Central Place and Central Flow

, 2020
This chapter presents the idea of integrating central place and central flow theory in order to gain a deeper understanding of economic interactions, ranging from the local to the supra-regional scale. Central place theory is suitable to describe the local exchange relation-ships between settlements and their hinterland.

Rarity patterns and conservation priorities in Cactaceae species from the Southern Central Andes: a case study from the Calchaquíes Valleys, Salta, Argentina [PDF]

, 2016
En este trabajo se estudiaron 34 especies de Cactaceae de los Valles Calchaquíes, Argentina, para determinar 1) el nivel de rareza de las especies, 2) la proporción de especies raras entre grupos taxonómicos y ecológicos, y 3) la consistencia espacial de

When maize is not the first choice: advances in paleodietary studies in the Archaeological Site Río Doncellas (Jujuy, Argentina) [PDF]

, 2016
In this work we present new values of stable isotopes of carbon (δ13Cco and δ13Cap) and nitrogen (δ15N) measured in a sample of 13 human individuals found in the Río Doncellas Archaeological Site (Late Period or Regional Developments, ca. 1000 AD-1450 AD)

The scaling of seed‐dispersal specialization in interaction networks across levels of organization

Ecography, EarlyView.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

Environmental heterogeneity and spatial variation mediates plant diversity and ecosystem stability in mountain ecosystems of the Mediterranean Andes

Ecography, EarlyView.
Globally, mountains are highly diverse ecosystems that serve as natural laboratories for testing ecological theories, while providing vital ecosystem services. Their biodiversity arises from the interaction between elevational gradients and topographic complexity, which generate strong variation in environmental conditions across short spatial scales ...

Mamíferos silvestres en plantaciones forestales: ¿Una oportunidad para su conservación?

Caldasia, 2021
Las plantaciones forestales son monocultivos que han venido en aumento a nivel mundial. Estos siste-mas son menos diversos en comparación con bosques originales, pero pueden aportar a la conservación de la biodiversidad ya que son usadas por muchas ...

Loxodontomys pikumche (Rodentia, Cricetidae): nueva especie para Argentina [PDF]

, 2009
We report the first record of occurrence of Loxodontomys pikumche Spotorno et al., 1998, in the Central Andes of Argentina. We briefly describe external characters, skull, karyotype, and habitat; also, we provide general comparisons with the other known ...

Tracing the origins and evolution of nymphalid butterflies (Lepidoptera) in the Atlantic Forest

Ecography, EarlyView.
Understanding the relative roles of diversification and dispersal is key to explaining large‐scale biogeographical patterns. Although both processes are known to shape biodiversity, their relative contributions remain understudied for many organisms. Here, we examine how these processes have jointly contributed to the exceptional diversity and endemism

Anthropologist, heal thyself: Toward an anthropology of healing through relational interbeing

Feminist Anthropology, EarlyView.
Abstract I call for an anthropology that confronts its own woundedness. Anthropologists often bear witness to suffering but rarely examine how our own grief, trauma, and institutional distress shape the affective tone of our work. Drawing on fieldwork with Runa (Quechua) women affected by forced sterilization in Peru and guided by my collaborator and ...
