title: Replication data for: Productivity of Acacia angustissima accessions at two sites in the subtropiProductivity of Acacia angustissima accessions at two sites in the subtropics

description: Low leaf biomass yields coupled with small land sizes are some of the major constraints faced by smallholder farmers that grow protein-rich fodder trees and shrubs. Given these challenges, availability of highly productive seed sources would be important to enable farmers to produce leaf fodder in sufficient quantities. 14 accessions of Acacia angustissima were evaluated for leaf, wood and total biomass production at two subtropical sites with uni-modal rainfall in ZimbLow leaf biomass yields coupled with small land sizes are some of the major constraints faced by smallholder farmers that grow protein-rich fodder trees and shrubs. Given these challenges, availability of highly productive seed sources would be important to enable farmers to produce leaf fodder in sufficient quantities. 14 accessions of Acacia angustissima were evaluated for leaf, wood and total biomass production at two subtropical sites with uni-modal rainfall in Zimbabwe, with the objective of identifying high leaf biomass yielding accessions. There were up to fourfold difference in biomass yield between the accessions. Leaf dry matter yield ranged from 1.65 to 8.81 Mg ha-1 and 3.7 to 12.4 Mg ha-1 for wood biomass at the higher altitude site (1530 m a.s.l.) but were much lower at 1272 m a.s.l. where they ranged between 0.37 and 4.88 Mg ha-1 for leaf and 0.4 and 7.2 Mg ha-1 for wood. The most productive accessions for leaf biomass were 16231 and 18579 at the higher altitude site, while 18586 and 18501 had the highest yields at the lower altitude. Although no one accession was consistently high yieldin
g across the two sites, the least productive accessions were consistently poor at both sites. The advantage of using selected superior accessions over the unselect bulk seed was up to 85%. These findings underscore the need to promote the use of only high yielding accessions rather than unselect bulk seed. This study identified new, more productive accessions of A. angustissima that potentially widens the genetic base of the germplasm assembled in Zimbabwe.

title: Replication Data for: Enrichment planting using native species (Dipterocarpaceae) with local farmers in rubber smallholdings in Sumatra, Indonesia

description: Dipterocarp species grow well in rubber plantings and do not suffer from mycobionts and abiotic factors such as soil and microclimate (particularly light availability).Here we report on the early growth of meranti in rubber agroforests in three villages in Bungo district and farmers participation in tree enrichment planting in rubber smallholdings. Survival rate of S. leprosula six months after planting ranged from 46.5 percent to 59.2 percent in the three plots and remained the same at 12 months after planting. Survival rate was lowest at the Tebing Tinggi site because wild pig (Sus scrofa) attacked. Height growth was greatest in Dusan Danau while growth in stem diameter was greatest in Dusan Danau and Tebing Tinggi. The poor growth of S. leprosula in Lubuk Beringin was the result of poor maintenance, particularly lack of weeding, by the farmer at that site. Active participation of farmers in restoration activities is essential to achieve high survival rate and performance of the planted seedlings.

title: Replication Data for: Genetic and geographic variation in growth of Balanites aegyptiaca in Niger: comparing results from provenance/progeny tests in the nursery and field

description: Some tree improvement programs in Africa use nursery tests to investigate genetic and geographic variation in growth, but do they lead to the same conclusions as field tests? We investigated this question using provenance/progeny tests (12 provenances, 108 families) of Balanites aegyptiaca from semi-arid Niger. The nursery test included treatments for time (12–16 months) and watering regime (reduced and normal). Family variation was significant for shoot diameter (Sdia), height (Sht), dry weight (Swt) and root dry weight (Rwt) in the nursery, and for tree height at 1 and 2 years (Fht-1, Fht-2) but not at 13.5 years (Fht-13.5) in the field. Provenance variation was significant only for root/shoot weight ratio (RSwt) in the nursery. Family mean Fht-1 and Fht-2 were positively correlated with all nursery growth variables except RSwt. Provenance mean Fht-2 was positively correlated with Sht, while provenance mean Fht-13.5 was negatively correlated with Swt and positively correlated with RSwt. Family mean survival at 13.5 years was positively correlated with Swt, Sdia, Fht-1 and Fht-2. Family mean Rwt, RSwt and Fht-2 increased from the more humid western to the drier eastern locations. Most correlations with nursery growth variables were stronger at 16 than at 12 months and in the normal compared with the reduced watering regime. Results suggest that Swt and Sdia may be useful for predicting family survival in the field, and Rwt and RSwt may be useful for investigating geographic variation in growth in the field. We recommend conducting both nursery and long-term field tests.

