Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain

Wildlife Biology, EarlyView.
Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

Genetic differentiation in Scottish populations of the pine beauty moth Panolis flammea (Lepidoptera: Noctuidae) [PDF]

, 2005
Pine beauty moth, Panolis flammea (Denis & Schiffermüller), is a recent but persistent pest of lodgepole pine plantations in Scotland, but exists naturally at low levels within remnants and plantations of Scots pine.

Delineating seasonal shifts in reindeer habitat and diet selection by integrating GPS telemetry and stable isotope analysis

Wildlife Biology, EarlyView.
Seasonal changes shape herbivore behaviour by altering forage availability and habitat conditions; however, few studies integrate diet and habitat selection data across temporal scales. This study uses seasonality as a unifying framework to combine fine‐scale GPS‐based habitat selection data with broader‐scale dietary information from stable isotope ...

Variabibility of Glutamate-Oxalate-Transaminase (GOT-2.6.1.1) isoenzymes in open- pollinated progenyof homozygous Scots pine (Pinus sylvestris L.) trees

Acta Societatis Botanicorum Poloniae, 2014
The progeny of the two homozygotic Scots pine (Pinus sylvestris L.) plustrees was investigated as regards the GOT enzyme system to check the influence of 18 trees growing in the nearest neighbourhood.

Natural recovery of genetic diversity by gene flow in reforested areas of the endemic Canary Island pine, Pinus canariensis

, 2007
The endemic pine, Pinus canariensis, forms one of the main forest ecosystems in the Canary Islands. In this archipelago, pine forest is a mosaic of natural stands (remnants of past forest overexploitation) and artificial stands planted from the 1940's ...

Nests in trees are as good as or better than cliffs for two formerly persecuted, primarily cliff nesting eagles in Spain: a cautionary tale in defining the habitat of range‐restricted or threatened species

Wildlife Biology, EarlyView.
In the late‐20th century, golden and Bonelli's eagles suffered population declines on the Iberian Peninsula, partly due to human persecution. Habitat assessments – especially for Bonelli's eagles – always found or assumed strong associations with cliffs that provided nesting sites.

An adaptation study on four provenances of Scotch pine (Pinus sylvestris Linn) (Case study: Ladjim forest, Mazindaran) [PDF]

مجله جنگل ایران, 2012
This reserach was conducted to investigate the Scotch pine (Pinus sylvestris L.) adaptation in midland areas of Ladjim forests (Sari-Iran). The study was carried out as randomized completely block design with four treatments (based on different ...

Study of susceptibility of siberian pine (Pinus sibirica), scots pine (Pinus sylvestris) and siberian larch (Larix sibirica) seedlings to the pine wilt disease

Российский паразитологический журнал
The purpose of the research is to investigate the resistance of Pinus sylvestris, P. sibirica and Larix sibirica pine seedlings to the nematode Bursaphelenchus xylophilus to assess the potential risk of death of these conifers from pine wilt disease ...

Geography determines genetic relationships between species of mountain pine (Pinus mugo complex) in western Europe [PDF]

, 2010
Aim  Our aims were to test whether morphological species of mountain pines were genetically supported in the western part of the distribution range of the Pinus mugo species complex (Pinus mugo Turra sensu lato), to resolve genetically homogeneous ...

Both forest cover and land management practices explain variation in recovering pine marten densities

Wildlife Biology, EarlyView.
Robust monitoring of wildlife populations to guide interventions is fundamental to conservation and wildlife management. Understanding how landscape characteristics are influencing predator population dynamics is often vital to inform recovery strategies, management, and policy. The pine marten Martes martes is recovering in the UK; however, population
