Nestedness in forest mammals is dependent on area but not on matrix type and sample size: an analysis on different fragmented landscapes

open access: yesBrazilian Journal of Biology
Nestedness, the pattern in which the species of a species-poor community are a subset of species-rich communities, can provide information regarding species order of extinction, which is vital knowledge for conservation biology.

Underlying factors promoting nestedness of bird assemblages in cays of the Jardines de la Reina archipelago, Cuba [PDF]

open access: yesAnimal Biodiversity and Conservation, 2017
Assessing the factors associated with nestedness patterns is a crucial aspect in studies of community structure. Bird assemblages in the Jardines de la Reina archipelago have a stable nested structure but the underlying influences have not been evaluated.

Brief Pollination Assessment of a Critically Endangered Food-Deceptive Orchid (Cypripedium guttatum) Using a Network Approach

open access: yesPlants, 2022
The translocation of orchids (Orchidaceae) cannot be successful if one is unaware of their effective pollinators and plant–pollinator interactions. Cypripedium guttatum is a generalized food-deceptive orchid, which is highly threatened in the Republic of

Accelerating the prioritisation of plant species with underexplored medicinal potential: The pm4mp (Phylogenetic Methods for Medicinal Plants) R package

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Medicinal plants used in ethnobotanical traditions to treat or prevent diseases have gained renewed interest for their largely untapped potential in drug discovery. In this study, we developed and tested novel methods to prioritise plant species based on their unexplored medicinal potential. By enabling researchers to target the most promising species,

Microenvironments’ Fine-Scale Influence on Amphibian Communities in Chengdu Plain

open access: yesEcosystem Health and Sustainability
In community ecology, a species-poor site’s species should be part of a richer site’s species. This ecological pattern, known as nestedness, is intrinsically related to β diversity, yet their relationship remains insufficiently explored, particularly at ...

Nestedness Maximization in Complex Networks through the Fitness-Complexity Algorithm

open access: yesEntropy, 2018
Nestedness refers to the structural property of complex networks that the neighborhood of a given node is a subset of the neighborhoods of better-connected nodes.

Understanding scaling through history-dependent processes with collapsing sample space [PDF]

open access: yes, 2015
History-dependent processes are ubiquitous in natural and social systems. Many such stochastic processes, especially those that are associated with complex systems, become more constrained as they unfold, meaning that their sample-space, or their set of ...

Inter‐Annual Variation in Alpha and Beta Diversity of Benthic Macroinvertebrate Communities in Agricultural Ditches

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Ditches are essential elements of the agricultural landscape because of their role as habitat or refuge for aquatic species, especially in homogenized and intensively cultivated areas. However, data on the biodiversity associated with agricultural ditches, and its variation over time, are underrepresented in ecological research.

Revealing Beta-diversity patterns of breeding bird and lizard communities on inundated land-bridge islands by separating the turnover and nestedness components.

open access: yesPLoS ONE, 2015
Beta diversity describes changes in species composition among sites in a region and has particular relevance for explaining ecological patterns in fragmented habitats.

On traits matching and the modular organization of food web and occurrence networks

open access: yesJournal of Animal Ecology, EarlyView.
What mechanisms shape ecological networks? In Paraná River piscivores, species traits and abundance scaling promote modular structures. Our findings reveal how communities self‐organize and highlight the conditions needed to sustain them. Abstract Modularity and nestedness have been observed recurrently across different ecological networks, including ...
