Increases in leaf mass per area (LMA) are commonly observed in response to environmental stresses and are achieved through increases in leaf thickness and/or leaf density. Here, we investigated how the two underlying components of LMA differ in relation to species native climates and phylogeny, across deciduous and evergreen species. Using a phylogenetic approach, we quantified anatomical, compositional and climatic variables from 40 deciduous and 45 evergreen Quercus species from across the Northern Hemisphere growing in a common garden. Deciduous species from shorter growing seasons tended to have leaves with lower LMA and leaf thickness than those from longer growing seasons, while the opposite pattern was found for evergreens. For both habits, LMA and thickness increased in arid environments. However, this shift was associated with increased leaf density in evergreens but reduced density in deciduous species. Deciduous and evergreen oaks showed fundamental leaf morphological differences that revealed a diverse adaptive response. While LMA in deciduous species may have diversified in tight coordination with thickness mainly modulated by aridity, diversification of LMA within evergreens appears to be dependent on the infrageneric group, with diversification in leaf thickness modulated by both aridity and cold, while diversification in leaf density is only modulated by aridity.
espanolEl presente trabajo se centra en la aportacion del naturalista y botanico sueco Perh Loefling (1729-1756) en el conocimiento de la flora de Extremadura fruto de su itinerario por territorio extremeno en octubre de 1751.A traves de la consulta de diversas fuentes documentales digitalizadas [archivos, bibliotecas, herbarios (LINN, S-LINN, H, SBT), etc.] se obtiene informacion sobre las aportaciones a la diversidad floristica extremena y su contribucion a la descripcion de nuevas especies botanicas en el siglo XVIII. El trabajo se apoya parcialmente en la transcripcion de numerosos manuscritos en los que se detalla las recolecciones o envios de plantas de origen extremeno a Linneo, su maestro, y sus companeros y amigos en Suecia. Buena parte de las transcripciones de esos manuscritos se adicionan al trabajo como apendices. Finalmente se aporta un listado de especies indicadas o referenciadas por Loe-fling para territorio extremeno con indicacion de la fuente documental de origen EnglishThe present work focuses on the contribution of the Swedish naturalist and botanist Perh Loefling (1729-1756) to the knowledge of the flora of Ex-tremadura as a result of his itinerary through the territory in October 1751.Through consultation of diverse digitized documentary sources [ar-chives, libraries, herbariums (LINN, S-LINN, H, SBT), etc.] information is obtained on the knowledge of the floral diversity of Extremadura and its con-tribution to the description of new botanical species in the 18th century. The work is partly based on the transcription of numerous manuscripts detailing the collections or shipments of plants from Extremaduran to Linnaeus, his teacher, and his companions and friends in Sweden. Much of the transcriptions of these manuscripts are added to work as appendices. Finally, a list of species indicated or referred to by Loefling for Extremadura territory is provided, with an indication of the original documentary source
espanolEn el presente estudio se pone de manifiesto la presencia de al menos 61 especies vegetales representadas en los tapices flamencos conservados en la Catedral de Badajoz, titulados “Fidelidad de Penelope”. Las especies vegetales se analizan en relacion a su presencia, disposicion en los tapices y se contrasta con estudios previos. El resultado es un listado de 360 especies vegetales que han aparecido en los tapices flamencos de los siglos XV-XVII (Apendice II). El analisis fenologico de los motivos indica que las escenas se desarrollaban durante la primavera-verano, no existiendo coincidencia plena en el estado fenologico de las especies vegetales representadas. EnglishIn the present study highlights the presence of at least 61 plant species represented in the Cathedral of Badajoz Flemish tapestries, titled “Fidelity of Penelope”. Plant species discussed in relation to its presence, available at tapestries and contrasts with previous studies. The result is a checklist of 360 plant species that have appeared in Flemish tapestries them from the 15th-17th centuries (Appendix II). Motives phenological analysis indicates that the scenes were developed during the spring and summer; there is no full coincidence in the phenological period.
