Data from: Frugivore diversity increases evenness in the seed rain on deforested tropical landscapes
<p>The diversity of tropical forests is strongly shaped by mutualistic interactions involving plants and frugivores that disperse their seeds. However, it is little known how decreases in the diversity of frugivores can affect seed dispersal patterns, plant community composition and species' coexistence in tropical forest landscapes. Here, we investigated the effects of bird frugivore diversity on seed dispersal of rare plant species and on the magnitude of equalizing effects on the seed rain in open areas within 12 fragmented landscapes in the Brazilian Atlantic Forest. We monitored the production of bird-dispersed seeds and bird abundance in forest fragments, and sampled the seed rain and the activity of birds attracted to experimental tree nuclei established in neighboring pastures. The activity of frugivores in tree nuclei was positively correlated with the diversity of birds recorded in nearby forest fragments, and the seed rain diversity increased with frugivore activity. The proportion of seeds dispersed more frequently than expected by chance in tree nuclei increased linearly with the species' richness of birds. The richness and abundance of active frugivores in deforested areas promoted a seed rain with evenness and diversity up to five times greater than the seed pool available in forest fragments due to the proportional increase in the dispersal of rare plant species and a concomitant proportional decrease in the dispersal of dominant fruiting plants. Furthermore, every additional bird species detected in a site was associated with a 10% increase in the equalizing effect on dispersed seeds' relative abundance. Our results show that the aggregated behavior of avian frugivore communities on deforested areas results in higher species richness in the seed rain of plant communities and underscore the urgency to reduce bird species' loss and the simplification of their communities in tropical landscapes.</p>
Data from: Soil dynamics in forest restoration: a data set for temperate and tropical regions
<p>Restoring forest ecosystems has become a global priority. Yet, soil dynamics is still poorly assessed among restoration studies and lacks knowledge on how soil is affected by forest restoration process. Here, we compile information on soil dynamics in forest restoration based on soil physical, chemical and biological attributes in temperate and tropical forest regions. It encompasses 50 scientific papers across 17 different countries and contains 1,469 quantitative information of soil attributes between reference (e.g., old-growth forest) and restored ecosystems (e.g. forests in their initial or secondary stage of succession) within the same study. To be selected, studies had to be conducted in forest ecosystems, to include multiple sampling sites (replicates) in both restored and reference ecosystems, and to encompass quantitative data of soil attributes for both reference and restored ecosystems.</p> <p>We recorded in each study the following information: (i) study year; (ii) country; (iii) forest region (tropical or temperate); (iv) latitude; (v) longitude; (vi) soil class; (vii) past disturbance; (viii) restoration strategy (active or passive); (ix) restoration age; (x) soil attribute type (physical, chemical or biological); (xi) soil attribute; (xii) soil attribute unit; (xiii) soil sampling (procedures); (xiv) date of sampling; (xv) soil depth sampled; (xvi) soil analysis; (xvii) quantitative values of soil attributes for both restored and reference ecosystems; (xviii) type of variation (standard error ou deviation) for both restored and reference ecosystems; and (xix) quantitative values of the variation for both restored and reference ecosystems. These were the most common data available in the selected studies.</p> <p>This extensive database on the extent soil physical, chemical and biological attributes differ between reference and restored ecosystems can fill part of the existing gap on both soil science and forest restoration in terms of: (i) which are the critical soil attributes to be monitored during forest restoration? and (ii) how do environmental factors affect soil attributes in forest restoration? The data will be made available to the scientific community for further analyses on both soil science and forest restoration. Soil information gap during the forest restoration process and its general patterns can be addressed using this data set.</p>
