Strong inbreeding depression and individually variable mating system in the narrow endemic Erodium cazorlanum (Geraniaceae) Acusada depresión por endogamia y sistema reproductivo variable entre individuos en una especie endémica estricta, Erodium cazorlanum (Geraniaceae)

Description: Angiosperms evolved different systems to attract effective pollinators while reducing selfing in hermaphroditic flowers. Selfing ability can be advantageous when pollinators and/or mates are scarce, although inbreeding depression may largely reduce those advantages. Recent comparative analyses sugge...

Phylogenetic context of reproductive system evolution in subdioecious Daphe laureola

Description: Recent phylogenetic analyses of sexual reproductive systems supported the evolutionary pathway from hermaphroditism to dioecy via gynodioecy in different groups of angiosperms. In this study, we explore the evolution of sexual reproductive systems in Daphne laureola L. (Thymelaeaceae), a species ...

Patterns made of patterns: variation and covariation of leaf nutrient concentrations within and between populations of Prunus mahaleb

Description: • Patterns of within and between population variation in concentrations of nutrients (N, P, K, Ca, Na, Mg, Cu, Fe, Mn, Zn) are reported in mature leaves of individual Prunus mahaleb (Rosaceae) trees from five south-eastern Spanish populations. • MANOVA and canonical discriminant analysis were used t...

Neither vegetative nor reproductive advantages account for high frequency of male-steriles in Southern spanish Gynodioecious Daphne laureola (Thymelaeaceae)

Description: In gynodioecious species, male-steriles (termed ‘‘females’’ hereafter) usually exhibit some reproductive advantage over hermaph- rodites that allow them to compensate for the loss of male reproductive function. This compensation can result from higher fecundity, vegetative outperformance, and/or low...

Seasonal variation in leaf characteristics and food selection by larval noctuids on an evergreen Mediterranean shrub

Description: — Despite year round availability of foliage, abundance of generalist noctuid larvae (Lepidoptera: Noctuidae) in evergreen- dominated Mediterranean forests has a narrow, distinct spring peak. This restricted larval period has been suggested to result in part from avoidance of the ...

Variation in herbivory within and among plants of Daphne laureola (Thymelaeaceae): correlation with plant size and architecture

Description: 1 Herbivory by noctuid moth larvae (Lepidoptera, Noctuidae) on plants of Daphne laureola L. (Thymelaeaceae) was studied under natural conditions in a south-eastern Spanish montane habitat. The main objective of the study was to determine how size and architectural features correlated with ...

Developmental and spatial covariation of nutrients in growing leaves of Daphne laureola and their relationships with herbivory

Description: • Here, we studied patterns of covariation of 10 leaf nutrients in expanding and mature leaves of the evergreen shrub Daphne laureola (Thymelaeaceae) in southern Spain. Changes in mean values and covariances of nutrients during leaf develop- ment may be relevant for plant fitness through herbivory i...

Back-and-Forth hermaphroditism: phylogenetic context of reproductive system evolution in subdioecious Daphne laureola

Description: Recent phylogenetic analyses of sexual reproductive systems supported the evolutionary pathway from hermaphroditism to dioecy via gynodioecy in different groups of angiosperms. In this study, we explore the evolution of sexual reproductive systems in Daphne laureola L. (Thymelaeaceae), a species ...

Strong inbreeding depression and individually variable mating system in the narrow endemic Erodium cazorlanum (Geraniaceae)

Description: [ES]Las Angiospermas han desarrollado diversos sistemas para atraer polinizadores eficientes y al mismo tiempo reducir la posibilidad de autopolinización asociada al hermafroditismo. La capacidad de autopolinización puede ser ventajosa en situaciones de escasez de polinizadores y/o individuos reprod...
