Warming and community context drive rapid plant evolution

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Abiotic and biotic factors are important drivers of plant evolution, but how these factors interact to influence plant evolution in multispecies communities is still poorly understood. We performed experimental evolution exposing Brassica rapa plants to a combination of

From moths to microbes: investigating reproductive biology, pollination and nectar in Platanthera Transversa (Suskd.) R.M. Bateman (Orchidaceae)

Journal of Plant Interactions
Platanthera transversa is a common orchid in western North America yet it is poorly studied. This makes it difficult to understand the breadth of pollinators and floral attractant mechanisms present, both of which are vital to understanding the dynamics ...

Energy and water balance in the lesser double-collared sunbird, Nectarinia chalybea [PDF]

, 1999
Bibliography: leaves 164-172.Nectarivores feed on aqueous sugar solutions, and their water balance is tightly linked to their energy balance. When nectar is dilute and energy demands are high, consumption of a large excess of preformed water is ...

Pollen landscape saturation on pollinator bodies reduces pollen deposition by subsequently visited bat‐pollinated flowers

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Sexual selection in flowering plants often operates through male–male competition, yet the mechanisms underlying this phenomenon remain difficult to demonstrate. One potential arena for such competition is pollen placement on pollinators, where pollen grains from ...

Floral reward traits change between sexual phases in two Helleborus species

Scientific Reports
Nectar and pollen attractants as well as visitors in Helleborus viridis ssp. viridis and H. purpurascens (Ranunculaceae), i.e. European species, were studied during two flowering seasons.

Effect of rhizobia and nectar composition on ant interaction in Vicia faba [PDF]

, 2020
Ecological interactions can vary in strength depending on environmental conditions. The outcomes of these interactions are often dependent on the abiotic environment, but can also depend on the presence of other biotic species, including mutualists ...

Pollinator community composition and pollen resource use in calcareous grasslands under different landscape contexts across Europe

Journal of Animal Ecology, EarlyView.
In this paper, we show that pronounced differences in pollinator communities exist between grasslands embedded in contrasting agricultural landscape contexts. Opportunistic foraging strategies of most pollinators resulted in large interaction turnover, but these shifts did not translate into major changes in overall network structure, most likely as a ...

NECTAR-PRODUCING PLANTS AND CROP ROTATION: IMPACTS ON POLLINATORS AND YIELD IN HADYACH UTC, UKRAINE

Environmental Problems
This study examined the composition, phenology, and ecological significance of nectar-producing flora in the agricultural landscapes of the Hadyach Urban Territorial Community (UTC), Poltava region, Ukraine. A total of 78 species, including native trees,

Optimising daily sampling of plant–bee interaction networks

Journal of Animal Ecology, EarlyView.
Daily variation in ecological interaction networks is rarely quantified due to limited temporal sampling, yet network structure may change substantially within a single day. We show that plant–bee networks exhibit strong intraday shifts in composition and structure, and that sampling distributed across key daily periods better captures network ...

Niche occupancy of Jamaican bat caves: Diversity increases isotopic niche packing

Journal of Animal Ecology, EarlyView.
Tropical bat caves are home to hundreds of thousands of bats of multiple species. In Jamaica, we found that isotopic niche packing is the likely mechanism of coexistence at more diverse sites. Abstract There are over 1000 documented caves across Jamaica, many of them used by diverse communities of bats.
