Biomass production and nitrogen content of C3- and C4- grasses in pure and mixed culture with different nitrogen supply
Oecologia - - 1987
Is there a feedback between N availability in siliceous and calcareous soils and Cistus albidus leaf chemical composition?
Oecologia - Tập 136 Số 2 - Trang 183-192 - 2003
Generalist birds govern the seed dispersal of a parasitic plant with strong recruitment constraints
Oecologia - Tập 176 - Trang 139-147 - 2014
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 ......
Individual and interactive effects of chronic anthropogenic disturbance and rainfall on taxonomic, functional and phylogenetic composition and diversity of extrafloral nectary-bearing plants in Brazilian Caatinga
Oecologia - Tập 198 - Trang 267-277 - 2021
Chronic anthropogenic disturbance (CAD) and climate change represent two of the major threats to biodiversity globally, but their combined effects are not well understood. Here we investigate the individual and interactive effects of increasing CAD and decreasing rainfall on the composition and taxonomic (TD), functional (FD) and phylogenetic diversity (PD) of plants possessing extrafloral nectari......
Flowering phenology in the central highland of Iceland and implications for climatic warming in the Arctic
Oecologia - Tập 114 - Trang 43-49 - 1998
The cool and short growing season that characterizes Arctic climates puts severe constraints on life cycles and reproduction in the Arctic flora. The timing of flowering is particularly critical and may affect both breeding system and reproductive success through the heavy penalties associated with later flowering. An 11-year study of 75 species in the central highland of Iceland showed that the ......
Foraging in groups affects giving-up densities: solo foragers quit sooner
Oecologia - Tập 178 - Trang 707-713 - 2015
The giving-up density framework is an elegant and widely adopted mathematical approach to measuring animals’ foraging decisions at non-replenishing artificial resource patches. Under this framework, an animal should “give up” when the benefits of foraging are outweighed by the costs (e.g., predation risk, energetic, and/or missed opportunity costs). However, animals of many species may forage in g......
Wood biomass, production and litter-fall in an English beechwood
Oecologia - Tập 57 - Trang 189-195 - 1983
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......
Leaf diseases drive the Janzen–Connell mechanism regardless of light conditions: a 3-year field study
Oecologia - Tập 183 - Trang 191-199 - 2016
In forests, negative density/distance-dependent seedling mortality (NDD) caused by natural enemies plays a key role in maintaining species diversity [Janzen–Connell (J–C) model]. However, the relative importance of natural enemies in mediating NDD under heterogeneous light conditions has remained unclear. We examined the relative importance of pathogens (i.e., soil pathogens, leaf diseases) on see......
