Summary: Species with different life histories and communities tend to shift their phenology in response to climate warming, leading to increased phenological overlap and potential impacts on species interactions such as resource competition. Shifts in abundance distributions are not strongly influenced by species' seasonal timing or elevations, but phenological overlap increases in warmer years as species adjust their seasonal timing. Overall, grasshopper abundance is relatively robust to climate changes, but increased phenological overlap may decrease abundance by strengthening species interactions.

Summary: Research indicates that Eastern North American monarch butterflies are showing a significant delay in migration timing, which may be related to warming temperatures. While there is no significant change in population at the study location, data from overwintering sites in Mexico show a substantial decline in monarch abundance over the same period.

Summary: This study tested the suitability of non-checklist data for estimating key figures of migration phenology in Finland and found that it successfully revealed latitudinal migration progression. Non-checklist data proved to be well suited for determining descriptors of migration phenology in Northern Europe, which are challenging to attain through other means. The spatiotemporal coverage of non-checklist data makes it a valuable complement to current migration databases from bird observatories. Additionally, species-specific descriptors of migration phenology derived from non-checklist data have potential applications in climate change studies and radar ornithology.

Summary: This study examines the changing climate and timing of fall foliage in Acadia National Park, Maine, and predicts future changes. The results show significant increases in temperatures and precipitation, leading to a delay in the timing of peak fall foliage. Understanding the impact of climate on leaf senescence is crucial for sustainable planning in the park.

Summary: Climate change has caused phenological shifts in different species and trophic levels, with a recent slowdown in the rate of advance due to a decrease in late spring temperatures. It is projected that prey phenology will advance faster than predator phenology in the coming decades, intensifying phenological mismatches.

Summary: This study investigated leaf-fall phenology and seasonal dynamics of canopy nutrient concentration in a temperate deciduous broadleaved forest in northeastern China. The results show that estimating canopy nutrient fluxes and resorption efficiency using litterfall collected at the day of year (DOY) of peak leaf-fall can lead to non-negligible errors, and species-specific combined litterfall collected at and slightly before the DOY of peak leaf-fall may be a better metric.

Summary: This study investigated the reproductive seasonality of the mandrill, a social primate endemic to the Congo basin. The study found that foraging time varied seasonally, especially for subordinate females. Birth timing was found to be plastic, with females giving birth year round, but birth within the birth peak resulted in shorter interbirth intervals and lower probability of miscarriage. Reproductive history and social rank also influenced birth timing within and between individuals.

Summary: The soil EC can be predicted using smartphone-based color coordinates and different spectra. The highest prediction accuracy was achieved by combining the Vis-NIR and pXRF spectra. The smartphone-based digital images based on the 2D-CNN model and combining Vis-NIR + pXRF spectra with the GRU model were recommended for accurate prediction.

Summary: This study explored the effect of different illumination levels on the prediction accuracy of soil organic carbon (SOC) using smartphone-based digital images. Lower illumination levels improved the prediction accuracy of SOC content, with the random forest model achieving relatively high accuracy (r2 = 0.42 to 0.70) under 300 lx illumination level. The a*, R, and H color parameters were the best variables for predicting SOC in the 300 lx dataset.

Summary: Utilizing a combination of VIs and color moments from UAV-based imagery can improve the accuracy of estimating plant nitrogen concentration, showing better performance compared to using VIs or color moments alone. This highlights the significant contribution of color moments in enhancing PNC estimation accuracy, indicating the great potential of the RGB-VIs and color moments combination for rice PNC estimation.

Summary: Intraspecific trait variation plays a significant role in species interactions and community composition. Developmental stage, as a major source of intraspecific trait variation, is often neglected in ecological studies. In this article, we explore the role of time in the ecology of intraspecific trait variation, specifically focusing on plants and their interactions with other organisms. Considering the timing of trait variation within a population becomes crucial in structuring trait-mediated ecological interactions and community processes.

Summary: This study compared eight color normalization algorithms for AI-based classification of H&E-stained histopathology slides, finding that while color normalization does not consistently improve classification on single-center data, it significantly enhances accuracy on multi-center datasets. Introducing a novel augmentation strategy by mixing color-normalized images using three algorithms consistently improves diagnosis of test images from external centers, showing the potential for reliable color normalization in AI-based digital pathology diagnosis of cancers from multiple centers.

Summary: The study focused on analyzing banana quality and ripening stages at different temperatures using a smartphone camera and an artificial neural network (ANN). The relationship between color features extracted from images and chemical/physical properties of bananas was examined. The ANN models efficiently predicted firmness and TSS of bananas, but were less accurate in predicting pH value and ratio of pulp to peel. The study demonstrated a potential post-harvest method using smartphone cameras and ANN to estimate banana quality during ripening.

Summary: Canopy structure plays a crucial role in the energy budget of grassland ecosystems and is influenced by plant diversity. Functional group composition (herbs vs. grass dominance) and to a lesser extent, plant diversity, drive the mean and variation of canopy surface temperature. These effects are mediated by metrics of canopy structure as well as direct effects unrelated to structural metrics.

Summary: This study examined the effects of vegetation cover and land-cover variance on biodiversity, finding a transition from low to high variance with decreasing vegetation cover. It predicted a unimodal relationship between species richness and anthropization, indicating a threshold where the positive effects of land-cover variance are outweighed by the negative effects of vegetation cover loss. Identifying these thresholds could be crucial for setting conservation targets at a landscape scale.

Summary: The alteration of environmental conditions leads to population decline of common species and extinction of rare species. The study demonstrates how rank abundance distribution (RAD) models can predict species richness based on the dominance of the most abundant species and the total number of individuals in a community. The results highlight a trade-off between species richness and dominance, suggesting that withdrawing individuals from abundant populations might help conserve species richness. However, negative consequences such as habitat destruction or bycatches need to be considered.

Summary: The study found that the growing season phenology of wetlands is mainly influenced by the plant assemblages, rather than the species richness of individual communities. The variation in growing season length of wetlands reflects the destabilizing effect of climatic and edaphic factors on green-up dates, while the diversity of plant assemblages has a dampening effect on green-down dates.

Summary: Phenology monitoring is important for understanding forest functioning and climate impacts. This research compares the phenological behavior of European beech forests using Tree-Talker (TT+) and Sentinel 2 satellite data. The study finds differences in the information derived by the two sensor types, particularly in terms of season length, phenology changepoints, and leaf period variability. TT+ with its higher temporal resolution demonstrates precision in capturing the phenological changepoints, especially when satellite image availability is limited.
