1. Ecological niche modeling of Schinus molle reveals the risk of invasive species expansion into biodiversity hotspots
Abstract: Invasive species need a closer look on the threats they may cause to the environment, mainly considering the scenario of climatic changes predicted for the next decades. Schinus molle is a pioneer tree native from South America, reported as an important invasive species in four continents. Using ecological niche modeling we show that a wide area ov

3. Global warming decreases the morphological traits of germination and environmental suitability of Dipteryx alata (Fabaceae) in Brazilian Cerrado
ABSTRACT We experimentally evaluated how different temperatures affect germination of individual seedlings of Dipteryx alata, and estimated the impact of climate change on the species using ecological niche modeling. A total of 240 seeds were randomly distributed among three different temperature treatments (32 ºC, 36 ºC, and 40 ºC), and monitored for 35

4. Ecological niche differentiation between Acanthodactylus micropholis and A. khamirensis (Sauria: Lacertidae) in southern Iran
ABSTRACT Acanthodactylus micropholis Heidari, Rastegar-Pouyani, Rastegar-Pouyani & Rajabizadeh, 2013 and A. khamirensis Blanford, 1874 are genetically and morphologically distinct, but their ecological differentiation has not previously been evaluated. The ecological niche models of these two sister species Acanthodactylus were reconstructed using climate an

5. Genetic and ecological niche modeling of Calydorea crocoides (Iridaceae): an endemic species of Subtropical Highland Grasslands
Abstract Evolutionary analyses have been widely used for evaluation of genetic diversity of natural populations and correlate these data to the fitness of the species, especially in the case of threatened species. Calydorea crocoides occurs in a restricted area at altitudes from 800 to 1500 m in southern Brazil and is considered endangered. A study assessing

6. Climatically-mediated landcover change: impacts on Brazilian territory
ABSTRACT In the face of climate change threats, governments are drawing attention to policies for mitigating its effects on biodiversity. However, the lack of distribution data makes predictions at species level a difficult task, mainly in regions of higher biodiversity. To overcome this problem, we use native landcover as a surrogate biodiversity, because i

7. Vegetation loss and the 2016 Oropouche fever outbreak in Peru
BACKGROUND Oropouche virus causes Oropouche fever, an arboviral disease transmitted mainly by midges of the genus Culicoides and Culex mosquitoes. Clinical presentation of Oropouche fever in humans includes fever, headache, rash, myalgia, and in rare cases spontaneous bleeding and aseptic meningitis. Landscape change has been proposed as a driver of Oropouc

8. Geographic distribution model for Mabuya agmosticha (Squamata: Scincidae) in northeastern Brazil
The Neotropical lizard Mabuya agmosticha Rodrigues, 2000 is a habitat-specialist of thorny bromeliads in rocky outcrops of northeastern Brazil. Its distribution in the Caatinga Domain is most likely relictual. In recent years, new surveys conducted in northeastern Brazil have revealed new records of the species in the Caatinga and also in the Atlantic Forest

9. Leishmaniasis transmission: distribution and coarse-resolution ecology of two vectors and two parasites in Egypt
Introduction: In past decades, leishmaniasis burden has been low across Egypt; however, changing environment and land use has placed several parts of the country at risk. As a consequence, leishmaniasis has become a particularly difficult health problem, both for local inhabitants and for multinational military personnel. Methods: To evaluate coarse-resol

10. Modelagem de nicho ecológico aplicada à conservação do patomergulhão (Mergus octosetaceus, Vieillot, 1817) no Brasil / Ecological niche modeling applied to the conservation of Brazilian Merganser (Mergus octosetaceus, Vieillot, 1817) in Brazil
O pato-mergulhão (Mergus octosetaceus) é uma espécie criticamente ameaçada de extinção cujas maiores populações na natureza estão abrigadas em unidades de conservação no Brasil. As principais ameaças à sobrevivência da espécie são a perda e a degradação de seu hábitat natural pela interferência antrópica. Foram utilizados nove diferentes

11. Information theory and adaptivity in the species distribution modeling. / Teoria da informação e adaptatividade na modelagem de distribuição de espécies.
Species distribution modeling is a technique the purpose of which is to estimate models based on ecological niche. These models can assist decision making processes, planning and carrying out actions aiming at environmental conservation and preservation. There are several tools designed for species distribution modeling, such as the open- Modeller framework,

12. CONSERVAÇÃO VERSUS CONFLITOS SOCIOAMBIENTAIS (COMUNIDADE JATOBÁ) NO FUTURO PARQUE ESTADUAL DAS DUNAS: Barra dos Coqueiros, Sergipe. / SOCIAL AND ENVIRONMENTAL CONSERVATION VERSUS CONFLICT (COMMUNITY JATOBÁ) THE FUTURE OF DUNES STATE PARK: Barra dos Coqueiros, Sergipe.
The conservation of the biodiversity of the dunes hás raised social interest and as a measure already politicized in the State, the environmental institutions have positioned themselves in defense of the creation in the future of the Parque Estadual das Dunas. There are two issues around the creation of a Unity of Whole Protection in the area: the first one
