The ghost of nestedness in ecological networks [PDF]

Nature Communications, 2013
Ecologists are fascinated by the prevalence of nestedness in biogeographic and community data, where it is thought to promote biodiversity in mutualistic systems. Traditionally, nestedness has been treated in a binary sense: species and their interactions are either present or absent, neglecting information on abundances and interaction frequencies ...

Seasonal patterns of taxonomic and functional beta diversity in submerged macrophytes at a fine scale

Ecology and Evolution, 2021
Spatiotemporal variation in community composition is of considerable interest in ecology. However, few studies have focused on seasonal variation patterns in taxonomic and functional community composition at the fine scale. As such, we conducted seasonal

The Isomorphic Version of Brualdi’s and Sanderson’s Nestedness [PDF]

Algorithms, 2017
The discrepancy BR for an m × n 0, 1-matrix from Brualdi and Sanderson in 1998 is defined as the minimum number of 1 s that need to be shifted in each row to the left to achieve its Ferrers matrix, i.e., each row consists of consecutive 1 s followed by consecutive 0 s. For ecological bipartite networks, BR describes a nested set of relationships. Since

The Dynamical Hypothesis in Situ: Challenges and Opportunities for a Dynamical Social Approach to Interpersonal Coordination

Topics in Cognitive Science, EarlyView., 2023
Abstract Over the past three decades, Van Gelder's dynamical hypothesis has been instrumental in reconceptualizing the ways in which perception‐action‐cognition unfolds over time and in context. Here, I examine how the dynamical approach has enriched the theoretical understanding of social dynamics within cognitive science, with a particular focus on ...

Elevation Filters Lizard Species Occurrences and Assemblages in Chitwan Annapurna Landscape, Nepal. [PDF]

Ecol Evol
We investigated lizard species richness,assemblage patterns, and environmental drivers along the elevational gradient in the Chitwan Annapurna Landscape during 2018–2019. We recorded 23 lizard species and found that species richness varied significantly and non‐linearly with elevation, peaking at mid elevation. Species turnover dominated beta diversity,

Multidimensional nestedness patterns and underlying processes of bird assemblages in the Zhoushan Archipelago, China

Avian Research
Nestedness is one of the important patterns in island biogeography, community ecology and conservation biology. However, most previous nestedness studies focus on the taxonomic dimension while neglecting the functional and phylogenetic processes in ...

Effects of Dispersal Mode on the Environmental and Spatial Correlates of Nestedness and Species Turnover in Pond Communities [PDF]

, 2017
Advances in metacommunity theory have made a significant contribution to understanding the drivers of variation in biological communities. However, there has been limited empirical research exploring the expression of metacommunity theory for two ...

Nestedness of benthic diatom metacommunity in relation to species niche width and environmental variables in a large near-natural catchment

Frontiers in Ecology and Evolution
Insight into the non-random distribution patterns of species in different regions is a foundational aim of research in community ecology and biogeography.

Downstream Changes in Odonate (Insecta: Odonata) Communities along a Suburban to Urban Gradient: Untangling Natural and Anthropogenic Effects

Insects, 2021
The community structure of lotic odonates (Insecta: Odonata) changes downstream, but it is difficult to untangle natural and anthropogenic causes. We surveyed larvae and adults at 15 sites along the Reedy River in Greenville Co., SC, USA, from sites in ...

Abundant and Rare Bacterial Taxa Structuring Differently in Sediment and Water in Thermokarst Lakes in the Yellow River Source Area, Qinghai-Tibet Plateau

Frontiers in Microbiology, 2022
Thermokarst lakes are forming from permafrost thaw and are severely affected by accelerating climate change. Sediment and water in these lakes are distinct habitats but closely connected. However, our understanding of the differences and linkages between
