Summary: The western conifer seed bug population has rapidly expanded in the southern peninsula of Korea since 2010. Two types of human-mediated passive movements, traffic effects and forest-product transportation, were used to model the population advancement. A lattice structure model and a spatial network model were developed to simulate the natural population dynamics of the pest and its passive movement through forest-product transportation. The simulation results matched the observed data, showing rapid expansion of the pest population across the nation within 10 years.

Summary: This study quantifies the joint effects of seed traits and phylogeny on species distribution and finds that seed mass, seed dispersal mode, and phylogeny significantly influence species geographic distribution. The findings highlight the importance of including seed traits and phylogenetic history in climate-based niche models to predict the response of plant geographic distribution to climate change.

Summary: Most terrestrial plants disperse by seeds, but the relationship between seed traits and plant dispersion patterns is not well understood. This study examined seed traits of 48 plant species in western Montana grasslands to investigate this relationship. It was found that larger-seeded introduced plants were more likely to have dispersal adaptations, suggesting that they may need these adaptations to overcome limitations and barriers. Database seed masses correlated with local estimates, but locally collected data provided more valid results for community-level questions.

Summary: Seed shattering is a natural phenomenon in wild and weedy plant species, controlled by genetics but influenced by environmental conditions and management practices. While undesirable in domesticated crops, it serves as a crucial survival mechanism for weeds, aiding in efficient seed dispersal and soil seedbank development. Weed species have evolved variations in seed shattering as an adaptation to changing management regimes, presenting challenges for agricultural weed management but also opportunities for innovative approaches such as harvest weed seed control.

Summary: This study found that the seeds of Eleocharis acuta and Eleocharis sphacelata germinated best on moist soil and when inundated, exhibited buoyancy for dispersal, and showed dormancy characteristics. These germination and dispersal traits define the establishment of these species in relation to hydrological variability.

Summary: Aquatic plants employ diverse reproductive strategies, including sexual and asexual reproduction, to adapt to different environments. In dryland river systems, floodplain inundation is infrequent and unstable, prompting the plants to rely on long-distance dispersal, seed longevity, self-fertilisation, and vegetative growth for persistence. This study investigated the reproductive proportions and genetic structure of two aquatic plants in a floodplain in western New South Wales, Australia, revealing the importance of floodplain inundation in promoting seed germination, establishment, and reproduction in dryland regions.

Summary: The dispersal-syndrome hypothesis suggests that fruit traits are shaped by selection from frugivores. Recent studies have shown that fruit nutrient content plays a key role in determining mutualistic relationships between plants and seed dispersers, with bird-dispersed fruits being richer in lipids and mixed-dispersed fruits having higher vitamin C content.

Summary: Seed rain is crucial for forest recovery, but seed viability has been overlooked in most studies. The study found that seed viability was higher in burned plots than in control plots, which may be attributed to the functional traits of the seeds.

Summary: Seed dispersal by ants is crucial for plant migration, with elaiosomes providing nutritional rewards. However, some seeds without elaiosomes are also dispersed by ants, suggesting additional mechanisms. Research on Monotropastrum humile seeds demonstrated that volatile odors can induce ant-mediated seed dispersal, even in the absence of elaiosomes.

Summary: This study assessed the impact of changes in seed and pollen dispersal on the genetic variability of an isolated population of Caryocar brasiliense. The results showed that populations with well preserved pollinators had lower rates of inbreeding and maintained greater genetic diversity over time, while reductions in pollen dispersal distance or pollination efficiency led to increased inbreeding and decreased genetic diversity. Conservation strategies should consider both tree and pollinator protection.

Summary: Zoonotic diseases, such as avian influenza, pose a significant threat to human population and food security. This study used GPS telemetry data to track the movement patterns of wild waterfowl near commercial livestock facilities in Washington and California. The research found that wild ducks frequently used the facilities and nearby wetlands for roosting and foraging, and demonstrated high site fidelity and strong connectivity with surrounding wetlands.

Summary: Karyotypes of Cuscuta plants exhibit high diversity in terms of chromosome number and genome size. The prevalent evolutionary processes in this genus include genome duplications and dysploidy. The expansion of genome size in Cuscuta may be associated with its parasitic lifestyle. The position of rDNA sites varies, especially in species with multiple sites in the same karyotype.

Summary: Existing international frameworks and policies for bird conservation focus more on individual sites rather than the network and connectivity between sites. We propose a three-step quantitative approach to protect bird movement connectivity from a network perspective. This approach can serve as a tool for comprehensive and dynamic monitoring of site network robustness.

Summary: Many angiosperms rely on vertebrates for seed dispersal via gut passage. The seed dispersal effectiveness (SDE) framework provides a method to evaluate animal-mediated seed dispersal. We propose an extended SDE framework ('eSDE') that allows comparing effectiveness among different types of plant-disperser interactions, and provide recommendations for standardized data collection protocols.

Summary: Anthropogenic resource subsidization has led to an increase in generalist avian predators, particularly ravens, which can negatively impact species like the sage-grouse. This study examined the spatiotemporal patterns of raven density and evaluated the nest success of sage-grouse in relation to fluctuating raven densities. The researchers developed a spatially explicit decision support tool to guide management actions in areas where sage-grouse nests are at highest risk of failure.
