AB Nowadays, functional traits are widely used to study autoecological aspectsin plant species. The analysis of these traits among climatic gradients allowsus to know the strategy that plants follow depending on resource availability.Referring to plants, the traits measured in the leaves have a special importance;among these traits we can find SLA (Specific Leaf Area), LDMC (Leaf Dry-Matter Content) and LT (Leaf Thickness). In this work, these traits are measuredin four species of the genus Asplenium. As extremes of a climatic gradient,we have focused our study in both bioclimatic regions existing in the IberianPeninsula. Taking into account the differences referring to the resourceavailability for the species in each region, the main goal of this work is analysingthe variations of the three functional traits mentioned in the four species inboth locations and associate these variations to macroclimatic variables. Tothis aim, fronds from the four species were collected in populations of eachbioclimatic region to determine the fresh weight, dry weight and the foliar area.From these variables, we calculated the three functional traits. The resultshave shown that ferns adopt higher productive yields in the Mediterraneanregion (higher SLA values) and lower LDMC and LT values than in theEurosiberian region. As to the climate variables effects, the average of themaximum temperatures in the warmest month (TMAX) is the variable thatbetter explains the differences in the productive yield that the plants adoptin each region. On the other hand, annual precipitation seems not to playan important role on any of the functional traits in any of the species. Finally,we didn’t find a generalized tendency in the effects of the extern variables:frozen period, minimum temperatures in the coolest month and arid period.
