Relative contribution of neutral and deterministic processes in shaping fruit‐feeding butterfly assemblages in Afrotropical forests

Ecology and Evolution, 2018
The unified neutral theory of biodiversity and biogeography has gained the status of a quantitative null model for explaining patterns in ecological (meta)communities.

MoB (Measurement of Biodiversity): a method to separate the scale-dependent effects of species abundance distribution, density, and aggregation on diversity change

bioRxiv, 2018
Little consensus has emerged regarding how proximate and ultimate drivers such as productivity, disturbance, and temperature may affect species richness and other aspects of biodiversity.

Attenuation of species abundance distributions by sampling [PDF]

Royal Society Open Science, 2015
Quantifying biodiversity aspects such as species presence/ absence, richness and abundance is an important challenge to answer scientific and resource management questions. In practice, biodiversity can only be assessed from biological material taken by surveys, a difficult task given limited time and resources.

The perils of measuring biodiversity responses to habitat change using mixed metrics

Conservation Letters, 2023
Existing quantitative syntheses on how biodiversity responds to anthropogenic habitat change appear to sometimes mix different biodiversity metrics in drawing inferences.

Weed-Species Abundance and Diversity Indices in Relation to Tillage Systems and Fertilization

Frontiers in Environmental Science, 2018
Weeds pose a major threat to world agriculture by reducing detrimentally crop yield and quality. However, at the same time, weeds are major interacting components of the agroecosystems.

Plant species abundance and phylogeny explain the structure of recruitment networks.

New Phytologist, 2019
Established plants can affect the recruitment of young plants, filtering out some and allowing the recruitment of others, with profound effects on plant community dynamics. Recruitment networks (RNs) depict which species recruit under which others.

Environmental and ichthyofaunistic characteristics of Amazonian streams with and without fish farm [PDF]

Brazilian Journal of Biology, 2023
The environmental impacts caused by fish farming can lead to changes in aquatic ecosystems, especially in fish communities. In this study, we investigated possible changes in water quality, in the number of species and individuals of the same species ...

Aridity preferences alter the relative importance of abiotic and biotic drivers on plant species abundance in global drylands

Journal of Ecology, 2018
Disentangling the interplay between species‐specific environmental preferences and micro‐ and macroscale determinants of species abundance within plant communities remains challenging.

Shaping beta diversity in arid landscape through native plant species contributions: synergy of climate, soil, and species traits

Frontiers in Plant Science
Understanding how species traits, climate aridity, and soil resources interact to influence beta diversity is critical for predicting changes in plant community composition.

Composition and structure of the fauna of ground beetles (Coleoptera, Carabidae) of the Zerafshan Range

Acta Biologica Sibirica, 2023
The article presents the results of studying the fauna of ground beetles in the western part of the Zerafshan Range (Uzbekistan). The Carabidae list includes 81 species from 41 genera, 18 tribes and nine subfamilies.
