Impact of Environmental Conditions on Grass Phenology in the Regional Climate Model COSMO-CLM

open access: yesAtmosphere, 2020
Feedbacks of plant phenology to the regional climate system affect fluxes of energy, water, CO2, biogenic volatile organic compounds as well as canopy conductance, surface roughness length, and are influencing the seasonality of albedo.

Phenological Changes in the Southern Hemisphere

open access: yesPLoS ONE, 2013
Current evidence of phenological responses to recent climate change is substantially biased towards northern hemisphere temperate regions. Given regional differences in climate change, shifts in phenology will not be uniform across the globe, and conclusions drawn from temperate systems in the northern hemisphere might not be applicable to other ...

The essential role of large research vessels in marine ecosystem observations and ocean sustainability

open access: yesLimnology and Oceanography, EarlyView.
Abstract Our understanding of marine ecosystems and ability to manage them sustainably has come from multidisciplinary observations made repeatedly over long periods of time. These long‐term ecosystem observations depend on the capabilities of large research vessels, which play an essential role in the collection of global ocean observations.

How Do Changes in Grassland Phenology and Its Responses to Extreme Climatic Events in Central Asia?

open access: yesLand
Extreme climate events have become more frequent under global warming, significantly affecting vegetation phenology and carbon cycles in Central Asia. However, the mediating effects of intensity of compound drought and heat events (CDHEs) and compound ...

Prolonged low flows and non‐native fish operate additively to alter insect emergence in mountain streams

open access: yesLimnology and Oceanography, EarlyView.
Abstract Climate‐induced flow alteration is decreasing snowpack and advancing snowmelt, subjecting mountain streams to longer low‐flow periods. Yet, anticipating how stream ecosystems respond to prolonged low flows remains challenging because distinct trophic levels can respond differently, and non‐native predators can dampen or amplify responses. Here,

Biotic and thermal drivers alter zooplankton phenology in western Lake Erie

open access: yesLimnology and Oceanography Letters
Environmental change, particularly warming and eutrophication, can alter phenology in aquatic systems. Understanding controls on zooplankton phenology is important due to their central role in food webs.

River metabolism regimes across large environmental gradients

open access: yesLimnology and Oceanography, EarlyView.
Abstract Rivers process up to half of the terrestrial organic carbon before it reaches the oceans, playing an essential role in the global carbon cycle. However, little is known of the seasonal and regional patterns of riverine biological activity as most river ecosystem metabolism studies have been carried out at short spatial and temporal scales.

Sun-spots and Phenology [PDF]

open access: yesNature, 1903
IT can be shown in several ways, I think, that we have, on the whole, in these parts (London), more warmth when the sun-spots are numerous than when they are few, a state of things rather opposite to that in the tropics, where (according to M. Nordmann, who has lately confirmed the work of Dr.

Nutrients on the move: Investigating large scale fatty acid exports from European ponds via emerging insects

open access: yesLimnology and Oceanography, EarlyView.
Abstract Permanent ponds are key landscape units that supply various ecosystem services. Notably, the export of aquatic subsidies to land via emerging insects may significantly influence terrestrial food webs. Polyunsaturated fatty acids (PUFA), which enhance consumer fitness, are among the essential exported components.
