Total length 1.57 (1.68 with clypeus), prosoma 0.56 long, 0.50 wide, opisthosoma 1.01 long, 0.73 wide; tibia I: 2.63; tibia I L/d: 47. Eye interdistances and diameters: PME-PME 0.13, PME 0.07, PME-ALE 0.01, AME absent. Sternum width/length: 0.59/0.41. Epigyne (Figs 8A, 10E) simple and flat, with four spine-shaped apophyses (lateral two forked) and pair of postero-lateral pockets 0.25 apart (ep in Figs 8B, 10F).

Cyclicity of the Limit Periodic Sets for a Singularly Perturbed Leslie-Gower Predator-Prey Model with Prey Harvesting
No full textIn this paper, we study the Leslie–Gower predator–prey model with Michaelis–Menten type
prey harvesting. Our main focus is on the cyclicity of diverse limit periodic sets, including a
generic contact point, canard slow–fast cycles, transitory canards, slow–fast cycles with two
canard mechanisms, singular slow–fast cycle, etc. We develop new techniques for finding the
maximum number of limit cycles produced by slow–fast cycles containing both the generic
and degenerate contact point away from the origin (such slow–fast cycles are the transitory
canards and cycles with two canard mechanisms). It can be applied not only to the Leslie–
Gower predator–prey model, but more general systems as well. The main tool is geometric
singular perturbation theory including cylindrical blow-up and the notion of slow divergence
integral. We also study dynamics near the origin using non-standard techniques (constructing
generalized normal sectors). The uniqueness and stability of a relaxation oscillation is shown
using the notion of entry–exit function. Some interesting dynamical phenomena, such as
relaxation oscillation and canard explosion, are simulated to illustrate the theoretical results.Acknowledgements
