Interactive Effects of Arbuscular Mycorrhizal Fungi and Copper Stress on Flowering Phenology and Reproduction of Elsholtzia splendens.

open access: yesPLoS ONE, 2015
Plant responses to heavy metal contamination may depend on the presence of arbuscular mycorrhizal fungi (AMF). Elsholtzia splendens is an indicator species for the presence of copper (Cu) mines because both its flowering phenology and reproduction are ...

VARIATION IN FLOWERING PHENOLOGY OF CASSIA FISTULA LINN. POPULATION IN OTA, OGUN STATE. NIGERIA [PDF]

open access: yes, 2016
Flowering phenology in the population of Cassia fistula Linn. at Ota, Ogun State, Nigeria was investigated for three years to determine if there was variation in the phenology and the patterns were compared with some environmental factors to determine ...

Flowering phenology of Campanula on Mt Olynipos, Greece

open access: yesEcography, 2001
We studied the fowering phenology of the genus Campanula (represented by nine species) along the elevation gradient of Mt Olympos (Greece) in order to assess whether there are elevation patterns at the genus level and whether these relate to patterns previously observed along such gradients at the community level.

Selection for persistence of endophyte‐free meadow fescue under intensive grazing versus frequent mowing

open access: yesGrassland Research, EarlyView.
Cattle grazing meadow fescue pasture in remnant oak savanna near Fennimore, Wisconsin. Abstract Background Meadow fescue (Schedonorus pratensis (Huds.) P. Beauv.) is highly adapted to managed rotational grazing systems with sufficient rest periods to promote regrowth and sward longevity.

Escape from floral herbivory by early flowering in Arabidopsis halleri subsp. gemmifera [PDF]

open access: yes, 2018
Natural selection on flowering phenology has been studied primarily in terms of plant-pollinator interactions and effects of abiotic conditions. Little is known, however, about geographic variation in other biotic factors such as herbivores and its ...

Urbanization, environmental stabilization and temporal persistence of bird species: A view from Latin America [PDF]

open access: yes, 2018
Background. A scarcely studied consequence of urbanization is the effect of temporal stabilization of the environment on bird communities. This alteration is thought to dampen environmental variations between day and night, seasons and years, promoting a

Compound Hot‐Dry Days (CHDDs) and Their Implications on Maize Yields in the Free State Province, South Africa

open access: yesInternational Journal of Climatology, EarlyView.
Compound hot‐dry events occurring during the maize growing period are increasing significantly (p < 0.05) with time, with the median values ranging from 93 to 120 days. El Niño Southern Oscillation (ENSO) influences the variability of compound hot‐dry events with high significance (p < 0.05) positive Pearson correlation.

Reproductive biology of "Helianthemum apennium" (L.) Mill. and "H. caput-felis" Boiss. (Cistaceae) from Mallorca (Balearic Island, Spain) [PDF]

open access: yes, 1997
El estudio de la biología reproductiva de poblaciones naturales de Helianthemum apenninum y H. caput-felis en Mallorca ha demostrado que son básicamente entomófilos, aunque también producen numerosos frutos por auto-polinización. Las flores de H.

Delayed chilling appears to counteract flowering advances of apricot in southern UK [PDF]

open access: yes, 2017
Temperatures are rising across the globe, and the UK is no exception. Spring phenology of perennial fruit crops is to a large extent determined by temperature during effective chilling (endo-dormancy) and heat accumulation (eco-dormancy) periods.
