SquamataBase: a natural history database and R package for comparative biology of snake feeding habits.

ABSTRACT: Public databases in taxonomy, phylogenetics and geographic and fossil occurrence records are key research tools that provide raw materials, on which broad-scale analyses and synthesis in their respective fields are based. Comparable repositories for natural history observations are rare. Publicly available natural history data on traits like diet, habitat and reproduction are scattered across an extensive primary literature and remain relatively inaccessible to researchers interested in using these data for broad-scale analyses in macroecology and macroevolution. In this paper, I introduce SquamataBase, an open-source R package and database of predator-prey records involving the world's snakes. SquamataBase facilitates the discovery of natural history observations for use in comparative analyses and synthesis and, in its current form, contains observations of at least 18,304 predator individuals comprising 1,227 snake species and at least 58,633 prey items comprising 3,231 prey taxa. To facilitate integration with comparative analysis workflows, the data are distributed inside an R package, which also provides basic functionality for common data manipulation and filtering operations. Moving forward, the continued development of public natural history databases and their integration with existing digitisation efforts in biodiversity science should become a priority.

Project description:BackgroundSiberian sturgeon (Acipenser baeri Brandt) and Beluga sturgeon (Huso huso) are two important commercial fish in China, and the feeding habits of them are very different. Diets and feeding habits are two significant factors to affect the gastrointestinal microbiota in fish. The intestinal microbiota has been reported to play a key role in nutrition and immunity. However, it is rarely reported about the relationship between the intestinal microbiota and feeding habits/diets on different Acipenseridae fish. This study is to comparative analysis of gut microbial community in Siberian sturgeon and Beluga sturgeon fed with the same diet/Beluga sturgeon fed with different diets in order to determine the effects of different feeding habits/diets on the fish intestinal microbiota.ResultsAccording to the experimental objectives, BL and BH groups were Beluga sturgeon (Huso huso) fed with low fishmeal diet and high fishmeal diet, respectively. SH group represented Siberian sturgeon (Acipenser baeri Brandt) fed with the same diet as BH group. After 16 weeks feeding trial, the intestinal microbiota was examined by 16S rRNA high-throughput sequencing technology. On the phylum level, Proteobacteria and Bacteroidetes were significantly higher in BL group than BH group, and Cyanobacteria showed the opposite trend. Compared with BH group, Proteobacteria and Firmicutes were significantly increased in SH group, whereas Cyanobacteria were clearly decreased. At the genus level, Pseudomonas and Citrobacter in BL group were significantly higher comparing with BH group, while Bacillus, Luteibacter, Staphylococcus and Oceanobacillus was lower in BH group than SH group.ConclusionsAlpha and beta diversities indicated that the intestinal microflora were significant difference between Siberian sturgeon and Beluga sturgeon when they fed with the same diet. Meanwhile, Beluga sturgeon fed with low fishmeal diet can increase the species diversity of intestinal microbiota than it fed high fishmeal diet. Therefore, feeding habits clearly affected the gastrointestinal microbiota of sturgeons. Moreover, the impact of changes in food on the gut microbiota of sturgeons should be taken into consideration during the process of sturgeon aquaculture.
