Revisión a nivel ibérico de la distribución del topillo de Cabrera o iberón, Ib...
Garrido-Garcia, José; Rosário, Inês; Gisbert, Julio; García-Perea, Rosa; Cordero, Ana Isabel; López-Alabau, Antonio; Mathias, Maria da LuzNeste estudo é apresentado um mapa de quadrículas UTM 10x10 km para toda a área de distribuição de Iberomys cabrerae. A partir dos dados obtidos destacamos que a) as 420 quadrículas com dados se concentram em 4 grandes núcleos disjuntos (Luso-Carpetano, Montibérico, Bético y Prepirenaico), das quais o mais importante é o Luso-Carpetano e o mais pequeno, isolado e ameaçado é o Preirenáico; b) é necessário intens...
The influence of local, landscape and spatial factors on the distribution of the...
Santos, Sara; Mathias, Maria da Luz; Mira, AntónioThis study evaluated the relative contributions of local and landscape factors, and of spatial structure on the regional distribution of both the Lusitanian (Microtus lusitanicus Gerbe, 1879) and Mediterranean pine voles (Microtus duodecimcostatus de Selys-Longchamps, 1839) over an area of 1613 km 2 within a Mediterranean landscape in central Portugal. Three sets of explanatory variables (20 local, 23 landscape...
Local coexistence and niche differences between the Lusitanian and Mediterranea...
Santos, Sara; Mathias, Maria da Luz; Mira, AntónioIn the present study, we analyzed the coexistence pattern of the Lusitanian pine vole (Microtus lusitanicus) and the Mediterranean pine vole (Microtus duodecimcostatus) in a potential area of sympatry in a Mediterranean landscape (Portugal). We also determined the relative contribution of local, landscape, and spatial factors explaining the differences in the distribution patterns of the two spe...
Spatial and temporal ecology of the Lusitanian pine vole ( Microtus lusitanicu...
Santos, Sara; Lourenço, Rui; Mathias, Maria da Luz; Mira, AntónioIn this study we report the fi rst data on the spatial ecology of the Lusitanian pine vole ( Microtus lusitanicus ). Data report to the breeding season and to a traditional Mediterranean agricultural landscape in Central Portugal, using radio-telemetry methods. We documented large home range areas with values of 1042 m 2 for males and 862 m2 for females (MCP method; 95% kernel method with values of 2...
Factors influencing large-scale distribution of two sister species of pine vole...
Santos, Sara; Mira, António; Mathias, Maria da LuzThis paper models the distribution of Lusitanian and Mediterranean pine voles in Portugal.
Using presence signs to discriminate between similar species
Santos, Sara; Mira, António; Mathias, Maria da LuzThe Lusitanian and the Mediterranean pine voles (Microtus lusitanicus Gerbe, 1879 and Microtus duodecimcostatus de Selys-Longchamps, 1839) are fossorial sister species and have an allopatric pattern of distribution in Portugal, which includes a potential sympatry area in the centre of the country. The present study aimed to etermine the validity of using presence signs in the field for discrimination of the two...
VEGETATION STRUCTURE AND COMPOSITION OF ROAD
Santos, Sara M; Mathias, Maria da Luz; Mira, António; Simões, M PaulaThis paper analyses the floristic composition and vegetation structure in road verge and meadow sites colonized by Cabrera vole (Microtus cabrerae Thomas, 1906), a threatened rodent with fragmented distribution in the Iberian Peninsula. Vegetation was sampled in 26 colonized patches in five geographical areas of Southern Portugal. The cover of the herbaceous layer was sampled in 1 × 1 m plots. Several variables...
Microtus lusitanicus (Gerbe, 1879)
Mira, António; Mathias, Maria da LuzFicha do rato-cego no Atlas e Livro Vermelho dos Mamíferos de Espanha. Inclui informação relativa à classificação, ecologia, distribuição, conservação e gestão da espécie.
Vegetation analysis in colonies of an endangered rodent
Santos, Sara M; Simões, M Paula; Mathias, Maria da Luz; Mira, AntónioThe Cabrera vole (Microtus cabrerae) is a threatened rodent endemic in the Iberian Peninsula with a patchy distribution and specific microhabitat requirements. This aim of this study was to document the composition of plant communities in habitats of Cabrera vole colonies in southern Portugal. Differences observed in plant species composition were also compared with vegetation structure, taxonomic and life form...
