THE AESTHETICS OF URBAN METABOLISM: Landscape, Design and the Politics of In/Visibility

open access: yesInternational Journal of Urban and Regional Research, Volume 50, Issue 3, Page 644-666, May 2026.
Abstract In this article, we chart the evolving aesthetic contours of urban metabolism across London, focusing on the River Lea and Thamesmead to the north and south of the River Thames, respectively. We begin in the nineteenth century, when these two sites formed critical nodes within a new sewerage system that relegated the city's circulatory flows ...

Bumblebee assemblages (Hymenoptera, Apidae) of ruderal habitats in the Kola Peninsula, NW Russia

open access: yesFauna Norvegica, 2015
Bumblebee assemblages of ruderal habitats were studied in the Kola Peninsula in 2012. The number of species in the assemblages varies from 7 to 11. Of cryptic species Bombus sensu stricto in the Kola Peninsula only Bombus cryptarum was registered.

A Target Restricted Assembly Method (TRAM) for Phylogenomics [PDF]

open access: yes, 2010
While next generation sequencing technology can produce sequences covering the entire genome, assembly and annotation are still prohibitive steps for many phylogenomics applications.

Heterospecific Hymenoptera found inside the nests of Bombus impatiens (Hymenoptera: Apidae). [PDF]

open access: yes, 2018
The nests of social Hymenoptera are particularly attractive to species engaging in resource robbing due to their concentration of resources. Here, the identity of heterospecific intruders in Bombus impatiens nests are described, with a particular focus ...

Bee community and trait‐based responses to fire in a Mediterranean landscape

open access: yesInsect Conservation and Diversity, Volume 19, Issue 3, Page 530-547, May 2026.
Fire drives a short‐term increase in bee abundance and diversity, despite its strong negative impact on floral resources. Acting as an environmental filter, fire shapes bee communities as increased post‐fire fine‐scale heterogeneity favors bees with specific functional traits such as ground‐nesting and generalist species.

Hybridization between wild and cultivated potato species in the Peruvian Andes and biosafety implications for deployment of GM potatoes [PDF]

open access: yes, 2008
The nature and extent of past and current hybridization between cultivated potato and wild relatives in nature is of interest to crop evolutionists, taxonomists, breeders and recently to molecular biologists because of the possibilities of inverse gene ...

Short communication: First data on the prevalence and distribution of pathogens in bumblebees (Bombus terrestris and Bombus pascuorum) from Spain

open access: yes, 2017
Bumblebees provide pollination services not only to wildflowers but also to economically important crops. In the context of the global decline of pollinators, there is an increasing interest in determining the pathogen diversity of bumblebee species.

Chemical communication is not sufficient to explain reproductive inhibition in the bumblebee Bombus impatiens

open access: yesRoyal Society Open Science, 2016
Reproductive division of labour is a hallmark of eusociality, but disentangling the underlying proximate mechanisms can be challenging. In bumblebees, workers isolated from the queen can activate their ovaries and lay haploid, male eggs.

Estimating wild bee population size with validated distance sampling

open access: yesInsect Conservation and Diversity, Volume 19, Issue 3, Page 469-483, May 2026.
Distance Sampling is a promising method to estimate population size but has never been validated on insects. We validated it on a honey bee population of known size. We applied Distance Sampling to three insular pollinators and found that estimates are consistent across days, match species phenology and reflect the expected influence of weather ...

The Modified Pharaoh Approach: Stingless bees mummify beetle parasites alive [PDF]

open access: yes, 2008
Social insect colonies usually live in nests, which are often invaded by parasitic species^1^. Workers from these colonies use different defence strategies to combat invaders^1^.
