Spatial distribution of the greater rhea, Rhea americana (Linnaeus, 1758), in Rio Grande do Sul, southern Brazil: citizen-science data, probabilistic mapping, and comparison with expert knowledge

Luza, A. L., Rodrigues, A. V., Mamalis, L., & Zulian, V. (2023, August 21). ORNITHOLOGY RESEARCH, Vol. 8.

author keywords: Area of occupancy; Bayesian models; Hierarchical modeling; Imperfect detection; Species distribution modeling
TL;DR: The greater rhea distribution was exclusively explained by the spatial autocorrelation component, suggesting that the species expanded its distribution towards the north of the state, reaching the Atlantic Forest, following deforestation and agriculture expansion. (via Semantic Scholar)

Endemic and Threatened <i>Amazona</i> Parrots of the Atlantic Forest: An Overview of Their Geographic Range and Population Size

Diversity.

By: V. Zulian*, D. Miller* & G. Ferraz*

author keywords: Amazona; Psittacidae; species distribution models; data integration models; occupancy models; citizen-science; population size; count data
TL;DR: Four species of Amazona are studied that are dependent on a highly vulnerable biome: the Brazilian Atlantic Forest, and abundance estimates and counts are compiled, and site-occupancy models of their geographic range are developed. (via Semantic Scholar)

Improving estimation of species distribution from citizen-science records using data-integration models

Zulian, V., Miller, D. A. W., & Ferraz, G. (2021, April 11).

By: V. Zulian*, D. Miller* & G. Ferraz*

TL;DR: This paper integrates planned survey data from roost counts with opportunistic samples from eBird, WikiAves and Xeno-canto citizen-science platforms to map the geographic range of the endangered Vinaceous-breasted Parrot, revealing an area three times larger than the ‘Extant’ area reported in the IUCN Red List.

author keywords: Endangered species; Imperfect detection; N-mixture model; Psittacidae; Roost count; Vinaceous-breasted parrot
TL;DR: Assessments of abundance and geographic range are larger than those currently reported by the IUCN, and it is suggested the Vinaceous-breasted Parrot should remain in the ‘Endangered’ I UCN threat category pending further investigation of population trends. (via Semantic Scholar)

Combined impacts of multiple non-native mammals on two life stages of a critically endangered Neotropical tree

Biological Invasions, 20(11), 3055–3068.

By: F. Dénes*, J. Tella*, V. Zulian*, N. Prestes*, J. Martı́nez* & F. Hiraldo*

author keywords: Araucaria angustifolia; Exotic species; Invasion ecology; Invasive species; Keystone species; Life stages; Seed predation
TL;DR: It is found that Paraná pine seeds constitute an autumn food resource for a native community richer than previously thought, with 70 bird and mammal species as confirmed or potential seed consumers, of which 40 were not previously recognized as such. (via Semantic Scholar)

Endangered plant-parrot mutualisms: seed tolerance to predation makes parrots pervasive dispersers of the Parana pine

Scientific Reports, 6(1).

MeSH headings : Animals; Brazil; Ecosystem; Endangered Species; Feeding Behavior / physiology; Geography; Parrots / physiology; Pinus / physiology; Seed Dispersal; Seeds / physiology
TL;DR: The dual role of parrots as predators and dispersers of the Critically Endangered Parana pine represents a thus far overlooked key plant-parrot mutualism, in which both components are threatened with extinction. (via Semantic Scholar)
