Age-abundance relationships for neutral communities [PDF]
, 2015 Neutral models for the dynamics of a system of competing species are used, nowadays, to describe a wide variety of empirical communities. These models are used in many situations, ranging from population genetics and ecological biodiversity to macroevolution and cancer tumors.

Gamma spectrometric analysis of lower Danube samples from Romania [PDF]
Nuclear Technology and Radiation ProtectionThis paper focuses on the natural and anthropogenic radioactivity of sediment samples from key spots located in the Lower Danube area and the Danube Delta region. The idea of the study is to confirm that gamma spectrometry is an efficient method

Do ecological corridors increase the abundance of soil fauna?
Écoscience, 2019 Ecological corridors are areas of natural vegetation that connect two or more separate habitat patches, surrounded by a non-habitat matrix. Soil fauna is important for sustainability, conservation and soil quality. Thus, in this study, we aimed to investigate the influence of corridors on the soil faunal community in crops near savannah vegetation ...

Identifying Keystone Species in the Human Gut Microbiome from Metagenomic Timeseries using Sparse Linear Regression [PDF]
, 2014 Human associated microbial communities exert tremendous influence over human health and disease. With modern metagenomic sequencing methods it is possible to follow the relative abundance of microbes in a community over time. These microbial communities exhibit rich ecological dynamics and an important goal of microbial ecology is to infer the ...

Population ecology of the spectacled caiman (Caiman crocodilus) in the Apaporis River middle basin
Ecosphere, 2021 Population ecology studies on spectacled caimans (Caiman crocodilus) in Colombia have been few and far between with many covering short periods and defining population parameters based on relative indices (i.e., individuals/km).

Bottom-up versus top-down control and the transfer of information in complex model ecosystems [PDF]
arXiv, 2018 Ecological systems are emergent features of ecological and adaptive dynamics of a community of interacting species. By natural selection through the abiotic environment and by co-adaptation within the community, species evolve, thereby giving rise to the ecological networks we regard as ecosystems.

Model selection for ecological community data using tree shrinkage priors [PDF]
arXiv, 2020 Researchers and managers model ecological communities to infer the biotic and abiotic variables that shape species' ranges, habitat use, and co-occurrence which, in turn, are used to support management decisions and test ecological theories. Recently, species distribution models were developed for and applied to data from ecological communities.
