Scale-Dependent Habitat Nestedness and Its Implications for Anuran Conservation in the Chengdu Region: A Multi-Extent Analysis

open access: yesAnimals
Nestedness in community ecology predicts that species in a species-poor site should be a subset of species of a species-rich site. A variety of ecological mechanisms have been offered to explain community nestedness; however, few studies have ...

Beta diversity of aquatic insects (Ephemeroptera, Plecoptera and Trichoptera) across stream microhabitats [PDF]

open access: yesActa Limnologica Brasiliensia
: Aim We evaluated how the combination of environmental characteristics affects the beta diversity of the EPT (Ephemeroptera, Plecoptera and Trichoptera) community across stream microhabitats. Methods The samples were collected in 12 streams around the

Forest type influence on Heliconia‐dipteran interaction networks

open access: yesInsect Conservation and Diversity, EarlyView.
Responses to forest type depended on the developmental stage of dipterans. Bract traits and forest type influenced larval abundance, but forest type had no impact on adult alpha and beta diversity. Heliconia‐dipteran interaction networks showed a nested pattern for both forest types.

Diversity of Bird Communities in Tea (Camellia sinensis) Plantations in Fujian Province, South-Eastern China

open access: yesDiversity, 2020
Habitat conversion in mountain areas threatens their biodiversity. The effect on biodiversity of creating a mountain landscape with a network of forest fragments and a cultivated habitat matrix is poorly documented in China.

Seasonal dynamics in terrestrial insect communities after the impact of the Brumadinho tailings dam disaster

open access: yesInsect Conservation and Diversity, EarlyView.
Despite severe habitat loss, insect species richness, seasonal fluctuations in richness and temporal β‐diversity did not differ significantly among forests adjacent to the mudflow and reference sites. We found higher wet‐season species richness for ants, bees, butterflies and dung beetles, while termites showed no seasonal change; β‐diversity was ...

Taxonomic nestedness based on guilds? Bird assemblages of the Jardines de la Reina National Park, Cuba, as study case

open access: yesAnimal Biodiversity and Conservation, 2020
Nestedness is a widely known structuring model in insular and fragmented biotas that has often been assessed, but most studies to date have used a taxonomic approach.

Regional Community Building in Hard Times: Communal and Functional Filtering at EU Borders During the COVID‐19 Pandemic

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract Pandemics are times of closure. States typically restrict the entry of persons to protect their national communities from external health hazards. In this regard, the COVID‐19 pandemic presented the European Union (EU) with a severe challenge. We ask to what extent the border policies of EU member states during the pandemic supported regional ...

The theory of island biogeography and the stability of oceanic reef fish communities

open access: yesJournal of Fish Biology, EarlyView.
Abstract Reef fish assemblages on oceanic islands offer valuable insights into ecological and evolutionary processes, yet their temporal dynamics remain poorly understood. This study evaluates the theory of island biogeography (TIB) with long‐term ecological monitoring to assess how island area, isolation from nearest reef and distance from mainland ...

The Babe Ruth Algorithm: a fast, unbiased procedure to randomize presence-absence data matrices with fixed row and column totals

open access: yes, 2014
A well-known problem in numerical ecology is how to recombine presence-absence matrices without altering row and column totals. A few solutions have been proposed, but all of them present some issues in terms of statistical robustness (i.e.

Strategies for Legitimizing Regeneration in Supply Chain Fields

open access: yesJournal of Supply Chain Management, EarlyView.
ABSTRACT In view of escalating environmental degradation, regenerative business has been proposed to restore social–ecological systems. However, as regeneration fundamentally departs from mainstream approaches and lacks commonly accepted standards, it suffers from a liability of newness that hampers its broader legitimation and adoption.
