A global ecological signal of extinction risk in terrestrial vertebrates
<p>To determine the distribution and causes of extinction threat across functional groups of terrestrial vertebrates, we assembled a dataset on ecological traits for 18,016 species and tested, using phylogenetic comparative methods, which categories of habitat association, mode of locomotion, and feeding mode best predict extinction risk. We found that cave-dwelling amphibians, brachiating mammals (all of which are primates), aerial and scavenging birds, and pedal squamates are all disproportionately threatened with extinction. Across four vertebrate classes, agriculture, followed by logging, and then invasive species and disease are the most common risk factors of extinction. The most endangered species show simultaneous risk from multiple threat types. The disproportionate loss of species with certain functional traits, combined with increasing anthropogenic pressures, is likely to disrupt ecosystem functions globally if left unabated. A shift in focus from species- to trait-centric conservation practices will allow for the protection of at-risk functional diversity from regional to global scales.</p>
Data from: The fifth review of Birds of Conservation Concern in the United Kingdom, Channel Islands and Isle of Man and second IUCN Red List assessment of extinction risk of birds for Great Britain
<p>The fifth review of <i>Birds of Conservation Concern</i> (<i>BoCC5</i>) in the UK, Channel Islands and Isle of Man assessed and assigned 245 species to updated Red, Amber and Green lists of conservation concern and showed a continuing decline in the status of our bird populations. In total, 70 species (29% of those assessed) are now on the Red list, up from 36 species in the first review in 1996. Since the last review, in 2015, Golden Oriole <i>Oriolus oriolus</i> has been lost as a breeding species. Eleven species have been moved to the Red list, while only six species moved from Red to Amber. Newly Red-listed species include Common Swift <i>Apus apus</i>, Common House Martin <i>Delichon urbicum</i>, Greenfinch <i>Chloris chloris</i> and the globally threatened Leach's Storm-petrel <i>Hydrobates leucorhous</i>. There has been no improvement in the overall status of species associated with farmland and upland, or Afro-Palearctic migrants; indeed, more such species have been Red-listed. Concerns over the status of our wintering wildfowl and wader populations have also increased. As a direct result of targeted conservation action, White-tailed Eagle <i>Haliaeetus albicilla</i> moves from Red to Amber.</p> <p>We also present a review of the separate, and distinct, second IUCN Regional Red List assessment of extinction risk for Great Britain, which show that 46% of 235 regularly occurring species, and 43% of 285 separate breeding and non-breeding populations, are assessed as being threatened with extinction from Great Britain.</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>
