Special Issue Information

Dear Colleagues,

The marine biosphere harbors an extraordinary diversity of life, intricate ecological interactions, and essential ecosystem services that support global environmental and human well-being. However, accelerating biodiversity loss, climate change, habitat degradation, and anthropogenic pressures threaten the integrity of marine ecosystems worldwide. This Special Issue invites original research, reviews, and methodological advances that investigate the structure and function of marine biodiversity across spatial and temporal scales. We seek contributions exploring organism–environment interactions, food web dynamics, functional diversity, the role and effectiveness of marine protected areas (MPAs), habitat restoration, and ecological resilience under scenarios of global change. Particular emphasis is placed on interdisciplinary studies that integrate biological, ecological, and conservation perspectives. Submissions focusing on a wide range of marine environments—from coastal zones to the deep sea—are welcome. Research that highlights the importance of biodiversity in sustaining ocean health and informs adaptive management strategies will be prioritized. By gathering diverse insights into the ecological roles of marine organisms and the mechanisms that sustain ecosystem functioning, this issue aims to promote science-based approaches to marine conservation and to contribute to building more resilient seas in the Anthropocene.

The critically endangered Kemp’s ridley sea turtle (Lepidochelys kempii) population experienced a catastrophic decline from a peak in 1947 to a low in 1985, followed by exponential growth prior to 2010. However, the Deepwater Horizon (DWH) oil spill caused a demographic setback. Monitoring nesting female straight carapace length (SCL) is crucial for assessing population structure and recovery. We analyzed interannual variation in SCL of nesting females at Rancho Nuevo Sanctuary, Tamaulipas, Mexico, during the 2018–2023 nesting seasons. A total of 191 females were measured, and a comprehensive statistical analysis was performed to validate the use of parametric tests. One-way ANOVA revealed significant differences in mean SCL among years (p < 0.001). The lowest seasonal SCL means were in 2020 (59.01 ± 1.79 cm) and 2022 (60.68 ± 1.47 cm), while the highest SCL means occurred in 2018 (62.77 ± 1.81 cm), 2019 (62.01 ± 1.56 cm), 2021 (62.19 ± 1.47 cm), and 2023 (61.75 ± 2.07 cm). There was no significant linear decline in mean SCL from 2018 to 2023 (p = 0.78). These results suggest short-term interannual variability rather than a consistent shift in body size structure, providing updated baseline information for post-DWH population monitoring and future recruitment assessments.
