FIG. 37. A–C, Galago demidovii MPIH 120 in Transverse Canal Foramen And Pericarotid Venous Network In Metatheria And Other Mammals
FIG. 37. A–C, Galago demidovii MPIH 120 (Galagidae, Primates), near-term fetus; D, Microcebus murinus MPIH 1962/57 (Cheirogaleidae, Primates), fetus; and E, Elephantulus fuscipes MPIH 311/E1 (Macroscelididae, Macroscelidea), fetus. Coronal sections, all to same scale. In A and B (ss. 961, 979, sides rev.), rete mirabile with ascending pharyngeal artery, internal carotid vein, and basicranial venous plexus. In C and D (ss. 1285; 91/2/3), relatively large internal jugular vein, typical of strepsirhines, receives multiply branching basicranial venous plexus. In E (s. 1558), mesocranial vascular arrangements in sengis are quite different from those seen in strepsirhines: vein (asterisk) running across tympanic roof to accompany internal carotid artery into endocranium originates from prootic sinus, therefore not homologous with internal carotid vein. Key: AC, auditory capsule; acc, alicochlear commissure; apa, ascending pharyngeal artery; AS, alisphenoid; BS, basisphenoid; bvp, basicranial venous plexus; C1, atlas vertebra; cat, cartilage of auditory tube; cbca, cerebral carotid artery; cca, common carotid artery; CEN, caudal entotympanic; cptp, caudal tympanic process of petrosal; cs, cavernous sinus; EC, ectotympanic; ecvr, extracranial arterial rete; ejv, external jugular vein; EO, exoccipital; GO, gonial; gpn, greater petrosal nerve; hp, hypophysis; ica (pra), internal carotid artery (promontorial artery); icn, internal carotid nerve; icv, internal carotid vein (= internal carotid venous plexus); ijv, internal jugular vein; MC, meckelian cartilage; mdn, mandibular nerve; PE, petrosal; pglv, postglenoid vein; pr, promontorium; REN, rostral entotympanic; rssa, ramus superior of stapedial artery; STH, stylohyal; stm, stapedius muscle; tg, trigeminal ganglion; tmc, tympanic cavity; tt, tegmen tympani; ttm, tensor tympani muscle; vg, vagus ganglion; vps, ventral petrosal sinus.
Distribution, population density and behavior of dwarf galagos (Paragalago sp.) in Taita Hills, Kenya
<p>We studied habitat preferences and behavior of dwarf galagos (<em>Paragalago </em>sp.), recently rediscovered from the Taita Hills, Kenya. Small populations of Taita dwarf galagos survive in the two largest remnants of moist montane forest. Inspection of several smaller forest fragments failed to provide evidence of additional survivors. Acoustic data on the two remaining populations were obtained with AudioMoths, and analyzed in relation to forest structure data obtained by airborne lidar and by ground-level observations. A Zero-inflated negative binomial GLMM was implemented with calls per hour as the response variable and indicator of relative population density. Our results demonstrate that Taita dwarf galagos prefer dense canopy coverage and avoid forest edges. Regarding forest height, they prefer lower 20–30 m tall forest. Forest size also significantly affects Taita dwarf galago population size. Mbololo forest (185 ha) has a relatively viable population, whereas in Ngangao forest (120 ha) dwarf galagos are nearly extinct. The calls of Taita dwarf galagos resemble calls of Kenya coast dwarf galagos (<em>Paragalago cocos</em>). However, some differences exist between the Taita animals and those recently recorded by us at the Kenyan coast, and even between the two remaining populations in the Taita Hills. In addition to other data, we present the first ever photographs of the Taita dwarf galagos from the Mbololo forest and compare them to those from Ngangao forest and the Kenya coast from Diani and Shimba Hills. We conclude that DNA studies are urgently needed to resolve the taxonomic status of both surviving populations of dwarf galagos in the Taita Hills.</p>

Figure 1. Illustrations of the recently recognized Otolemur garnettii subspecies (A), their geographic range according to the IUCN red list (B), and localities sampled in this study (C). It is worth noting that illustrations represent the extremes of variation found in the subspecies and the overall range of distribution should be interpreted as areas in which they might be expected to occur. Otolemur g. lasiotis, in particular, is known to occur in highly discontinuous distributions.
