Dear colleagues, on behalf of my co-authors, I am pleased to share two of our recent publications on the bottlenose dolphin population inhabiting the Tiber River estuary area (the "Capitoline Dolphins"). Labriola, M. S., Parisi, A., Marinchel, N., Rinalduzzi, S., Turchi, A., Giacomini, G., Pace, D.S. & Russo, T. (2026). *Fishing trawlers drive the fine-scale daytime distribution of bottlenose dolphins at the Tiber River estuary (Western Mediterranean Sea)*. *Marine Environmental Research*, 107996. https://doi.org/10.1016/j.marenvres.2026.107996 ABSTRACT Fisheries can strongly alter marine ecosystem dynamics, influencing the ecology and behaviour of top predators such as cetaceans. At the Tiber River estuary (Tyrrhenian Sea, Western Mediterranean), bottlenose dolphins (Tursiops truncatus) frequently interact with bottom trawlers operating off the coast of Rome. We combined five years (2019-2023) of boat-based survey data with fishing data derived from the Vessel Monitoring System (VMS) to assess the influence of trawling activity on dolphin distribution. Spatial and temporal correlations between dolphin presence and fishing effort were analysed using multivariate analysis and overlap metrics. Dolphin occurrence was modelled relative to environmental and vessel-level predictors with generalized linear mixed-effects models (GLMMs), incorporating chlorophyll-a concentration (concurrent and lagged) as a proxy for productivity. In the area where sufficient survey effort was invested, dolphin presence was strongly associated with fishing hotspots, and dolphins shifted farther offshore on trawling days, indicating an ecological switch from nearshore natural resources to trawler-associated prey. Spatial overlap varied markedly among vessels, indicating preferences for certain trawlers. GLMMs identified specific vessels with a significant positive effect on dolphin occurrence, even after controlling for productivity. Catch analysis revealed these vessels landed higher amounts of European hake and common octopus, key dolphin prey species. Findings suggest dolphins exhibit flexible, and possibly socially acquired, foraging strategies in response to fisheries, with trawling acting as a strong driver of their distribution. While adaptive, such associations may reduce natural foraging, alter ecological dynamics, and pose conservation issues. This study provides a fine-scale perspective of fishery-driven behavioural change in dolphins and offers actionable insights for local management under EU marine biodiversity directives. Mattiussi, A., Labriola, M. S., Turchi, A., Rinalduzzi, S., Giacomini, G., Pedrazzi, G., & Pace, D. S. (2026). *Uplifting resources management in conservation: mid-term studies are able to capture the dynamic patterns of site-fidelity and seasonal abundance of coastal cetacean populations*. *Hydrobiologia*, 1-18. https://doi.org/10.1007/s10750-026-06141-y ABSTRACT Mid-to long-term research is pivotal for conservation and coastal management yet often undervalued by policymakers and funding bodies. Continuous marine monitoring may be needed to define animal residency patterns and abundance—key information for effective conservation strategies. Here, we used an eight-year (2016–2023) dataset on coastal bottlenose dolphins at Tiber River estuary (Mediterranean Sea, Italy) to examine site-fidelity and estimate population abundance. The work aimed to (1) compare results with a previous, shorter-term study (2017–2020) and (2) test whether extended datasets enhance understanding of population dynamics. Longitudinal photo-identification analysis and site-fidelity metrics (occurrence, monthly/yearly rates, resight rate, periodicity, relative span-time) confirmed three site-fidelity clusters: residents, partially-residents and transients. A first-order Markov chain model revealed a high misclassification risk for partially-residents in short-term studies. Kernel density estimations showed distinct spatial use, with a more coastal occurrence of residents. The updated abundance estimate aligns with previous findings but with a narrowed confidence interval, indicating population stability and improved statistical robustness. These results support the need of multi-year studies for reliable ecological insights and population assessments. We urge policymakers to support longer-term research efforts and consider our findings in future local conservation actions targeting coastal dolphins, key species in marine ecosystems. The first paper is available as open access, whereas the second is not. However, I would be very happy to share a copy upon request; please feel free to get in touch if you are interested. I hope these contributions may be of interest, and I would greatly appreciate any feedback or discussion.
