Bifurcations and multistability on the May-Holling-Tanner predation model considering alternative food for the predators
; ; Rojas, Alejandro
; (2019)
In this paper a modified May-Holling-Tanner predator-prey model is analyzed, considering an alternative food for predators, when the quantity of prey i scarce. Our obtained results not only extend but also complement ...

Bifurcations in a leslie-gower type predator-prey model with a rational non-monotonic functional response
(2022)A Leslie-Gower type predator-prey model including group defense for-mation is analyzed. This phenomenon, described by a non-monotonic function origi-nates interesting dynamics; positiveness, boundedness, permanence of ...

Blocking facial mimicry affects recognition of facial and body expressions
(2020)Facial mimicry is commonly defined as the tendency to imitate—at a sub-threshold level—facial expressions of other individuals. Numerous studies support a role of facial mimicry in recognizing others’ emotions. However, ...
