Temporal variation of wing geometry in Aedes albopictus

Although native to the tropical and subtropical areas of Southeast Asia, Aedes albopictus is now found on five continents, primarily due to its great capacity to adapt to different environments. This species is considered a secondary vector of dengue virus in several countries. Wing geometric morphometrics is widely used to furnish morphological markers for the characterisation and identification of species of medical importance and for the assessment of population dynamics. In this work, we investigated the metric differentiation of the wings of Ae. albopictus samples collected over a four-year period (2007-2010) in São Paulo, Brazil. Wing size significantly decreased during this period for both sexes and the wing shape also changed over time, with the wing shapes of males showing greater differences after 2008 and those of females differing more after 2009. Given that the wings play sex-specific roles, these findings suggest that the males and females could be affected by differential evolutionary pressures. Consistent with this hypothesis, a sexually dimorphic pattern was detected and quantified: the females were larger than the males (with respect to the mean) and had a distinct wing shape, regardless of allometric effects. In conclusion, wing alterations, particularly those involving shape, are a sensitive indicator of microevolutionary processes in this species.

Monitorización de estructuras y gestión de edificios: Building Management

El objetivo del proyecto es realizar un sistema de monitorizacion de estructuras y gestión de edificios para controlar en todo momento el estado de los mismos. Se controlará cualquier aspecto que pueda afectar al edificio, como es la temperatura, la humedad, la oscilación del edificio; además de otros aspectos que ayuden a que el edificio se mantenga seguro y en perfecto estado como alarmas de seguridad, luminosidad, etc.

In memoriam: Dr. Francesc Abel i Fabre, SJ.

The Journal of Medicine and Philosophy has been impoverished by the loss of Dr. Francesc Abel Fabre, S.J. (1933–2011), one of the founders of bioethics and a long-time member of the Editorial Advisory Board. 2011 brought the death of Dr. Francesc Abel Fabre, S.J., at the age of 78. He was the pioneer of European bioethics. Dr. Abel learned the discipline at Georgetown University, working side by side with the founder and first director of the Kennedy Institute of Ethics, André Hellegers, as bioethics itself was coming into existence. He went from this experience to establish the Institute Borja of Bioethics in Catalonia in 1976, the first center of bioethics in Spain and in Europe. Through his scholarship and teaching, he established an influential dialogue in bioethics, as well as ethics committees in hospitals and in research centers. In 1986 he joined in founding the European Association of Centres of Medical Ethics, an organization in which he was involved and participated for the last 25 years. He contributed crucially to bioethics across the world, especially through the International Study Group on Bioethics (1980–1994). He was widely recognized as an outstanding bioethics expert in Latin America.
