How to convert cardinal directions into numerical form to make them applicaple for a statistical analysis?

Analysing morphology-habitat relationships in a montane plant species, I am thinking of using slope exposition (i.e., northern, southern slopes, etc.) as one of the habitat features, since a...

Does anyone have a copy of the "Rmorph" package (Windows binary) and could share it?

I am starting a plant morphometric study and have got a lot of inspiration from Julien Claude's (2008) book. It uses the "Rmorph" package quite much, but I failed to find its copy on CRAN pages. I...

Are there any precise single-criterion method and statistical program to analyse leaf shape variation in plant populations?

In a morphometric variability study of montane shrub species populations, which I have just launched, leaf shape would be quite a promising character. Although commonly used in such studies, leaf...

What should be the sample size in leaf anatomical study at population level (i.e., number of plant individuals, leaves, and measurements)?

The aim of the study is to compare montane and lowland populations of a plant species with respect to leaf anatomy. The montane populations also include those situated on different altitudes. I...

Do spider mites penetrate plant tissues with only physical force, or they use enzymes to facilitate it?

Hello to everybody. My study is focused on host preference of sucking herbivorous arthropods and, in particular, how plant leaf structural traits affect the feeding choice of herbivores. The...

Can anyone share a paper on how sucking arthropod herbivores pierce plant tissue and what factors affect their feeding choice after the probing?

I study host preference of herbivorous arthropods and the host-plant traits which may affect it. In particular, I work with greenhouse plants and sucking arthropod assemblages (spider mites,...

How to manipulate leaf structural traits in plants (e.g. hair covering, stomata length and density, lamina thickness, etc.) experimentally?

Dear colleagues, My research is focused on relations between structural features of plants and host preference of herbivorous arthropods colonizing these plants. I started working particularly...
