Fig. 22 in Herpetofauna Of The Yutajé -Corocoro Massif, Venezuela: Second Report From The Robert G. Goelet American Museum-Terramar Expedition To The Northwestern Tepuis
Fig. 22. Vocalization of Colostethus undulatus, new species; a pair of pulsed notes from the same train of couplets as the unpulsed notes in figure 21. Wideband (300 Hz) spectrogram, with frequency cursor at 3600 Hz. Expanded waveforms show both pusatile notes together (bottom) and the first (middle) and second (top) notes separately.
Fig. 5 in Herpetofauna Of The Yutajé -Corocoro Massif, Venezuela: Second Report From The Robert G. Goelet American Museum-Terramar Expedition To The Northwestern Tepuis
Fig. 5. Top: Small plateau, 1220 m elevation, just north of the conical peak (see also fig. 4). The habitat is hot, open scrubland, with frequent areas of bare rock. The numerous dark stems with terminal rosettes are the peculiar Vellozia tubiflora (Velloziaceae). This area, including an adjacent, rocky ravine (see below), is the type locality of the lizard Tropidurus panstictus. Bottom: Rocky stream bed (lower left) near the base of the conical peak shown above, habitat of Pseudopaludicola llanera and Tropidurus panstictus. Note the large block of sandstone conglomerate. (February 28, 1995)
Fig. 9 in Herpetofauna Of The Yutajé -Corocoro Massif, Venezuela: Second Report From The Robert G. Goelet American Museum-Terramar Expedition To The Northwestern Tepuis
Fig. 9. Hyalinobatrachium eccentricum, new species. Two views of the paratopotype in life (AMNH 1591643). Note the weak but distinct crossbanding on the hindlimb. The bicolored iris has a golden yellow periphery and a dark brown median section in which the expanded pupil is barely visible as a broad ellipse. Absence of the usual bright pupillary ring causes the pupil to be virtually concealed because of lack of contrast with the adjacent brown part of the iris. The dark median section of the iris appears to be somewhat changeable in size and shape (see under Remarks).
Fig. 3 in Herpetofauna Of The Yutajé -Corocoro Massif, Venezuela: Second Report From The Robert G. Goelet American Museum-Terramar Expedition To The Northwestern Tepuis
Fig. 3. The eastern escarpment of Cerro Yutaje´, as viewed from a helicopter (February 18, 1995). Top: Looking northward along the eastern rim on approach to Cerro Yutaje´. Bottom: Looking southward along the rim while leaving Cerro Yutaje´. Visible landmarks in the lower photograph include (1) Cerro Camani on horizon, right of center, and (2) farther to the right but closer, the prominent small conical peak on the southern end of the Corocoro portion of the Yutaje´–Corocoro massif (see figs. 1, 4, 5).
Fig. 7 in Herpetofauna Of The Yutajé -Corocoro Massif, Venezuela: Second Report From The Robert G. Goelet American Museum-Terramar Expedition To The Northwestern Tepuis
Fig. 7. Views of the upper Río Corocoro valley, from the slope above the 1700m camp (see arrow in fig. 6, bottom). Top: Looking northeastward (upstream) toward the Colostethus locality on far side of river. Bottom: Looking southeastward to helicopter about to sit down in the streambed at camp. The hillside above the 1700m camp is covered in TyleriaStegolepisBrocchinia scrub growing on rocky soil. Peering uphill (looking for the cameraman who had just called to him), ornithologist George Barrowclough provides a sense of scale for the density and height of the scrub vegetation. See figure 23 for interior views of the mossy gallery forest across the river.

Fig. 26. Eleutherodactylus yaviensis Myers and Donnelly, from Cerro Yutaje´, 1700m camp (not to same scale). Top: Adult male, 21 mm SVL (AMNH 159161. Middle: Adult female, 26 mm SVL (EBRG 3050). Bottom: Adult female, 28 mm SVL (AMNH 159162).
Fig. 1 in Herpetofauna Of The Yutajé -Corocoro Massif, Venezuela: Second Report From The Robert G. Goelet American Museum-Terramar Expedition To The Northwestern Tepuis
Fig. 1. Sidelooking radar image showing the Yutaje´–Corocoro massif. The names Cerro Yutajé and Cerro Corocoro apply to those parts of the massif lying to the east and to the west, respectively, of the upper valley of the Río Corocoro (see footnote 2 for synonyms). Neighboring Cerro Guanay is shown to the northwest; Cerro Yaví is off the map, about 28 km northeast of the landing field at Yutaje´. Three collecting sites for the Yutaje´–Corocoro massif are numbered as follow: 1. Cerro Yutajé camp at 1700 m elevation, on upper Río Corocoro, 5°46̍N, 66°08̍W (see figs. 6 [bottom], 7). 2. South end of Cerro Corocoro, 1220 m elevation, 5°42̍N, 66°10̍W, near prominent conical peak (see figs. 4, 5). 3. Head of dugout navigation on Río Corocoro, above Yutaje´, a fishing camp at 180 m elevation, 5°37̍N, 66°07̍W. The coordinates above were determined by GPS satellite receivers. However, positions of the numbered collecting localities are placed on this radar image from helicopter and ground observation and with reference to other topographic maps (see text)—the published map coordinates for this image are accurate to only 02̍. (From sheet NB19–12, 1:250,000, elaborated by International Aero Service Corporation and published by Comisión para el Desarrollo del Sur de Venezuela [CODESUR], Ministerio de Obras Publicas, Venezuela, 1971.)
Fig. 8 in Herpetofauna Of The Yutajé -Corocoro Massif, Venezuela: Second Report From The Robert G. Goelet American Museum-Terramar Expedition To The Northwestern Tepuis
Fig. 8. Looking southward down the upper Río Corocoro toward direction of the 1700m camp, a short distance below the 1750m Colostethus locality. The open, scoured streambed, flanked here by rocky scrubland on the west bank, is in stark contrast to the small woodland streams in dense, mossy forest on the eastern side of the valley (for overviews, see figs. 6 [bottom], 7; for interior of mossy forest, see fig. 23).
Fig. 4 in Herpetofauna Of The Yutajé -Corocoro Massif, Venezuela: Second Report From The Robert G. Goelet American Museum-Terramar Expedition To The Northwestern Tepuis
Fig. 4. Top: Helicopter view from the northcentral part of the Yutaje´–Corocoro massif, looking southward over the massif to Cerro Camani on the far horizon (February 18, 1995). The closer small conical peak is on the southern end of Cerro Corocoro; it is a constant landmark. Bottom: Approaching the conical peak seen above, still looking southward over the eroded interior of the Yutaje´–Corocoro massif (February 5, 1995). See figure 1 for orientation.
Fig. 18 in Herpetofauna Of The Yutajé -Corocoro Massif, Venezuela: Second Report From The Robert G. Goelet American Museum-Terramar Expedition To The Northwestern Tepuis

