Generalist birds govern the seed dispersal of a parasitic plant with strong recruitment constraintsOecologia - Tập 176 - Trang 139-147 - 2014
Ana Mellado, Regino Zamora
Mistletoes constitute instructive study cases with which to address the role of generalist consumers in the study of plant–animal interactions. Their ranges of safe sites for recruitment are among the most restricted of any plant; therefore, frugivores specializing in mistletoe have been considered almost indispensable for the seed dispersal of these parasitic plants. However, the absence of such ...... hiện toàn bộ
Wood biomass, production and litter-fall in an English beechwoodOecologia - Tập 57 - Trang 189-195 - 1983
J. Phillipson
Studies of productivity in a 160 yr old beechwood growing on a basic soil did not reveal any marked, or inexplicable, differences from similar aged European beech forests growing on acid soils. Total above-ground wood biomass was equivalent to 44,897 g d.wt. m-2 (live wood biomass accounting for 42,322 g). Bole biomass equalled 28,595 g m-2 (live tree contribution, 26,755 g). Branch and twig bioma...... hiện toàn bộ
Coexisting living stromatolites and infaunal metazoansOecologia - Tập 182 - Trang 539-545 - 2016
Gavin M. Rishworth, Renzo Perissinotto, Matthew S. Bird
Microbialites, bioaccretionary structures formed during the growth and metabolism of microorganisms (principally cyanobacteria) were the dominant lifeform in shallow late-Archean and Proterozoic oceans. During the Cambrian radiation of metazoan life, which began ~540 Mya, microbialite abundance and diversity further declined following a peak in the Mesoproterozoic. Notwithstanding contention, graz...... hiện toàn bộ
