Nitrogen Fertilization in maize using the Portable Chlorophyll Meter

open access: yes, 2009
The cultivation of maize is one of the most important crops for the the Brazilian Agribusiness, representing 6.4% of world production. It should be noted that world production is almost 800 million tons and the United States is responsible for 42% of total production.

Regional Sustainable Economic Development in the Caribbean? A Discursive Inquiry

open access: yesSustainable Development, EarlyView.
ABSTRACT The Caribbean region is governed by several regional bodies. Among the more important organizations for small island states, where coral reefs and ocean conservation are paramount, is the Caribbean Community (CARICOM). Currently, the region is going through critical environmental changes that bring important vulnerabilities.

Media‐Dependent Growth, Stress Responses, and Metal Accumulation Patterns in Azolla imbricata (Roxb.) Nakai Exposed to As, Cd, Cu, Pb, and Zn: Individual and Combination Effects (Synergistic, Antagonistic, and Additive)

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT In this study, we examined metal accumulation and biochemical responses of Azolla imbricata (Roxb.) Nakai exposed to water medium (WM) and nutrient medium (NM) under single and combined (co‐exposure) treatments with five metals (As, Cd, Cu, Pb, and Zn) at 10% environmentally relevant concentrations.

Future climate change favours the increase in abundance of smaller, shorter‐lived fish in the northeastern Mediterranean

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract As species distributions shift due to climate change, functional alterations may also occur within marine communities, potentially leading to ecosystem‐wide transformations.

Multi‐gradient warming reshapes functional traits and adaptive responses of alpine meadow plants

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant functional traits in alpine meadows are critical indicators of ecosystem responses to climate warming, yet dynamic changes in trait networks across warming gradients and their consequences for community functions remain poorly understood.

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state

open access: yesJournal of Animal Ecology, EarlyView.
The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Waterbird zoogeochemical effects shape wetland nutrient dynamics and algal communities in Laurentian Great Lakes coastal freshwater wetlands

open access: yesJournal of Animal Ecology, EarlyView.
Distinct waterbird species influence nutrient cycling through guano contributions in Great Lakes coastal wetlands. Waterbird‐derived nutrients favour distinct algal communities and wetland sediments rapidly remove waterbird nutrients via biogeochemical processes.

Rapid non‐destructive assessment of leaf water status with low‐cost transmittance meters

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Tools for more efficiently managing agricultural production and the use of limited water resources are required in the context of a growing global population, while the increasing threat posed by droughts and wildfires necessitates improved methods for risk assessment, forecasting and early warning. Quantifying leaf water content is central to

Co‐Culture of Mammalian Cells and Photosynthetic Microorganisms for Oxygen Supply in Engineered Tissues

open access: yesCell Proliferation, EarlyView.
Continuous 28‐day light exposure alters behaviours of articular cartilage progenitor cells (ACPCs) and mesenchymal stromal cells (MSCs). Co‐culture with Leptolyngbya and Synechococcus does not adversely affect the chondrogenic capacity of ACPCs over a 28‐day period, in contrast to co‐culture with Chlorella.

Attractiveness of Melon Genotypes to Whitefly (Bemisia tabaci) Mediated by Foliar Morphological and Biochemical Traits

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
This study identifies melon genotypes resistant to Bemisia tabaci by integrating morphological and biochemical leaf traits. Using free‐choice and no‐choice assays, we demonstrate that resistance is primarily mediated by antixenosis. Genotypes CNPH 11‐1071‐43, CNPH 06‐1047‐343, CNPH 13‐1076, and BG MEL 16 significantly reduced whitefly settling and ...
