Summary: Urbanization has a positive impact on the nesting success of Darwin's finches, but may also result in mortality due to anthropogenic factors. During dry years, urban finches build more nests, lay more eggs, and produce more fledglings compared to nonurban finches. However, urban finches' nests contain anthropogenic debris, leading to a certain percentage of nestling mortality.

Summary: Recent evidence has shown that human activities have a significant impact on species interactions and ecological dynamics. Islands, being more vulnerable to anthropogenic disturbances due to their delicate ecosystems, are particularly affected by urbanization. This study conducted in the Galapagos Islands demonstrates how early stages of urban development can alter the interactions between Darwin's finches and Tribulus cistoides, leading to changes in natural selection and community composition. Urbanization was found to result in higher rates of seed and mericarp removal, as well as differences in mericarp morphology and defensive strategies between urban and natural habitats. The findings suggest that even moderate levels of urbanization can have profound effects on species interactions and evolutionary processes in island ecosystems.

Summary: The study of biogeographic patterns in the Galapagos Islands reveals shared patterns among different groups that coincide spatially with specific tectonic structures. Research suggests that species in the Galapagos Islands may have survived by dispersing populations from older islands to new ones for colonization.

Summary: Invasive species, especially the blackberry plant, pose a significant threat to forest biodiversity, particularly on islands like the Galapagos. This study examines the impact of blackberry invasion on the decline of the green warbler finch, a unique species found in the cloud forest. The study compares the dietary changes of the finches in managed and unmanaged areas, and the results indicate that blackberry encroachment leads to a decrease in food source quality and quantity, resulting in a decline in chick recruitment.

Summary: After reviewing image plates, it was found that a misidentification occurred with an image of Rypticus subbifrenatus, which was mistakenly labeled as R. carpenter. The correction did not significantly impact the data on the ecological structure of the St. John-Thomas fauna. Additionally, an image of the blenniid fish Hypsoblennius exstochilus from St. Thomas was added to the inventory without substantial impact on the data as well.

Summary: The study focuses on the distributional biogeography of coastal fish fauna in the Socotra Archipelago and its relation to ichthyogeographic and ecoregional concepts, highlighting close affinities to a putative ecoregion in the eastern Gulf of Aden and the Arabian Sea coast of Oman. It suggests that the Socotra Archipelago should be considered a distinct ecoregion due to its unique marine diversity levels.

Summary: The study found that insectivorous and granivorous finches on Santa Cruz Island have higher δ C-13 values, while herbivorous finches have lower values. Segregation among dietary guilds was enhanced by differences in δ H-2 values, providing better trophic discrimination.

Summary: The Galapagos Islands have experienced a temperature increase of 0.6 degrees Celsius since the early 1980s, becoming drier with delayed onset of the wet season. Future climate projections suggest a potential increase in precipitation of 20-70%, along with more extreme wet and hot conditions. Regional sea surface temperatures have risen by 1.2 degrees Celsius over the last two decades, leading to potential deterioration of marine ecosystems.

Summary: The Galapagos Islands in the eastern tropical Pacific are subject to strong environmental variability. Research has shown the presence of at least 23 cetacean species, including 14 common species, in these islands. However, cetacean research in Galapagos has been sporadic and underfunded, and not considered a priority. This study identifies priorities for ecological research on cetaceans in Galapagos and recommends optimizing data sampling, incorporating citizen science activities, and involving stakeholders in the research agenda.

Summary: Recent evidence has highlighted the important role of phylogenetic history in shaping communities' response to the environment. In our study, we investigated the response of reef fish abundances to environmental variability on four oceanic islands in the southwestern Atlantic, considering phylogenetic history, functional traits, and species co-occurrence patterns. We found a strong phylogenetic signal and surface chlorophyll-a concentration to be the most important environmental factor.

Summary: Reef rugosity, a metric of three-dimensional habitat complexity, is crucial for determining reef condition and occupancy by various marine organisms. Using a new mapping technique, this study explored the variation of reef rugosity in the Main Hawaiian Islands, finding that water depth and reef slope are primary drivers of rugosity, while coastal development plays a secondary role. These results can aid in tracking geological and human impacts on reefs, designing marine managed areas, and improving reef resilience.

Summary: This study investigated the causal mechanism of the first mesopelagic fish strandings along the southeast shore of Gran Canaria Island. It was found that these strandings were mainly dominated by Diaphus dumerilli, but other Myctophidae species were also present. The study suggests that a monitoring program of coastal sites combined with satellite-derived environmental data can provide valuable information for modeling and predicting such events. The findings highlight the importance of mesoscale oceanographic structures in the occurrence of fish strandings.

Summary: Nibblers, reef fishes mostly found in the Indo-Pacific, have an interesting distribution pattern with Girella stuebeli being an exception in the Cabo Verde Archipelago in the Atlantic Ocean. Through studying genomic markers, it was discovered that G. stuebeli is closely related to a clade of three endemic species in the northwestern Pacific, diverging approximately 2.2 million years ago. The most likely migration route between these species is through the Indian Ocean and Southern Africa, based on geological history, oceanography, and molecular data analysis.

Summary: Despite increasing awareness of inclusivity, equity, and diversity issues, progress in addressing gender disparities in science and academia has been slow. This article compiles highly cited papers led by women in the Journal of Biogeography since 2009 to equalize visibility of women's influential work. By highlighting influential contributions by women biogeographers, it aims to contribute towards balancing visibility across genders and creating a greater sense of belonging for women in the field.

Summary: Genetic studies on Lessepsian bioinvaders, particularly two invasive fishes, reveal divergent patterns with little genetic structure in rabbitfish and strong population structure in filefish at the boundary of the Red Sea and the Mediterranean. Loci under selection were found in populations near the Suez Canal, suggesting the essential role of selection for successful invasions. Osmoregulation-related genes were identified, indicating their importance for individuals crossing the salinity-variable Suez Canal.

Summary: Studies on oceanic island biodiversity lay the foundation for theoretical work, while seamounts are relatively underexplored. The research suggests that seamounts play a crucial role in supporting subpopulations that eventually lead to island colonization, diversification, and a biodiversity feedback process.

Summary: The mitochondrial genome of Dascyllus trimaculatus, a planktivorous damselfish, was assembled and annotated for the first time. It is 16,967 bp in length and contains 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a control region. The gene arrangement and codon usage are similar to other damselfish genomes, and phylogenetic analysis supports known evolutionary relationships.

Summary: Surfperches are unique fishes with unresolved phylogenetic position. They are viviparous and lack a dispersive larval stage, making them an excellent model for studying speciation and local adaptation in the ocean. However, few molecular resources are available for this group. This study presents a highly complete reference genome for the kelp surfperch, which will be valuable for future research on evolutionary dynamics, local adaptation, and genomic potential for climate adaptation.

Results demonstrate that HBd can provide straightforward comparisons of network complexity and distinguish situations that are difficult to resolve with other available metrics.
