Leveraging machine learning and citizen science data to describe flowering phenology across South Africa

PLANTS, PEOPLE, PLANET, EarlyView.
Recent shifts in flowering times are an index of, and a response to, human driven climate change. However, most information on these flowering changes is heavily skewed to the northern hemisphere. This imbalance limits our understanding of how climate change is affecting ecosystems, including the mismatches of flowering times between species, increased

Trophic niche characterization of zooplankton and planktivorous fish: a comparative approach using stable isotopes in bulk and amino acid samples

Frontiers in Marine Science
Quantification of the size and overlap of trophic niches of species with similar diets is crucial to understand food web dynamics. However, there are difficulties in determining all food resources used by each species over time and resolving competition ...

A closer look at the main actors of Neotropical floodplain food webs: functional classification and niche overlap of dominant benthic invertebrates in a floodplain lake of Paraná River

Iheringia: Série Zoologia, 2016
Functional classification of animals is necessary to enhance the predictive power of food web models. However, while there is a large database for functional classification of benthic invertebrates (Functional Feeding Groups, FFG) in the temperate zone ...

Diet Switching and Interspecific Competition in Sympatric Steppe Ungulates Under Seasonal Resource Variability. [PDF]

Ecol Evol
ABSTRACT Understanding the mechanisms of competition and coexistence among sympatric species is crucial for deepening our understanding of interspecific interactions and informing the conservation of rare and endangered wildlife. In this study, we utilized DNA macro‐barcoding technology to analyze the seasonal dietary habits of Kiang (Equus kiang) and ...

Solar farms can mitigate negative impacts of whiplash weather on plant communities in a dryland ecosystem

PLANTS, PEOPLE, PLANET, EarlyView.
Utility‐scale solar energy (USSE) development generates novel questions regarding coupling clean energy production with terrestrial ecosystem services (e.g., forage production, pollinator support). We found that a USSE array sited in a fallowed cropland maintained a reseeded native plant community even a decade post‐restoration and that the array ...

Swimming with the giant: coexistence patterns of a new redfin minnow Pseudobarbus skeltoni from a global biodiversity hot spot

Ecology and Evolution, 2016
Ecological niche theory predicts that coexistence is facilitated by resource partitioning mechanisms that are influenced by abiotic and biotic interactions.

Unraveling the impact of dog‐friendly spaces on urban–wildland pumas and other wildlife

Wildlife Biology, EarlyView.
As the most widespread large carnivore on the planet, domestic dogs Canis lupus familiaris can pose a major threat to wildlife, even within protected areas (PAs). Growing human presence in PAs, coupled with increasing pet dog ownership underscores the urgency to understand the influence of dogs on wildlife activity and health.

Characteristics of the diet of the western barn owl and the little owl in the Zakarpattia Oblast (Ukraine)

Theriologia Ukrainica
The article presents the results of an analysis of approximately 150 pellets (containing 178 food items) of the Little Owl (Athene noctua) and about 300 pellets (containing 1,268 food items) of the Barn Owl (Tyto alba) collected in the Berehove District,

Differences in Dietary Composition and Interspecific Competition Among Large Carnivores on the Qinghai-Xizang Plateau. [PDF]

Ecol Evol
This study elucidated the mechanisms underlying regional coexistence among the snow leopard (Panthera uncia), wolf (Canis lupus), and brown bear (Ursus arctos) through the analysis of their trophic niches. The findings provide a scientific foundation for further investigation into the mechanisms that maintain carnivore communities in high‐altitude ...
