Recovered microbiome of an oviparous lizard differs across gut and reproductive tissues, cloacal swabs, and feces
<p>Microbial diversity and community function are related, and both can be highly specialized in different regions of the gut. The cloacal microbiome of Sceloporus virgatus lizards has low diversity, suggesting a specialized function, and is known to transfer antifungal microbes to eggshells during oviposition. We hypothesize that the cloacal microbiome is distinct from other parts of the digestive and reproductive systems. Here, we compare the microbiome of tissue samples from the cloaca, lower intestine, upper intestine, and oviduct. We further assessed whether common methods of microbial sampling – cloacal swabs and feces – provide accurate representations of these tissues, and whether feces might "seed" the cloacal microbiome. We found that the upper intestine and oviduct had unique microbial communities, while the lower intestine and cloaca had similar communities with lower diversity indicative of regional specialization. The cloacal community, in particular, showed extreme specialization averaging 99% Proteobacteria (Phylum) and 83% Enterobacteriacaea (Family). Cloacal swabs recovered communities similar to that of lower intestine and cloacal tissues, but fecal samples had much higher diversity and a distinct composition (62% Firmicutes and 39% Lachnospiraceae) relative to all gut regions. This result serves as a caution against the frequent assumption that fecal samples provide an accurate representation of the gut. Finally, we found that defecation did not alter the cloacal microbiome, suggesting that community is robust to perturbations from transient microbiota. </p>

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).

Regeneration data of bryophyte fragments extracted from feces of Chloephaga picta and Attagis malouinus in Navarino Island, sub-Antarctic Chile
<p class="Normal1"><span><span><span><span><span><span><span><span><span><span><span>Birds are known to act as potential vectors for the exogenous dispersal of bryophyte diaspores. Given the totipotency of vegetative tissue of many bryophytes, birds could also contribute to endozoochorous bryophyte dispersal. Research has shown that fecal samples of the upland goose (<i>Chloephaga picta</i>) and white-bellied seedsnipe (<i>Attagis malouinus</i>) contain bryophyte fragments. Although few fragments from bird feces have been known to regenerate, the evidence for the viability of diaspores following passage through the bird intestinal tract remains ambiguous. We evaluated the role of endozoochory in these same herbivorous and sympatric bird species in sub-Antarctic Chile. We hypothesized that fragments of bryophyte gametophytes retrieved from their feces are viable and capable of regenerating new plant tissue. Eleven feces samples containing undetermined moss fragments from <i>C. picta</i> and <i>A. malouinus</i>, six moss fragment samples from wild collected mosses (<i>Conostomum </i><i>tetragonum</i>,<i> Syntrichia </i><i>robusta</i>,<i> </i>and <i>Polytrichum </i><i>strictum</i>), and one spore sample from <i>C. tetragonum </i>were grown ex situ in peat soil and in vitro<i> </i>using a Gamborg (agar) medium. After 91 days, 20% of fragments from <i>A. malouinus </i>feces, 50% of fragments from <i>C. picta </i>feces, and 57% of propagules from wild mosses produced new growth. The fact that moss diaspores remained viable and can regenerate under experimental conditions following the passage through the intestinal tracts of these robust fliers and altitudinal and latitudinal migrants, suggests that sub-Antarctic birds may play a </span></span></span></span></span></span></span></span></span></span></span><span><span><span><span><span><span><span><span><span><span><span>critical, role in bryophyte dispersal.

Seed traits of seed within spider monkey, howler monkey feces, and dung beetles' dung balls
<p>These data files contain seed traits from three sources, 1) seed traits from "Seeds of Amazonian Plants", 2) Royal Botanic Gardens Kew Seed Information Database, and 3) seeds dissected from field collections of primate feces and dung balls from dung beetles. The dataset was used in the article published in Biotropica entitled "<em>Seed size and pubescence facilitate secondary dispersal by dung beetles</em>". The data mostly describes seed traits of morphospecies within the feces of brown-headed spider monkeys (<em>Ateles fusciceps</em>) and mantled howler monkeys (<em>Alouatta palliata</em>). Traits included in the data set are size, surface, length, width, shape, color, and dispersal by mammals. </p>

No significant differences nor tendencies were determined between treatment groups within every period by Tukey’s pairwise comparison test (<em>P</em> > 0.10). During the whole experiment all treatment groups received a low protein diet (CTRL). The cows in the MetLys group received rumen-protected (RP) Met (Excential Rumenpass MET, Orffa Additives) and RP-Lys (AjiPro-L, Ajinomoto H&N) during the RP-AA period. The cows in the MetLysHis group received RP-Met, RP-Lys and RP-His (experimental RP-His product, Ajinomoto Co.) during the RP-AA period.</p>

Small Mammal Exclosure Study (SMES) Rabbit Feces Data from Chihuahuan Desert Grassland and Shrubland at the Sevilleta National Wildlife Refuge, New Mexico (1995-2005)
The purpose of this study is to determine whether or not the activities of small mammals regulate plant community structure, plant species diversity, and spatial vegetation patterns in Chihuahuan Desert shrublands and grasslands. What role if any do indigenous small mammal consumers have in maintaining desertified landscapes in the Chihuahuan Desert? Additionally, how do the effects of small mammals interact with changing climate to affect vegetation patterns over time? This is data for numbers rabbit fecal pellets counted on each of the Small Mammal Exclosure Study (SMES) plots. Rabbit fecal pellets were counted from each of the 36 one-meter2 quadrats twice each year when vegetation was measured.
Data from: Pellets of proof: first glimpse of the dietary composition of adult odonates as revealed by metabarcoding of feces
Recent advances in molecular techniques allow us to resolve the diet of unstudied taxa. Odonates are potentially important top-down regulators of many insects. Yet, to date, our knowledge of odonate prey use is based mainly on limited observations of odonates catching or eating their prey. In this study, we examine the potential use of metabarcoding in establishing the diet of three adult odonate species (Lestes sponsa, Enallagma cyathigerum, and Sympetrum danae) at a site in southwestern Finland. To this purpose, we compared three different methods for extracting DNA from fecal samples: the Macherey-Nagel Nucleospin XS kit, a traditional salt extraction, and the Zymo Research Fecal Microprep kit. From these extracts, we amplified group-specific mitochondrial markers (COI and 16S rRNA) from altogether 72 odonate individuals, and compared them to comprehensive reference libraries. The three odonate species show major overlap in diet, with no significant differences between individuals of different size and/or gender, reflecting opportunistic foraging of adult odonates. Of a total of 41 different prey species detected, the most frequently consumed ones were Diptera, with additional records of six other orders. Based on our data, the best DNA extraction method is the traditional salt extraction, as it provides the most information on prey content while also being the most economical. To our knowledge, this is the first study to resolve the species-level diet of adult odonates. Armed with the appropriate methodological caveats, we are ready to examine the ecological role of odonates in both terrestrial and aquatic food webs, and in transferring subsidies between these two realms.
