Informal supply chains of wild meat from rural Amazonia and food security in an urban center. [PDF]
Conserv BiolAbstract Iquitos, the most populated city in the Peruvian Amazon, is a hub in the regional supply chain of wild meat and supplies urban consumers. Studies on wild meat consumption have focused primarily on markets, limiting the scope of species considered to those that are economically valuable and potential inferences from those data.

Normally Preordered Spaces and Continuous Multi-Utilities
Applied General Topology, 2016 We study regular, normal and perfectly normal preorders by referring to suitable assumptions concerning the preorder and the topology of the space. We also present conditions for the existence of a countable continuous multi-utility representation, hence

Fixed point theorems for Geraghty-type mappings applied to solving nonlinear Volterra-Fredholm integral equations in modular G-metric spaces [PDF]
Arab Journal of Mathematical Sciences, 2021 Purpose – The authors prove the existence and uniqueness of fixed point of mappings satisfying Geraghty-type contractions in the setting of preordered modular G-metric spaces.

On nominal sets with support-preorder [PDF]
Categories and General Algebraic Structures with Applications, 2022 Each nominal set 𝑋 can be equipped with a preorder relation ⪯ defined by the notion of support, so-called support-preorder. This preorder also leads us to the support topology on each nominal set.

Updating Utility Functions on Preordered Sets
Mathematics, 2023 We consider the problem of extending a function fP defined on a subset P of an arbitrary set X to X strictly monotonically with respect to a preorder ≽ defined on X , without imposing continuity constraints.

Permutation Groups Generated by γ-Cycles
Axioms, 2022 A γ-cycle is a cycle of the form (i+1,i+2,…,i+m) in the symmetric group Sn. We study the subgroups of Sn generated by several sets of γ-cycles. Our mathematical development is strongly supported by computational experiments and proofs based on do-it ...

Remarks on contractive type mappings
Fixed Point Theory and Applications, 2017 We present an analog of Banach’s fixed point theorem for C J M $CJM$ contractions in preordered metric spaces. These results substantially extend theorems of Ran and Reurings’ (Proc. Am. Math. Soc.

Representations of ordered semigroups and the Physical concept of Entropy
Applied General Topology, 2004 The abstract concept of entropy is interpreted through the concept of numerical representation of a totally preordered set so that the concept of composition of systems or additivity of entropy can be analyzed through the study of additive ...

Order compatibility for Cauchy spaces and convergence spaces
International Journal of Mathematics and Mathematical Sciences, 1987 A Cauchy structure and a preorder on the same set are said to be compatible if both arise from the same quasi-uniform convergence structure on X. Howover, there are two natural ways to derive the former structures from the latter, leading to strong and
