Despite the fact that parrots (Psitacifformes) are generalist apex frugivores, they have largely been considered plant antagonists and thus neglected as seed dispersers of their food plants. Internal dispersal was investigated by searching for seeds in faeces opportunistically collected at communal roosts, foraging sites nests eleven parrot species different habitats biomes Neotropics. Multiple intact seven five families were found a variable proportion from four species. The mean number...
Mediterranean shrublands are generally water-limited and fire-driven ecosystems. Seed-based post-fire regeneration may be affected by varying rainfall patterns, depending on species sensitivity to germinate under water stress. In our study, we considered the germination response stress in four from several sites across Basin. Seeds of with a hard coat (Cistus monspeliensis, C. salviifolius, Cistaceae, Calicotome villosa, Fabaceae) or soft (Erica arborea, Ericaceae), which were exposed not...
Background: Species of the Cistaceae family have hard-coated seeds and consequently require scarification for germination. It is widely assumed that high temperature caused by fire a scarifying agent triggers seed germination in Cistaceae. However, to date there insufficient knowledge regarding species, populations diverse variables associated with consider such trigger generally applicable.Aims: To test relationship between exposure 10 species family.Methods: We quantified after different...
Species differ in their temperature germination niche. Populations of a species may similarly across the distribution range species. Anticipating impacts climate variability and change requires understanding differential sensitivity to among within Here we studied responses four hard-seeded Cistaceae seeders current future temperatures.Seeds were collected at sites Iberian Peninsula exposed or not heat shock break dormancy, then set germinate under regimes. Temperatures varied daily...
Abstract In seasonal climates, germination timing is mainly controlled by temperature, especially in species with physiological seed dormancy. The response to temperature may, however, vary among populations across the distribution range of species. Understanding how along climate gradients their sensitivity important for determining vulnerability variability and change. Here, we investigated two Erica dormancy ( E. australis umbellata ) changes throughout seasons (simulated autumn through...
Abstract Water availability regulates timing of germination, especially in those environments where it is a limiting factor. However, the water requirements for germination most wild Mediterranean species are unknown. In this work we analysed response to stress eight Cistaceae with hard-coated seeds, which typical shrublands. Seeds were exposed heat shock order overcome physical dormancy and then incubated under five potentials (0, −0.2, −0.4, −0.6 −0.8 MPa). Ungerminated seeds following...
Abstract Aims Seed dispersal by endozoochory is an important process in plant regeneration and the establishment of new populations. Seeds with dormancy may especially benefit after disperser gut passage. However, ways which passage affect germination species physiological remain unclear. Here, we experimentally assessed mutualistic interaction between Austral parakeet (Enicognathus ferrugineus) as a calafate (Berberis microphylla), thorny bush inhabiting understory temperate forests South...
Abstract Establishing whether herb seed endozoochory is accidental or has evolved independently in combination with other dispersal mechanisms may be valuable the study of plant–animal interactions, but it remains unexplored for birds. We tested an Australian cockatoo, galah ( Eolophus roseicapilla ), swallows entire seeds when feeding on tissues without subsequent digestion, thus enhancing (the ‘foliage fruit’ hypothesis). Our preliminary sampling provides strong evidence supporting that...
Abstract In the intricate web of plant–animal interactions, granivore birds can play a dual antagonist–mutualist role as seed predators and dispersers. This study delves into ecological significance house sparrow ( Passer domesticus ) disperser by endozoochory. A sample individual droppings faecal pools were collected from communal roost in central Spain to examine presence seeds. Seed viability was determined using tetrazolium test. Our findings revealed that around 22% analysed contained...
Understanding of ecosystem structure and functioning requires detailed knowledge about plant–animal interactions, especially when keystone species are involved. The recent consideration parrots as legitimate seed dispersers has widened the range mechanisms influencing life cycle many plant species. We examined interactions between burrowing parrot Cyanoliseus patagonus two dominant algarrobo trees (Prosopis alba Prosopis nigra) in Monte Desert, Argentina. recorded abundance foraging...
Extreme drought events during post-fire regeneration are becoming increasingly frequent in Mediterranean-type ecosystems. Understanding how plants with different traits and origins respond to such conditions early life stages is therefore critical for assessing the effect of climate change. Here, seedlings three Cistus (semi-deciduous malacophylls from Mediterranean Basin) Ceanothus (evergreen sclerophylls California) species, two seeder genera contrasting leaf traits, were subjected...
