Consumptive and nonconsumptive effects of omnivorous tadpoles on aquatic invertebrate communities

open access: yesEcosphere, 2023
Consumptive effects (CEs) of predation have been well‐studied in most aquatic systems, but nonconsumptive effects (NCEs) on prey have only recently received limited attention.

Modeling large scale species abundance with latent spatial processes [PDF]

open access: yes, 2009
Modeling species abundance patterns using local environmental features is an important, current problem in ecology. The Cape Floristic Region (CFR) in South Africa is a global hot spot of diversity and endemism, and provides a rich class of species ...

The abundance of moduli, modulini and gravitinos produced by the vacuum fluctuation [PDF]

open access: yes, 1999
Moduli, modulini and the gravitino have gravitational-strength interactions, and thermal collisions after reheating create all of them with roughly the same abundance.

Long period variables and mass loss in the globular clusters NGC 362 and NGC 2808 [PDF]

open access: yes, 2011
The pulsation periods of long period variables (LPVs) depend on their mass and helium abundance as well as on their luminosity and metal abundance. Comparison of the observed periods of LPVs in globular clusters with models is capable of revealing the ...

Effects of Different Rotation Combinations of Cabbage, Kidney Bean and Maize on Soil Fungal Communities and Soil Nutrients

open access: yesAgronomy, 2023
The continuous cropping of cabbage or kidney bean results in a decrease in yield by influencing the soil environment. To decrease the damage caused by continuous cropping, ten treatments of cabbage–maize–cabbage (CMC), kidney bean–maize–cabbage (BMC ...
