Cross-taxa Life History Patterns Provide Powerful Insights

But need large compilations for multiple taxonomic groups

weecology.org

Created Life History Database for Birds, Mammals, Reptiles

Large On-Line Compilations

(e.g. Pantheria, AnAge)

Literature Compilations (e.g. Bennett

1986, Boyer et al 2009)

Species-specific Studies, Species

Number of Core Life History ValuesNumber of Species In Database:9802 out of 12924 Species of Birds3591 out of 5419 Species of Mammals6502 out of 9952 Species of Reptiles

Best Coverage is of Mammals and Birds

Want the Data?• The database is in review at Scientific Data,

which will publish the metadata.

• Data publicly available at the repository Dryad.

• Will announce on the Weecology Blog (jabberwocky.weecology.org)

Within Broad Taxonomic GroupsMass-specific Biomass Production in Lizards (Meiri et al 2012)
