title: Data from: Species enrichment in tropical dry forest recovery: Successional patterns of seed rain attributes

description: Propagule availability limits the successional recovery of tropical dry
 forest (TDF). Despite high resprouting potential in these regrowing
 forests, the floristic enrichment of communities with reduced seed banks
 largely depends on seeds of species absent from the site (i.e.,
 allochthonous component). Successional development of vegetation structure
 and composition potentially shapes seed rain attributes by modifying
 attractiveness to dispersers or the dispersal of anemochorous seeds. We
 examined the successional and seasonal variation in seed rain richness and
 abundance across two contrasting components (autochthonous vs.
 allochthonous) and for subsets defined by dispersal mode, growth form, and
 successional guild. Monthly seed rain samples were collected over one year
 in a successional chronosequence (1–60 years). We used a Bayesian approach
 to model the responses of seed rain richness and abundance to age and
 season (wet vs. dry) by fitting generalized additive models, and a
 detrended correspondence analysis to assess the spatial autocorrelation of
 seed rain composition. Community-level seed rain abundance decreased as
 succession progressed, while community and autochthonous species richness
 increased. The allochthonous component of the seed rain responded to
 season, rather than age, with higher values in the dry season, as observed
 for most plant groups in the seed rain subsets. Dispersal modes shifted
 from anemochory to endozoochory, and from seeds of non-woody to seeds of
 woody species in later stages. The composition of seed rain exhibited
 strong spatial autocorrelation. The interplay of succession, seasonality,
 and landscape context shapes seed rain, thus confirming its important role
 in species enrichment during TDF regeneration.

 *Journal of Plant Ecology* The data come from seed traps located in a
 successional chronosequence of secondary forest plots, aged 1-60, in
 Nizanda (16° 39’ 30” N, 95° 00’ 40” W), Oaxaca state, southern Mexico.
 These data are compiled in an Excel book with five pages. **Page 1,**
 named “Species age”, contains the seed abundance for all study species and
 morphospecies recorded in the seed rain. Column "Species"
 contains the species or morphospecies recorded in the seed rain, column
 "Family" indicates botanical family, column “GF” indicates
 growth form (Tr = tree, Sh = shrub, Li = liana, Gr = graminoid, Fo = forb,
 Vi = vine), column “DS” indicates dispersal syndrome (An = anemochorous,
 Au = autochorous, Ba = barochorous, En = endozoochorous, Zo = zoochorous).
 Subsequent columns indicate plot successional age (1, 6, 8, 10, 12, 13,
 19, 21, 33, 39, 43, 60). Dashes were placed when no growth form or
 dispersal syndrome could be associated with the seed species in question.
 **Page 2,** named “Species month”, contains seed abundance data for all
 our study species and morphospecies by sampling month. Again, column
 "Species" contains the species or morphospecies recorded in the
 seed rain, column "Family" indicates botanical family, column
 “GF” indicates growth form (Tr = tree, Sh = shrub, Li = liana, Gr =
 graminoid, Fo = forb, Vi = vine), column “DS” indicates dispersal syndrome
 (An = anemochorous, Au = autochorous, Ba = barochorous, En =
 endozoochorous, Zo = zoochorous). Subsequent columns indicate the sampling
 month. Dashes were placed when no growth form or dispersal syndrome could
 be associated with the seed species in question. **Page 3**, named
 “Species month age”, contains a seed abundance matrix with columns “Age”
 (successional age), “Season” (dry or wet), and the rest of the columns
 correspond to each species or morphospecies recorded in the seed rain.
 **Page 4,** named “q0 richness”, shows the estimated Hill diversity of
 order q = 0 for each seed group. Column “Age” indicates successional age,
 “qD0” indicates estimated richness, “Season” indicates either dry or wet
 season, and “Seed group” indicates the seed categorization for the three
 seed bank components (community, allochthonous, and autochthonous),
 dispersal syndromes, growth forms, successional guilds, and woodiness
 (woody, non-woody). **Page 5,** named “seed abundance”, contains seed
 abundance and raw richness data according to successional age (column
 “Age”), month (column “Month”), trap identification (“Trap”), season
 (column “Season”), and seed groups (Column "Seed group) according to
 community components (autochthonous and allochthonous), dispersal syndrome
 (anemochorous, zoochorous and endozoochorous), growth form (tree, shrub,
 liana, graminoid, forb, vine), successional guild (pioneer = pioneer tree
 species, mature = mature forest tree especies), and woodiness (woody,
 non-woody). ### Files and variables #### File: Data_seed_rain_Nizanda.xlsx
