IODP Expedition 396 Whole-round core section composite 360 degree images

Images of the outside of hard rock whole-round sections were acquired using a linescan imager (Section Half Imaging Logger [SHIL]) and a special holder that allows each 90 degree segment of the outer surface to be positioned properly. The images were taken at a resolution of 20 lines/mm (50 micropixels). JRSO staff take these quadrant images and compile them into a side-by-side rollout photograph of the section. Composite images are available as both JPG and TIF image formats. Individual quadrant images are available as JPG images only through this report; contact the <a href="mailto:database@iodp.tamu.edu">IODP-JRSO Data Librarian</a> if quadrant TIF files (~160 MB) are needed.

FIG. 4. — A in The use of photographic color information for highthroughput phenotyping of pigment composition in Agarophyton vermiculophyllum (Ohmi) Gurgel, J.N.Norris & Fredericq

FIG. 4. — A, After color correction procedures, color values estimated for four areas on the color card (i.e., black, white, red, and blue swatches) included in each photograph showed no significant differences among light condition groups (shapes); B, After color correction using values standardized using a color card, color traits (RGB values analyzed with PCA) were more similar within thallus (numbered clusters) than among light conditions (shapes), with a few exceptions. C, Centroids estimated for each thallus (numbered clusters) and light condition (shape and color) combination showed that some light conditions could be effectively standardized with color correction procedures (e.g. blue, direct sunlight, and white light), whereas thalli photographed under other conditions showed different color profiles even after correction (e.g. indirect sunlight (triangles), and to a lesser extend yellow light (boxed Xs).

FIG. 2. — Principal components of variation for: A, R, G, and B values; B, pigment variables. Arrow directions indicate the association of each variable to PC 1 and PC 2. Arrow length indicates the relative strength of the contribution of each variable. Point color reflects the average color of each thallus; C, the major axis of variation in pigments (PC1) is best predicted by a combination of color PC1 and PC2. The dashed line represents predicted values when PC2 is low, compared to when PC2 is high (solid line); D, pigment variation along PC2 is best predicted by color variation along PC2.

FIG. 1. — Agarophyton vermiculophyllum color variation. Photographs used for color information arranged (from top left) in rank order of increasing hue value. Lower right panel shows the color of the average RGB values estimated from each image. Labels indicated the region and site of origin for each thallus. Diameter of dish in each image is 100 mm.

Implementation of biotic interactions in niche analyses unravels the patterns underneath community composition in clownfishes

Biotic interactions are key to understanding the ecology of species and communities. As such, integrating biotic interactions into ecological niche modelling methods has been a central topic of research for the last decade. Yet, the role of biotic interactions remains overlooked. Mutualistic systems constitute perfect study cases for analysing the effect of biotic interactions on species niches and communities' composition. Using the clownfish-sea anemone interaction, we integrate mutualistic interactions into a niche quantification framework to analyse the effect of biotic interactions in the estimation of species niches, and competition patterns among clownfish communities. Our results show that ignoring biotic interactions can strongly affect species' ecological niche estimations. More importantly, sea anemones seem to mediate competition among clownfishes, structure communities and allow coexistence in competitive environments. These findings strongly support the importance of biotic interactions in shaping communities. Future studies could use the proposed analytical framework, which could also serve multiple conservation purposes.
