Plant Biology, EarlyView.Drought stress leads to reduced nectar secretion and alters nectar composition of day‐ and night‐flowering Nicotiana species, which may impair plant–pollinator interactions. Abstract The frequencies of droughts worldwide will increase in the future due to climate changes. Nectar composition of plant species varies in relation to pollinator and can also

Resilience of floral scent emission after florivory
Plant Biology, EarlyView.Florivory is thought to affect floral traits, impacting pollination. However, our data suggest a stability in post‐florivory scent emission, which may guarantee the maintenance of pollinator visitation regardless of florivory, indicating a resilience of natural systems with multiple and simultaneous interactions. Created in BioRender. Tunes, P.

Genetic Toolkit for Assessment and Prediction of Population-Level Impacts of Bridge Construction on Birds [PDF]
, 2020 Recent studies have highlighted alarming rates of declines in bird populations across the country. The State of California is home to over 650 resident and migrant avian species. Legislation for protecting these species has existed for over a century now,

Treating hummingbirds as feathered bees : a case of ethological cross-pollination [PDF]
, 2017 Hummingbirds feed from hundreds of flowers every day. The properties of these flowers provide these birds with a wealth of information about colour, space and time to guide how they forage.

Biological Reviews, Volume 101, Issue 2, Page 911-925, April 2026.ABSTRACT Three categories of explanations exist for why we age: mechanistic theories, which omit reference to evolutionary forces; weakening force of selection theories, which posit that barriers exist that prevent evolutionary forces from optimising fitness in ageing; and optimisation theories, which posit that evolutionary forces actually select for ...

Acta Botânica Brasílica, 2015 We studied the pollination biology of Canna paniculata (Cannaceae), a plant species common in the Atlantic Rainforest of southeastern Brazil. The species presents specialized ornithophilous flowers, which in our study area are solely pollinated by the ...

Respiratory Evaporative Water Loss During Hovering and Forward Flight in Hummingbirds
, 2012 Hummingbirds represent an end point for small body size and water flux in vertebrates. We explored the role evaporative water loss (EWL) plays in management of their large water pool and its use in dissipating metabolic heat.

Evaluating cultivars for pollinator gardens
Ecosphere, Volume 17, Issue 4, April 2026.Abstract Pollinator gardening is a rapidly growing community‐based conservation movement, yet evidence‐based guidelines for practice are largely missing. In particular, it is unclear whether cultivars of flowering plants (i.e., horticultural varieties)‐can support pollinators as effectively as their wild‐type counterparts.
