   We give an explicit combinatorial formula for the Laurent expansion of any arc or closed curve on an unpunctured triangulated orbifold. We do this by extending the snake graph construction of Musiker, Schiffler, and Williams to unpunctured orbifolds. In the case of an ordinary arc, this gives a combinatorial proof of positivity to the generalized cluster algebra from this orbifold.

2. Prime Labelings of Snake Graphs

   null (Ed.)

   A prime labeling of a graph G with n vertices is a labeling of the vertices with distinct integers from the set {1,2,...,n} such that the labels of any two adjacent vertices are relatively prime. In this paper, we introduce a snake graph, the fused union of identical cycles, and define a consecutive snake prime labeling for this new family of graphs. We characterize some snake graphs that have a consecutive snake prime labeling and then consider a variation of this labeling.

5. LYCODON ALCALAI (Alcala’s Wolf Snake). DIET.

   Griffing, Aaron H.; Gamble, T.; Heinicke, Matthew P.; Brown, Joseph C.; Siler, Cameron D. (October 2019, Herpetological review)

   Lycodon alcalai is a small, terrestrial snake endemic to the northern Philippines where it is known from the islands of Batan (70 km2), Sabtang (16 km2), and Calayan (196 km2; Ota and Ross 1994. Copeia 1994:159–174; Oliveros et al. 2011. Sci. Pap. Nat. Hist. Mus. Univ. Kans. 43:1–20). Although L. alcalai has been reported to prey upon Common Tree Frogs (Polypedates leucomystax) and unidentified, soft-shelled reptilian eggs (Ota and Ross 1994, op. cit.), little natural history information is available for this species. Here, we report on a new diet item for L. alcalai: an as of yet undescribed species of scaly-toed gecko (Lepidodactylus).
