Special Issue Information

Dear Colleagues,

This issue is dedicated to investigating the complex and vital relationships that define the ecological integrity of freshwater, marsh, coastal, and artificial wetlands. In an era marked by rapid environmental change, the preservation and understanding of these ecosystems have become increasingly critical.

The background for this research is rooted in the profound alterations our planet is undergoing. Global change, encompassing climate shifts, pollution, and habitat degradation, coupled with direct human interventions, is reshaping the very fabric of wetland ecosystems. Issues such as eutrophication, salt stress, the proliferation of antibiotic resistance genes, and the pervasive presence of microplastics are posing unprecedented challenges to wetland biodiversity.

The significance of this research lies in its potential to elucidate the consequences of these environmental pressures on the structure and function of wetland ecosystems. By focusing on the responses and ecological roles of key species or groups—whether they are native dominants, invasive species, or those facing the threat of extinction—we aim to uncover the mechanisms driving changes in biodiversity patterns. This knowledge is essential for developing effective conservation strategies and management practices that can sustain wetland ecosystems in the face of ongoing global and anthropogenic disturbances.

This Special Issue seeks to contribute to the growing body of knowledge on wetland ecosystems by addressing the following themes:

  • The impact of global change and anthropogenic disturbances on wetland biodiversity and ecosystem services.
  • The ecological and evolutionary responses of key species or groups to environmental stressors.
  • The role of invasive species and biological invasions in altering wetland community dynamics.
  • The conservation challenges and opportunities in the context of changing wetland landscapes.

We invite you to join us in this important endeavor by submitting your research findings and insights to this Special Issue. Together, we can advance our understanding of wetland ecosystems and their conservation in the face of a rapidly changing world.

Warm regards,

Wetlands are crucial ecosystems that provide a wide range of ecological services, such as water purification, flood control, and carbon sequestration, where the diversity of wetland plants is fundamental to maintaining these functions. Phragmites australis is a globally widespread wetland grass with a high genetic diversity, exhibiting strong intraspecific variation across environmental gradients. While both phenotypic plasticity and genetic variation are recognized drivers of plant adaptation, their relative importance in mediating the growth and decomposition traits of wetland plants remains debated. Here, we surveyed the growth and litter traits of two lineages (haplotypes) of P. australis in two common gardens in eastern China. The leaf litter of P. australis was also collected from the field in two provinces where the two common gardens are located. Microcosm experiments were carried out to explore the litter decomposition ability. We found that the common garden (growth environment) significantly affected the growth performance (shoot diameter and height), leaf litter stoichiometric traits (contents of N and P), and the leaf decomposition over 180 days. The N content in the leaf litter from the higher-latitude province of Liaoning was greater than that from the lower-latitude province of Shandong, regardless of whether it was collected from the field or the common garden. The litter N and P contents were the key factors affecting the decomposition during the 180-day experiment. However, we did not find the effects of lineage (genetic variation) on the variation of these traits. The climatic factors of the genotype origin were significantly correlated with the growth traits but not the litter traits or decomposition rates. The findings indicate that P. australis in eastern temperate China primarily adapts through phenotypic plasticity rather than genetic variation, which is crucial for wetland resilience in a changing climate. This study underscores the pivotal role of environmental factors and phenotypic plasticity in P. australis growth and decomposition, suggesting that conservation efforts should prioritize the local environment over genetic variation for effective wetland management.
