Fig. 12 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 12. Lateral views of crania and mandibles of (A) Gracilinanus emiliae and (B) Hyladelphys kalinowskii based on the same specimens as in figure 11. Prominent taxonomic differences illustrated in these views include orbital size, development of the postorbital process of the jugal, braincase shape, presence of accessory cusps on upper and lower canines, and relative reduction of the third premolar.
Fig. 16 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 16. Details of upper incisor morphology of (A) Hyladelphys kalinowskii (AMNH 267338) and (B) Marmosops pinheiroi (AMNH 267341). In all examined specimens of Hyladelphys, the crowns of I2–5 are narrow, asymmetrical, and widely spaced, with no consistent size increase from front to back. By contrast, the crowns of I2– 5 in Marmosops are broad, symmetrical, overlapping or closely approximated rhomboids of posteriorly increasing size.
Data from: Structure and composition of a canopy-beetle community (Coleoptera) in a Neotropical lowland rainforest in southern Venezuela
<p>Species richness, community structure, and taxonomic composition are important characteristics of biodiversity. Beetle communities show distinct diversity patterns according to habitat attributes. Tropical rainforest canopies, which are well known for their richness in Coleoptera, represent such a conspicuous life zone. Here, I describe a canopy-inhabiting beetle community associated with 23 tree species in a Neotropical lowland rainforest. Adult beetles were sampled manually and in aerial traps using a large tower crane for a cumulative year. The sample revealed 6738 adult beetles, which were assigned to 862 (morpho-)species in 45 families. The most species-rich beetle families were Curculionidae (<em>n</em> = 246), Chrysomelidae (<em>n</em> = 121), and Cerambycidae (<em>n</em> = 89). The most abundant families were Curculionidae (<em>n</em> = 2746) and Chrysomelidae (<em>n</em> = 1409). Dominant beetle families were found in most assemblages. The beetle community consisted of 400 singletons (46.4%). A similar proportion was evident for assemblages of single tree species. I found that 74.5% of all beetle species were restricted in their occurrence on host trees to the phenological season and time of the day. This daily and seasonal migration causes patterns similar to mass effects, and therefore accounts for the high proportion of singletons.</p>

Fig. 70. Morphology of the roof of the external auditory meatus in Coendou melanurus (A, AMNH 266565) and C. insidiosus (B, AMNH 90119). In C. melanurus, the roof of the meatus has a prominent bony ridge (br) that is lacking in C. insidiosus. Scale bars = 1 mm.
Fig. 40 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 40. Results of pairwise principal components analyses of representative samples of Neacomys dubosti (dub, N = 29), N. guianae (gui, N = 6), N. paracou (par, N = 37), and N. tenuipes (ten, N = 36). For each of the six analyses illustrated, principal components were extracted from the covariance matrix of logtransformed craniodental measurements of specimens with complete data in the series identified by footnotes to table 20. The first principal component is represented by the horizontal axis in each panel, the second principal component by the vertical axis; species samples are depicted as
Fig. 61 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 61. Caudal morphology of Rhipidomys venezuelae (A, AMNH 131081) and R. nitela (B, AMNH 267021). The tail of R. venezuelae is uniformly covered by short hairs that are clearly visible without magnification but do not conceal the underlying epidermal scales; there is no terminal tuft of conspicuously longer hairs. By contrast, the caudal hairs of R. nitela increase in length from the base of that organ to the tip, where the

Fig. 22 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 22. Dorsal and ventral cranial views of (A, B) Marmosops parvidens (AMNH 267359, male) and (C, D) M. pinheiroi (AMNH 267345, male). Note species differences in size and in the relative breadth of the rostrum.
Fig. 21 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 21. Detail of auditory region in (A) Marmosops pinheiroi (AMNH 267346) and (B) Marmosa murina (AMNH 267368). In Marmosops, the tympanic wing of the alisphenoid (twa) produces an anteromedial strut (st) that partially encloses the mandibular branch of the trigeminal nerve (V3, reconstructed course shown by heavy arrow); the nerve then emerges from a secondary foramen ovale. In Marmosa, the extracranial course of the nerve is unenclosed by the alisphenoid because the anteromedial strut is absent; there is no secondary foramen ovale in this species. Other abbreviations: als, alisphenoid; bo, basioccipital; bs, basisphenoid; et, ectotympanic; fo, foramen ovale; per, periotic.
