Eocene.

(Muséum National d'Histoire Naturelle (París, França)) ; Waller, A. (Muséum National d'Histoire Naturelle (París, França)) ; Ploëg, G. de (Muséum National d'Histoire Naturelle (París, França))
The oldest fossil Piesmatidae, Eopiesma trimerum n. gen. , n. sp. is described from the Lowermost Eocene amber of Paris Basin (France). It is considered as the sister group of all other Piesmatidae. [...]

7 p, 326.3 KB The oldest ant in the Lower Cretaceous amber of Charente-Maritime (SW France) (Insecta : Hymenoptera : Formicidae) / Nel, A. (Muséum National d'Histoire Naturelle (París, França)) ; Perrault, G. ; Perrichot, V. (Géosciences Rennes I) ; Néraudeau, D. (Géosciences Rennes I) ; Centre National de Recherche Scientifique (França)
Gerontoformica cretacica n. gen. , n. sp. , until now the oldest known ant, is described after a putative worker specimen, from the Uppermost Albian amber of France. Although its characters are those of modern ants, it does not fit in any recent ant subfamilies.
