“…Most opossum-dispersed seeds appear to be transported only endozoochorically and chemical scarification does not usually affect their viability, neither increasing nor decreasing germination rates. Such seed types (small-sized ones) are thought to accept a wide array of dispersal agents (e.g., Bodmer, 1991;Jordano 1992). Furthermore, in Didelphis, seeds pass relatively rapid through the gut, within 4 h to 1 day, depending on the plant species (N.C. Cáceres, unpublished data).…”

“…However, under temperate conditions, seeds tend to show different germination strategies (Gómes-Pompa and Vázquez-Yanes, 1981), such as the need to undergo the low temperatures of winter in order to germinate (Metivier, 1985). Plants must be dispersed to suitable germination sites (Jordano, 1992;Schupp 1993). Among dispersal syndromes, those mediated by the wind and animals are prominent (Howe and Smallwood, 1982;Morellato et al, 2000).…”

“…All thrushes swallow the entire fruits, defecating the intact seeds in their faeces (i.e. they are legitimate seed dispersers; [31]). Other vertebrates able to disperse fleshy fruited plants in the Cantabrian Range are robin Erithacus rubecula, blackcap Sylvia atricapilla, common wood-pigeon Columba palumbus and carnivorous mammals (fox Vulpes vulpes, badger Meles meles, martens Martes spp.…”

Species richness matters for the quality of ecosystem services: a test using seed dispersal by frugivorous birds

The positive link between biodiversity and ecosystem functioning is a current paradigm in ecological science. However, little is known of how different attributes of species assemblages condition the quality of many services in real ecosystems affected by human impact. We explore the links between the attributes of a frugivore assemblage and the quantitative and qualitative components of its derived ecosystem service, seed dispersal, along a landscape-scale gradient of anthropogenic forest loss. Both the number and the richness of seeds being dispersed were positively related to frugivore abundance and richness. Seed dispersal quality, determined by the fine-scale spatial patterns of seed deposition, mostly depended on frugivore richness. In fact, richness was the only attribute of the frugivore assemblage affecting the probability of seed dispersal into deforested areas of the landscape. The positive relationships between frugivore richness per se (i.e. independent of frugivore abundance and composition) and all components of seed dispersal suggest the existence of functional complementarity and/or facilitation between frugivores. These links also point to the whole assemblage of frugivores as a conservation target, if we aim to preserve a complete seed dispersal service and, hence, the potential for vegetation regeneration and recovery, in human-impacted landscapes.

“…Pied and Spotted Flycatchers preferred Dogwood fruits during the entire stopover period every year. Gape width and fruit size are limiting factors of the first order in seed-dispersing birds that normally swallow entire fruits (Jordano 2000, Herrera 2002, Alcántara and Rey 2003, so Blackthorn and Hawthorn fruits, with a mean length and width of generally . 10 mm (Herrera 1987, Snow andSnow 1988), were only consumed by larger bird species, with high positive selection of Blackthorn fruits by Common Blackbirds and Hawthorn fruits by Song Thrushes.…”

Summer-autumn feeding ecology of Pied Flycatchers Ficedula hypolueca and Spotted Flycatchers Muscicapa striata: the importance of frugivory in a stopover area in north-west Iberia Á NGEL HERNÁ NDEZ SummaryNorth-west Iberia is a crucial stopover region for European populations of Pied Flycatchers Ficedula hypoleuca and Spotted Flycatchers Muscicapa striata during their summer-autumn migration. Both species are almost completely insectivorous during breeding in Europe and wintering in sub-Saharan Africa, but are known to consume fleshy fruits during summerautumn migration, though no detailed investigations have been carried out over long periods of time. In this study, the summer-autumn feeding ecology of Pied and Spotted Flycatchers in a stopover area in north-west Spain, with a landscape of hedgerows and irrigated meadows, was studied for five consecutive years (2002)(2003)(2004)(2005)(2006). In general, the passage of both flycatcher species was noticeable from mid-August to the end of September, with a peak in the first ten days of September. The two flycatcher species consumed fruits throughout the stopover period in all years, with constant intensity of frugivory in time, though the importance of fruits was almost three times greater in the diet of Pied Flycatchers (c. 30% of feeding acts) than in that of Spotted Flycatchers (c. 10% of feeding acts). Both species preferred Dogwood Cornus sanguinea fruits, but also ate Elder Sambucus nigra berries and Bramble Rubus spp. drupelets. The high level of selection of Dogwood fruits was probably linked to their high lipid content, an essential nutrient for fattening in long-distance migrant passerines. Hedgerows and wood edges in north-west Iberia are rich in fleshy fruits but threatened by intensive farming. Their conservation and restoration are proposed because they seem to be high-quality stopover habitats for partially frugivorous passerines during summer-autumn migration.
