Context Gaining insights into seasonal aggregations of marine megafauna and how patterns vary among demographic groups is pivotal for evaluating anthropogenic risk exposure modeling populations ecosystem dynamics. In California, adult subadult white sharks recurrently aggregate on the coast near pinniped colonies in fall winter months, facilitating comprehensive long-term field studies. Aims this study, we used over 15 years passive acoustic telemetry data to compare dynamics coastal habitat use tagged central California four (adult females, males, males). Methods Acoustic tags were deployed 355 at aggregation sites monitored across a array underwater receivers from 2006 2022. The main Northeast Pacific (Año Nuevo, Farallon Islands Tomales) continuously monitored, with an expansion network south latter study. Key results White tracked average duration 594 ± 552 days (mean s.d.), total track durations ranging up 3235 days. Notably, male exhibited highest residency demonstrated earlier peak densities late October. Adult female presence peaked early December. displayed distinct gaps detection where they have been shown satellite migrate offshore, females displaying much longer than males (averaging 1.5 vs 0.7 years). contrast, subadults higher affinity more consistent widespread detections number throughout year, often extending beyond areas outside season. Conclusions We hypothesize that observed differences between are attributed sex- size-specific foraging reproductive strategies. extended receiver also showed expansive movements identified potential undescribed sites.

Knowledge of the three-dimensional movement patterns elasmobranchs is vital to understand their ecological roles and exposure anthropogenic pressures. To date, comparative studies among species at global scales have mostly focused on horizontal movements. Our study addresses knowledge gap vertical movements by compiling first synthesis habitat use from data obtained deployment 989 biotelemetry tags 38 elasmobranch species. Elasmobranchs displayed high intra- interspecific variability in patterns. Substantial overlap was observed for many epipelagic elasmobranchs, indicating an increased likelihood display spatial overlap, biologically interact, share similar risk threats that vary a gradient. We highlight critical next steps toward incorporating into management monitoring strategies emphasizing need address geographic taxonomic biases deployments concurrently consider both

Floods are one of the most often occurring and damaging natural hazards. They impact society on a massive scale result in significant damages. To reduce floods, needs to keep benefiting from latest technological innovations. Drones equipped with sensors algorithms (e.g., computer vision deep learning) have emerged as potential platform which may be useful for flood monitoring, mapping detection activities more efficient way than current practice. better understand scope recent trends domain drones management, we performed detailed bibliometric analysis. The intent performing analysis waws highlight important research trends, co-occurrence relationships patterns inform new researchers this domain. was terms performance (i.e., publication statistics, citations top publishing countries, journals, institutions, publishers Web Science (WoS) categories) science by country, keyword co-occurrences, co-authorship, co-citations bibliographic coupling) total 569 records extracted WoS duration 2000–2022.

Abstract Aquaculture contributes a significant portion of the global aquatic biomass destined for human consumption. Bivalve and marine finfish aquaculture operations require sea‐based farm sites that result in considerable interactions with natural environment. The addition feed waste physical structures (e.g., net pens longline mussel culture) can provide an attractive artificial reef many species studies have shown both positive negative effects on surrounding ecosystem due to wild sites. Assessing these be complex, depending local ecosystem, several monitoring techniques been used accurately determine associations decapods farms. In this review, we assessed main methods monitor aquaculture‐ecosystem interactions. advantages disadvantages each technique are discussed suggestions mitigate shortfalls future outlined. It was evident combining methodologies should prioritised lessen impact identified weaknesses any given approach. Designing complementary approaches may help attain robust data further understand underlying proximate mechanisms.

Ocean biodiversity loss is being driven by several anthropogenic threats and significant efforts are required to halt losses promote healthy marine ecosystems. The establishment of a network Marine Protected Areas (MPAs) can help restrict damaging activities have been recognised as potential solution aid conservation. When managed correctly they deliver both ecological socio-economic benefits. In recent times, MPA designations increased rapidly while many countries set future targets for the decades ahead. An integral element management adequate monitoring that collects data assess if conservation objectives achieved. Data acquired vary widely techniques employed collect such data. Ideally, non-destructive non-invasive methods preferred prevent damage habitats species, though this may rule out number traditional extractive sampling approaches dredges trawls. Moreover, advances in ocean observation technologies enable collection large amounts at high resolutions, automated processing beginning make analyses more logistically feasible less time-consuming. Therefore, developments existing new emerging led diverse array options when choosing implement an programme. Here, we present review non-extractive which be applied monitoring.
