Aims: Biotic interactions may be disrupted at the range boundary if the involved species are rare in the most distant sectors. This study assesses fruit tracking by seed?dispersing birds wintering on the border of the Palaearctic, a region where[...]texto impreso
Tellería Jorge, José Luis ; Fandos Guzmán, Guillermo ; Tena López, Elena ; Carbonell Alanís, Roberto ; Onrubia, Alejandro ; Abdeljebbar, Qninba ; Ramírez García, Álvaro | Springer | 2019-03Populations at the far edges of their ranges tend to be scarce, and they are frequently of conservation concern. This paper examines the distribution of three raptors (Circaetus gallicus, Hieraaetus pennatus and Milvus migrans) at the southweste[...]texto impreso

In this context, it is important to explore the factors affecting its abundance and the ways in which it can be effectively managed for conservation. This st[...]texto impreso
This note examines the effects of habitat, landscape, climate and geographical situation on the occurrence probability of the red-backed Shrike at its westernmost range boundary. the results from 127 sampling localities distributed east-to-west [...]texto impreso
We studied the effect of climate change on the distribution of two insectivorous passerines (the meadow pipit Anthus pratensis and the chiffchaff Phylloscopus collybita) in wintering grounds of the Western Mediterranean basin. In this region, pr[...]texto impreso
En las últimas décadas se ha registrado un declive generalizado en numerosas especies de aves migratorias, lo que se ha atribuido al impacto provocado por las actividades humanas, como la pérdida de hábitat, la caza y el cambio climático. Si se[...]texto impreso
Hera Fernández, Iván de la ; Fandos Guzmán, Guillermo ; Fernández López, Javier ; Onrubia, Alejandro ; Pérez Rodríguez, Antón David ; Pérez Tris, Javier ; Tellería Jorge, José Luis | Wiley | 2018-04Mediterranean woodlands and associated shrub formations of southern Iberia are key habitats for conservation of migratory birds. In some bird species, migratory and sedentary conspecifics meet in these areas during winter, but our understanding [...]texto impreso
This paper explores the numerical trends of winter ring recoveries of the European robin Erithacus rubecula in Spain to determine whether the number of extra-Iberian individuals has decreased in recent decades. Results show that despite the incr[...]texto impreso
El anillamiento genera una información útil para predecir la distribución de las aves. En este trabajo se repasa su uso en el estudio de los paseriformes invernantes en la península Ibérica y el Magreb. Se describe, utilizando el bisbita pratens[...]texto impreso
The altitudinal distribution of species richness is affected by climate and habitat changes, and the balance between these drivers will produce an idiosyncratic pattern in each mountain range. However, the potential effect of habitat change has [...]texto impreso
Hera Fernández, Iván de la ; Hernández-Téllez, Irene ; Pérez Regueiro, José ; Pérez Tris, Javier ; Rojo, Francisco Javier ; Tellería Jorge, José Luis | Wiley | 2020-04-13Current avian migration patterns in temperate regions have been developed during the glacial retreat and subsequent colonization of the ice-free areas during the Holocene. This process resulted in a geographic gradient of greater seasonality as [...]texto impreso
Tena López, Elena ; Paz, Óscar de ; Peña, Roberto de la ; Fandos, Guillermo ; Redondo, Marisol ; Tellería Jorge, José Luis | Elsevier | 2020-06-29Gaps in the forest canopy appear to play a major role in local species richness as they increase habitat heterogeneity and border effects. In the case of bats, these small clearings seem to play an important role as foraging and commuting sites.[...]
