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

Raquel Munoz-Gallego et al.

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.

Recruitment facilitation in expanding forests of Mediterranean juniper is sex-biased

Irene Martin-Fores et al.

Summary: Despite concerns about global deforestation rates, forests in Europe have expanded due to rural exodus and abandonment of agrarian practices. The recruitment of Spanish junipers in expanding forests is influenced by conspecific adult size and heterospecific woody vegetation, with saplings associated with male adults at the expanding front. The study highlights the importance of management measures in recently colonized areas for forest restoration in extreme environments, aligning with biodiversity policies.

Eradication of feral goats, not population control, as a strategy to conserve plant communities on Mediterranean islets

Miquel Capo et al.

Summary: The introduction of mammalian herbivores negatively affects insular vegetation. Eradication programs are crucial for the recovery of plant diversity and species vulnerable to herbivory. This study evaluated vegetation recovery on Es Vedr`a island after a reduction in the feral goat population, finding significant improvements in plant communities and functional traits. However, negative effects reappeared when the goat population increased, highlighting the importance of absolute eradication for ecological restoration.

Spatial patterns in neighbourhood effects on woody plant selection and bark stripping by deer in a lowland alluvial forest

Jan Holik et al.

Summary: This study examines how woody plant interactions at different spatial scales modify deer herbivory, and finds that neighbourhood effects mainly arise from interactions between neighbouring shrub species and all tree species, as well as interactions between individual species pairs. These effects more often increase than reduce the stripping of focal individuals.

Effects of sexual dimorphism on pollinator behaviour in a dioecious species

Laura Moquet et al.

Summary: The study found that flower number dimorphism negatively affected the number of visits on female plants and flowers, but did not impact the number of pollen grains deposited per stigma. Meanwhile, flower size dimorphism had no effect on visitation patterns and pollen transfer.

Strongly unbalanced gender attractiveness in a dioecious mass flowering tropical tree pollinated by stingless bees

P. Calaca et al.

Summary: This study investigates the dioecious Myracrodruon urundeuva tree species and finds that male and female flowers offer different quantities and qualities of floral resources. Male trees produce more flowers, and female flowers open in the afternoon with a fruit-set rate of 27%. Besides a few effective pollinators, many bees are only found on male flowers.

New Evidence Suggests No Sex Bias in Herbivory or Plant Defense

Risa D. Sargent et al.

Summary: Dioecious plants can exhibit sexual dimorphism in various traits, including susceptibility to herbivory and secondary chemistry. Previous studies have found male-biased herbivory, but recent reviews have questioned the generalizability of this pattern. This meta-analysis of 71 dioecious plant species found no consistent difference between male and female plants in secondary chemistry and a directionally similar, although not statistically significant, male bias in herbivory compared to earlier studies.

Nonadditive effects of two contrasting introduced herbivores on the reproduction of a pollination-specialized palm

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.

The Eurasian badger-generated seed rain drives the natural (re)colonization of vacant human-altered areas by a keystone pioneer palm

Pedro J. Garrote et al.

Summary: Seed dispersal is crucial for plant (re)colonization in human-altered habitats, and understanding the spatial patterns and mechanisms of dispersal is essential. A study in southwestern Spain found that the Eurasian badger plays a central role in the seed dispersal and colonization of Mediterranean old-fields. The study also revealed variations in the strength and scale of spatial associations between mammal feces, plant seeds, and adult plants, providing evidence for both density-dependent mortality effects and facilitative effects.

Differential reward in male versus female pollen of functionally dioecious Solanum

Jackie R. Ndem-Galbert et al.

Summary: The study compared protein and amino acid content of porate pollen from male flowers and inaperturate pollen from functionally female flowers of two functionally dioecious Australian species. It found that porate pollen grains from staminate flowers had higher levels of proteins and amino acids compared to inaperturate pollen grains from functionally female flowers. Additionally, the andromonoecious species showed the highest levels of proteins and amino acids in pollen from bisexual and staminate flowers.

Neighbourhood effects modify deer herbivory on tree seedlings

Jan Holik et al.

Summary: The study found that the neighbourhood effects can modify deer foraging behavior depending on the proximity, density, and species identity of neighbours, thereby influencing the strength and spatial extent of browsing impacts on tree seedlings. Different tree species and seedling sizes affect deer selectivity at different spatial scales.

Large mammalian herbivores contribute to conspecific negative density dependence in a temperate forest

Stephen J. Murphy et al.

Summary: The Janzen-Connell Hypothesis predicts that natural enemies limit the population sizes of abundant species, maintaining local community diversity. This study found that large mammalian herbivores can drive conspecific negative density dependence in temperate tree seedlings. Further research on large mammals in other systems is important for understanding forest diversity maintenance globally.

Mildly toxic shrubs as indicators of goats herbivory give information for the management of natural landscapes on Mediterranean islands

Miquel Capo et al.

Summary: The predation impact of feral goats on the shrub Euphorbia dendroides was assessed on Mallorca Island, indicating that the population structure of the shrub changed with the presence of feral goats. Euphorbia dendroides could be used as an ecological indicator to determine the extent of ungulate damage to vegetation or indicate poor food availability, informing the maintenance of optimal animal populations.

Sexual differences and sex ratios of dioecious plants under stressful environments

Summary: Dioecious plants exhibit sexual dimorphism in both sexual features and secondary sex characteristics. Responses to stress may vary between sexes depending on species and stress types, highlighting the need for further research on dioecious plant species to generalize stress effects.
