Ecosystem recharge by volcanic dust drives broad-scale variation in bird abundance [PDF]

open access: yes, 2015
Across the globe, deserts and volcanic eruptions produce large volumes of atmospheric dust, and the amount of dust is predicted to increase with global warming.

Heathland Restoration Techniques: Ecological Consequences for Plant-Soil and Plant-Animal Interactions [PDF]

open access: yes, 2011
We compare the soil and plant community development during heathland restoration on improved farmland when achieved through soil stripping with that achieved through soil acidification.

Survey of epigeic spiders (Arachnida: Araneae) in a litchi orchard in Mpumalanga, South Africa

open access: yesKoedoe: African Protected Area Conservation and Science
Spiders were sampled using pitfall traps over two 21-day periods in July 2020 and November 2020 at five sites within a litchi orchard in Hazyview, located in the Mpumalanga Lowveld of South Africa.

Long-term species richness-abundance dynamics in relation to species departures and arrivals in wintering urban bird assemblages [PDF]

open access: yes, 2019
Temporal dynamics of local assemblages depend on the species richness and the total abundance of individuals as well as local departure and arrival rates of species. We used urban bird survey data collected from the same 31 study plots and methods during

Biodiversity on island chains: neutral model simulations

open access: yes, 2010
A neutral ecology model is simulated on an island chain, in which neighbouring islands can exchange individuals but only the first island is able to receive immigrants from a metacommunity.

High‐frequency and long‐term observations of eDNA from imperiled salmonids in a coastal stream: Temporal dynamics, relationships with environmental factors, and comparisons with conventional observations

open access: yesEnvironmental DNA, 2022
A greater understanding of eDNA behavior in the environment is needed before it can be employed for ecosystem monitoring applications. The objectives of this study were to use autonomous sampling to conduct long‐term, high‐frequency monitoring of the ...

Rotifer communities of Deepor Beel, Assam, India: richness, abundance and ecology

open access: yesJournal of Threatened Taxa, 2010
Plankton samples collected from two sampling stations of Deepor Beel (a Ramsar site in Assam, northeastern India) between November 2002 and October 2003, reveal 110 and 100 species of Rotifera, exhibit monthly richness ranging between 43-65 (56 plus or ...

Road Zone Effects in Small-Mammal Communities

open access: yesEcology and Society, 2009
Our study focused on the putative effects of roads on small-mammal communities in a high desert region of southern Utah. Specifically, we tested whether or not roads create adjacent zones characterized by lower small- mammal densities, abundance, and ...

Linearity and Scaling of a Statistical Model for the Species Abundance Distribution

open access: yes, 2001
We derive a linear recursion relation for the species abundance distribution in a statistical model of ecology and demonstrate the existence of a scaling ...

Arboreal twig-nesting ants form dominance hierarchies over nesting resources. [PDF]

open access: yes, 2019
Interspecific dominance hierarchies have been widely reported across animal systems. High-ranking species are expected to monopolize more resources than low-ranking species via resource monopolization. In some ant species, dominance hierarchies have been