title: Replication Data for: Influence de la provenance des geniteurs et du type pollen sur la fructification sous pollinisation controlee chez Dacryodes edulis (Burseraceae)

description: Very little work has been done on the breeding of native species. Domestication requires germplasm improvement that may lead to the achievement of improved planting material for the creation of new ciltivars. Controlled cross-pollination tests were conducted on Dacryodes edulis (Burseraceae) in order to assess the influence of the provenance and the pollen type on the fruit production of 14 females accessions belonging to 09 families from 03 provenances. the crosses were performed according to a 'nested design block' in which the two types of pollen from a given provenance were used to fertilize a group of 05 female trees from the same provenance.  For each cross, the number of pollinated flowers, number of fruits set and the number of mature fruits were evaluated; the fruit setting rate (TN), the fruiting index (FI) and the fruit dropping rate (TC) were calculated and subjected to analysis of variance. Based on averages, different combinations were classified according to their performance using the 'cluster analysis'. The result showed that the fruiting index that determines the studied species 'yield varies only and significantly (p=0.01.) under the combined action of the three factors studied : the provenance, the female parent in the provenance  and the type of pollen used in the crosses.

title: Replication Data for How to be an ant on figs

description: Mutualistic interactions are open to exploitation by one or other of the partners and a diversity of other organisms, and hence are best understood as being embedded in a complex network of biotic interactions. Figs participate in an obligate mutualism in that figs are dependent on agaonid fig wasps for pollination and the wasps are dependent on fig ovules for brood sites. Ants are common insect predators and abundant in tropical forests. Ants have been recorded on approximately 11% of fig species, including all six subgenera, and often affect the fig–fig pollinator interaction through their predation of either pollinating and parasitic wasps. On monoecious figs, ants are often associated with hemipterans, whereas in dioecious figs ants predominantly prey on fig wasps. A few fig species are true myrmecophytes, with domatia or food rewards for ants, and in at least one species this is linked to predation of parasitic fig wasps. Ants also play a role in dispersal of fig seeds and may be particularly important for hemi-epiphytic species, which require high quality establishment microsites in the canopy. The intersection between the fig–fig pollinator and ant–plant systems promises to provide fertile ground for understanding mutualistic interactions within the context of complex interaction networks.

title: Replication Data for: Predicting the impact of climate change on the distribution of two threatened Himalayan medicinal plants of Liliaceae in Nepal

description: Predicting the potential distribution of medicinal plants in response to climate change is
essential for their conservation and management. Contributing to the management program, this study aimed to predict the distribution of two threatened medicinal plants, Fritillaria cirrhosa and Lilium nepalense. The location of focal species gathered from herbarium specimen housed in different herbaria and online databases were geo-referenced and checked for spatial autocorrelation. The predictive environmental variables were selected, and MaxEnt software was used to model the current and future distributions of focal species. Four Representative Concentration Pathway (RCP) trajectories of the BCC-CSM1.1 model were used as the future (2050) projection layer. The MaxEnt modelling delineated the potential distribution of F. cirrhosa and L. nepalense. The current suitability is projected towards Central and Eastern Hilly/Mountainous regions. Both species gain maximum suitability in RCP 4.5 which decline towards other trajectories for L. nepalense. Overall, both the focal species shift towards the north-west, losing their potential habitat in hilly and lower mountainous regions by 2050 across all trajectories. Our results highlight the impact of future climate
change on two threatened and valuable species. The results can be further useful to initiate farming of these medicinally and economically important species based on climatically suitable zone and for designing a germplasm conservation strategy.

