Developing a macroecology for human‐altered ecosystems

open access: yesEcography, EarlyView.
Although anthropogenically‐induced ecological disruptions are fundamentally important in defining ecosystem properties, they are largely overlooked by macroecological theory. Anthropogenic disruptions and their effects are generally not comparable to one another, nor to disturbances that are part of natural disturbance regimes.

Allometric Relationships in the Green Mussel, Perna viridis L. [PDF]

open access: yes, 1980
224-226Allometric relationships between length, height, depth and weight in Perna viridis, collected from Narakkal Coast, Cochin, Kerala, India, showed that in the case of length-height and length-depth relationships, the slopes of the smaller size group

PondNet – towards a global network of experiments on the effects of climate change on aquatic ecosystems

open access: yesEcography, EarlyView.
Global change is reshaping the distribution of biodiversity and the functioning of ecosystems. Predicting the long‐term consequences of such changes remains a challenge due to a need for a clear understanding of the mechanisms underpinning ecosystem‐level responses, as well as the role of geographical and environmental contingencies.

Overcoming obstacles to sharing data on tree allometric equations

open access: yes, 2017
Advances in ecology face the complexity of ecosystems with dynamics longer than a single scientist’s career. In forestry and REDD+ practice, in particular, our ability to understand forest ecosystem dynamics and to manage them for mitigation and adaptation strongly relies on the combination of long-term research efforts and on data sharing.

Periodontitis and its association with left ventricular geometry and function: A cross‐sectional study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background This study investigated the cross‐sectional association between periodontal status and left ventricular (LV) geometry and function, an early and prognostically relevant marker of cardiovascular disease. Methods Data were drawn from two population‐based cohorts in the Study of Health in Pomerania (SHIP): SHIP‐START‐2 (N = 2333) and ...

Species-specific allometric models for reducing uncertainty in estimating above ground biomass at Moist Evergreen Afromontane Forest of Ethiopia

open access: yesScientific Reports
An allometric equation is used to convert easily measured tree variables into biomass. However, limited species-specific biomass equations are available for native tree species grown in various biomes of Ethiopia. The available pantropic generic equation

Yield‐Dependent Allocation Functions Overestimate Root‐Derived Carbon Inputs in Wheat and Maize

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Root‐derived carbon (C) inputs for wheat and maize were estimated using the yield‐based allocation functions of Bolinder et al. and Jacobs et al. Comparison with measured root C showed systematic overestimation that becomes larger as predicted C increases.

Biomass Carbon in Harvest Residues of Winter Oilseed Rape Across Fertilizer N Rates: Implications for Carbon Input Estimations in Soil Carbon Models

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Reliable estimation of carbon (C) inputs from above‐ and belowground residues at different yield levels is crucial, as these inputs drive soil organic carbon (SOC) models for C accounting. Aims: This study quantifies C inputs from different components of winter oilseed rape (WOSR) and compares them with estimates from various ...

Fruit use and fruit processing by euphonias, specialized avian frugivores

open access: yesOikos, EarlyView.
Euphonias (Neotropical passerines in the genera Euphonia and Chlorophonia) form the quintessential example of a specialized avian frugivore, combining a high reliance on fruit as food and the restriction of fruit taxa exploited. To understand their specialization, we explored the integration of fruit morphological and nutritional traits with their ...
