Low‐cost fluctuating‐temperature chamber for experimental ecology

A Lowcost, Highaccuracyoptical Flowmethod Formeasuring 2d and 3d Corn Seedling Growth: Theory, Experimental Technique Andvalidation

Experimental reproducibility in flow-chamber biofilms.

The structural organization of microbial communities is influenced by many factors, e.g. nutrient composition, shear stress and temperature. This paper presents a general method for quantitative comparison of biofilm structures and assessment of experimental reproducibility between independent biofilm experiments. By using a novel computer program, COMSTAT, biofilm structures of Pseudomonas aer...

Neurospora, a potential fungal organism for experimental and evolutionary ecology

Neurospora has been a successful eukaryotic model organism for addressing a wide range of biological questions under laboratory conditions. This success was a result of early domestication of the organism for rigorous experimentation. As a result of concerted efforts by many excellent researchers for over a century, there has been enormous amount of genetic resources collected and generated for...

Trends in Ecology & Evolution Experimental RNA Evolution

The recent ability to select functional RNA molecules through combinatorial chemistry has ignited exobiology research, by offering a set of tools for testing early theories of RNA evolution without the need for organisms. This process can retrieve molecules present in as few as one in 10 sequences, which suggests that careful design may allow ‘resuscitation’ of active RNA molecules that have be...

Automatic Guidance System Development Using LowCost Ranging Devices

Autonomous guidance of agricultural vehicles for various field operations serves to increase productivity. Low cost infra-red ranging devices were used in this study to estimate the guidance directrix (offset distance (d) and heading error angle (Ø)). Two kinds of tracks were used for evaluating the performance of the infra-red sensors, one track was made of a cardboard in the laboratory and th...