title: Influence of substrate, cutting length, and hormone treatment on rooting ability of Dacryodes crassifora in the nursery

description: The study was carried out to determine the rooting ability of Dacryodes crassiflora cuttings in the nursery. A three way factorial treatment structure with substrates (3 levels), hormonal  treatment (2 levels) and cutting length (2 levels) was used to assess the rooting ability of each cutting. The trial set up as a complete randomised blocks design with 3 replications. For each treatment combination, 8 cuttings were assessed per replication making a total of 288 cuttings used in the trial. Cutting status (rooted or not, died) were recorded weekly from the 4th to the 11th week after setting. For each rooted cutting, the number of roots was determined. Data collected were compiled in an Excel file and the rooting rate computed as a number of cuttings that have effectively rooted divided by the total number of cutting used in the trial were detemined and compared amont treatment combinations.

title: Replication data for: Tree shape plasticity in relation to crown exposure

description: Trees outside closed forest stands differ in the relation between stem diameter, height and crown volume from trees that grew with neighbours close by. Whether this plasticity in tree shape varies between species in relation to their light requirement is unknown. We purposefully sampled 528 trees ranging 5–100
&#160;cm diameter at breast height growing in a range of light conditions. Across ten broad-leaved species observed in Sumatra or Kalimantan, a generic relationship was found between light exposure of the crown and a light-dependent <em class="a-plus-plus">a</em>                               <sub class="a-plus-plus">l</sub> parameter that modifies the height–diameter allometric equation (<em class="a-plus-plus">H</em>&#160;=&#160;<em class="a-plus-plus">a</em>                               <sub

In our results, vertical stretching is well predicted by light availability. In fully open conditions, trees are on average 31% shorter for the same diameter than under (partial) shade. Most of the stretching response occur
s in all species as soon as some degree of lateral shading occurs. The response, however, varies by species (8–44% reduction) in a way apparently unrelated to species’ successional status. Crown volume varied less than stem height in its relationship with stem diameter across all light conditions tested. The scaling of crown volume with stem diameter, however, differed markedly between tree species.

title: Replication data for: Farmers in Cote d'Ivoire value integrating tree diversity in cocoa for the provision of ecosystem services

description: Cote d'Ivoire produces 40 % of the world supply of cocoa but much of the plantation area is aging and declining in productivity, while opportunities for land expansion into new forest land are quickly disappearing. Rejuvenation strategies for cocoa presently coalesce either around improved varieties and greater use of agro-chemical inputs in full sun systems or eco-certification that requires trees to be integrated with cocoa. Here, we explore the possibility of uniting these approaches through building on current farmer practice of incorporating trees in their cocoa fields to improve cocoa productivity and diversify their livelihoods. We interviewed 355 farmers about trees integrated in the
ir cocoa fields across four locations in the South-West of Cote d'Ivoire in 2012, stratified by whether or not farmers were eco-certified. Despite the massive deforestation, a rich diversity of trees was found in cocoa fields and an overwhelming majority of farmers (95 %) wanted more trees and/or more tree species, regardless of their certification status or ethnic origin. There was a consensus that most trees were compatible with cocoa, but farmers also traded off negative impacts of some species against their productive contribution to their livelihood. Farmers valued tree diversity on their cocoa plots and provided detailed information on how 32 tree species interacted with cocoa in terms of soil moisture retention, soil fertility improvement and pest and disease interactions but also had key gaps in knowledge about alternative hosts of mirids and mistletoe. The majority of farmers were not aware of the certification requirements for tree species and shade cover but a much higher proportion of certified farmers (76 %) had received information about shade trees than non-certified farmers (15 %), although advice only related to eight tree species. Scope for building on local knowledge and practice to sustainably increase cocoa productivity through promoting tree diversity while enhancing other ecosystem service provision was identified and the next steps required to realize this set out.

title: CAFNET Local knowledge studies of trees in coffee systems in East Africa

description: CAFNET research has elicited local agro-ecological knowledge from coffee growing areas within the vicinity of forest reserves in Kenya, Uganda and Rwanda. Knowledge was acquired from over 200 farmers in a stratified purposive sample, using a knowledge based systems approach.   Ranking and phenology survey  Building on the local knowledge studies and on-farm tree inventories, we designed a ranking and phenology survey to be applied across the 100 farms in the three counties to test consistency of farmer knowledge about physical attributes and phenology of trees found in coffee plots and along coffee plot boundaries.
