“…In the juvenile stage, four impacts was negative (movement, reproduction, nutrition and survival), growth rate was positive and sensitivity was considered as positive [i.e. new environmental conditions create refuge habitat for juveniles (Ryan et al, 2015)] and negative [i.e. reduction of oxygen levels limits the presence of turtle species (Clark et al, 2009)].…”

“…The impact of changing oxygen levels was recorded in Australia for Elusor macrurus hatchlings, a species with bimodal respiration which, nevertheless, cannot withstand hypoxia conditions for long periods of time (Clark et al, 2009). However, the eutrophication in water supply dams caused by agricultural runoff, may benefit some turtle species, for example an increase in emergent vegetation could be potential refuge habitat for the juvenile stages of Chelodina longicollis [Table 3, (Ryan et al, 2015)]. Additionally, adults of Actinemys marmorata and Pseudemys scripta are benefited by the higher water temperatures in reservoirs that increased the time available for foraging and growth rates [Table 3, (Gibbons, 1970; Snover et al, 2015)].…”

Dams create many impacts on freshwater ecosystems and biodiversity. Freshwater turtles are at direct and indirect risk due to changes caused by damming including the loss of terrestrial and aquatic nesting and feeding habitats, changes to resource availability and reduced dispersal. We reviewed the global scientific literature that evaluated the impact of dams on freshwater turtles, and carried out additional searches of literature published in seventeen languages for studies evaluating actions to mitigate the impact of dams. The search produced 43 published articles documenting dam impacts on 29 freshwater turtle species from seven families (Chelidae, Chelydridae, Emydidae, Geoemydidae, Kinosternidae, Podocnemididae and Trionychidae) in 13 countries. More than a third of studies (41.9%, n = 18) focused on nine North American species of the Emydidae. Few studies were found from Europe and Asia and none from Africa. The number of studies, life-history stage studied and threat status differed significantly between temperate and tropical latitudes. Most studies were from temperate latitudes, where studies focused more on adults and less threatened species compared with tropical latitudes. Studies evaluated dam impacts as barriers and changes to water flow and quality, but no studies were found that assessed turtles and changes to land cover or mercury caused by dams. More than half of the studies (59%, n = 24) suggested actions to help mitigate dam impacts. Yet, only four studies on three temperate and one tropical species documented the effect of interventions (dam removal, flow management, artificial pond maintenance and community-based action). These findings demonstrate a lack of documented evidence evaluating dam impacts on freshwater turtles particularly in tropical regions. This lack of evidence reinforces the importance of strengthening and maintaining robust long-term studies of freshwater turtles needed to develop effective conservation actions for this group of vertebrates.

26where wetland losses were concentrated. We estimated that ~40,000 individual turtles were 52 displaced or killed due to wetland loss and urbanisation. 53 6. Urbanisation was the leading cause of wetland loss and degradation in Western Sydney 54 between 2010 and 2017. Wetlands provide critical green infrastructure and significant green 55 space for social cohesion in urban areas. Integration of current wetlands, or the creation of 56 functional wetlands, is key for sustainable development of urban landscapes. Urban wetlands 57 (natural and constructed) may provide "biodiversity arks" for endangered species and 58 facilitate community led conservation programs. 59 urbanisation 61 changes in wetland abundance and surface area from 2010 -2017. We quantified changes in primary 130 land use (natural, urban or agricultural) over the same time period to determine if wetland loss is 131 associated with increased urbanisation. Lastly, we then created species distribution models for the 132
