MADERA: A standardized Pan-Amazonian dataset for tropical timber species
<p>We compiled and presented a dataset for all timber species reported in the Amazon region from all nine South American Amazonian countries. This was based on official information from every country, as well as from two substantial scientific references. We verified the standard taxonomic names from each individual source, using the Taxonomic Name Resolution Service (TNRS) and considered all Amazonian tree species with DBH ≥ 10 cm. We also obtained estimates of the current population size for most species from a published approach based on data from 1,900 tree inventory plots (1-hectare each) distributed across the Amazon region and part from the Amazon Tree Diversity Network (ATDN). We then identified the hyperdominant timber species. In addition, we overlapped our timber species list with data for species that are used for commercial purposes, according to the International Tropical Timber Organization (ITTO), the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the International Union for Conservation of Nature (IUCN) taxa assessment and Red List categories. Finally, we also included IUCN Red List categories based on combined deforestation, and climate change scenarios for these species. Our final Amazonian timber species dataset contains 1,112 unique species records, which belong to 337 genera and 72 families from the lowland Amazonian rainforest, with associated information related to population, conservation, and trade status of each species. The authors of this research expect that the information provided will be useful to strengthen the public forestry policies of the Amazon countries, inform ecological studies, as well for forest management purposes. </p>

Figure 2 in Does nutritional status constrain adoption of more costly and less risky foraging behaviour in an Amazonian shelter-building spider?
Figure 2. Relationship between predicted probability of spider Hingstepeira folisecens (Hingston 1932) (Araneidae) exhibiting a pulling foraging behaviour to catch prey and body condition index (BCI – standardized residuals from a regression of abdomen volume on carapace area) in one region of Central Amazonia, Brazil. '1' represents occurrence of pulling behaviour and '0' represents absence of spider response or use of pursuing behaviour (n = 19).
Fig 1 in A distinctive new species of gnatcatcher in the Polioptila guianensis complex (Aves, Polioptilidae) from western Amazonian Brazil
<p>Figure 1.</p> <p>Geographic distribution of Polioptila attenboroughi and of documented records of P. paraensis in Amazonian Brazil. A red star marks the type locality of P. attenboroughi at “Tupana Lodge”. And letters adjacent to red locality dots provide documentation: S = specimen; V = vocal recording; n = undocumented sight-records. White dots mark documented records of presumed P. paraensis (type locality Benevides, Pára, near Belém), including on P. marking a site documented by a photograph archived on the website www.wikiaves.com.br (WA589871). Black lines mark the boundaries of Brazilian states as indicated by their abbreviations: AM = Amazonas; RO = Rondônia; MT = Mato Grosso; PA = Pará. The federal highways BR-319 (linking Manaus and Porto Velho, running north-south) and BR-230 (“Transamazônica” running mostly east-west) are shown in white.</p>
Fig 2 in A distinctive new species of gnatcatcher in the Polioptila guianensis complex (Aves, Polioptilidae) from western Amazonian Brazil
<p>Figure 2.</p> <p>Spectrograms of characteristic vocalizations of Polioptila attenboroughi for comparison with homologous vocalizations of the Polioptila schistaceigula complex, and of other taxa presented at the same spectrogram scales by Whitney and Álvarez (2005). A) P. attenboroughi loudsong (Amazonas, ca 50 km south Humaitá; 17 December 2011, Whitney recording BMW-15034); B) P. paraensis loudsong (Pará, ca 53km west Jacareacanga; 14 July 2008, Whitney recording BMW-4261). This is the same locality from which the tissue sample representing P. paraensis used in this study was collected. The sample of loudsongs measured in the vocal analysis, from nearer the type locality of P. paraensis, was considerably faster-paced (see data in SI, and spectrogram C in figure 3 of Whitney and Álvarez 2005); C) P. attenboroughi complex song (Amazonas, ca 50 km south Humaitá; 19 December 2010, Whitney recording BMW-11956). D) P. schistaceigula (Panamá; Darién, near Cana; 4 January 1993, Whitney recording ML-161468); E) P. attenboroughi multi-note call (same recording as A, above); F) P. schistaceigula multi-note call (same recording as D, above). Multi-note call may comprise more notes than this example; G) P. guianensis multi-note call (Amazonas, ca. 60km north Manaus, INPA tower; 13 September 2010, Whitney recoding BMW-10821); H) P. attenboroughi multi-note rasp (same recording as C, above); and I) P. schistaceigula multi-note rasp (same recording as D and F above.</p>
Fig 3 in A distinctive new species of gnatcatcher in the Polioptila guianensis complex (Aves, Polioptilidae) from western Amazonian Brazil
<p>Figure 3</p> <p>Phylogenetic relationships with the Polioptila schistaceigula/guianensis complex recovered by Bayesian analysis based on 1941 bp of ND2 sequences. Numbers refer to posterior probabilities values and genetic distances (% of average uncorrected p sequence divergence) between sister groups associated with the labeled nodes (see Table 2 in SI of detailed information). Note the paraphyly of taxa formerly grouped as subspecies of P. guianensis (guianensis and paraensis) and the new taxon P. attenboroughi described herein. High statistical support value (i.e., 1) and sequence divergence levels associated with nodes grouping Polioptila attenboroughi, P. guianensis, P. paraensis, and P, schistaceigula are, in concert with documented levels of phenotypic differentiation, consistent with their ranking as species-level taxa.</p>

