Spatial trends of Potamogetonaceae along an altitudinal gradient

open access: yesBiologia, 2020
Studying the effect of altitude on species distribution may help us to predict the response of species to future climate changes, which will likely cause upward migration of vegetation zones. In this study, we aimed to analyze distribution and abundance patterns of Potamogetonaceae along an altitudinal gradient and to determine the species ...

Macrophage PABPC4‐SPP1 Axis Orchestrates Immunosuppression in Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
In the CRC microenvironment, macrophage PABPC4 binds to the 3′UTR of SPP1 mRNA to stabilize its expression, thereby sustaining M2‐like immunosuppressive macrophage polarization. Concurrently, this axis suppresses CD8+ T cell effector functions via CD44 signaling, collectively fostering an immunosuppressive niche that drives tumor progression.

Biodiversity and Altitudinal Variation of Dung Beetles (Scarabaeidae: Scarabaeinae) in the Oglán Alto Watershed, Ecuadorian Amazon

open access: yesActa Zoológica Lilloana
Dung beetles are considered a useful taxon to describe and to monitor spatial and temporal patterns of biodiversity. Tropical communities of dung beetles are usually diverse, abundant, and habitat specific; they respond quickly to many types of ...

Low Latency Global Carbon Budget Reveals Late 2024 Carbon Losses and Contrasting Early 2025 Land Sink Recovery Signals

open access: yesAdvanced Science, EarlyView.
Low latency carbon budget estimates for July 2024–June 2025 combine atmospheric CO2 growth rates, fossil emissions, ocean uptake, DGVM land fluxes, and OCO‐2 inversions. The budget shows that late‐2024 land carbon losses dominate the annual anomaly, while early‐2025 recovery differs between bottom‐up models and top‐down inversions, especially in ...

Widespread phenotypic and genetic divergence along altitudinal gradients in animals [PDF]

open access: yesJournal of Evolutionary Biology, 2013
AbstractAltitudinal gradients offer valuable study systems to investigate how adaptive genetic diversity is distributed within and between natural populations and which factors promote or prevent adaptive differentiation. The environmental clines along altitudinal gradients tend to be steep relative to the dispersal distance of many organisms ...
