Fig. 1 in Extinction Disorders The Species Composition Of Metacommunities
Fig. 1. Changes of nestedness in relation to the exclusion of the rarest species from the metacommunity.

FIGURE 4 in The presence of Wilfredomys oenax (Rodentia: Cricetidae: Sigmodontinae) in São Paulo state, southeastern Brazil: a locally extinct species?
FIGURE 4: Map of the range distribution of Wilfredomys oenax. Numbered points correspond to known southeastern records from: (1) Ubatuba, São Paulo (Present work), (2) Abismo Iguatemi, Apiaí city, São Paulo (Castro & Langer, 2011), (3) Curitiba, Paraná (ÁvilaPires, 1960). Dotted circles represent data from live caught specimens and cross represents fossil records. The gray shaded area is the geographic distribution of the species suggested by IUCN (adapted from Vieira & Christoff, 2008), been considered extinct at Curitiba (heavy gray shaded area). Full solid lines indicate Brazilian Federal state boundaries; solid light gray lines indicate major rivers.
FIGURE 3 in The presence of Wilfredomys oenax (Rodentia: Cricetidae: Sigmodontinae) in São Paulo state, southeastern Brazil: a locally extinct species?
FIGURE 3: Detailed views of morphology of the skull (A-E and I), mandible (F) and upper (G) and lower (H) left molars of Wilfredomys oenax (based on MZUSP 6281, from Ubatuba, SP). Labeled structures and region includes: auditory bulla (ab), anteroflexus (af), anteroloph (al), angular notch (an), angular process (ap), anterolabial conule (aac), anterolingual conule (alc), anteromedium flexus (amf), buccinator-masticatory foramen (bmf), condyloid process (cp), capsular process of the lower incisor alveolus (cap), coronoid process (crp), incisive foramina (if), frontal (fr), foramen ovale accessorius (foa), mesopterygoid fossa (ms), nasal (na), parapterygoid fossa (pt), palatal pits (plt), sigmoid notch (sn), zygomatic notch (zn), zygomatic plate (zp), anterocone (AR), paracone (PA), protocone (PT). White arrow indicate shallow depression along the frontals. Black bars indicate comparatives width (C) and alignment (D) between structures. Note the confluence between bmf and foa as a result of the absence of bony strut on the alisphenoid (see Voss, 1991: fig. 12), and that main molar cups are typed in upper case letters with two letter abbreviation.
