Se'ns presenta una oportunitat ulllca d'aplegar en aquestes pagllles I'extensa producció escrita del Sr. Mirambell i Belloc. Des deis seus inicis professionals fins a I'actualitat com a cronista de la ciutat de Girona, ha composat pagines consagrades a temes d'actualitat social i d'ambit cultural, així com d'ambit historic i educatiu. Des d'articles de premsa fins a estudis monografics dedicats a I'ensenyament, la impremta, la Biblioteca Pública de Girona, etc.; tots ells d'un elevat valor cultural i d'una qualitat innegable. Així doncs, disposat en vuit blocs: lIibres, col'laboracions en obres col'lectives, articles en publicacions periodiques, miscel·lanies i homenatges, conferencies, comunicacions i ponencies, fultets, prolegs, epílegs i estudis introductoris i obres menors, s'ha volgut copsar tota aquesta riquesa ,-la a mans d'aquells estudiosos, investigadors i ciutadans que desitgin gaudir d'aquests textos.

If the old body is usually read as a synonym of fragility and upcoming illness, even though not the case for most elderly citizens, the reality is that the longer we live, the increased probability of being affected by different illnesses cannot be eluded or denied. In Doris Lessing’s The Diary of a Good Neighbour and Margaret Forster’s Have the Men Had Enough? the reader is invited to participate in the day-to-day routines of two aged female protagonists, as well as to empathize with their inner feelings as they go through their last life stage. In fact, their ‘dys-appearing’ bodies, marked by their respective terminal illnesses, force these characters to grow closer to those around them and to accept the help of their families and friends, despite their desire to keep their free will and independence until the very end. The analysis of the two novels within the framework of ageing studies aims to show the contradictions existing between a growing ageing society and the negative cultural connotations of old age in Western society and the need to revise them.

Comparative phylogeography seeks for commonalities in the spatial demographic history of sympatric organisms to characterize the mechanisms that shaped such patterns. The unveiling of incongruent phylogeographic patterns in co-occurring species, on the other hand, may hint to overlooked differences in their life histories or microhabitat preferences. The woodlouse-hunter spiders of the genus Dysdera have undergone a major diversi cation on the Canary Islands. The species pair Dysdera alegranzaensis and Dysdera nesiotes are endemic to the island of Lanzarote and nearby islets, where they co-occur at most of their known localities. The two species stand in sharp contrast to other sympatric endemic Dysdera in showing no evidence of somatic (non-genitalic) differentiation. Phylogenetic and population genetic analyses of mitochondrial cox1 sequences from an exhaustive sample of D. alegranzaensis and D. nesiotes specimens, and additional mitochondrial (16S, L1, nad1) and nuclear genes (28S, H3) were analysed to reveal their phylogeographic patterns and clarify their phylogenetic relationships. Relaxed molecular clock models using ve calibration points were further used to estimate divergence times between species and populations. Striking differences in phylogeography and population structure between the two species were observed. Dysdera nesiotes displayed a metapopulation-like structure, while D. alegranzaensis was characterized by a weaker geographical structure but greater genetic divergences among its main haplotype lineages, suggesting more complex population dynamics. Our study con rms that co-distributed sibling species may exhibit contrasting phylogeographic patterns in the absence of somatic differentiation. Further ecological studies, however, will be necessary to clarify whether the contrasting phylogeographies may hint at an overlooked niche partitioning between the two species. In addition, further comparisons with available phylogeographic data of other eastern Canarian Dysdera endemics con rm the key role of lava ows in structuring local populations in oceanic islands and identify localities that acted as refugia during volcanic eruptions
