Amplification success of multilocus genotypes from feathers found in the field compared with feathers obtained from shot birds

Johansson, Magnus P. ; McMahon, Barry J. ; Höglund, Jacob ; Segelbacher, Gernot (Wiley-Blackwell, 2012-01)

Effective DNA extraction methods from bird feathers have facilitated non-invasive sampling, leading to the suggestion that feathers are a great source for genetic studies. However, few studies have assessed whether all ...
An assessment of bird species within Irish agricultural landscapes using the Field Boundary Evaluation and Grading System.

McMahon, Barry J. ; Sheridan, Helen ; Kinsella, Anne ; Purvis, Gordon (Taylor & Francis, 2010-02-04)

Capsule The Field Boundary Evaluation and Grading System (FBEGS) is a useful predictor of bird populations found in field boundaries located in southeast Ireland. Aims To assess the potential of FBEGS to evaluate the ...
Breeding bird populations of Irish peatlands : capsule peatlands are very important habitats for birds despite low species diversity

Bracken, Fintan ; McMahon, Barry J. ; Whelan, John (British Trust for Ornithology / Taylor & Francis, 2008)

Aims to describe the variation in breeding bird populations that occur on different types of Irish peatlands and their associated habitat characteristics. Methods: Bird abundance and diversity were compared between four ...
A comparison of winter bird communities in agricultural grassland and cereal habitats in Ireland: implications for Common Agricultural Policy reform

McMahon, Barry J. ; Carnus, Tim ; Whelan, John (Taylor & Francis, 2013-01-16)

Capsule. In winter, grassland sites had greater bird numbers compared to winter cereals, but a number of species of conservation concern were exclusively recorded on winter cereals. Aims. To compare the winter bird ...
Different bioindicators measured at different spatial scales vary in their response to agricultural intensity

McMahon, Barry J. ; Anderson, Annette ; Carnus, Tim ; Helden, Alvin ; Kelly-Quinn, Mary ; Maki, Amel ; Sheridan, Helen ; Purvis, Gordon (Elsevier, 2012-07)

Ecologically, potential bioindicator taxa operate at different scales within agricultural ecosystems, and thereby provide a means to investigate the influence of changing management practice on biological diversity at ...
Genetic variation among endangered Irish red grouse (Lagopus lagopus hibernicus) populations: implications for conservation and management.

McMahon, Barry J. ; Johansson, Magnus P. ; Piertney, Stuart B. ; Buckley, Kieran ; Höglund, Jacob (Springer, 2012-06)

Extant populations of Irish red grouse (Lagopus lagopus hibernicus) are both small and fragmented, and as such may have an increased risk of extinction through the effects of inbreeding depression and compromised adaptive ...
Identifying set-aside features for bird conservation and management in northeast Iberian pseudo-steppes

McMahon, Barry J. ; Giralt, David ; Raurell, Montse ; Brotons, Lluís ; Bota, Gerard (Taylor & Francis, 2010-07-30)

Capsule. Set-aside (land temporally removed from agricultural production) features and their regional locations influence steppe-bird species of conservation concern in Catalonia. Aims. To identify set-aside features ...
Interactions between livestock systems and biodiversity in South-East Ireland

McMahon, Barry J. ; Helden, Alvin ; Anderson, Annette ; Sheridan, Helen ; Kinsella, Anne ; Purvis, Gordon (Elsevier, 2010-10-15)

Botanical and arthropod surveys at field level, and bird counts within field boundaries were undertaken on the same random sample of 50 grass-based farms in SE Ireland. Additional data relating to farm system, farm-level ...
