Distribution. Near Halabiya at the Euphrates and Qal'at Sukkara (Syria); potentially in SW Iran. There are no recent records from Israel, Palestine or Lebanon indicating that the species is potentially extinct in this region. However, it cannot certainly be excluded that katinka is more common in the Levant and the Arabian Peninsula. in Soricidae

The extinct shark Otodus megalodon was a transoceanic super-predator: Inferences from 3D modelling
<p>Although shark teeth are abundant in the fossil record, their bodies are rarely preserved. Thus, our understanding of the anatomy of the extinct <em>Otodus megalodon </em>remains rudimentary. We used an exceptionally preserved fossil to create the first 3D model of the body of this giant shark and used it to infer its movement and feeding ecology. We estimate that an adult <em>O. megalodon</em> could cruise at faster absolute speeds than any shark species today, and fully consume prey the size of modern apex predators (e.g., the killer whale). A dietary preference for large prey potentially enabled <em>O. megalodon</em> to minimize competition and provided a constant source of energy to fuel prolonged migrations without further feeding. When taken together, our results suggest that <em>O. megalodon</em> played a singular ecological role as a transoceanic super-predator. As such, its extinction likely had large impacts on global nutrient transfer and trophic food webs.</p>

Geographic range size, water temperature and extrinsic threats predict the extinction risk in global cetaceans
<p><span>Despite that cetaceans provide significant ecological contributions to the health and stability of aquatic ecosystems, they are highly endangered with nearly one-third of species assessed as threatened with extinction. Nevertheless, to date, few studies have explicitly examined the patterns and processes of extinction risk and threats for this taxon, and even less between the two subclades (Mysticeti and Odontoceti). To fill this gap, we compiled a dataset of six intrinsic traits (active region, geographic range size, body weight, diving depth, school size and reproductive cycle), six environmental factors relating to sea surface temperature and chlorophyll concentration, and two human-related threat indices that are commonly recognized for cetaceans. We then employed phylogenetic generalized least square (PGLS) models and model selection to identify the key predictors of extinction risk in all cetaceans, as well as in the two subclades. We found that geographic range size, sea surface temperature and human threat index were the most important predictors of extinction risk in all cetaceans and in odontocetes. Interestingly, maximum body weight was positively associated with the extinction risk in mysticetes, but negatively related to that for odontocetes. By linking seven major threat types to extinction risk, we further revealed that fisheries bycatch was the most common threat, yet the impacts of certain threats could be overestimated when considering all species rather than just threatened ones. Overall, we suggest that conservation efforts should focus on small-ranged cetaceans and species living in warmer waters or under strong anthropogenic pressures. Moreover, further studies should consider the extinction risk of species when superimposing risk maps and quantifying risk severity. Finally, we emphasize that mysticetes and odontocetes should be conserved with different strategies, because their extinction risk patterns and major threat types are </span><span>considerably</span><span> different. For instance, large-bodied mysticetes and small-ranged odontocetes require special conservation priority.</span></p>

Humid tropical vertebrates are at lower risk of extinction and population decline in forests with higher structural integrity
<p>The four Excel workbooks contain processed data in the form of humid tropical forest area under each of multiple values of the Structural Condition Index (SCI), Forest Structural Integrity Index (FSII), and Human Footprint (HFP) for Mammal, Bird, Reptile and Amphibian species. The associated README text file contains metadata to describe the data in the xlsx workbooks. Python code to replicate geospatial analyses and R code to replicate statistical analyses are provided in the respective scripts. ArcGIS Pro is required to be installed prior to running the Python script.</p>
