Plant phenology and seasonal nitrogen availability in Arctic snowbed communities [PDF]

open access: yes, 2006
Thesis (M.S.) University of Alaska Fairbanks, 2006This study was part of the International Tundra Experiment (ITEX) and examined the effects of increased winter snow depth and decreased growing season length on the phenology of four arctic plant species (

Survival and Phenology of \u3ci\u3eAgrilus Planipennis\u3c/i\u3e (Coleoptera: Buprestidae) Reared on a Newly Developed Artificial Diet Free of Host Material [PDF]

open access: yes, 2018
The final phase in the development of an artificial diet that contains no ash host material and the phenology of the emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Bupresidae) on that diet are documented.

Temperature variability homogenized thermal responses in an ectotherm community along a European longitudinal gradient

open access: yesEcography, EarlyView.
Climate change, through rising temperatures, greater variability, and more frequent extremes, is reshaping insect phenology and thermal niches, with profound effects for pest outbreaks. Predicting these impacts requires a clear understanding of species and communities' responses across geographic gradients.

Integrating approaches and methodologies into phenological research in Neotropical dry forests: a systematic review

open access: yesEnvironmental Research Letters
Phenological shifts are increasingly recognized as tangible indicators of plant responses to climate change. Tropical dry forests (TDFs), in particular, are key ecosystems for unraveling the mechanisms driving phenological dynamics, given their crucial ...

Impacts of climate change on rice production in Africa and causes of simulated yield changes [PDF]

open access: yes, 2019
This study is the first of its kind to quantify possible effects of climate change on rice production in Africa. We simulated impacts on rice in irrigated systems (dry season and wet season) and rainfed systems (upland and lowland).

Evaluation of CERES‐Maize Model for Predicting Yield, Evapotranspiration, Water Productivity and Drought Stress Indices Under Center Pivot, Subsurface Drip and Furrow Irrigation Systems With Different Irrigation Levels Simultaneously

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT The effects of different irrigation methods (center pivot [CPI], subsurface drip [SDI] and furrow irrigation [FI]) and levels (full irrigation treatment [FIT], 80% FIT, 60% FIT and rainfed) on yield, crop evapotranspiration (ETc), ET‐water productivity (WPET) and drought stress index for leaf expansion (SIE) and photosynthesis (SIP) of maize ...

Dynamic identification of snow phenology in the Northern Hemisphere [PDF]

open access: yesThe Cryosphere
Snow phenology characterizes the cyclical changes in snow and has become an important indicator of climate change in recent decades. Changes in snow phenology can significantly impact climate and hydrological conditions.

Mulching Increases Water Use Efficiency, Production and Profitability in Forage Cactus–Maize Intercropping Systems

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT This study evaluated the growth, forage production, soil water balance, water indices, biological efficiency and competitive capacity of forage cactus and maize in monoculture and intercropping, with or without mulch. The experiment was conducted in Serra Talhada, Pernambuco, Brazil, using the cactus clone ‘Orelha de Elefante Mexicana’ (OEM ...

Phenological observations and sex ratios in Marchantia chenopoda L. (Hepaticae: Marchantiaceae) [PDF]

open access: yes, 1992
Sex ratios were determined for 15 populations of Marchantia chenopoda L. along Puerto Rico. Sex was determined for twenty randomly selected individuals from each population. A female bias was observed in most populations.
