A zoogeographical analysis of the vertical structure of the North Tian-Shanian butterfly fauna (Lepidoptera: Rhopalocera) and the questions of the faunagenesis in Central Asia [PDF]
A zoogeographical analysis performed for vertical structures of the butterfly fauna of North TianShan. The arealogical structure of this fauna includes 46 types of areals, grouped in 3 complexes (226 species).

Spatial niche segregation between bird species in the Białowieża primeval forest (NE Poland)
Drivers of bird niche separation in temperate primeval forests have not yet been determined, due to the low number of intact forest sites. Here, we analyzed the general patterns of niche usage on trees by birds’ assemblages.

Vertical Specialization and the Border Effect Puzzle [PDF]
A large body of empirical research finds that a pair of regions within a country tends to trade 10 to 20 times as much as an otherwise identical pair of regions across countries. In the context of the standard trade models, the large "border effect" is problematic, because it is consistent only with high elasticities of substitution between goods and ...

Vertical specialization across the world: A relative measure [PDF]
This article investigates the dynamics and the international distribution of vertical specialization (VS) - the use of imported inputs to produce goods that are afterwards exported. We propose a relative measure of VS-based trade that combines information from Input-Output matrices and international trade data, producing results for a large sample of ...

The nature and growth of vertical specialization in world trade [PDF]
Abstract Dramatic changes are occurring in the nature of international trade. Production processes increasingly involve a sequential, vertical trading chain stretching across many countries, with each country specializing in particular stages of a good’s production sequence.

Origami building blocks: Generic and special four-vertices [PDF]
Four rigid panels connected by hinges that meet at a point form a four-vertex, the fundamental building block of origami metamaterials. Most materials designed so far are based on the same four-vertex geometry, and little is known regarding how different geometries affect folding behavior.

Vertical specialization and the middle-income trap: an explanation based on global value chains
This paper aims to provide theoretical and empirical evidence to explain the middle-income trap from the perspective of Global value chains (GVCs). GVCs improve vertical specialization in two possible ways: (i) “economies of specialization”, induced by ...
