Plants dispersed by a non-frugivorous migrant change throughout the annual cycle

Renata Urgyan et al.

Summary: This study aimed to investigate how endozoochory rates change throughout the annual cycle for migratory waterfowl and how it relates to plant life-form and phenology. The results showed that migratory waterfowl endozoochory is a strong driver of plant distributions and is underestimated in its importance.

Seed Viability, Spikelet Dispersal, Seed Banks and Seed Storage Requirements for Native and Invasive Cordgrasses (Genus Spartina) in Southwest Iberian Peninsula

M. Dolores Infante-Izquierdo et al.

Summary: Seed banks play a vital role in determining the distribution of halophytes in salt marshes. We conducted experiments to test the dispersal ability and viability of Spartina maritima and S. densiflora spikelets under different environmental conditions. Our findings showed that S. densiflora spikelets had a greater ability to remain afloat and maintain viability in wet and cold conditions. Additionally, we observed that S. maritima did not establish persistent seed banks, while S. densiflora established transient seed banks mainly at higher elevations. These results provide important insights for the conservation and management of native and invasive Spartina species.

Migratory geese allow plants to disperse to cooler latitudes across the ocean

Adam Lovas-Kiss et al.

Summary: In this study, the potential of Pink-footed geese for long-distance dispersal (LDD) of flowering plants through gut passage of seeds (endozoochory) was investigated. It was found that these geese are LDD vectors for plants and can transport seeds over long distances, including across the ocean. This finding has important implications for understanding how plants can disperse and adapt to global change.

Seed Size, Not Dispersal Syndrome, Determines Potential for Spread of Ricefield Weeds by Gulls

Juan Manuel Peralta-Sanchez et al.

Summary: Recent field data suggests that migratory gulls can disperse dry fruited rice field weeds through their digestive system, providing a long-distance dispersal mechanism. In a feeding experiment, seeds of five common rice field weeds were fed to captive lesser black-backed gulls and their seed survival and germination were analyzed. The results showed high seed survival after gut passage, with varying effects on germination depending on the weed species and seed size. The study highlights the importance of non-classical endozoochory for effective weed management.

Seed dispersal by waterbirds: a mechanistic understanding by simulating avian digestion

Casper H. A. van Leeuwen et al.

Summary: Waterbirds disperse plant species through ingestion and egestion of seeds. The survival and germination of seeds are affected by mechanical digestion, seed traits such as size, hardness, imbibition, and shape. Plants growing in aquatic habitats benefit most from endozoochory by waterbirds. This information enhances our understanding of how animal species shape plant species distributions, which is extremely relevant in the face of current anthropogenic pressures.

Traits for transport: Alien wetland plants gain an advantage during endozoochorous seed dispersal by waterfowl

Adam Lovas-Kiss et al.

Summary: This study investigates the potential of alien plant seeds to disperse through ingestion, transport, and egestion in waterfowl. By comparing the endozoochorous dispersal ability of alien and native wetland plant species in a feeding experiment with mallards, it is found that alien species have higher passage rates and slower germination, while native species have shorter retention times and higher germinability. These findings suggest that alien species may have traits that facilitate successful endozoochory and enable rapid expansions in new environments.

Animal-mediated plant niche tracking in a changing climate

Tristan A. Nunez et al.

Summary: More than half of plant species rely on animals for seed dispersal, and our understanding of how animals can assist plants in responding to climate change, known as niche tracking, is limited but rapidly advancing. Recent research has provided evidence that animals play a crucial role in assisting plants to track their niches. It has identified important conditions for animal-mediated niche tracking to occur, such as synchronizing seed availability, the directionality of animal movements, and suitable microhabitat conditions for seed deposition.

Recruitment and migration patterns reveal a key role for seed banks in the meta-population dynamics of an aquatic plant

Maxi Tomowski et al.

Summary: Progressive habitat fragmentation threatens plant species with narrow habitat requirements. Dispersal is critical for population viability at the landscape scale, but is often confounded by the uncertainty about soil-stored population compartments. The study analyzed the genetic structure of Oenanthe aquatica populations and their soil seed banks to uncover hidden connectivity among populations in time and space. Results indicate stepping-stone dispersal across adjacent populations and suggest the importance of persistent seed banks as enduring sources of genetic diversity.

EuDiS-A comprehensive database of the seed dispersal syndromes of the European flora

Pablo Vargas et al.

Summary: Seed dispersal is important for plant colonization and demography. Traits favoring dispersal by a specific vector have been considered as seed dispersal syndromes, and have attracted the attention of naturalists and researchers. However, confusion still exists in distinguishing between seed dispersal syndromes and actual seed dispersal, which prevents a comprehensive understanding of seed dispersal mechanisms.

Functional Traits Drive Dispersal Interactions Between European Waterfowl and Seeds

Bia A. Almeida et al.

Summary: Endozoochory by waterfowl is important for a broad range of angiosperms, most of which lack a fleshy fruit. This dispersal function contributes to the formation and maintenance of plant communities and may allow range shifts for plant species under global change. However, our current understanding of what seed or plant traits are important for this dispersal mechanism, and how they relate to variation in waterbird traits, is extremely limited.

Plant dispersal syndromes are unreliable, especially for predicting zoochory and long-distance dispersal

Andy J. Green et al.

Summary: Plant dispersal syndromes are often used to predict dominant dispersal mechanisms, but the classical syndromes may not accurately reflect the actual dispersal events. Endozoochory and epizoochory syndromes may not be helpful in predicting which plants non-frugivores disperse, or by which mechanism, and more empirical research is needed to understand the relationship between plant traits and dispersal mechanisms.

Endozoochory of the same community of plants lacking fleshy fruits by storks and gulls

Victor Martin-Velez et al.

Summary: Research on the dispersal of plants lacking fleshy fruit by avian endozoochory is limited. This study compared plants dispersed by two different migratory waterbirds and found overlap in the communities of non-fleshy-fruited plants dispersed by the birds. The study also revealed that avian vectors provide greater dispersal distances than predicted from their dispersal syndromes for some plant species.

Ongoing anthropogenic eutrophication of the catchment area threatens the Donana World Heritage Site (South-west Spain)

Irene Paredes et al.

Summary: Eutrophication is a major issue in wetlands globally, with nutrient pollution impacting water quality in the Donana wetland complex in SW Spain. Research shows that nutrient concentrations in the streams feeding the marsh are consistently high, particularly due to greenhouse expansion. The wetland, currently relied upon for water purification, requires urgent reinforcement of policies to reduce nutrient inputs for biodiversity conservation and environmental objectives.

Spatial patterns of weed dispersal by wintering gulls within and beyond an agricultural landscape

Victor Martin-Velez et al.

Summary: Non-frugivorous waterbirds play a crucial role in dispersing weed plants over long distances, exchanging species between human-dominated and natural areas. The study demonstrates that about 92% of weed seeds are dispersed within the birds' activity area, while the remaining 8% reach other habitats, with 42% reaching moist environments suitable for weed establishment. This research emphasizes the significance of non-frugivorous birds in long-distance plant dispersal, an often overlooked mechanism in weed plant expansion studies.
