Net ecosystem exchange, gross primary production, ecosystem respiration and net biome production of full crop rotations in Europe

open access: yes, 2009
Crop rotations are important elements of agricultural management in many regions of Europe. Since the different crops result in different carbon input into the soils, a realistic carbon balance for agricultural ecosystems under crop rotation can only be derived when a full rotation is considered.

T. rex cognition was T. rex‐like—A critical outlook on diverging views of the neurocognitive evolution in dinosaurs

open access: yesThe Anatomical Record, EarlyView.
Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

Assessing the Carbon Budget Dynamics of Terrestrial Ecosystems in the Amur River Basin

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
In the context of climate change, understanding the carbon cycle of terrestrial ecosystem is important for projecting the future climate. Toward this end, it is essential to determine the roles of different terrestrial ecosystems as either carbon sources

Effects of processes at the population and community level on carbon dynamics of an ecosystem model [PDF]

open access: yes, 2008
Ecological processes at the population and community level are often ignored in biogeochemical models, however, the effects of excluding these processes at the ecosystem level is uncertain. In this study we analyzed the set of behaviors that emerge after

The macroeconomic cost of catastrophic pollinator declines [PDF]

open access: yes, 2016
We develop a computable general equilibrium (CGE) approach to assess the macroeconomic impacts of productivity shocks due to catastrophic losses of pollination ecosystem services at global and regional scales.

Gleaning the Rocky Shore? 2500 Years of Coastal Resource Use at Red Bluff 1, GunaiKurnai Country, SE Australia

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT Shell middens in Gippsland along the eastern half of Victoria's coastline have usually been characterised as small, short‐duration camp sites with relatively low shell densities and low taxonomic diversity. Here we present new excavation results from a dense, high‐diversity site at Red Bluff near the eastern end of GunaiKurnai Country, a ...

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

open access: yesAnimal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.
