Ultrastructure and distribution of kleptoplasts in benthic foraminifera from shallow-water (photic) habitats

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Assimilation, sequestration and maintenance of foreign chloroplasts inside an organism is termed “chloroplast sequestration” or “kleptoplasty”. This phenomenon is known in certain benthic foraminifera, in which such kleptoplasts can be found both intact an ...

Ecohydrological controls on plant diversity in tropical South America

Sara Bonetti

Plant species distribution is dominated by abundance and fluctuations of the available resources. Although diversity patterns along rainfall, latitudinal, and altitudinal gradients have been thoroughly examined, the role of hydrological processes in sustai ...

Contrasting processes drive alpha and beta taxonomic, functional and phylogenetic diversity of orthopteran communities in grasslands

François Gillet, Bertrand Fournier

Taxonomic, functional and phylogenetic diversities can respond differently to biotic and abiotic filters. However, biodiversity management tends to focus on a single index, generally taxonomic diversity, assuming a strong positive correlation among biodive ...

Disturbance-grazer-vegetation interactions maintain habitat diversity in mountain pasture-woodlands

Alexandre Buttler, François Gillet, Alexander Ludwig Johannes Peringer

Low-intensity livestock grazing is a widespread management tool in order to maintain habitat diversity in mountain pasture-woodlands for nature conservation purposes. Historical photographs indicate that forest disturbance significantly contributed to fore ...

Covariations in ecological scaling laws fostered by community dynamics

Andrea Rinaldo, Andrea Giometto, Silvia Zaoli, Amos Maritan

Scaling laws in ecology, intended both as functional relationships among ecologically relevant quantities and the probability distributions that characterize their occurrence, have long attracted the interest of empiricists and theoreticians. Empirical evi ...

SENSITIVITY ANALYSIS OF THE HYDROMORPHOLOGICAL INDEX OF DIVERSITY USING NUMERICAL GENERATED DATA

Anton Schleiss, Severin Stähly, Pierre Bourqui, Christopher Robinson

River restoration has become a priority goal in many countries. The interest in rivers as valuable habitats for floral and faunal diversity and as an ecosystem with important functions has increased. For evaluating the structural changes from a river resto ...

Recent changes in mountain grasslands: a vegetation resampling study

François Gillet

Understanding how land-use changes affect different facets of plant biodiversity in seminatural European grasslands is of particular importance for biodiversity conservation. As conclusions of previous experimental or synchronic observational studies did n ...

Functional responses of multitaxa communities to disturbance and stress gradients in a restored floodplain

Edward Mitchell, François Gillet, Renée-Claire Le Bayon, Bertrand Fournier

Trait-based approaches can reveal the mechanisms through which disturbances or stress impact communities, allowing comparisons of the role of different mechanisms in shaping communities among taxonomic groups. Such information can lead to higher comparabil ...

Experimental evidence for strong stabilizing forces at high functional diversity of aquatic microbial communities

Andrea Rinaldo, Andrea Giometto, Francesco Carrara, Florian Altermatt

Unveiling the mechanisms that promote coexistence in biological communities is a fundamental problem in ecology. Stable coexistence of many species is commonly observed in natural communities. Most of these natural communities, however, are composed of spe ...

Coexistence of specialist and generalist species is shaped by dispersal and environmental factors

Séverine Vuilleumier Varisco

Disentangling the mechanisms mediating the coexistence of habitat specialists and generalists has been a long-standing subject of investigation. However, the roles of species traits and environmental and spatial factors have not been assessed in a unifying ...
