Determination of their provenance, taxonomic identification, age, and mode and route of acquisition (including possible captive breeding), however, has commonly remained in the domain of speculation. For example, Amazonia has long been treated as an undifferentiated source of macaw feathers. We present key findings of our cross-disciplinary investigation of feathered ornaments that decorated the false heads of Late Intermediate period funerary bundles excavated in 2005 at the Max Uhle cemetery in front of the famed Painted Temple at Pachacamac, Peru. Our international team composed of zoologists and geneticists as well as archaeologists conducted AMS radiocarbon dating, aDNA, and isotopic (C, N) analyses of excavated feather samples. Additionally, landscape modeling based on resistance surfaces allowed us to propose possible modes and routes of feather acquisition. Overall, implications of our findings on the key issues identified above are discussed.}, year = {2025}, pages = {664-664}, orcid-numbers = {Oláh, György/0000-0002-7935-8843} } @CONFERENCE{MTMT:36273852, title = {The role of genetics in parrot conservation}, url = {https://m2.mtmt.hu/api/publication/36273852}, author = {Oláh, György}, booktitle = {International Psittacine Congress [Virtual]: Program and Abstract Book}, unique-id = {36273852}, abstract = {Parrots are a well-studied, diverse group of birds distributed mainly in tropical and subtropical regions. One-third of their species face extinction today, mainly due to anthropogenic threats. High global and domestic demand for parrots as pets, and consequent removal from the wild for the illicit trade have significantly contributed to their severe decline worldwide. Emerging tools in genetics have made major contributions to understanding basic and applied aspects of parrot biology and conservation in the wild and in captivity. In this plenary, I show how genetic methods have transformed the study of parrots by summarizing important milestones in the advances of genetics and their implementations in research on parrots. I will mainly focus on describing how genetics helped to further knowledge in conservation genetics through examples from the literature and my collaborative research projects. The application of genetic techniques to the study of parrots has far-reaching implications for addressing diverse research aims in a highly threatened and charismatic clade of birds.}, year = {2025}, pages = {40-40}, orcid-numbers = {Oláh, György/0000-0002-7935-8843} } @CONFERENCE{MTMT:36273855, title = {Abundance of Eclectus Parrots on Seram Island, Indonesia}, url = {https://m2.mtmt.hu/api/publication/36273855}, author = {Nandika, D and Agustina, D and Daryono, BS and Ali, AK and Eddy, L and Prawiradilaga, DM and Oláh, György}, booktitle = {International Psittacine Congress [Virtual]: Program and Abstract Book}, unique-id = {36273855}, abstract = {Eclectus parrots is one of the genera included in the Psittacidae family. This genus has recently been divided into 5 species in the IOC v14.1 (2024): Eclectus roratus (3 subspecies), E. cornelia, E. riedeli, E. polychloros (3 subspecies) and E. infectus (extinct). Subspecies of Eclectus roratus westermani from Banda islands, was extinct before known. Manusela National Park in Seram Island is one important Moluccan eclectus distribution area. Massive exploitation of all types of parrots has resulted in a sharp decline in their population in nature. This study attempts to monitor the Moluccan eclectus population in the Manusela National Park Area in 2020 and 2023. The survey method was carried out in the morning at 07.00-10.00 using the fixed width line transect (FWLT) method with a distance between lines of one km and a visibility of 50 m. The survey was conducted by taking random locations representing all resorts in Manusela National Park. The difference in the number of routes in each survey location is adjusted to the conditions and landscape at the survey location. In the southern region of the Manusela National Park Area, the habitat conditions are generally steep, have sharp slopes, making it difficult for observation. The density of the Moluccan eclectus is very low, from the five survey locations recorded each at Wailomatan Moso resort, Solea Sasarata resort, and Kaloa Sariputih resort each 4 individualss/10 ha, Yamitala Saunulu resort 2 individuals/10 ha, and swamps along the river at the Sasarata resort 5 individuals/10 ha. Comparing data between 2020 and 2023, the population increased from 1 individual/10 ha to 4 individual/10 ha. However, this does not mean that the species is in a safe condition, but this increase is due to the location and area of the survey required.}, year = {2025}, pages = {100-100}, orcid-numbers = {Oláh, György/0000-0002-7935-8843} } @article{MTMT:36375165, title = {Cyclosa Menge 1866 (Araneidae) orb-weavers build stabilimenta that resemble larger spiders}, url = {https://m2.mtmt.hu/api/publication/36375165}, author = {Oláh, György and Torres, Phil and Pomerantz, Aaron and Kirby, Richard and Baxter, Simon and Grados, Juan and Reeves, Lawrence E.}, doi = {10.1002/ece3.72371}, journal-iso = {ECOL EVOL}, journal = {ECOLOGY AND EVOLUTION}, volume = {15}, unique-id = {36375165}, issn = {2045-7758}, abstract = {Orb-weaving spiders are known to create stabilimenta – silk situated at particular locations of the web.

Here, we provide the first scientific record of this unique behavior in two orb-weaving spiders (Cyclosa spp., Araneidae) from the tropical forests of Peru and the Philippines. We report that these spiders construct stabilimenta composed of detritus and silk, arranging the debris in the web into a shape that visually resembles the silhouette of a larger spider.
