Despite the long evolutionary history of this group, challenges brought by Anthropocene have been inflicting an extensive pressure over sharks and their relatives. Overexploitation has driving a worldwide decline in elasmobranch populations, rapid environmental change, triggered anthropogenic activities, may further test group's resilience. In context, we searched literature for peer-reviewed studies featuring sustained (>24 h) controlled exposure species to warming, acidification,...
The northeast Atlantic Ocean contains multiple habitats considered critical for shark conservation, including nursery areas, migratory corridors and aggregation sites. In this context, updating knowledge on diversity the threats affecting them in region is essential to defining priorities implementing right management conservation measures. Here, we show that Macaronesian Cabo Verde marine ecoregions are home 78 species (comprising 26 families), 56% threatened with extinction. Canary Islands...
Seahorses are currently facing great challenges in the wild, including habitat degradation and overexploitation, how they will endure additional stress from rapid climate change has yet to be determined. Unlike most fishes, poor swimming skills of seahorses, along with ecological biological constraints their unique lifestyle, place weight on physiological ability cope changes. In present study, we evaluate effects ocean warming (+4°C) acidification (ΔpH = −0.5 units) behavioural ecology...
Introduction Historically considered to be a single cosmopolitan species, the so called Octopus vulgaris species complex (OVSC) is now recognized group of (at least) six cryptic species: O. americanus (in west Atlantic), northeast Atlantic and Mediterranean Sea), aff . region South Africa), tetricus (southeastern Oceania), sinensis (northwestern Pacific), djinda (western Australia). The potentially different environmental preferences this highly may result in distinct consequences under...
Advances in ocean observing technologies and modeling provide the capacity to revolutionize management of living marine resources. While traditional fisheries approaches like single-species stock assessments are still common, a global effort is underway adopt ecosystem-based (EBFM) approaches. These consider changes physical environment interactions between ecosystem elements, including human uses, holistically. For example, integrated aim synthesize suite observations (physical, biological,...
Coastal areas host some of the planet’s most productive ecosystems, providing life-sustaining ecological services and several benefits to humankind, while also being threatened (e.g., by globalization, climate change, biological invasion). Salt marshes are coastal habitats with a key role in food shelter provisioning, sediment deposition, nutrient cycling carbon storage. Spartina spp. is genus grass halophytes which occurs salt worldwide, includes species different invasive potential. We...
Synopsis Aside from being one of the most fascinating groups marine organisms, cephalopods play a major role in food webs, both as predators and prey, while representing key living economic assets, namely for artisanal subsistence fisheries worldwide. Recent research suggests that are benefitting ongoing environmental changes overfishing certain fish stocks (i.e., their and/or competitors), putting forward hypothesis this group may be few “winners” climate change. While many meta-analyses...
Few animal groups can claim the level of wonder that cephalopods instill in minds researchers and general public. Much cephalopod biology, however, remains unexplored: largest invertebrate brain, difficult husbandry conditions, complex (meta-)genomes, among many other things, have hindered progress addressing key questions. However, recent technological advancements sequencing, imaging, genetic manipulation opened new avenues for exploring biology these extraordinary animals. The molecular...
Sharks have maintained a key role in marine food webs for 400 million years and across varying physicochemical contexts, suggesting plasticity to environmental change. In this study, we investigated the biochemical effects of ocean acidification (OA) levels predicted 2100 (pCO2 ~ 900 μatm) on newly hatched tropical whitespotted bamboo sharks (Chiloscyllium plagiosum). Specifically, measured lipid, protein, DNA damage levels, as well changes activity antioxidant enzymes non-enzymatic ROS...
This study describes the first potential multi-species shark nursery area in Atlantic Africa (Sal Rei Bay – SRB, Boa Vista Island, Cabo Verde). From August 2016 to September 2019, 6162 neonates and juveniles of 5 different species were observed SRB using beach gillnet-based bycatch surveys, namely milk ( Rhizoprionodon acutus ; n= 4908), scalloped hammerhead Sphyrna lewini 1035), blacktip Carcharhinus limbatus n=115), weasel Paragaleus pectoralis 93) nurse Ginglymostoma cirratum 12) sharks....
Abstract In a digital era where terabytes of structured and unstructured records are created stored every minute, the importance collecting small amounts high quality data is often undervalued. However, this activity plays critical role in industrial laboratory settings, when addressing problems from process modeling analysis, to optimization robust design. Implementing screening design usually way begin systematic statistical Design Experiments program. Its aim find influential factors...
Abstract Climate change is expected to have major negative effects on marine life across phylogenetic groups. Cephalopods, however, history characteristics that suggest they may benefit from certain climate scenarios. Of all cephalopods, squids reach the greatest biomasses; as a result, are of substantial importance for human and predator consumption. To test hypothesis beneficial commercial squid, we used species distribution models scenarios period between 2000 2014, well years 2050 2100...
Marine heatwaves (MHWs) have recently been proposed to be more relevant in driving population changes than the continuous increase average temperatures associated with climate change. The causal processes underpinning MHW effects sharks are unclear but may linked fitness caused by physiological trade-offs that influence immune response. Considering scarcity of data about response under anomalous warming events, present study analyzed several indices and characterized (in blood, epigonal...
The dramatic decline of European eel ( Anguilla anguilla) populations over recent decades has attracted considerable attention and concern. Furthermore, little is known about the sensitivity early stages eels to projected future environmental change. Here, we investigated, for first time, potential combined effects ocean warming (OW; Δ + 4°C; 18°C) acidification (OA; - 0.4 pH units) on survival migratory behaviour A. anguilla glass eels, namely their preference towards riverine cues...
As Earth's temperature continues to rise, sudden warming events, designated as marine heatwaves (MHWs), are becoming more frequent and longer. This phenomenon is already shown significantly impact ecosystems respective fauna. While experimental acclimation higher temperatures known affect predatory behavior, metabolism overall fitness of sharks, the effects short-term exposure high on sharks' physiology has yet be investigated in a MHW context. Thus, aim our work was study category II (Δ3...
Sao Tome and Principe (STP) is a small island developing state in the Gulf of Guinea (West Africa) considered global hotspot marine biodiversity. Still, detailed information on sharks' diversity, abundance, respective fisheries mainly absent. Here, we interviewed fishers from different local communities to characterize: i) knowledge shark fisheries, ii) those reliant upon these resources, iii) their perceptions about populations importance Island. A total 111 semi-structured interviews were...
Abstract One of the chief consequences climate change is worldwide redistribution species in pursuit physiologically and ecologically favourable conditions. As part one most threatened groups vertebrates, assessing how may affect distribution patterns key shark essential for their long-term conservation management. The present study aims to assess projections (based on representative concentration pathways 2.6, 4.5, 6.0, 8.5) middle end century global habitat suitability (HS) large...
