The 2dF Galaxy Redshift Survey (2dFGRS) is designed to measure redshifts for approximately 250-000 galaxies. This paper describes the survey design, spectroscopic observations, redshift measurements and data base. 2dFGRS uses multifibre spectrograph on Anglo-Australian Telescope, which capable of observing 400 objects simultaneously over a 2° diameter field. source catalogue revised extended version APM galaxy catalogue, targets are galaxies with extinction-corrected magnitudes brighter than...
We present a power-spectrum analysis of the final 2dF Galaxy Redshift Survey (2dFGRS), employing direct Fourier method. The sample used comprises 221 414 galaxies with measured redshifts. investigate in detail modelling selection, improving on previous treatments number respects. A new angular mask is derived, based revisions to photometric calibration. redshift selection function determined by dividing survey according rest-frame colour, and deducing self-consistent treatment k-corrections...
Summary Agriculture represents the dominant land use throughout much of western Europe, and a significant part European biodiversity is associated with this habitat. We attempted to quantify changes in agriculture Britain since 1940s. There have been widespread declines populations many groups organisms farmland north‐west Europe. The particularly marked amongst habitat specialists; taxa still common on are generalists. Farming practices become increasingly intensive post‐war period,...
Summary Increasing concern over the environmental impact of agriculture in Europe has led to introduction agri‐environment schemes. These schemes compensate farmers financially for any loss income associated with measures that aim benefit environment or biodiversity. There are currently 26 out 44 European countries. Agri‐environment vary markedly between countries even within Union. The main objectives include reducing nutrient and pesticide emissions, protecting biodiversity, restoring...
W. C. Allee brought attention to the possibility of a positive relationship between aspects fitness and population size over fifty years ago. This phenomenon, frequently termed effect, has been focus increased interest past two decades in light concerns conservation problems rarity. Use term suffers from absence clear definition however, with result that effects are thought involve only narrow range phenomena often overlooked altogether. We propose for effect attempt resolve major issues...
The Galaxy And Mass Assembly (GAMA) survey has been operating since February 2008 on the 3.9-m Anglo-Australian Telescope using AAOmega fibre-fed spectrograph facility to acquire spectra with a resolution of R~1300 for 120,862 SDSS selected galaxies. target catalogue constitutes three contiguous equatorial regions centred at 9h (G09), 12h (G12) and 14.5h (G15) each 12 x 4 sq.deg limiting fluxes r < 19.4, 19.8, 19.4 mag respectively (and additional limits other wavelengths). Spectra reliable...
We report on our search for microlensing towards the Large Magellanic Cloud (LMC). Analysis of 5.7 years photometry 11.9 million stars in LMC reveals 13 - 17 events. This is significantly more than $\sim$ 2 to 4 events expected from lensing by known stellar populations. The timescales ($\that$) range 34 230 days. estimate optical depth with $2 < \that 400$ days be 1.2 ^{+0.4}_ {-0.3} \ten{-7}$, an additional 20% 30% systematic error. spatial distribution mildly inconsistent LMC/LMC disk...
We combine the Two Micron All Sky Survey (2MASS) Extended Source Catalogue and 2dF Galaxy Redshift to produce an infrared selected galaxy catalogue with 17 173 measured redshifts. use this extensive data set estimate luminosity functions in J- KS-bands.

These derived assuming a...
1. Dispersal is of critical ecological and evolutionary importance for several issues population biology, particularly synchrony, colonization range expansion, metapopulation source–sink dynamics, genetic structure, but it has not previously been possible to compare dispersal patterns across a wide species or study movement outside the confines local areas. 2. Using resampling methods, we verified that statistically unbiased estimates average distance intraspecific variance in could be...
The effects of climate change on biodiversity should depend in part displacement rate (climate-change velocity) and its interaction with species' capacity to migrate. We estimated Late Quaternary glacial-interglacial climate-change velocity by integrating macroclimatic shifts since the Last Glacial Maximum topoclimatic gradients. Globally, areas high velocities were associated marked absences small-ranged amphibians, mammals, birds. association between endemism was weakest highly vagile...
Summary Fundamental ecological research is both intrinsically interesting and provides the basic knowledge required to answer applied questions of importance management natural world. The 100th anniversary British Ecological Society in 2013 an opportune moment reflect on current status ecology as a science look forward high‐light priorities for future work. To do this, we identified 100 important fundamental pure ecology. We elicited from ecologists working across wide range systems...
This paper describes the first catalogue of photometrically-derived stellar mass estimates for intermediate-redshift (z < 0.65) galaxies in Galaxy And Mass Assembly (GAMA) spectroscopic redshift survey. These masses, as well full set ancillary population parameters, will be made public part GAMA data release 2. Although database does include NIR photometry, we show that quality our synthesis fits is significantly poorer when these are included. Further, a large fraction galaxies, parameters...
