Evaluation of Trichogramma cacaeciae (Hymenoptera: Trichogrammatidae) and Blattisocius mali (Mesostigmata: Blattisociidae) in the Post-Harvest Biological Control of the Potato Tuber Moth (Lepidoptera: Gelechiidae): Use of Sigmoid Functions

Agriculture, 2022
The potato tuber moth (PTM), Phthorimaea operculella, is the main potato pest in the world, having managed to adapt to a wide range of climatic conditions, and causing damage to stored tubers.

Stock assessment and exploitation of Atlantic salmon Salmo salar L. in the river Drammenselv

Fauna Norvegica, 1986
In 1985 the total salmon run and the exploitation rate in the river Drammenselv were estimated by combining catch statistics, counts of ascending salmon in a salmon ladder at Hellefoss, and a tagging-recapture experiment of the spawning stock below the ...

Ecological ramifications of adaptation to size-selective mortality

Royal Society Open Science, 2021
Size-selective mortality due to harvesting is a threat to numerous exploited species, but how it affects the ecosystem remains largely unexplored. Here, we used a pond mesocosm experiment to assess how evolutionary responses to opposite size-selective ...

Using stochastic dynamic programming to support weed management decisions over a rotation [PDF]

, 2009
This study describes a model that predicts the impact of weed management on the population dynamics of arable weeds over a rotation and presents the economic consequences.

About the interplay of sensitive and resistant biotypes in weed populations - simulation exercises for Echinochloa crus-galli in maize crops

Julius-Kühn-Archiv, 2016
Weed species easily establish in crops with a similar life cycle. Especially mono-cropping provides best conditions for such weeds. In maize this is true for Echinochloa crus-galli, which is a C4 plant and one of the worst weeds worldwide.

Dynamic computation of population protocols [PDF]

2010 17th International Conference on Telecommunications, 2010
Population protocols provide theoretical foundations for mobile tiny device networks in which global behavior emerges from a set of simple interactions between anonymous agents. The works in this area mostly focus on studying the computational power of the model.

Contribution to the knowledge of Clethrionomys glareolus populations in forests of managed landscape in Southern Moravia (Czech Republic)

Journal of Forest Science, 2007
In intensively managed landscape, the dynamics of the bank vole (Clethrionomys glareolus, Cg) populations was studied in three types of forest complexes which differed in food supply.

Population Dynamics of Bacterial Persistence

PLoS ONE, 2013
Persistence is a prime example of phenotypic heterogeneity, where a microbial population splits into two distinct subpopulations with different growth and survival properties as a result of reversible phenotype switching. Specifically, persister cells grow more slowly than normal cells under unstressed growth conditions, but survive longer under stress
