Livestock production in drylands has greatly altered ecosystem level processes, including the interactions between sympatric species. Management of livestock predation on farms requires an acute understanding predator species' ecology, their intraguild interactions. In this study, we used camera trapping to investigate black-backed jackal (Lupulella mesomelas) and caracal (Caracal) spatiotemporal overlap different land-uses (viz., public private protected areas, a neighbouring group small-livestock farms) Karoo, South Africa. We also questionnaires understand how local farmers perceive factors influencing changes abundance trophic relationship them. Black-backed was high, largely independent land-use, positively influenced by presence other had higher overall occurrence than caracal, were more likely occur farmland either area. Farmers acknowledged that mesopredators may benefit from absence apex predators farmlands populations increased recent times. However, less certain as interact, whether they suppress one another influence perceived increase both abundance.

Fire occurrence affects the distribution of key resources for fauna in natural ecosystems worldwide. For fire management strategies adequate biodiversity conservation, understanding how species respond to fire-induced changes is essential. In this study, we investigated role regimes on spaces used by medium and large mammals at multiple spatial scales (0.8 ha 78.5 ha) a fire-prone savanna ecosystem (Brazilian Cerrado). We sampled using 60 camera traps distributed 30 sampling units located grassland typical formations. applied single-species occupancy models AIC-based model selection assess use space response pyrodiversity (both diversity frequencies ages), proportion recently burned area, long-unburned area while accounting detectability. Our results showed that regime variables affected study differently. Deer regardless mosaic specific ages. Fire-related variables, however, tapirs maned wolves. Tapirs preferred mosaics with lower frequencies, whereas wolves more intensively high age areas. Based our findings, recommend targeting mammal should not necessarily focus maximum pyrodiversity. Instead, suggest strategy combining “patch burning” maintenance fire-age patches suitable different species’ requirements.

Predator populations persisting in desert landscapes may be especially vulnerable to habitat fragmentation and changing climates, but many are chronically understudied at risk of extirpation. The Asiatic subspecies caracal, Caracal caracal schmitzi, inhabit the mountainous western southern Arabian Peninsula, they thought decline across region. In Saudi Arabia, a recent extensive study used camera traps face-to-face questionnaires survey leopards other medium- large-size mammals, simultaneously generating vast bycatch data on presence. We assessed interspecific temporal overlap identified factors that influence occupancy, predict their potential distribution historical range Arabia. From fourteen trap surveys, 497 independent captures caracals were recorded only nine south-western sites. Occupancy modelling showed occurred areas with higher gross primary productivity elevations, as well relative abundance free-roaming cats dogs, striped hyaena, wild prey. Higher abundances large predators decreased detection caracals. Caracals displayed cathemeral activity pattern peaks around sunrise sunset, had high diel wolves. Predictive south mountains stronghold for caracals, low occupancy or extirpation north elsewhere, was highly congruous predictions from false-positive 843 questionnaires. persistence is likely driven by increased vegetation prey associated regions, more frequent human presence potentially increases availability alternative prey, including cats. dry regions particularly climatic changes affecting abundance, have ability adapt benefit limited if conflict can avoided.
