Data from: The value of trophic interactions for ecosystem function: dung beetle communities influence seed burial and seedling recruitment in tropical forests
Anthropogenic activities are causing species extinctions, raising concerns about the consequences of changing biological communities for ecosystem functioning. To address this, we investigated how dung beetle communities influence seed burial and seedling recruitment in the Brazilian Amazon. First, we conducted a burial and retrieval experiment using seed mimics. We found that dung beetle biomass had a stronger positive effect on the burial of large than small beads, suggesting that anthropogenic reductions in large-bodied beetles will have the greatest effect on the secondary dispersal of large-seeded plant species. Second, we established mesocosm experiments in which dung beetle communities buried Myrciaria dubia seeds to examine plant emergence and survival. Contrary to expectations, we found that beetle diversity and biomass negatively influenced seedling emergence, but positively affected the survival of seedlings that emerged. Finally, we conducted germination trials to establish the optimum burial depth of experimental seeds, revealing a negative relationship between burial depth and seedling emergence success. Our results provide novel evidence that seed burial by dung beetles may be detrimental for the emergence of some seed species. However, we also detected positive impacts of beetle activity on seedling recruitment, which are probably because of their influence on soil properties. Overall, this study provides new evidence that anthropogenic impacts on dung beetle communities could influence the structure of tropical forests; in particular, their capacity to regenerate and continue to provide valuable functions and services.

Data from: Interactive effects between physical forces and ecosystem engineers on seed burial: a case study using Spartina anglica
Seed burial (i.e. vertical seed dispersal) has become increasingly valued for its relevance for seed fate and plant recruitment. While ecosystem engineers have been generally considered as the most important drivers of seed burial, the role of physical forces, such as wind or water flow, has been largely overlooked. Using tidal habitats as a model system, and a combination of flume and mesocosm experiments, we investigated the effects of 1) currents, 2) benthic animals with different engineering activities and 3) their interplay on seed burial of a common salt marsh pioneer plant, Spartina anglica. Our results reveal that in such systems, water flow can be of equal or higher importance than ecosystem engineers for seed burial. For passive seed-burying engineers (PSE), coupling their actions with currents produced synergistic seed burial effects, whereas the interactive effects were only additive for active seed-burying engineers (ASE). This paper extends current understanding of seed burial and seed bank formation by revealing the need to incorporate physical forces into seed burial mechanisms. We provide the first empirical evidence that physical forces influence seed burial by synergistically interacting with ecosystem engineers, thus highlighting the role of biophysical interactions as important drivers for vertical seed movement.
A quantitative analysis of primary dormancy and dormancy changes during burial in seeds of Brassica napus
<p>For plants inhabiting unpredictable environments, scheduling germination can be challenging. Various responses to environmental conditions have been evolved by plants; these responses combine with variation in local climate to construct germination niche. Germination process may be regulated by a number of factors, among them, the type of seed dormancy and dormancy cycling play an important role in promoting survival after dispersal. In the present study, seeds of <i>Brassica napus</i> were tested for primary conditional dormancy (CD). Dormancy changes were quantified through seed population thermal germination parameters to test whether different genotypes of <i>B. napus</i> seeds (<span>944, 966, Alestrom, Danube, Okanto and Rohan</span>) are non-dormant (ND) at the maturity or if they present primary dormancy (D or CD). In a burial experiment, <i>B. napus</i> seeds dormancy cycling in the natural soil seedbank was investigated. Germination of all genotypes decreased at 5 and >20 <sup>o</sup>C, showing narrower breadth of thermal niche for germination. Dormancy-breaking Treatments lead to the widening of thermal range permissive for germination. The lower limit (<i>T<sub>l(50)</sub></i>) and higher limit (<i>T<sub>h(50)</sub></i>) temperatures for germination decreased and increased, respectively, for non-dormant (after-ripened seeds treated with GA<sub>3</sub>) seeds compared with fresh seeds in all genotypes. In fresh seeds, the <i>T<sub>l(50) </sub></i>and <i>T<sub>h(50)</sub></i> for various genotypes ranged from 3.61 to 6.5<sup>o</sup>C and 25.0 to 29.0<sup>o</sup>C, respectively and ranged from 0.2 to 1.8<sup>o</sup>C and 35 to 41.0<sup>o</sup>C in non-dormant seeds. Thus, fresh seeds of <i>B. napus</i> are dormant at dispersal and adopt delayed germination strategies to avoid summer drought. In the burial experiment, the results indicated that<i> B. napus</i> must have D/ND cycle in which fresh seeds first become dormant and then the cycle begins (CD → D ↔ CD ↔ ND), thus adopting both risk-prone and risk- adverse strategies to spread the likelihood of survival over time.</p>
