To conserve threatened farmland species requires an estimate of the representation of their habitats within protected areas, especially in countries with inadequate mechanisms for protecting and managing habitats outside of protected areas. We conducted a gap analysis to evaluate the conservation status of suitable habitats for two threatened farmland bird species - corncrake (Crex crex) and lesser grey shrike (Lanius minor) - within the networks of national protected areas (NPAs) and important bird areas (IBAs) in Serbia. We determined the distribution of suitable habitats using MaxEnt based on climate, topography and land-cover variables. We found that the proportion of suitable habitats within the NPAs is very low (12.31% and 2.04% for the corncrake and lesser grey shrike, respectively), although it is significantly higher for both species within IBAs (25.86% and 9.91%, respectively). Upland farmland habitats (preferred by corncrake) are better represented within both networks (especially IBAs) than lowland habitats (preferred by lesser grey shrike). Our spatially explicit distribution models identify suitable habitats within and beyond the NPAs and IBAs that require monitoring and appropriate conservation measures. The low representation of suitable habitats within these networks is an obstacle to the conservation of both species and other farmland birds in Serbia.

This case study describes a partnership between the Avian Research and Education Institute (AREI), College of Mount St. Joseph (MSJ), University of Cincinnati (UC), and science teachers at The Seven Hills Middle School. This partnership enabled the teachers to implement a Bird Studies program and empowered the students to become citizen scientists. The partners used various technologies to establish and maintain an ongoing relationship between the field and classroom, so that students interacted with field ornithologists face-to-face and virtually via the Internet. In the classroom, students assisted researchers as they color-banded birds that visited the school’s wild bird garden. The students then monitored the banded birds, communicated with the researchers, posted updates on the class wiki, conducted biweekly bird counts and submitted data to eBird, created eField Guides, completed inquiry projects, and presented their data at a school event and a community bird festival.

The popularity of wild bird feeding has introduced enormous amounts of additional food into the ecosystem, especially in urban areas. Significantly, all of this food is supplementary to the natural diet of the birds consuming it. For this reason, bird feeding has been likened to a supplementary feeding experiment on a global scale yet with no clear expectations of possible outcomes. This chapter investigated the likely consequences of this situation.

AbstractUsing interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador during the early years of its existence (1970–6). This period was marked by the inability of the ERP to maintain internal coherence or any consensus on revolutionary strategy, which led to a series of splits and internal fights over control of the organisation. The evidence marshalled in this case study sheds new light on the origins of the armed Salvadorean Left and thus contributes to a wider understanding of the processes of formation and internal dynamics of armed left-wing groups that emerged from the 1960s onwards in Latin America.

Abstract Culture shapes our basic sensory experience of the world. This is particularly striking in the study of religion and psychosis, where we and others have shown that cultural context determines both the structure and content of hallucination-like events. The cultural shaping of hallucinations may provide a rich case-study for linking cultural learning with emerging prediction-based models of perception.
