Endogenous biomarkers reveal diet partitioning among three sympatric species of swallows
<p>Since the early 1990s, aerial insectivorous birds have shown serious population declines in North America, but it is not clear if factors common to all species within this guild account for these declines. Among sympatric swallows, population trends differ, and this may be due to differences in ecology operating throughout the annual cycle. Although these species all feed on aerial insects, prey taxa can differ tremendously in their "aeroecology" and use by swallows. We examined the potential for dietary differences among three species of swallows, Barn Swallow (Hirundo rustica), Cliff Swallow (Petrochelidon pyrrhonota), and Tree Swallow (Tachycineta bicolor), breeding sympatrically in southern Ontario, Canada. Potential interspecific differences in nestling diet were examined using two endogenous biomarkers, DNA barcoding of nestling feces and stable isotope analysis (δ 2H, δ 13C, δ 15N) of nestling feathers. We found evidence for differences in dietary sources of provisioned young where Barn Swallows provisioned more terrestrial-based prey, Cliff Swallows provisioned an intermediate diet, and Tree Swallows the most aquatic-emergent insect diet. We suggest this information may help to identify potential factors contributing to differential declines of aerial insectivores operating on the breeding grounds, including diet quality.</p>
Figure 5 in Evidence for vocal diversity during physical interference at the perch in sympatric Carollia species (Chiroptera: Phyllostomidae): a key to social organization and species coexistence?
Figure 5. Cluster analysis of class usage per dyad during physical interference at the perch, based on Euclidean distances. Each symbol represents a specific dyad. The x-axis represents the three clusters set by k-means clustering to which a given dyad was sorted; the y-axis represents the species to which a given dyad belonged, and the z-axis represents the relative distances of each dyad from the respective cluster centre. Dyad sex composition (passive bat is given second) is indicated by different symbols, with the sex of the passive bat indicated by different colours (in red–pink dyads, the passive bat is female; in blue–turquoise dyads it is male). Note that most dyads of a given species grouped in a specific cluster, whereas no clear pattern was found for dyad sex composition or sex of the passive bat.
Figure 4 in Evidence for vocal diversity during physical interference at the perch in sympatric Carollia species (Chiroptera: Phyllostomidae): a key to social organization and species coexistence?
Figure 4. The frequency of occurrence of a class across interactions is represented by different colours for Carollia castanea (Cc), Carollia sowelli (Cs) and Carollia perspicillata (Cp). Of the 21 classes discriminated, 20 occurred in C. castanea, 12 in C. perspicillata and five in C. sowelli. The high vocal variability of C. castanea is highlighted by the presence of six rarely occurring classes specific for this species, summarized as other. Please note that class dms, selected for comparative analyses, occurred frequently across all species.

Figure 3. Oscillograms (upper panels) and sonagrams (lower panels) representing down-sweeps (sensu Knörnschild et al., 2013) emitted by the three sympatric Carollia species present at Hitoy Cerere, Costa Rica. A, C, E, parts of a dms bout of Carollia castanea (A), a dms bout of Carollia sowelli (C) and a dms bout of Carollia perspicillata (E) are given. B, D, F, for comparison, two ds syllables of C. castanea (B), two of C. sowelli (D) and four of C. perspicillata (F) are shown. Note that syllable durations and time intervals between syllables are quasi-constant within dms bouts and more variable for sequences of ds syllables.

Oscillograms (upper panels) showing the relative amplitude (rel. amp.) and sonagrams (lower panels) representing typical frequency–time contours of vocalization classes associated with the social interaction of Carollia bats landing on, grabbing or hanging on a perched conspecific: warbles (A), down-sweep-warble (B), U (C), sinus (D), convex downwardmodulated (E), a dms syllable followed by upward-modulated-sweep (F), other_6 (G), other_1 (H) followed by other_2 (I), U-warbles (J), shallow-U (K), other_3 (L) followed by flat-down-sweep (M), sinus-warble (N) and other_4 (O). A and B are examples from Carollia perspicillata; other examples are from Carollia castanea.

Figure 6 in Evidence for vocal diversity during physical interference at the perch in sympatric Carollia species (Chiroptera: Phyllostomidae): a key to social organization and species coexistence?
Figure 6. Species discrimination based on a discriminant function analysis of acoustic parameters of dms syllables. Median values for each dyad were used in the analysis. The two discriminant functions (DF1 and DF2) are given with the percentage of variance explained. Carollia castanea (Cc) is represented by circles, Carollia sowelli (Cs) by triangles and Carollia perspicillata (Cp) by squares. The corresponding centroids are shown with a bigger symbol. For each species, 95% confidence ellipses are also plotted.
One of the first cryptic mammal species discovered, when it was separated from the morphologically similar R. tumida (= R. bickhami) based on karyological studies. Karyotype of 2n = 42 of R. genowaysi is identical to that observed in R. velilla, but these species are genetically distinct; their ranges do not overlap. R. genowaysi is morphologically very similar to other species within the R. tumida complex and is sympatric with R. bickhami (2n = 34). Monotypic. Distribution. Two nearby localities in Pacific lowlands of S Chiapas, S Mexico. in Vespertilionidae

White squares at nodes indicate both <95% posterior probability (Bayesian inference) and ≥80% bootstrap (ML) node support. Right: Sexual generation for each terminal indicated; grey bars indicate the assignations of individuals to candidate species for the ABGD, bPTP, BPP, and BFD approaches. Striped grey bars indicate the omission of the signalled taxa in some of the analyses.
