Problem solving in plant ecology: Enhancing cognitive learning outcomes

open access: yesBiosfer
Cognitive learning outcomes (CLO) are the most important part of learning. CLO the basis of students' understanding for further learning. CLO play an important role in students' readiness to face the real world.

Comparative study of Sulina and Sfântu Gheorghe seaside flora [PDF]

open access: yesScientific Annals of the Danube Delta Institute, 2007
The seaside flora of Sulina and Sfântu Gheorghe localities was investigated in 2006. In the vegetation periods, a total of 316 plant specimens were identified. At the end of the study we determined that the species belonging to 192 genera and 64 families.

The use of chronosequences in studies of ecological succession and soil development [PDF]

open access: yes, 2010
1. Chronosequences and associated space-for-time substitutions are an important and often necessary tool for studying temporal dynamics of plant communities and soil development across multiple time-scales.

Applying trait-based models to achieve functional targets for theory-driven ecological restoration [PDF]

open access: yes, 2014
Manipulating community assemblages to achieve functional targets is a key component of restoring degraded ecosystems. The response-and-effect trait framework provides a conceptual foundation for translating restoration goals into functional trait targets,

Agronomic Estimation of Lupin (Lupinus pilosus L.) as a Prospective Crop

open access: yesAgronomy
The global dependence on a narrow range of crops poses significant risks to food security, and exploring alternative crops that enhance agrobiodiversity is crucial.

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro

open access: yesMolecular Oncology, EarlyView.
Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.

Potential phytotoxic and shading effects of invasive Fallopia (Polygonaceae) taxa on the germination of dominant native species [PDF]

open access: yes, 2011
Two species of the genus Fallopia (F. sachalinensis, F. japonica, Polygonaceae) native to Asia, and their hybrid (F. ×bohemica), belong to the most noxious plant invaders in Europe.

Insights into a long life without cancer: The case of the bowhead whale

open access: yesMolecular Oncology, EarlyView.
Long‐lived, large‐bodied organisms have evolved powerful anticancer mechanisms that preserve cellular and tissue integrity across extended lifespans. A recent study by Firsanov et al. shows that greater genome stability is a key factor underlying the remarkable longevity and cancer resistance of one such species, the bowhead whale.

Tetramorium Parvioculum Sp. N. (FORMICIDAE: MYRMICINAE), A new species of the T. Simillimum group from Gibraltar [PDF]

open access: yes, 2009
We describe a new species of Tetramorium, which has so far only been found in Gibraltar. Tetramorium parvioculum sp. n. belongs to the simillimum-group, which is of Afrotropical origin.

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

open access: yes, 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 ...
