The evolutionary fitness of any predator, whether it is a spider catching insects or a lion hunting buffalo, depends largely on the quality and quantity of its diet. Predatory strategies are shaped and refined by natural selection to maximize nutrient intake within the bounds of a wide range of ecological constraints (e.g., prey density, habitat) t...
The idea that offspring sex ratio is affected by parental capacity for
reproductive investment was first developed by Trivers and
Willard1 and later elaborated by others2-6.
According to this hypothesis, if the amount of parental
investment7 differentially affects the expected reproductive
success of offspring depending on offspring gender, then pa...
Tiger Moon is the powerful, poetic story of the Sunquists' two years studying tigers in Nepalâtraveling by elephant, avoiding a rhino attack, and learning to recognize individual tigers by roar. A new afterword tells the story of promising efforts to reconnect fractured Nepalese tiger habitats.

... Leopard cats weigh 1-5 kg in Southeast Asia (Castelló, 2020;Sunquist & Sunquist, 2014) and are generally considered nocturnal or crepuscular (Azlan & Sharma, 2006;Chen et al., 2016;Grassman, 2000;Mohamed et al., 2013;Smith et al., 2010). Their diet mainly consists of rodents, especially in the Muridae family, but also includes birds, insects, and other small animals (Bashir et al., 2014;Chuang, 2012;Kamler et al., 2020;Rajaratnam et al., 2007;Shehzad et al., 2012;Sunquist & Sunquist, 2017). ...

... Previous studies conducted across the Indian sub-continent have also found chital to be a significant part of leopard and lion diets (Biswas and Sankar 2002;Andheria et al. 2007;Ahmad and Khan 2008;Mondal et al. 2011;Meena et al. 2011;Harihar et al. 2011;Lovari et al. 2015;Upadhyaya et al. 2018;Ahmad and Khan 2022). Several factors influence predation by large carnivores on prey species, including prey abundance and weight, spatiotemporal overlap between predator and prey, and habitat use of both predator and prey (Holling 1959;Sunquist and Sunquist 1989;Allen et al. 2022). In Gir, chital exist at high density (55.66 individuals/km 2 ) , resulting in a high encounter rate with both leopards and lions, and therefore increased predation on chital. ...
... Both mitochondrial and nuclear markers revealed the absence of any trace of genetic structuring and possible barriers to dispersal in AMVA. Although the home range of this species is relatively small in relation to the extent of the AMVA (0.16 km² for females and 1.23 km² for males, [Sunquist and Austad 1987]), the area that an opossum occupies is quite dynamic and often changes as these animals do not remain in their dens for more than ve days, thus facilitating their dispersal and connectivity over large distances. The fact that no genetic structure was evidenced with either type of marker is consistent with the absence of sexual bias in the dispersal of this species in AMVA (Ballard and Whitlock 2004). ...

... The highest overlap value (∆1) occurs with mouse deer (0.65), followed by barking deer (0.61), macaques (0.58), and wild boars (0.46). Marbled cats were nocturnal (Sunquist, 2002), but other examinations reported diurnal activity for marbled cats (Kamler et al. 2020;Sunarto et al. 2015). These cats had to divide resources among competitors or select prey species to coexist with larger cats (Dröge et al. 2017). ...
... Something similar occurred in French Guiana with the pioneering works led by Charles-Dominique et al. (1981) and then Atramentowicz (1986). Indeed, the 1980s saw the start of dedicated studies focusing on ecology and biogeography in South America, with other relevant research projects scattered across the continent, such as those of August (1981), Austad and Sunquist (1986), Cordero andNicolas (1987), andO'Connell (1989) in Venezuela. At that time, opossums of the genus Didelphis were usually the focus of ecological (or other biological) studies (see Fig. 2 in ▶ Chap. ...
... In current times, managers are challenged by tigers that injure or kill humans and cattle or take up temporary residence in farmlands (Singh 1970, Greenough 2003, Shukla 2013. Ostensibly, conservation measures to increase vulnerable tiger populations may in some cases exacerbate human-tiger conflict (Sunquist and Sunquist, 1988), and this has led to a polarized debate on tiger conservation in India (Narain et al 2005, Karanth 2011), particularly with regard to the presence of human settlements within tiger habitats, and access of the public to forest resources. ...