Fig. 7. Alfonso Olalla at the Tyler-Duida Expedition's Central Camp on Mount Duida, photographed by G.H.H. Tate on February 16, 1929. Notice the large numbers of prepared specimens, including many mammals, stored in paper sleeves ready for shipment to New York. Tate's diary on the Tyler-Duida Expedition, now in the Department of Mammalogy at the AMNH, describes his visits with Alfonso, in which they discussed the natural history of birds and mammals.
Fig. 3 in Alfonso Olalla And His Family: The Ornithological Exploration Of Amazonian Peru
Fig. 3. Map of the vicinity of Indiana (the Olallas' ''Pto. Indiana''), departamento Loreto, Peru. The mouth of the Río Napo is about 20 km east of Indiana although the river passes within 3 km to the north. South of the Río Amazonas seasonally flooded lowlands extend to the arcuate portions of the Río Vainilla as indicated. This map and the following ones are based on satellite images from Google Earth (accessed March–December 2008).

Fig. 6 in Alfonso Olalla And His Family: The Ornithological Exploration Of Amazonian Peru
Fig. 6. Map of the origin of the Río Ucayali, departamento Ucayali, Perú. The Ucayali begins at the confluence of the Río Tambo and the Río Urubamba near the current town of Atalya. Foothills of the Andes paralleling the Ucayali, within the dashed line, include a spur that nearly reaches the river. Dots show the locations of several current villages mentioned in the text. The Olallas used three camps in this area (1–3): at the mouth of the Río Urubamba (''Boca Río Urubamba,'' 1) and nearby downstream to the west (''Santa Rosa,'' 2) and east (''Lagarto,'' 3) of the general course of the Ucayali.
Fig. 1 in Alfonso Olalla And His Family: The Ornithological Exploration Of Amazonian Peru

Fig. 4 in Alfonso Olalla And His Family: The Ornithological Exploration Of Amazonian Peru
Fig. 4. Map of the lower courses of the ríos Orosa and Apayacu, departamento Loreto, Peru. Seasonally flooded lowlands extend from the Río Amazonas northward to the dashed line and southward to the arcuate portions of the Río Orosa. The Olallas' locality ''Orosa'' was most likely at or near the circle (1, see text). Their ''Apayacu'' was at the current town of that name (2), on a small island between the mouth of the Río Apayacu and the Río Amazonas.
