Chamaerops humilis L. (Mediterranean dwarf palm) is an important floristic element of the western Mediterranean region because it is the only palm species naturally distributed in both Europe and Africa. The combination of a time-calibrated phylogeny, a haplotype network and genetic diversity analyses based on plastid sequences, together with previous nuclear DNA fingerprint results, helped reconstruct the colonization history of the dwarf palm. Based on a sample of 218 individuals taken from 29 geographical areas that cover the current distribution of Chamaerops, we detected four plastid DNA (petA-psbJ) haplotypes distributed in two haplotype groups (lineage 1: haplotypes A/B; lineage 2: haplotypes C/D). Haplotypes A, B, and C showed a widespread geographical distribution in both Africa and Europe, whereas haplotype D was restricted to two African localities. Paleobotanical data, species distribution modeling and divergence time estimates suggest that Chamaerops diverged from Trachycarpus in the Miocene (27.05-6.05 Ma), followed by a split of the two C. humilis lineages that remained isolated during the Miocene-Pliocene. Divergence estimates also support a derived split into two haplotypes (A/B) in the Pleistocene, when the Mediterranean Sea barrier was in existence. This, together with geographical distribution of haplotypes A and B, strongly suggests that the disjunct distribution of C. humilis haplotypes in Europe and Africa is the result of long-distance dispersal (LDD) events rather than vicariance. In agreement with recurrent gene flow (events of LDD colonization), AMOVA revealed that most of the genetic variance was found among populations (61.52%). Irrespective of predominant plant translocations by humans or seed dispersal by natural means, our results support that current populations are the result of relatively recent contacts between Africa and Europe in the Quaternary.

Assessing the relative importance of nurse species on Mediterranean human-altered areas

Pedro J. Garrote, Antonio R. Castilla, Jose M. Fedriani

Summary: One advantageous strategy for landscape restoration is the use of nurse plants, with a study showing that a Mediterranean endemic palm is the most important nurse species. This species can promote spatial associations with late-successional plant species and save additional resources.

Summary: This study investigates the role of nurse-beneficiary plant interactions in the success of revegetation projects, showing that shifts in plant-plant interactions can affect plant recruitment and performance. The study also highlights the strong inter-individual variation in these interactions and proposes management recommendations to increase plant recruitment and project success.

Predation risk can modify the foraging behaviour of frugivorous carnivores: Implications of rewilding apex predators for plant-animal mutualisms

Summary: The presence of apex predators can have significant impacts on food webs, affecting the abundance and foraging behavior of frugivorous carnivores, as well as seed dispersal and the demography of fleshy-fruited plant species. Understanding these ecological interactions is crucial for designing effective conservation strategies, particularly in rewilding programs.

Summary: Plant-animal interactions have a wide range of effects on plant reproductive success. This study examines the isolated and joint effects of two introduced herbivores on pollinator abundance and plant reproductive success in the Mediterranean dwarf palm.

Spatial isolation impacts pollinator visitation and reproductive success of a threatened self-incompatible Mediterranean tree

M. Teresa Alonso-Lopez, Pedro J. Garrote, Jose M. Fedriani

Summary: The spatial distribution of individuals has important effects on the reproduction of self-incompatible trees, with higher conspecific density resulting in competition for pollinators. However, trees close to flowering conspecifics have higher fruit set despite receiving fewer visits from pollinators, indicating pollen limitation rather than pollinator limitation. Additionally, spatially isolated trees have higher crop sizes, which may be attributed to reduced competition for resources and higher reproductive investment.

Unmasking the perching effect of the pioneer Mediterranean dwarf palm Chamaerops humilis L.

Victor Gonzalez-Garcia, Pedro J. Garrote, Jose M. Fedriani

Summary: Although farmlands are the most extensive terrestrial biomes, the abandonment of traditional agriculture has created opportunities and challenges for the restoration of human-disturbed habitats. This study found that the spatial distribution of perch plants affects the seed arrival via frugivorous birds, with isolated plants receiving more bird feces and dispersed seeds. These findings provide valuable insights for the restoration of disturbed habitats.

Spatiotemporal Effects of Free-Roaming Horses on White-Tailed Deer Distribution in Northwestern Costa Rica

Summary: The study examines the spatial and temporal interactions between white-tailed deer and horses in Costa Rica. The results suggest that white-tailed deer prefer areas with horses and habitats such as grassland and shrubland. Although there is a high degree of overlap in activity patterns between horses and white-tailed deer, the presence of horses does not negatively affect the spatiotemporal activity of white-tailed deer.

From seed dispersal service to reproductive collapse: density-dependent outcome of a palm-mammal interaction

Raquel Munoz-Gallego, Thorsten Wiegand, Anna Traveset, Jose M. Fedriani

Summary: This study investigates the interaction between Mediterranean palm and feral goat, and finds that the intensity of goat activity affects palm distribution, seed rain, and seed predation. In areas with low goat activity, seeds are spatially aggregated around adult palms but experience higher insect-seed predation and lower seed germination success. In areas with high goat activity, palm seed dispersal and recruitment are almost non-existent due to heavy consumption by goats. The study shows how the outcome of plant-animal interactions can vary from mutualism to antagonism and even reproductive collapse depending on species abundance and activity.

Seedling responses to moderate and severe herbivory: a field-clipping experiment with a keystone Mediterranean palm

P. J. Garrote, M. N. Bugalho, J. M. Fedriani

Summary: This study investigates the effects of plant intrinsic and extrinsic factors on plant-ungulate interactions in Mediterranean ecosystems. The results suggest that severe clipping and seedling aging decrease seedling survival, while moderate clipping has no effect. Nurse shrubs play a role in increasing seedling size and improving survival. The study emphasizes the importance of managing severe herbivory and summer droughts to protect plant communities.
