... Females with kittens have higher nutritional demands due to raising offspring and extended periods without ungulate prey can affect reproductive success (Walton et al., 2017). Additionally, the significant differences in inter-kill intervals between adult males and single adult females could be connected to the differences in body size and the greater movements of males, probably linked to territorial defence, which increases their energetic needs (Sunquist & Sunquist, 2002). ...

Ecological and intrinsic drivers of foraging parameters of Eurasian lynx at a continental scale

... Although cats can distinguish between their owners and strangers, altering their behaviors accordingly 28 and showing different responses to the voices of their owners compared to those of strangers 29 , studies using the Strange Situation Test (SST) have found no significant differences in cat behaviors toward their owners and strangers 30 . Considering that the ancestral species of domestic cats, the African wildcat, is solitary and does not form groups 12 , it is plausible that even domestic cats living with humans may not perceive their owners as in-group members. This hypothesis is supported by evidence that even cats with higher levels of OT exhibit infrequent affiliative behaviors, such as allogrooming, indicating that they do not consider other cohabiting cats as part of their in-group 31 . ...

... Jaguars (Panthera onca) are apex predators in Neotropical forests that usually occur at low densities (Maffei et al. 2011, Noss et al. 2012 and have a relatively low reproduction rate, usually one or two cubs every three years (Seymour 1989). These characteristics, make them sensitive to threats such as habitat loss, reduction of wild prey, preventative and retaliatory killing as a result of conflict with livestock, and illegal killing for black-market trade (Weber & Rabinowitz 1996, Gittleman et al. 2001, Sunquist & Sunquist 2001, Reuter et al. 2018. The continuous increase in these threats has led to the decline and isolation of jaguar populations, considering them near threatened throughout their entire range (Quigley et al 2017). ...

Assessment of jaguars Panthera onca (Mammalia: Carnivora: Felidae) and their prey in Manu National Park

... inter-kill interval, searching and handling times) can vary according to multiple factors, such as availability, seasonality and distribution of prey (Elbroch et al., 2016), density of predators, presence of competitors and kleptoparasites (Smith et al., 2015;Zimmermann et al., 2015) and individual variability (Pettorelli et al., 2015). Understanding the impact of these factors can reveal how predators handle different environmental conditions to obtain the necessary energy input (Merrill et al., 2010;Sunquist & Sunquist, 1989). Since many solitary large predators tend to predate on large prey (similar size or larger than themselves, although prey size selection can vary greatly; see Bates-Mundell et al., 2024) and thus feed on a carcass for several days, kleptoparasitism by scavengers can also importantly affect the predator's feeding behaviour and kill rates (i.e. ...

... Within each study site, we established 12 camera locations, separated by at least 400 m. Based upon the published home range size of our target taxa [67][68][69] , this inter-camera distance makes it reasonable to treat each location as an independent sample of the resident carnivore community. ...

... They were primarily crepuscular and nocturnal, consistent with earlier findings (Chaudhary et al., 2020;Rafiq et al., 2020) and observed in other felids such as the leopard cat (Austin et al., 2007), cheetah (Rafiq et al., 2020), tiger (Wang et al., 2016;Yang et al., 2018), and lion (Chaudhary et al., 2020). Their heightened activity during twilight and at night is likely due to activity of their prey species (Jenny and Zuberbühler, 2005;Sunquist and Sunquist, 2002). Barking deer and wild boar, its primary prey species in this region (Kunwar and Koju, 2019), are most active during twilight and at night (Fig. 4). ...

... Combined effects of (iii) heterogeneous g0 and constant σ along with heterogeneous σ and constant g0 [g0(h2) σ (.) and g0(.)σ (h2)] were also modelled Kumar et al., 2019). Sunquist and Sunquist (2002) demonstrated that home range size and movement of large cats vary between the sexes, which has the potential to induce variability in the capture probability of individuals (Efford and Mowat, 2014). This latent variability was accounted for by modelling (iii) g0 and σ as a function of gender (g0(sex), σ (sex). ...
