Marine Spatial Planning (MSP) has become a priority for many states wanting to develop national blue economy plans and meet international obligations in response the increasing cumulative impacts of human activities climate change. In areas beyond jurisdiction (ABNJ), MSP is proposed as part package solutions multi-sectoral management at ocean basin scale. To facilitate planning, maps showing spatial distribution marine biological diversity are required. lacking data, like South Atlantic,...
ABSTRACT Identifying the behavioural processes influencing habitat use is important for understanding a species' and spatial ecology informing their conservation. In this study, we collected information on state of globally Near Threatened Indo‐Pacific (IP) bottlenose dolphins ( Tursiops aduncus ) inhabiting coastal waters at North West Cape (NWC), Western Australia (WA). Ensemble suitability modelling was used to identify key environmental anthropogenic variables correlated with...
The seasonal dynamics of the fish community in Pando estuary on Uruguayan coast were studied relation to environmental sampled monthly between May 2002 and June 2003. Individuals collected identified, classified into stages (juveniles, adults) functional groups. Relationships variables evaluated using uni- multivariate techniques. Twenty-one species, mostly freshwater stragglers, estuarine marine migrants collected. most abundant species Micropogonias furnieri, Mugil platanus, Paralichthys...
Abstract Information on site fidelity and ranging patterns of wild animals is critical to understand how they use their environment guide conservation management strategies. Delphinids show a wide variety patterns. Between September 2013 October 2015, we used boat‐based surveys, photographic identification, biopsy sampling, clustering analysis, geographic information systems determine the site‐fidelity representative ranges southern Australian bottlenose dolphins ( Tursiops cf. australis )...
Abstract As marine predators experience increasing anthropogenic pressures, there is an urgent need to understand their distribution and drivers inform spatial conservation planning. We used ensemble modelling approach investigate the spatio-temporal of southern Australian bottlenose dolphins ( Tursiops cf. australis ) in relation a variety ecogeographical variables Coffin Bay, Thorny Passage Marine Park, South Australia. Further, we evaluated overlap between current management measures...
Abstract This study analyses depredation by killer whales (Orcinus orca) and false (Pseudorca crassidens) on catches of the Uruguayan pelagic longline fishery in Southwestern Atlantic Ocean between 1998 2007. Data were collected scientific observers from National Observer Program Tuna Fleet operating area 19°–40.5°S 20°–54°W. Depredation occurred 67 1029 sets was restricted to 25°–40.5°S 27°–53°W, though larger proportions (DP: percentage total fish caught damaged cetaceans) observed...
The franciscana dolphin (Pontoporia blainvillei) is the most threatened small cetacean in southwestern Atlantic Ocean. Its incidental capture Uruguayan fisheries of oceanic coast (AOC) has been recorded since 1940 and was systematically studied from 1974 to 1994, providing recent by-catch per unit effort estimate (BPUE) for AOC region (0.0064 franciscanas 1000m net fishing set). lack new data during past 12 years led a gap estimates species Uruguay. current study developed two separate...
Fisheries interactions with non-target marine vertebrates are a worldwide problem.The impact of coastal bottom trawl fisheries on mammals has never been evaluated before in the Río de la Plata Estuary and adjacent Atlantic Ocean.Our aim was estimating bycatch per unit effort (BcPUE) incidental mortality rates caused by industrial fleet.We three species (i.e., franciscana dolphin Pontoporia blainvillei, South American sea lion Otaria flavescens, fur seal Arctocephalus australis); these facing...
Abstract Assessments of demographic parameters are essential to understand the dynamics wild populations, and for their efficient conservation management. Here, sex‐specific abundance, apparent survival temporary emigration southern Australian bottlenose dolphins ( Tursiops cf. australis ) in Coffin Bay (CB), South Australia, is investigated. Results based on capture–recapture modelling photo‐identification data molecular analyses biopsy samples collected during boat‐based surveys between...
Abstract Bycatch is one of the main causes human-caused mortality and population decline many marine mammals. Monitoring bycatch first step to understand impact fisheries on species affected. Understanding how interaction between mammals fishing operations varies in space time, it influenced by environmental variables, essential for designing mitigation strategies reduce mortality. In this paper, we use data gathered scientific observers a skipper analyse Uruguayan pelagic longline fishery...
Social relationships in female mammals are usually determined by an interplay among genetic, endogenous, social and ecological factors that ultimately affect their lifetime reproductive success. However, few studies have attempted to control for, integrate these factors, hampering our understanding of drivers underlying sociality. Here, we used generalized affiliation indices, combined with networks, condition, genetic data investigate associations southern Australian bottlenose dolphins....
Assessments of species distributions are crucial for informing conservation and management action. In this study, we used ensemble modelling to explain the distribution Near Threatened Indo-Pacific (IP) bottlenose dolphins ( Tursiops aduncus ) in coastal waters at North West Cape (NWC), Western Australia (WA), an area encompassing a marine protected (MPA) adjacent unprotected waters. Analyses dolphin sighting data collected during boat-based surveys conducted from 2013 2015 2018 2019....
We studied the temporal patterns of macroinfaunal distribution in estuarine portion Pando Stream, Uruguay. found a very low number species and high dominance polychaete Heteromastus similis. There were clear seasonal abundance with almost all peaking autumn, coinciding periods higher salinity. Minimal values winter spring when salinity was at minimum. suggest that pattern is consequence combined effects recruitment, osmotic stress disturbance during freshwater discharge are common spring.
Killer whale ( Orcinus orca ) is frequently encountered in coastal and high productive pelagic waters, near the shelf break. In south-western Atlantic Ocean, spatial temporal occurrence patterns are poorly known. However, monitoring of interaction between killer whales longline fishery suggests that species frequent this region. We analysed presence within Uruguayan fishing zone. Data were collected from 1996 to 2007, during 2189 events, by vessel skippers on-board observers. estimated...
Abstract Social relationships represent an adaptive behavioral strategy that can provide fitness benefits to individuals. Within mammalian societies, delphinids are known form diverse grouping patterns and show a variety of social systems. However, how ecological intrinsic factors have shaped the evolution such societies is still not well understood. In this study, we used photo-identification data biopsy samples collected between March 2013 October 2015 in Coffin Bay, heterogeneous...
Abstract The sub‐Antarctic waters of South Georgia Island (Islas Georgias del Sur, SG/IG) are a regularly visited feeding ground for southern right whales ( Eubalaena australis , SRW) in the southwest Atlantic. Satellite telemetry and photo‐identification records were compared to better understand role SG/IG SRW migratory network. We present first insights from satellite‐tracked ground, habitat use patterns Scotia Arc, movements Antarctic habitats. Photo‐identification comparisons calving...
Artisanal fisheries in Uruguay involve directly or indirectly more than 5000 people and constitute the main source of income several coastal communities.However, despite its economic environmental importance, this activity is poorly documented.As such, scarcity information constrains understanding effective management artisanal fisheries.This study aims to characterize different strategies marine on Uruguayan Atlantic coast describe spatial distribution fishing effort.Based a Principal...
Continuous measurements of environmental conditions in coastal zones are key to understanding oceanographic and atmospheric processes, as well improving our the marine environment for operational conservation purposes that can be integrated into a spatial planning process. Several efforts have been made Uruguay order achieve these goals, but they not sustained over time due high operative maintenance costs specific sensors. This work presents first results more than year continuous...
