Simulación del movimiento del aire en un invernadero tipo venlo

Terra Latinoamericana, 2013
Se han realizado aproximaciones teóricas para estudiar la ventilación en invernaderos como los modelos mecanicistas, que se basan en el balance de energía, pero sólo proveen información acerca de la tasa de ventilación global sin ofrecer detalles de la ...

From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

Functional Ecology, Volume 40, Issue 6, Page 1906-1920, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico

Conservation Biology, Volume 40, Issue 3, June 2026.
Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

Effects of landscape context on avian specialist response to increased surface temperature in protected areas

Conservation Biology, Volume 40, Issue 3, June 2026.
Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

Análisis espacial de los precios del suelo de uso agrario

Economía Agraria y Recursos Naturales, 2018
<p>Since 1983, the Spanish administration publish the national land prices survey, whose main objective is to measure the prices evolution of agricultural land. The Survey provides objective reference prices without speculative effects, by Autonomous Communities and differentiated by the most representative uses in each one of them. We start from

Disentangling conservation asymmetries through socio‐economic transboundary factors across the Alto Paraná Atlantic Forest of South America

People and Nature, Volume 8, Issue 5, Page 1328-1348, May 2026.
Abstract Ecoregions are often defined based on homogeneous biophysical and ecological conditions and are optimal spatial units for designing conservation strategies. However, transboundary ecoregions such as the Alto Paraná Atlantic Forest (APAF) experience asymmetrical conservation outcomes, understood here as cross‐border differences, resulting from ...
