Abstract Environmental tracers, including both elemental concentrations and isotope ratios, are widely used to reconstruct the movement patterns of animals throughout landscapes. The methodology involves creating a map that describes the distribution of the environmental tracer across the landscape, an isoscape and then matching the values of the same ...

The emergence of metacommunity theory has provided a framework for studying the spatial structure of biological communities. To unravel the underlying driving mechanisms of macroinvertebrate metacommunity structure and diversity, this paper evaluates ...

Species sorting drives variation of boreal lake and river macrophyte communities [PDF]
Metacommunity paradigms are increasingly studied to explain how environmental control and spatial patterns determine variation in community composition. However, the relative importance of these patterns on biological assemblages among different habitats

Graph tools for analysing trophic assemblies in the isotopic space
Abstract A large amount of information on the trophic assembly of ecosystems is summarized in the isotopic space, and metrics for extracting this information are essential. Here, we show how the characterization of the isotopic space as an isotopic‐network of organisms linked by their trophic similarity significantly expands the isotopic toolbox for ...

Limit theorems for supercritical age-dependent branching processes with neutral immigration [PDF]
We consider a branching process with Poissonian immigration where individuals have inheritable types. At rate theta, new individuals singly enter the total population and start a new population which evolves like a supercritical, homogeneous, binary ...

Interconnectivity and metacommunication
The study of interpersonal communication touches on a range of different disciplines, each with its own focus. This has given rise to an apparent fragmentation in the literature which is manifested in the categorisation of the various components of a communicative act, and even the subdivision of the categories established.

The gut microbiota of Gansu zokor is classified into two enterotypes, which exhibit distinct seasonal and habitat distributions, microbial diversity, and community compositions dominated by different Bacillota‐to‐Bacteroidota ratios. These enterotypes correlate with host body size and are characterized by unique probiotic and pathogenic biomarkers ...

The Metacity: A Conceptual Framework for Integrating Ecology and Urban Design
We introduce the term metacity as a conceptual framework that can be shared by ecologists and designers and applied across the wide variety of urban habitats found around the world.

The roles of trophic interactions, competition and landscape in determining metacommunity structure of a seed-feeding weevil and its parasitoids [PDF]
Community composition is determined by attributes of the environment, individual species, and interactions among species. We studied the distributions of a seed weevil and its parasitoid and hyperparasitoid wasps in a fragmented landscape. The occurrence
