Institute of Statistics) ; Colwell, Robert K. (University of Connecticut. Department of Ecology and Evolutionary Biology)
In the context of capture-recapture studies, Chao (1987) derived an inequality among capture frequency counts to obtain a lower bound for the size of a population based on individuals' capture/non-capture records for multiple capture occasions. [...]

21 p, 963.6 KB PYCNOIB : Biodiversity and Biogeography of Iberian Pycnogonids / Soler Membrives, Anna (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Munilla León, Tomás (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Biodiversity and biogeographic studies comparing the distribution patterns of benthic marine organisms across the Iberian Atlantic and Mediterranean waters are scarce. The Pycnogonida (sea spiders) are a clear example of both endemicity and diversity, and are considered a key taxon to study and monitor biogeographic and biodiversity patterns. [...]

Department of Special Botany and Functional Biodiversity)
Future global change scenarios predict a dramatic loss of biodiversity for many regions in the world, potentially reducing the resistance and resilience of ecosystem functions. Once before, during Plio-Pleistocene glaciations, harsher climatic conditions in Europe as compared to North America led to a more depauperate tree flora. [...]

La pèrdua, fragmentació i transformació dels hàbitats representen una gran amenaça per a la biodiversitat en els ecosistemes terrestres d'arreu del món, desencadenant tant extincions com colonitzacions amb un resultat incert en la composició i la riquesa d'espècies. [...]
Habitat loss, fragmentation and transformation are major threats for biodiversity in terrestrial ecosystems worldwide, driving both species extinctions and colonisations with an uncertain outcome on species composition and richness. [...]

36 p, 229.4 KB Diversity of pyrrolizidine alkaloids in native and invasive Senecio pterophorus (Asteraceae) : Implications for toxicity / Castells, Eva (Universitat Autònoma de Barcelona. Departament de Farmacologia, de Terapèutica i de Toxicologia) ; Mulder, Patrick P. J. ; Pérez-Trujillo, Míriam (Universitat Autònoma de Barcelona. Servei de Ressonància Magnètica Nuclear)
Changes in plant chemical defenses after invasion could have consequences on the invaded ecosystems by modifying the interactions between plants and herbivores and facilitating invasion success. However, no comprehensive biogeographical studies have yet determined the phenotypic levels of plant chemical defenses, as consumed by local herbivores, covering large distributional areas of a species.

Este trabajo estudia la presencia y complejidad en el tratamiento del concepto de diversidad biológica en libros de texto de educación secundaria, tanto de la obligatoria (ESO) como del bachillerato de España. [...]
Aquest treball estudia la presència i complexitat en el tractament del concepte de diversitat biològica en llibres de text d'educació secundària, tant de l'obligatòria (ESO) com del batxillerat d'Espanya. [...]
This paper studies the existence and complexity of the treatment of the biodiversity concept in middle and high school Spanish textbooks. Scientific papers from the «expert community» were reviewed in order to define the biodiversity conceptual framework, which acts as the epistemological vigilance during the process of didactic transposition.

11 p, 214.6 KB Experimental evidence of reduced diversity of seedlings due to climate modification in a Mediterranean-type community / Lloret Maya, Francisco (Universitat Autònoma de Barcelona.

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Estiarte, Marc (Centre de Recerca Ecològica i d'Aplicacions Forestals)
We are still lacking in experimental evidence of the effects of climate change on the richness of plant species under field conditions. We report a decrease in the species richness of recruited seedlings in a Mediterranean shrubland in experimentally induced drought and warming over 4 consecutive years. [...]
