Figure 3 in Phytotelmata colonization in bamboo (Guadua sp.) culms in northeast Argentina
Figure 3. Hypothetic schema of a trophic web for stumps of bamboo community in Corrientes Province, Argentina. The circle represents the schematic stem wall, the arrows indicate energy flow.
Figure 2. - Nesting architecture of Xylocopanasalis; Dissected nests of Xylocopanasalis revealing the nest structure inside the bamboo culm and its residents. Measurements of the nest parameters are shown in Table 1. The diameters of the nests (excluding the nest thickness) were measured at the nest entrance, followed by the vestibulum (antechamber) length, cell length, and the inner most cell length, respectively (2a). Cells containing larvae with pollen masses and their feces were collected and weighted (2b).

Figure 1. - Nesting habitat of Xylocopanasalis; A nesting habitat of Xylocopanasalis on a makeshift roof of a restaurant in Suan Pheung district, Ratch Buri province, Thailand. The red arrows indicate locations where the bamboo culms were arranged ca. 2.50 m above the ground (1a and 1b). At the nest entrance, the female of Xylocopanasalis was dehydrating the nectar previously foraged (1c).

Phenotypic variation and genome-wide association studies of main culm panicle node number, maximum node production rate, and degree-days to heading in rice
<p>To understand the genetic basis of main culm panicle node number, maximum node production rate, and degree-days to heading in rice (Oryza sativa), we conducted genome-wide association studies using a diversity panel of 220 rice accessions and 854,832 SNP markers generated using genotyping-by-sequencing (GBS), with 1X coverage. The raw genotype data was filtered, selecting single nucleotide polymorphisms (SNPs) having less than 50% missing data and minimum allele frequency (MAF) >5%. After initial filtering, imputation was conducted using BEAGLE V4.0 in 1,075,302 SNP markers. After imputation, the dataset was filtered a second time by removing SNPs with less than 5% MAF and more than 5% missing data. A total of 854,832 SNPs were used in the genome-wide association analyses. The dataset representing the genotype data of 854,832 SNP markers by 220 rice accessions is presented here.</p>
