Plastic pollution and climate change have commonly been treated as two separate issues sometimes are even seen competing. Here we present an alternative view that these fundamentally linked. Primarily, explore how plastic contributes to greenhouse gas (GHG) emissions from the beginning end of its life cycle. Secondly, show more extreme weather floods associated with change, will exacerbate spread in natural environment. Finally, both occur throughout marine environment, ecosystems species can be particularly vulnerable both, such coral reefs face disease through climate-driven increased global bleaching events. A Web Science search showed studies ocean often siloed, only 0.4% articles examining stressors simultaneously. We also identified a lack regional industry-specific cycle analysis data for comparisons relative GHG contributions by materials products. Overall, suggest rather than debate over importance or pollution, productive course would determine linking factors between identify solutions combat crises.

Nesting range expansion of loggerhead turtles in the Mediterranean: Phenology, spatial distribution, and conservation implications

Global warming is affecting habitat quality and availability on our planet some species are predicted or by now changing their distribution range. Here we show that loggerhead turtles have already started to expand nesting range into the Western Mediterranean, which has until recently hosted only sporadic nests. We compiled information activity from beaches surrounding Mediterranean collected metadata turtle nests in Spain, France, Italy, Tunisia between 2010 2020 provide an exhaustive overview phenomenon of emerging new nest sites for turtles. The number recorded increased drastically since 2013 1 3 nests/year a record 84 registered 2020.

Key issues in assessing threats to sea turtles: knowledge gaps and future directions

Endangered Species Research, Год журнала: 2023, Номер 52, С. 303 - 341

Опубликована: Сен. 20, 2023

Sea turtles are an iconic group of marine megafauna that have been exposed to multiple anthropogenic threats across their different life stages, especially in the past decades. This has resulted population declines, and consequently many sea turtle populations now classified as threatened or endangered globally. Although some worldwide showing early signs recovery, still face fundamental threats. is problematic since important ecological roles. To encourage informed conservation planning direct future research, we surveyed experts identify key contemporary (climate change, take, fisheries, pollution, disease, predation, coastal development) faced by turtles. Using survey results current literature, also outline knowledge gaps our understanding impact these how targeted often involving emerging technologies, could close those gaps.

Adaptation of sea turtles to climate warming: Will phenological responses be sufficient to counteract changes in reproductive output?

Global Change Biology, Год журнала: 2023, Номер 30(1)

Abstract Sea turtles are vulnerable to climate change since their reproductive output is influenced by incubating temperatures, with warmer temperatures causing lower hatching success and increased feminization of embryos. Their ability cope projected increases in ambient will depend on capacity adapt shifts climatic regimes. Here, we assessed the extent which phenological could mitigate impacts from (from 1.5 3°C air 1.4 2.3°C sea surface 2100 at our sites) four species turtles, under a “middle road” scenario (SSP2‐4.5). Sand turtle nesting sites increase 0.58 4.17°C expected 26–43 days earlier not be sufficient maintain current incubation 7 (29%) sites, rates 10 (42%) trends hatchling sex ratio being able maintained half sites. We also calculated that would required (both backward for an shift forward later shift) keep up present‐day rates, ratios. The ranged −20 −191 days, whereas +54 +180 days.

Can a present-day thermal niche be preserved in a warming climate by a shift in phenology? A case study with sea turtles

Royal Society Open Science, Год журнала: 2023, Номер 10(2)

Опубликована: Фев. 1, 2023

How species respond to climate change may impact their extinction probability. Here we link climatology and ecology tackle a globally important conservation question. For sea turtles, there are concerns that warming will cause both the feminization of populations as well reduced hatchling survival. 58 nesting sites across world spanning all seven turtle species, investigated whether might be avoided by shifts in phenology cooler part year. We show even with most extreme phenological shift has been reported date-an 18-day advance per °C increase surface temperature (SST)-temperatures continue at warming. estimate SST rise an average 0.6°C (standard deviation = 0.9°C, n 58) when model 1.5°C combined best-case-scenario nesting. Since turtles exhibit temperature-dependent sex determination, these rises could lead increasingly female-biased ratios production world. These findings underscore for long-term survival this iconic group.

The effects of microplastic on the thermal profile of sand: implications for marine turtle nesting grounds

Frontiers in Marine Science, Год журнала: 2023, Номер 10

Опубликована: Май 29, 2023

Introduction Microplastics (i.e., plastic debris smaller than 5mm) found in coastal areas can impact the marine habitat used by endangered species since they may alter sand properties including temperature and permeability. Such alterations pose a significant threat to turtle populations as nest productivity, sexual development, hatchling fitness are dependent on conditions within nest, which incubate sand. Given that there is record of microplastic presence at nesting sites, this study was conducted explore potential influence microplastics thermal profile sediment typical habitat. Methods The experiment Florida State University Coastal Marine Laboratory where temperatures containers mixed with 5-30% v/v either black or white were recorded from July September 2018. Results addition resulted an increase – 0.017°C for each 1% microplastic. However, color did not have effect temperature. Overall, container 30% particles had highest mean 0.58°C (± 0.34°C) over control. Discussion results obtained indicate extreme concentrations could be issue turtles any changes affect sex ratio hatchlings and/or productivity.

Uncertain future for global sea turtle populations in face of sea level rise

Abstract Sea level rise has accelerated during recent decades, exceeding rates recorded the previous two millennia, and as a result many coastal habitats species around globe are being impacted. This situation is expected to worsen due anthropogenically induced climate change. However, magnitude relevance of increase in sea (SLR) uncertain for marine terrestrial that reliant on habitat foraging, resting or breeding. To address this, we showcase use low-cost approach assess impacts SLR turtles under various Intergovernmental Panel Climate Change (IPCC) scenarios different turtle nesting rookeries worldwide. The study considers seven with five species, categorized from vulnerable critically endangered including leatherback ( Dermochelys coriacea ), loggerhead Caretta caretta hawksbill Eretmochelys imbricata olive ridley Lepidochelys olivacea ) green Chelonia mydas ). Our combines freely available digital elevation models continental remote island beaches across ocean basins projections field data SLR. case focuses living species. Under moderate change scenarios, by 2050 it predicted at some 100% will be flooded, an extreme scenario could vanish. Overall, low slope those open such loggerheads might most future scenarios.
