Evidence of high individual variability in seed management by scatter-hoarding rodents : does 'personality' matter? / Feldman, Mariano (Centre de Recerca Ecològica i Aplicacions Forestals) ; Ferrandiz-Rovira, Mariona (Centre de Recerca Ecològica i Aplicacions Forestals) ; Espelta Morral, Josep Maria (Centre de Recerca Ecològica i Aplicacions Forestals) ; Muñoz, Alberto (Universidad Complutense de Madrid. Departamento de Didactica de las Ciencias Experimentales) ; Universitat Autònoma de Barcelona
We analysed the individual variation in behaviour by scatter-hoarding rodents. The perceived predation risk was manipulated to assess the consistency of behaviour. Individual differences explained more than 80% of total behavioural variance. [...]

13 p, 864.5 KB The avian fossil record in Insular Southeast Asia and its implications for avian biogeography and palaeoecology / Meijer, Hanneke J.M. (Institut Catala de Paleontologia Miquel Crusafont)
Excavations and studies of existing collections during the last decades have significantly increased the abundance as well as the diversity of the avian fossil record for Insular Southeast Asia. The avian fossil record covers the Eocene through the Holocene, with the majority of bird fossils Pleistocene in age. [...]

13 p, 582.3 KB Beyond predator satiation : masting but also the effects of rainfall stochasticity on weevils drive acorn predation / Espelta Morral, Josep Maria (Centre de Recerca Ecològica i Aplicacions Forestals) ; Arias-LeClaire, Harold (Centre de Recerca Ecològica i Aplicacions Forestals) ; Fernández-Martínez, Marcos (Centre de Recerca Ecològica i Aplicacions Forestals) ; Doblas Miranda, Enrique (Centre de Recerca Ecològica i Aplicacions Forestals) ; Muñoz, Alberto (Universidad Complutense de Madrid. Departamento de Didactica de las Ciencias Experimentales) ; Bonal, Raúl (Instituto de Investigación de la Dehesa)
Escaping seed predation is a classic "economy of scale" hypotheses (predator satiation hypothesis, Psh) to explain the selection for the synchronous production of massive and nil seed crops (masting) in plants. [...]

17 p, 608.9 KB Male-biased litter sex ratio in the southernmost Iberian population of edible dormouse : a strategy against isolation? / Ferrandiz-Rovira, Mariona (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Freixas, Lídia (Museu de Granollers. Àrea de Ciències Naturals) ; Torre, Ignasi (Museu de Granollers. Àrea de Ciències Naturals) ; Míguez, Sílvia (Museu de Granollers. Àrea de Ciències Naturals) ; Arrizabalaga, Antoni (Museu de Granollers. Àrea de Ciències Naturals)
Litter sex ratio is a key component of parental fitness due to its impact on lifetime reproductive success. Multiple causes may lay at the origin of sex ratio variation among species and populations, such as maternal condition, local resource competition, presence of helpers, habitat quality or inbreeding levels.

2.0 MB Endozoochory of seeds and invertebrates by migratory waterbirds in Oklahoma, USA / Green, Andy J. (Estación Biológica de Doñana (EBD-CSIC). Departmento de Ecología de Humedales) ; Frisch, Dagmar (University of Oklahoma Biological Station) ; Michot, Thomas C. (University of Louisiana. Institute for Coastal Ecology and Engineering) ; Allain, Larry K. (U.S. Geological Survey-National Wetlands Research Center) ; Barrow, Wylie C. (U.S. Geological Survey-National Wetlands Research Center)
Given their abundance and migratory behavior, waterbirds have major potential for dispersing plants and invertebrates within North America, yet their role as vectors remains poorly understood. We investigated the numbers and types of invertebrates and seeds within freshly collected faecal samples (n = 22) of migratory dabbling ducks and shorebirds in November 2008 in two parts of Lake Texoma in southern Oklahoma. [...]
Debido a su abundancia y a sus migraciones, las aves acuáticas tienen un gran potencial como dispersores de plantas e invertebrados en el Norte de América, pero su papel como vectores apenas se ha estudiado. [...]

16 p, 1.8 MB The role of new Iberian finds in understanding European Eocene mammalian paleobiogeography / Badiola Kortabitarte, Ainara (Universidad de Zaragoza. Área de Paleontología) ; Checa, Lluís (Institut Català de Paleontologia Miquel Crusafont) ; Cuesta Ruiz-Colmenares, Miguel Ángel (Universidad de Salamanca. Departamento de Geología) ; Quer, Ramón (Institut Català de Paleontologia Miquel Crusafont) ; Hooker, Jerry J. (The Natural History Museum. Palaeontology Department) ; Astibia Ayera, Humberto (Universidad del País Vasco. Departamento de Estratigrafía y Paleontología)
This paper summarizes the new Eocene mammalian discoveries in western and northeastern Iberia and analyses the paleobiological data they provide towards an understanding of the evolutionary and paleobiogeographic history of the Eocene mammalian faunas across Europe. [...]

7 p, 247.4 KB Per què hi ha formigues del Montgrí (Girona) que no es troben a l'illa Meda Gran / Espadaler, Xavier (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Suñer, David (Universitat de Girona. Laboratori de Zoologia)
Després de comparar les poblacions de formigues del Montgrí i de l'illa Meda Gran, s'intenta explicar l'absència d'algunes espècies a l'illa. El gènere Myrmica i Crematogaster scutellaris no hi troben biotops ni llocs de nidificació adequats; Aphaenogaster senilis, Cataglyphispiliscapus i Linepithema humile en serien absents a causa de la disseminació terrestre dels propàguls. [...]
After comparing the ant species from the Montgn' massif and the nearby Meda Gran island we propose some hypothesis for the absence of some species from the island. Differential colonizing capacity of propagules explains why Myrmica spp. [...]

18 p, 221.5 KB The role of alien plants in the composition of fruit-eating bird assemblages in Brazilian urban ecosystems / Guix, Juan Carlos (Universitat de Barcelona. Departament de Biología Animal (Vertebrats))
Between 1985 and 2004, 91 wild fruit-eating bird species were studied in 11 urban areas of Brazil: 78 of these species were seed dispersers and 13 were seed predators. The most representative families of fruit-eating birds in these areas were: Thraupidae with 46 species, Tyrannidae with 19 species, Psittacidae with 11 species and Turdidae with 6 species. [...]
Entre 1985 y 2004, 91 especies de aves frugívoras fueron estudiadas en 11 áreas urbanas de Brasil: 78 de estas especies eran diseminadoras de semillas y 13 eran depredadoras de semillas. Las familias de aves frugívoras más representativas en estas áreas fueron: Thraupidae, con 46 especies, Tyrannidae, con 19 especies, Psittacidae, con 11 especies y Turdidae, con 6 especies. [...]

8 p, 364.5 KB Complex plant-disperser-pest interactions in NW Amazonia : beetle larvae and companions travelling inside Attalea maripa palm nuts / Guix, Juan Carlos (Universitat de Barcelona. Departament de Biología Animal (Vertebrats))
The dispersal and predation, by vertebrates, of bruchid beetle larvae living inside Attalea maripa palm nuts are described in the region of the Middle Negro river (state of Amazonas, Brazil). The complexity of the ecological relationships between palm trees, seed dispersers, beetle seed predators and parasitic or commensal organisms is discussed and their importance to the biological diversity of the Amazonian ecosystems is argued.
Se describe la dispersión y depredación por vertebrados de larvas de coleópteros de la familia Bruchidae que viven dentro de las nueces de la palmera Attalea maripa, en la región del Medio río Negro (estado de Amazonas, Brasil). [...]
