Rapid changes in the environment and climate, today more pronounced than ever, affect their fitness and distribution causing rapid species declines, sometimes even before they had been discovered. Despite the high goals set by conservationists to protect native plants from further degradation and extinction, the initiatives for the conservation of threatened species in Europe are scattered and have not yielded the desired results. The main aim of this Action is to improve plant conservation in Europe through the establishment of a network of scientists and other stakeholders who deal with different aspects of plant conservation, from plant taxonomy, ecology, conservation genetics, conservation physiology and reproductive biology to protected area's managers, not forgetting social scientists, who are crucial when dealing with the general public.

[CBNPMP-Thématique] Système de reproductionMots-clés : Salvia verbenaca L. Résumé : Variation in fruit set, seed/ovule ratio and mean single-seed weight among plants, and within plants among inflorescences, was investigated in a population of Salvia verbenaca in northwest Spain. Mean single-seed weight varied significantly among plants which flowered at about the same time and mean single-seed weight was significantly greater for plants that flowered late in the season than for plants flowering early in the season. Within individual plants, mean single-seed weight increased steadily between the earlier opening basal inflorescences and the later opening upper inflorescences. However, neither fruit set nor seed/ovule ratio varied significantly among inflorescences. Previous work on this population indicates that outcrossing improves mean single-seed weight, so I suggest that the observed pattern of among-inflorescence variation in mean single-seed weight may be attributable to a gradual increase in nonself pollen receipt as the flowering season progresses.

Titre : Fruit-set and seed weight variation in Anthyllis vulneraria subsp. vulgaris (Fabaceae) Type de document : Tiré à part de revue Auteurs : Luis Navarro Année de publication : 1996 Importance : 139-148 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Stratégie de production de semences (fécondité) Mots-clés : Anthyllis vulneraria L. ssp. vulgaris (Koch) Corb. Résumé : Fruit-set and seed weight variation was studied in a population ofAnthyllis vulneraria subsp.vulgaris (Fabaceae) in northwestern Spain. The plants produce several shoots, each bearing two to four inflorescences that open one at a time from bottom to top. Fruit-set, seed-pod weight and seed weight were found to be significantly higher in proximal inflorescences than in distal inflorescences of the same shoot; mean seed weight was up to three times higher in proximal than in distal inflorescences. By contrast, none of the three variables varied significantly among plants or among shoots of the same plant. Similarly, none of the three variables differed significantly between early- and late-flowering plants, or between plants monitored in 1993 and in 1994. These results are compatible with the view that shoots function as semiautonomous units as regards resource allocation, and that within the shoot resources are preferentially allocated to proximal (= early-opening) inflorescences. In the plants studied, the ratio of seed-pod weight to seed weight was fairly constant, suggesting that the pod is important for seed success.

Titre : Is the dichogamy of Salvia verbenaca (Lamiaceae) an effective barrier to self-fertilization? Type de document : Tiré à part de revue Auteurs : Luis Navarro Année de publication : 1997 Importance : 111-117 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Régime et stratégie de reproduction (allogamie, autogamie, apomixie, reproduction asexué)
[CBNPMP-Thématique] Système de reproductionMots-clés : Salvia verbenaca L. Résumé : Though dichogamy is generally interpreted as a means of preventing self-fertilization, the efficiency of this mechanism has been questioned. Little attention has been paid to functional aspects of male/female timing, such as variation over time in pollen germinability and in stigma receptivity. In the present study these aspects of male/female timing were investigated in the protandrous speciesSalvia verbenaca. To evaluate the effects of selfing, fruit set, total seed weight produced and seed/ovule ratio were also determined, (a) following artificial crossing, (b) following selfing (i.e. bagging) and (c) under natural conditions. Both pollen germinability and stigma receptivity peaked on the last day (day 3) of the flower's life, which presumably favours selfing. Neither fruit set nor seed/ovule ratio were significantly affected by pollination regime, but the total seed weight produced by artificially crossed plants was significantly higher than that produced by bagged or untreated plants. Neither fruit set, seed/ovule ratio nor total seed weight differed significantly between the two years of study. Thus, if aS. verbenaca flower receives outcrossing pollen it will produce a greater weight of seeds (with consequent advantages in terms of female reproductive success). However, the peaking of both pollen germinability and stigma receptivity on day 3 of the flower's life means that selfing is likely to occur if outcrossing pollen has not been received over the early part of the flower's life.

Titre : Pollination ecology of Anthyllis vulneraria subsp. Vulgaris (Fabaceae) : nectar robbers as pollinators Type de document : Tiré à part de revue Auteurs : Luis Navarro Année de publication : 2000 Importance : 980-985 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Coadaptation, coévolution, symbiose (dissémination, pollinisation)
[CBNPMP-Thématique] Système de reproductionMots-clés : Anthyllis vulneraria L. ssp. Vulgaris (Koch) Willk. Résumé : This paper examines the hypothesis that nectar robbing can affect plant reproductive success either positively or negatively. To this end, I investigated various aspects of the pollination ecology of a population of the herb Anthyllis vulneraria subsp. vulgaris in northwest Spain over 5 yr. By observing floral visitors, I found that the most important pollinator species was the long-tongued bee Anthophora acervorum, which accounted for ∼45% of recorded insect visits. However, just over 45% of visits were by the nectar-robbing bumble bees Bombus terrestris and B. jonellus. Although the incidence of robbing differed considerably over 5 yr of study, the frequency in every season was very high (66.4–76.5% of robbing) except for 1997 (0% robbing). Despite this high frequency of robbing, robbed flowers had a higher probability of setting fruit than nonrobbed flowers in all years of the study (mean: 82.0 vs. 51.0%; excluding 1997). This increased fruit set in robbed flowers is directly related to bumble bee behavior because the robbers' bodies came into contact with both the anthers and stigmas while robbing. Thus, the robbers effect pollination. These results suggest that the effect of nectar robbers on plant reproductive success is dependent both on the robbers' behavior and on flower/inflorescence structure. The importance of nectar-robbing bumble bees on the reproductive success of A. vulneraria and its yearly high frequency suggest that the relationship between robbers and this plant is part of a successful long-term mutualism.
