Depleted Dissolved Oxygen Concentrations Impair the Embryonic and Early Larval Development of Eastern Hellbenders (Cryptobranchus alleganiensis)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Depletion of dissolved oxygen (DO; hypoxia) and its influence on sensitive fauna and vulnerable life stages is an emerging concern in lotic freshwater ecosystems. A species particularly vulnerable to hypoxia is the Eastern Hellbender—a large‐bodied, fully aquatic salamander which relies on cutaneous respiration and has evolved to thrive in ...

Changes in forest ecosystem stability under climate change in a temperate landscape

Frontiers in Forests and Global Change
Climate change poses significant threats to forests globally. Understanding the relationship between environmental variables and species distribution is crucial for evaluating the vulnerability of tree species assemblies to anticipated climate change ...

Response of leaf area and dry matter of crop, weeds and cover crops to competition and fertilizer resources

Acta Agriculturae Slovenica, 2014
Plasticity of plants to allocate leaf area and dry matter to upper layer of canopy play important role in canopy architecture and competition. In order to study the vertical distribution of leaf area and dry matter of corn (Zea mays L.), cover crops and ...

The Art of Reception: Field Visits as Microcosms for Development Interventions of Non‐Governmental Organisations in Uganda

Journal of International Development, EarlyView.
ABSTRACT Field visits are common phenomena with non‐governmental organisations in Uganda. During these visits, Ugandan national staff guide visitors on series of meetings and interactions in the field. Following an actor‐oriented approach and drawing on ethnographic data on 14 field visits, this paper understands the field visit as a microcosm for the ...

Random forests and stochastic gradient boosting for predicting tree canopy cover: Comparing tuning processes and model performance

, 2016
As part of the development of the 2011 National Land Cover Database (NLCD) tree canopy cover layer, a pilot project was launched to test the use of high-resolution photography coupled with extensive ancillary data to map the distribution of tree canopy ...

Geochronology of the Whittlesey sedimentary succession, eastern England: The ‘Pompeii’ of the British late Middle Pleistocene to Holocene record

Journal of Quaternary Science, EarlyView.
Abstract The sedimentary succession at Whittlesey preserves a unique British late Middle Pleistocene to Holocene record back to a time equivalent to at least marine oxygen isotope stage 8 (ca. 250 ka). This study builds on previously published sedimentology, geochronology and palaeoecology results to establish 20 sedimentary facies associations, with ...

Integrated characterization of Greek fennel genotypes through morpho‐agronomical characteristics, yield components and phytochemical compounds

JSFA reports, Volume 5, Issue 3, Page 91-103, March 2025.
Abstract Background Fennel (Foeniculum vulgare Mill.) is a widely cultivated vegetable and aromatic‐medicinal plant. In this research, field studies assessed 12 fennel genotypes of diverse origin, comprising 10 Greek accessions and two European commercial varieties, focusing on their morpho‐agronomical traits, phenolic compounds and antioxidant ...
