Most young leaves pale in comparison to mature leaves: delayed greening is neither binary nor tropical

Ecography, EarlyView.
Delayed greening, the phenomenon in which expanding leaves appear red, blue or pale green due to low chlorophyll content, has long intrigued ecologists. However, little is known about what type of species are most likely to delay greening or which environmental conditions are associated with delayed greening.

Environmental and local habitat variables as predictors of trophic interactions in subtidal rocky reefs along the SE Pacific coast

Ecography, EarlyView.
Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.

Comparisons of the Orbiting Carbon Observatory-2 (OCO-2) X CO 2 measurements with TCCON

, 2016
NASA's Orbiting Carbon Observatory-2 (OCO-2) has been measuring carbon dioxide column-averaged dry-air mole fraction, X_(CO_2), in the Earth's atmosphere for over 2 years.

Shape‐shifting in relative wing length of juvenile shorebirds: no evidence of developmental temperatures driving morphological changes

Ecography, EarlyView.
Morphological changes concurrent with climate change are increasingly identified in birds, often through decreasing body size and increasing appendage size. Such changes could have thermoregulatory implications, through the improved surface area to body ratio they provide.

COMPARATIVE ANALYSIS OF GEOMAGNETIC DISTURBANCES IN THE ODESSA MAGNETIC ANOMALY AREA IN THE 24TH SOLAR ACTIVITY CYCLE

Radio Physics and Radio Astronomy, 2019
Purpose: The main oscillation periods of the geomagnetic field perturbation level in the Odesa magnetic anomaly area are studied by the data observed at the “Odesa” geomagnetic observatory within the 24th solar activity cycle.

Winners, Losers, and the Implications of Inequality in Biodiversity Conservation Policies: Insights From European Development Aid to Central Africa

Environmental Policy and Governance, EarlyView.
ABSTRACT International aid for biodiversity conservation is expected to provide alternative livelihoods for forest‐dependent communities to offset restrictions on forest use. This aligns with the contemporary conservation discourse that promotes pro‐poor, human rights‐based, and sustainability principles.
