Complex Relationships

This book deals with ecological niche modeling and species distribution modeling, two emerging fields that address the ecological, geographic, and evolutionary dimensions of geographic distributions of species. It provides a conceptual overview of the complex relationships between ecological niches and geographic distributions of species, both across space and (perhaps to a lesser degree) through time. The emphasis is on how that conceptual framework relates to ecological niche modeling and species distribution modeling, which the book argues are complementary and are most broadly applicable to diverse questions regarding the ecology and geography of biodiversity phenomena. Part I of the book introduces the conceptual framework for thinking about and discussing the distributional ecology of species, Part II is concerned with the data and tools that have been used in the early development of the field, and Part III focuses on real-world situations to which these tools have been applied.

ABSTRACT Cabossous tatouay Desmarest, 1804 is considered a rare species in southern South America, and Rio Grande do Sul State, Brazil, records of the species are scarce and inaccurate. This study reports 40 localities for C. tatouay, and provides a map of the species' potential distribution using ecological niche modeling (ENM). The ENM indicated that in this region C. tatouay is associated with open grasslands, including the areas of "Pampas" and the open fields in the highlands of the Atlantic Forest. This study contributes to the information about the greater naked-tailed armadillo in southern Brazil, and provides data key to its future conservation.

The phlebotomine sand fly Pintomyia monticola (Costa Lima, 1932) is recorded for the first time in Brasília, central-west Brazil. A review of the geographical distribution of the species in South America is presented, and its distribution is extended. The potential geographical distribution of P. monticola is predicted based on ecological niche modeling. Ecological aspects of this species are discussed.

The genus Psammolestes is comprised of three recognized Rhodniini species: P. arthuri, P. coreodes, and P. tertius. The geographical distribution of these triatomines in South America was analyzed using ecological niche modeling. Additionally, temperature, precipitation, and altitude limits for these species were estimated. The genetic algorithm for rule-set production (GARP) was applied to predict their geographical distribution. The models used were able to predict, with high probabilities, the occurrence of P. tertius in open woodlands of South America (mainly Cerrado and Caatinga ecoregions), making it the Psammolestes species with the widest distribution. P. arthuri presented a discontinuous potential distribution covering the Venezuelan Llanos and southeastern/southwestern fringes of Amazonia. P. coreodes presented the southernmost area of distribution, occurring mainly in the Argentinean Chaco. The models also support potential areas of co-occurrence for P. tertius and P. coreodes in southwestern Brazil. Clear ecological niche differences were observed for the three species: while P. arthuri occurred in warm and humid areas, P. coreodes occupied the driest and coldest areas. P. tertius presented intermediate climatological limits and occurred in the highest altitudes. Although climatic factors may determine the triatomine distribution, biotic factors, such as the association with thornbirds (Phacellodomus), may also influence the geographical distribution of Psammolestes species. Finally, this study confirms the usefulness of ecological niche modeling as a tool for studies on biogeographical aspects of triatomines.

The understanding geography and ecology role in the distribution of Solanum lycopersicum var. cerasiforme is essential for knowledge of areas with potential for tomato production and conservation. In the present work, we analyzed the environmental conditions of the center of origin of the species in South America and we compared them with records in Mexico, particularly in the state of Veracruz, tomato domestication region. We used eight climatic variables predictors and the latitude and longitude data of the species collections registered in literature and database to run two models, the first one for the south of America and the second one for Mexico. We evaluated the models by using the partial ROC method; we conducted a niche similarity and equivalency test to compare both models. We carried out a fieldwork to observe new records of the species and register the environmental conditions in which they growth. The main climatic variables of temperature were the most important for the ecological niche modeling of South America and the ecological niche modeling of Mexico. The models performed very well cause the partial roc test showed significant value for both models1.86 y 1.71 (p<0.0001). Based on our fieldwork, we registered 27 new records, we can find wild tomatoes between 14 and 2 100 amsl in areas with a range of temperature average 19-24 ºC and annual average precipitation 1 166-2 260 mm. Finally, we find out that there is climatic differentiation between South America and Mexico (most areas of the state of Veracruz) for the species.
