Figure 2 in Reviewing the status and demise of the Endangered Eld's deer and identifying priority sites and conservation actions in Cambodia
Figure 2: Distribution of Eld's deer records in Cambodia up to 2020, divided into three regions: northern, eastern and central-western Cambodia. Management area boundaries, including protected areas, districts and communes, have been used to illustrate where records have occurred, and as such does not depict the actual extent of Eld's deer in each location. Svay Leu and Kaoh Nheaek Districts and Srayang Commune overlap with protected areas, however Eld's deer were recorded outside of the protected areas so only the proportion of the district/ commune outside of protected areas is shown. The historical distribution of Eld's deer prior to 2000 was outside the scope of the review, however we included any locations with pre-2000 records that appeared within our literature review. Therefore, this map is not an accurate reflection of Eld's deer historical distribution. The white area on the map is not necessarily lacking Eld's deer, given suitable habitat, but is unsurveyed.
Threatened and endangered bird species and critical habitats in US cities
<p>Cities have classically been viewed as biologically impoverished, homogenized, and simplified systems that harbor low value for biodiversity. However, recent work has demonstrated that cities are critical ecological systems that provide important services to humanity and biodiversity. Cities can play vital roles in conserving biodiversity as well as habitats, providing system stability, and offering direct opportunities for people to engage with nature. In a rapidly changing world with biodiversity loss at an all-time high, cities have the potential to act as sanctuaries for biodiversity conservation. Here, we propose a "cities as sanctuaries" concept, which demonstrates the importance of cities for ecology and conservation, and provide the groundwork for advancing this novel field of study.</p>
FIG. 1 in Habitat Usage, Dietary Niche Overlap, and Potential Partitioning between the Endangered Spotted Turtle (Clemmys guttata) and Other Turtle Species
FIG. 1. The path analysis shows the relationship between habitat parameters associated with PC1 (which was strongly positively loaded with salinity, depth, dissolved O2, canopy cover, and pH) and three turtle species: Chrysemys picta, Kinosternon subrubrum, and Clemmys guttata on the Atlantic Coastal Plain. The solid and dashed lines represent direct and indirect effects, respectively, and black lines indicate positive effects while gray lines indicate negative effects. The numbers associated with each line represent the direction and magnitude of each effect, with the strength of the interaction increasing as the values approach 1.
FIG. 2 in Habitat Usage, Dietary Niche Overlap, and Potential Partitioning between the Endangered Spotted Turtle (Clemmys guttata) and Other Turtle Species
FIG. 2. Biplots of d15N and d13C for four turtle species at all sites with ellipses around each species (filled squares/solid black line ¼ Kinosternon subrubrum, filled triangles/solid gray line ¼ Chrysemys picta, open circles/gray dashed line¼ Chelydra serpentina, filled diamonds/ lack dashed line ¼ Clemmys guttata). There is a large overlap in isotopic compositions for all species, resulting in no significant differences in isotopic niche space between species (see text).
FIG. 3 in Habitat Usage, Dietary Niche Overlap, and Potential Partitioning between the Endangered Spotted Turtle (Clemmys guttata) and Other Turtle Species
FIG. 3. Bivariate SIBER (Stable Isotope Bayesian Ellipses in R) plots of ellipses estimating isotopic niche based on the d13C and d15N compositions with all species, excluding C. serpentina. The black circles represent the mode, while the three ellipses from the center outwards show where 50%, 75%, and 95% of the data lie, respectively. The numbers indicate the site numbers, while the letter codes indicate species names (MUDT ¼ Kinosternon subrubrum, PATU ¼ Chrysemys picta, SPTU ¼ Clemmys guttata). Together, these bivariate data of the isotopic compositions create ellipses which represent the relative sizes of the isotopic niche of each turtle species at all of our sites on the Atlantic Coastal Plain. Despite the lack of any significant differences in isotopic niche, these ellipses allow us to see some degree of niche overlap among C. guttata at all sites.
Identification of upper thermal thresholds during development in the endangered Nechako white sturgeon with management implications for a regulated river
<p>Climate change-induced warming effects are already evident in river ecosystems and projected increases in temperature will continue to amplify stress on fish communities. Additionally, many rivers globally are impacted by dams which have many negative effects on fishes by altering flow, blocking fish passage, and changing sediment composition. However, in some systems, dams present an opportunity to manage river temperature through regulated releases of cooler water. For example, there is a government mandate for Kenney dam operators in the Nechako River, BC Canada, to maintain river temperature below 20°C in July and August to protect migrating sockeye salmon (<em>Oncorhynchus</em> <em>nerka</em>). However, there is another endangered fish species inhabiting the same river, Nechako white sturgeon (<em>Acipenser</em> <em>transmontanus</em>), and it is unclear if these current temperature regulations, or timing of the regulations, are suitable for spawning and developing sturgeon. In this study, we aimed to identify upper thermal thresholds in white sturgeon embryos and larvae to investigate if exposure to current river temperatures are playing a role in recruitment failure. We incubated embryos and yolk-sac larvae in three environmentally relevant temperatures (14°, 18°C, and 21°C) throughout development to identify thermal thresholds across different levels of biological organization. Our results demonstrate upper thermal thresholds at 21°C across physiological measurements in embryo and yolk-sac larvae white sturgeon. Prior to hatch, both embryo survival and metabolic rate were reduced at 21°C. Following hatch, sublethal consequences continued at 21°C as larval sturgeon had decreased thermal plasticity and a dampened transcriptional response during development. In recent years, the Nechako River has reached 21°C by the end of June, and at this temperature, a decrease in sturgeon performance is evident in most of the traits measured. As such, the thermal thresholds identified here suggest current temperature regulations may not be suitable for developing white sturgeon and future recruitment.</p>
