Estudi de la variabilitat genètica de diferents poblacions europees de l'espècie Taxus baccata L. (Taxaceae) amb microsatèl·lits nuclears

Estudi realitzat a partir d’una estada a la Università degli Studi di Firenze, Itàlia, durant juliol i agost del 2007. Des de un punt de vista teòric, l’estudi de l’abundància i distribució de les espècies a escala regional és un dels objectius principals de l’ecologia de poblacions i comunitats, i és imprescindible per a adoptar polítiques de conservació i de gestió de la biodiversitat. En aquest context, la persistència i abundància de les espècies a llarg termini front al canvi global depèn de la capacitat de migració i colonització (flux gènic), i de l’ existència de potencial evolutiu a les poblacions locals per a adaptar-se als canvis ambientals. Dispersió i potencial evolutiu, es troben íntimament relacionats. El coneixement bàsic sobre aquests aspectes resulta particularment important en el context biogeogràfic mediterrani, extremadament ric en espècies i subjecte històricament a canvis ambientals com a conseqüència de l’activitat humana. L’objectiu general del nostre grup de recerca és aprofundir en el coneixement de les causes de l’àrea de distribució i del grau de fragmentació de les espècies vegetals mediterrànies, així com les seves conseqüències ecològiques i evolutives. Concretament, determinar el potencial evolutiu i la presència d’adaptacions locals en funció de la distribució geogràfica i del grau de fragmentació. En el cas del teix (T.baccata) el projecte que s’està duent a terme pretén estudiar la distribució de la diversitat genètica de l’espècie i analitzar quins són els processos històrics, evolutius i ecològics que la condicionen. És amb aquest objectiu que es vol realitzar una caracterització de la seva variabilitat genètica utilitzant marcadors moleculars basats en els polimorfismes de l'ADN nuclear, anomenats microsatèl•lits nuclears.

Estimating patterns of leaf herbivory along an altitudinal transect in NE Queensland rainforests: might global warming increase leaf herbivory in tropical rainforests?

Climate change has been taking place at unprecedented rates over the past decades. These fast alterations caused by human activities are leading to a global warming of the planet. Warmer temperatures are going to have important effects on vegetation and especially on tropical forests. Insects as well will be affected by climate change. This study tested the hypothesis that higher temperatures lead to a higher insect pressure on vegetation. Visual estimations of leaf damage were recorded and used to assess the extent of herbivory in nine 0.1ha plots along an altitudinal gradient, and therefore a temperature gradient. These estimations were made at both a community level and a species level, on 2 target species. Leaf toughness tests were performed on samples from the target species from each plot. Results showed a strong evidence of increasing insect damage along increasing temperature, with no significant effect from the leaf toughness.
