Helminth Communities of Common Fish Species in the Coastal Zone off Crimea: Species Composition, Diversity, and Structure

Biology, 2023
In this paper, we analyzed the diversity and structure of helminth communities of 12 common fish species from the coastal zone of Crimea. A total of 53 helminth species were found.

Trapped in the web: network architectures spread coevolution and shape adaptation

Oikos, EarlyView.
Adaptation is critical for biodiversity to persist under global change. Within ecological communities, species often face tradeoffs between adapting to shifting abiotic conditions and navigating the complex selective pressures imposed by interaction networks.

Nestedness and chromatin type.

, 2023
(a) Nestedness distributions (Nij) between communities of the same type (either A, B, C, or D). (b) CDF of Nij distributions. The vertical bars indicate the Kolmogorov-Smirnov distance between ‘DD’ distribution (thick pink line) and all others. (TIF)

Relational structure of illegal wildlife hunting in China: A nationwide hunter–prey network analysis

People and Nature, EarlyView.
Abstract Illegal wildlife hunting continues to pose a major biodiversity threat in China, yet there remains no systemic relational understanding of the way in which perpetrators are linked to key taxa. To address this, here we provide a novel framework for understanding and addressing the systemic roots of wildlife crime.

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

Brazilian 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.

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

PLANTS, 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

Ecosystem 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 ...

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

Animal 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.

Nestedness Maximization in Complex Networks through the Fitness-Complexity Algorithm

Entropy, 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.

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

Plants, 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
