Effects of Acmella radicans Invasion on Soil Seed Bank Community Characteristics in Different Habitats

Plants
To examine the effects of the recent Acmella radicans invasion on plant community and diversity in invaded habitats, the composition, density, species richness, diversity indices, and evenness index of the soil seed bank community of two different ...

Assessment of seedling emergence method in soil seed bank in two states of washing and non-washing [PDF]

تحقیقات جنگل و صنوبر ایران, 2016
This study aimed to evaluate the results of soil seed bank in Tarbiat Modares Lowland Experimental Forest by using the two methods of washing and non-washing. Therefore, four main plots (40×40 m2)with each of them comprising 4 sub quadrats of 400 m2 were

Seed production, infestation, and viability in Acacia tortilis (synonym: Vachellia tortilis) and Acacia robusta (synonym: Vachellia robusta) across the Serengeti rainfall gradient [PDF]

, 2017
Tree recruitment in savannas proceeds in multiple stages characterized by successive filters occurring at the seed and seedling stages. The “demographic bottleneck” hypothesis suggests that such filters ultimately restrict tree density and prevent trees ...

PARP inhibitors elicit distinct transcriptional programs in homologous recombination competent castration‐resistant prostate cancer

Molecular Oncology, EarlyView.
PARP inhibitors are used to treat a small subset of prostate cancer patients. These studies reveal that PARP1 activity and expression are different between European American and African American prostate cancer tissue samples. Additionally, different PARP inhibitors cause unique and overlapping transcriptional changes, notably, p53 pathway upregulation.

Roles of seed and establishment limitation in determining patterns of afrotropical tree recruitment. [PDF]

PLoS ONE, 2013
Quantifying the relative importance of the multiple processes that limit recruitment may hold the key to understanding tropical tree diversity. Here we couple theoretical models with a large-scale, multi-species seed-sowing experiment to assess the ...

The effect of successional stage and salinity on the vertical distribution of seeds in salt-marsh soils [PDF]

, 2009
Seed bank density and similarity between seed bank and above-ground vegetation along depth were compared between two salt-marshes different in age. In addition, the effect of salinity on the variation in seed bank density and similarity between seed bank
