Groundwater Dependency and Hydroclimatic Influences on Riparian and Upland Vegetation Productivity, Upper San Pedro, Arizona, United States

open access: yesHydrological Processes, Volume 40, Issue 3, March 2026.
Remotely sensed vegetation condition is most sensitive to groundwater variability during monsoon seasons, when precipitation is abundant and plants are most productive. Compared to the surrounding uplands, riparian (groundwater dependent) vegetation greenness is more sensitive to vapour pressure deficit, but similarly sensitive to precipitation ...

Novel isolates expand the physiological diversity of Prochlorococcus and illuminate its macroevolution

open access: yesmBio
Prochlorococcus is a diverse picocyanobacterial genus and the most abundant phototroph on Earth. Its photosynthetic diversity divides it into high-light (HL)- or low-light (LL)-adapted groups representing broad phylogenetic grades—each composed of ...

Oxidative costs of migration: infections as an added burden

open access: yesJournal of Avian Biology, Volume 2026, Issue 2, March 2026.
There is increasing evidence that over‐production of reactive species (RS) constitutes a significant physiological cost for migrating birds. The current view entails that RS during migration originate primarily from increased metabolic activity associated with prolonged flights and refueling.

Small dietary changes yield growth benefits in lesser black‐backed gull chicks

open access: yesJournal of Avian Biology, Volume 2026, Issue 2, March 2026.
Global environmental changes alter the availability and predictability of marine resources, forcing marine predators to adapt their diets and foraging strategies. Lesser black‐backed gulls Larus fuscus exhibit individual differences in foraging consistency within and across years, which could influence reproductive success.

How to Define Spacing Among Forest Trees to Mitigate Competition: A Technical Note

open access: yesBiology
Establishing an optimum range of inter-species spacing that reduces competition among trees and mitigates the effects of drought is a critical yet complex challenge in forest management.

¹H NMR Chemical Shifts and J‐Coupling Constants Dependence on Temperature and pH: Implications for the Quantification of Relevant Metabolites

open access: yesNMR in Biomedicine, Volume 39, Issue 3, March 2026.
1H MRS, in combination with quantification methods using model functions based on prior knowledge of chemical shifts and coupling constants, allows the determination of characteristic metabolic processes in healthy and diseased tissue. Using the functional relationships δpHT$$ \delta \left( pH,T\right) $$ and JpHT$$ J\left( pH,T\right) $$ enables this ...

The coordination of dehydration tolerance and avoidance in oaks is mediated by leaf habit across a precipitation gradient

open access: yesFunctional Ecology, Volume 40, Issue 3, Page 750-763, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Forests worldwide are increasingly impacted by drought due to climate change, prompting plants to adapt through dehydration tolerance (DT) and avoidance (DA), two distinct physiological strategies.

Seasonal body mass dynamics mediate life‐history trade‐offs in a hibernating mammal

open access: yesJournal of Animal Ecology, Volume 95, Issue 3, Page 383-396, March 2026.
We tested a suite of ecological hypotheses to explain variation in seasonal body mass dynamics of a fat‐storing mammalian hibernator. We further demonstrated that pre‐hibernation mass gain in ground squirrels mediates an annual allocation trade‐off between current and future reproduction as the squirrels forage and rear young under predation risk ...

Bright and Long: Day Length Modulates the Phenology of Two Myrtaceae Species in Upper Montane Mixed Ombrophilous Forest

open access: yesAustral Ecology, Volume 51, Issue 3, March 2026.
ABSTRACT The Upper Montane Mixed Ombrophilous Forest is a humid montane ecosystem characterised by cold winters and a rich Myrtaceae flora. We investigated the vegetative and reproductive phenology of Myrceugenia euosma (O. Berg) D. Legrand and Siphoneugena reitzii D.

Heat Tolerance and Its Plasticity in Freshwater and Marine Fishes Reflect Exposure to Extremes and Seasonal Variation in Habitat Temperatures

open access: yesEcology Letters, Volume 29, Issue 3, March 2026.
We found that freshwater fishes had higher heat tolerance with greater plasticity than marine fishes, reflecting exposure to higher and more variable temperatures. Accordingly, the benefits of plasticity in terms of time gained for adaptation varied considerably across the globe (5%–35%), with the lowest values for marine species at lower (warmer ...
