Ecomorphological Convergence<br />

Description<br />

This data set gives ecomorphological informations about 129 bird species.<br />

Usage<br />

data(ecomor)<br />

Format<br />

ecomor is a list of 7 components.<br />

forsub is a data frame with 129 species, 6 variables (the feeding place classes): foliage, ground ,<br />

twig , bush, trunk and aerial feeders. <strong>The</strong>se dummy variables indicate the use (1) or no use (0)<br />

of a given feeding place by a species.<br />

diet is a data frame with 129 species and 8 variables (diet types): Gr (granivorous: seeds), Fr<br />

(frugivorous: berries, acorns, drupes), Ne (frugivorous: nectar), Fo (folivorous: leaves), In<br />

(invertebrate feeder: insects, spiders, myriapods, isopods, snails, worms), Ca (carnivorous:<br />

flesh of small vertebrates), Li (limnivorous: invertebrates in fresh water), and Ch (carrion<br />

feeder). <strong>The</strong>se dummy variables indicate the use (1) or no use (0) of a given diet type by a<br />

species.<br />

habitat is a data frame with 129 species, 16 dummy variables (the habitats). <strong>The</strong>se variables<br />

indicate the species presence (1) or the species absence (0) in a given habitat.<br />

morpho is a data frame with 129 species abd 8 morphological variables: wingl (Wing length, mm),<br />

taill (Tail length, mm), culml (Culmen length, mm), bilh (Bill height, mm), bilw (Bill width,<br />

mm), tarsl (Tarsus length, mm), midtl (Middle toe length, mm) and weig (Weight, g).<br />

taxo is a data frame with 129 species and 3 factors: Genus, Family and Order. It is a data frame of<br />

class ’taxo’: the variables are factors giving nested classifications.<br />

labels is a data frame with vectors of the names of species (complete and in abbreviated form.<br />

categ is a data frame with 129 species, 2 factors : ’forsub’ summarizing the feeding place and ’diet’<br />

the diet type.<br />
