“…Although counterintuitive, the direct mortality inflicted by apex consumers on prey species may improve the long-term survival of these prey populations. Predators eliminate sick individuals from prey populations, thus increasing the overall health of the population (Severtsov and Shubkina 2015). Moreover, the prevalence of disease epidemics is strongly linked to population density (Lafferty 2004).…”

Marine biodiversity plays an important role in providing the ecosystem functions and services which humans derive from the oceans. Understanding how this provisioning will change in the Anthropocene requires knowledge of marine biodiversity patterns. Here, we review the status of marine species diversity in space and time. Knowledge of marine species diversity is incomplete, with only 11% of species described. Nonetheless, marine biodiversity is clearly under threat, and habitat destruction and overexploitation represent the greatest stressors to threatened marine species. Claims that global marine extinction rates are within historical backgrounds and lower than on land may be inaccurate, as fewer marine species have been assessed for extinction risk. Moreover, extinctions and declines in species richness at any spatial scale may inadequately reflect marine diversity trends. Marine local-scale species richness is seemingly not decreasing through time. There are, however, directional changes in species composition at local scales. These

“…Understanding the contribution of predators in shaping the structure of ecological communities is a central issue in ecology (Lima, 1998;Schmitz, 2007;Seibold et al, 2018). Predator-prey interactions are a main driver of natural selection, population dynamics, food web structure, community assembly, and ecosystem functioning (Portalier et al, 2019;Severtsov & Shubkina, 2015;Start et al, 2020). Spiders are among the most abundant predators in terrestrial ecosystems, playing an important role in controlling prey species populations (Betz & Tscharntke, 2017;Michalko et al, 2019;Pekár et al, 2011;Pusceddu et al, 2018).…”

“…For decades, Saiga antelope has to adapt to artificial feeding surroundings, and its lifestyle has taken great changes from its original wild states. Currently, the study on adaptability of Saiga mainly focuses on behavioural flexibility and population subdivision (Kokshunova, Gavrilenko, Treus, & Smagol', 2005; Ratajczak et al., 2016; Severtsov & Shubkina, 2015), little is known about lifestyle‐related functional adaptation of bone morphology.…”

The intralimb indices and calcaneal linear metrics are known as the reliable predictors of locomotor adaptation in artiodactyls. The osteological features of hindlimb in adult Saiga (Saiga tatarica) were described, and its correlation with cursoriality and habitat adaptation was discussed. Gross anatomy data showed Saiga owned the deep acetabulum as a broad lunate surface, the large acetabular anteversion, the well‐developed ischiatic tuberosity and the prominent gluteal lines. It also presented the robust rough line and the strong gluteal tuberosity. A proximodistally elongated eminence located on the cranially distal tibia, which had not been found in goat. The tibial extensor groove was deep. The calcaneal tuberosity was robust. Digital anatomy data showed Saiga owned the higher metatarsal‐femur ratio than forest musk deer and sheep. Comparing with wild bovids and sheep, Saiga presented a transitional variation in calcaneal form. The mean greatest length of the calcaneus (GLC) and the height of the sustentacular facet (HSF) in Saiga were shorter than that in sheep and longer than that in wild bovids respectively (F = 587.492; F = 10.264, p < .05). The wild bovids had longer cubonavicular facets than the other two groups (F = 18.587, p < .05). The great metatarsal–femur ratio of Saiga implied a superior cursorial ability and high conservation confronting the different habitats. The calcaneal linear metrics might shed light on lifestyle‐related functional adaptation over decades of short‐term evolution in the semi‐free range environment.
