Summary: The study examines the population genetics and connectivity of H. laauense in the North Pacific. The results show low heterozygosity, moderate genetic structuring among populations, and inconsistent connectivity between locations. These findings suggest a mixed pattern of connectivity, likely influenced by the patchy distributions of the corals.

Summary: The geomorphology of coastal lagoons plays a crucial role in the hydrological balance and biogeochemical properties. This study found that seasonal variations in suspended particulate organic matter (POM) in different lagoon systems were influenced by environmental variability driven by hydrological dynamics. The differences in environmental conditions resulted in significant variations in POM composition between the two lagoon systems.

Summary: The rapid expansion of avocado cultivation in Michoacan, Mexico, leads to deforestation. In this study, we assessed the fragmentation and connectivity of temperate forests in the Avocado Belt and identified the patches that contribute most to connectivity. We updated land-use maps using satellite imagery and found that temperate forests in the region are highly fragmented and have low connectivity, especially in terms of seed dispersal. The conservation and management strategies should focus on the identified patches that support seed connectivity, which are found within denser zones of avocado orchards.

Summary: This study investigates the connectivity patterns of two closely related newt species using genomic data and tools from landscape genetics. The results show that forest habitat is important for connectivity in both species, but they differ in their use of forested habitat. Anthropogenic landscapes increase resistance in both species, but have a stronger effect on the range-restricted species.

Summary: Beneficial relationships between animals and microbial organisms (symbionts) are common in nature. The composition of microbial symbionts in the ocean is shaped by adaptation to local habitat conditions. We compared the symbiont population structure between deep-sea hydrothermal vent mussels and co-occurring snail species and found differences in geographical partitioning and evidence for environmental adaptation. The feeding mode and habitat stability may influence the selection of symbiont strains. These findings contribute to our understanding of symbiont population structure in marine environmentally transmitted symbioses.

Summary: Wetlands are important for biodiversity and ecosystem services. Human activities have led to global wetland decline, but created wetlands can help counteract this loss. Fish and amphibians coexist in created wetlands, with certain differences in species occurrence and interactions. Additional habitat heterogeneity can enable the coexistence of these taxa.

Summary: The study found that female House Wrens typically disperse over longer distances than males, especially at local spatial scales; however, long-distance dispersal is rare at broader spatial scales. Genetic analyses revealed that while female populations separated by long distances show slight but significant genotypic differences among them, male populations exhibit genetic differences at even greater distances.

Summary: Evidence suggests that soil fungal richness along elevational gradients is highly variable, with different patterns observed for saprotrophic and ectomycorrhizal fungi. Soil properties, climate, and plant communities directly or indirectly influence total and saprotrophic fungal richness, while ectomycorrhizal fungal richness is affected by climate and the dominance of ectomycorrhizal trees. Source-sink dynamics lead to opposite elevational patterns between saprotrophic and ectomycorrhizal fungal richness, shaping the variation in elevational richness gradients.

Summary: Understanding connectivity patterns among remote atoll reefs is crucial for managing fishery target species. This study compared the population genomics of two sympatric species of coral trout within and between three isolated offshore atoll reef systems in north-western Australia. The results indicate high levels of connectivity within reef systems and limited connectivity between reef systems, suggesting that biological stocks primarily occur at the scale of each reef system.

Summary: The study focused on mapping phylogenetic turnover patterns of reptiles and amphibians in the Cerrado savannas of South America and found that geographical distance is the key factor explaining phylogenetic turnover in reptiles. Climatic variables and relief roughness were more important for endemic reptiles and amphibians. Incongruence in phylogenetic turnover between reptiles and amphibians suggests different responses to geographical and environmental gradients.

Summary: This study investigates the genome-wide differentiation patterns in the ectomycorrhizal porcini mushroom, Boletus edulis, a globally distributed species complex. The study reveals contrasting patterns of genomic divergence between continents, with multiple lineages present across North America, while a single lineage dominates Europe. These geographical lineages are inferred to have diverged around 1.62-2.66 million years ago. Despite evidence of substantial and ongoing introgression, high levels of genomic differentiation were observed among lineages. The study emphasizes the importance of local adaptation and environmentally mediated divergence in fungal population differentiation.

Summary: In this paper, the influence of the distributed delay on the stability and spatiotemporal dynamics in the memory-based diffusion single population model is investigated. It is shown that the weak kernel does not affect the stability of the positive constant steady state, but for the strong kernel, the combined effect of diffusion rate and distributed delay can lead to rich dynamics. The theoretical conditions for stability, Hopf bifurcation, and double Hopf bifurcation are explicitly determined for the strong kernel.

Summary: Genomic analysis revealed that maerl beds of P. calcareum in the north-east Atlantic are geographically structured due to limited dispersal potential and connectivity. Unique genetic diversity of P. calcareum in the Fal Estuary, south-west England, was shaped by geographical isolation and lack of gene flow with other populations, separate from closely related species. Preserving the accumulated genetic diversity of P. calcareum is crucial for enhancing resilience to climate and environmental changes, requiring conservation management at a site-by-site level in western Europe.

Summary: This study investigates the contribution of a stocking programme to sea trout population in the Shetland Islands, and found that despite extensive stocking, wild spawned brown trout still dominated, indicating a very limited impact of stocking. The revival of sea trout numbers appears to be driven almost exclusively by recovery of trout spawned in the wild.

Summary: A study on the genetic diversity and population structure of Gray's beaked whales in the Southern Hemisphere found high levels of mtDNA diversity, stable demographic history, and no geographic structure. An increase in female effective population size approximately 250 thousand years ago coincided with enhanced Southern Ocean productivity, sea surface temperature, and potential habitat expansion. These findings suggest that Gray's beaked whales are resilient to future ecosystem changes.

Summary: Effective management of Atlantic salmon requires accurate assessment of stock compliance within individual rivers. Key metrics for assessing compliance include the number of adult female spawners and their egg deposition rates. However, current methods often underestimate the proportion of female salmon, leading to consistent underestimation of egg deposition rates. By using non-invasive sampling and genetic sex testing, this study found that phenotypic-based sexing of Tamar salmon was unreliable, especially for early run fish.

Summary: This study compares the genetic structure of European clawed lobster and European crawfish in order to identify the factors shaping population connectivity in species with shared spatial ranges and ecological niches. The results show higher levels of differentiation in clawed lobsters compared to crawfish, and suggest that hydrographic and topographic barriers play a role in generating patterns of divergence. These findings have important implications for the conservation and sustainable management of these ecologically and economically significant crustaceans.
