Description

We studied how the distribution of body sizes in A. alpina across Northern Europe relates to the environment. Our aim was to confirm the existence of these two distinct phenotypes of the species and identify environmental drivers to explain their distribution. Our hypothesis was that the differentiation of the species is driven by patterns of snowmelt. We tested this by using a machine learning approach to model body sizes against environmental variables of a dataset with 1x1 km spatial and daily average temporal resolution. The data provided here are the measurements of Amara alpina pronotum width with accompanying information on environemtal variables. Climate data are publicly available from www.senorge.no under the respective coordinates given for each specimen.

Expected crawler behaviour

Use a stable, truthful User-Agent with product/version and a working contact URL. Across all IP addresses and HTTP connections used by one crawler identity, allow no more than 5 requests in flight and wait at least 20 seconds between request starts. Crawl URLs listed in the catalog sitemap, including file pages and download URLs when they are published, use conditional requests, honor Retry-After, and apply exponential backoff after errors.

The welcome page may link to the interactive repository for human navigation. Automated clients must not treat that human link as a catalog crawl target.

Read the live machine-readable crawler policy before and during a crawl. Stop crawling when it reports CPU or memory utilization at or above 80% and 80% respectively.