Fig. 6 in Herpetofauna Of The Yutajé -Corocoro Massif, Venezuela: Second Report From The Robert G. Goelet American Museum-Terramar Expedition To The Northwestern Tepuis
Fig. 6. Top: A broadleaved (nongramineous) tepui meadow on Cerro Corocoro, 1910 m above sea level, in the high northwestern quadrant of the Yutaje´–Corocoro massif. The dominant plants are Kunhardtia (Rapateaceae), with green straplike leaves, and Brocchinia (Bromeliaceae), the broader, yellowishleaved tank bromeliads, all growing on a sphagnum substrate (February 14, 1995). Bottom: Helicopter view near the northern edge of Cerro Yutaje´, looking northward over upper headwaters of the Río Corocoro, showing scrubland with interspersed forest (February 18, 1995). The arrow indicates a campsite at 1700 m above sea level. The forest edge across the stream from camp is the type locality of the lizard Adercosaurus vixadnexus. East of camp, paralleling the open main stream, a strip of dense, mossy gallery forest marks the course of a small woodland brook, the type locality of the frog Hyalinobatrachium eccentricum. The type locality of the frog Colostethus undulatus is situated farther up

Data from: Factors influencing herpetofauna abundance and diversity in a tropical agricultural landscape mosaic
<p>Agricultural intensification and the associated factors, including land transformation, are among the major global threats affecting biodiversity especially herpetofauna. However, little information is available about how different factors shape herpetofauna species assemblages in agricultural landscape at different spatial scales from patch (125 – 250m) to the landscape (500 – 1000m).</p> <p>We assessed the diversity of amphibians and reptiles in areas under low and high degrees of agricultural intensification and explored different factors regulating diversity at different spatial scales using four sampling methods.</p> <p>Diversity and abundance of amphibians varied significantly between the two zones, but not for reptiles. Agricultural intensification Index (AII), calculated based on agrochemical use and area under agriculture at 250m scale, seemed to affect amphibians both at patch as well as at 500m and 1000m landscape scales. The AII influenced reptilian diversity only at patch and 500m scales. Vicinity of natural forest had a stronger influence on reptilian abundance. Semi-natural vegetation impacted herpetofauna diversities at larger spatial scales. The extent of water bodies influenced the reptilian abundance at 250m patch scale and amphibian abundance both at 250m and 1000m scale. Fallow lands affected only reptilian diversity at all spatial scales. Plantation affected amphibian at all scales but reptiles only at the landscape scale. Habitat heterogeneity regulated only amphibian diversity.</p> <p>These results highlight the fact that different patch and landscape-scale factors regulate the diversity of reptiles and amphibians differentially. Such scale specific information will crucially inform future conservation action for the herpetofauna in the agricultural landscape.</p>
Impacts of pastures and forestry plantations on herpetofauna: a global meta-analysis
<p class="MsoListParagraphCxSpFirst"><span>1.</span><span> </span><span>The establishment of pastures and forestry plantations has increased globally to meet growing demands for meat and wood products. <a name="_Hlk108096120"></a>Pasture and plantation expansion often drives deforestation, which causes homogenization of biotic communities and is a major driver of the global extinction crisis. A core question is how the severity of losses varies between pastures and plantations, and in turn, how geographical location and plantation management characteristics moderate these impacts.</span></p> <p class="MsoListParagraphCxSpMiddle">2.<span> </span><span>Focusing on herpetofauna (amphibians and reptiles) as the most endangered vertebrate group, we performed a global synthesis using 41 scientific articles that reported species richness or abundance in pastures and forestry plantations relative to natural forest in 191 case studies among 19 countries. </span></p> <p class="MsoListParagraphCxSpMiddle">3.<span> </span><span>We found a severe negative effect of pasture and a less negative effect of forestry plantations on species richness and abundance of herpetofauna.</span> <span>Within plantations, species richness and total abundance were more negatively impacted in amphibians than reptiles, in the tropics, when planting exotic tree species, monocultures, large or commercial plantations, and when clearing understory vegetation.
