Dimorphic enantiostyly and its function for pollination by carpenter bees in a pollen‐rewarding Caribbean bloodwort

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Geographical, temporal, and individual‐based differences in the trophic ecology of female Cape fur seals

open access: yesEcology and Evolution, 2023
Information on resource use and trophic dynamics of marine predators is important for understanding their role in ecosystem functioning and predicting population‐level responses to environmental change.

Assessing the role of dispersed floralresources for managed bees in providingsupporting ecosystem services for croppollination [PDF]

open access: yes, 2018
Most pollination ecosystem services studies have focussed on wild pollinators and their dependence on natural floral resources adjacent to crop fields. However, managed pollinators depend on a mixture of floral resources that are spatially separated from

Phylogenomics reveals the evolution of floral traits associated with pollinators and pollinator–prey conflict within the carnivorous Pinguicula subgenus Temnoceras

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The carnivorous plant genus Pinguicula (Lentibulariaceae) exhibits remarkable floral diversity associated with pollination, particularly in the largest subgenus Temnoceras, which spans Mexico and Central America. Despite this diversity, the relationships between species and the evolution of key floral traits remain unresolved. Here, we

Spatial Relation of Bumblebees (Hymenoptera-Apidae) with Host-Plant and their Conservation Issues: An Outlook from Urban Ecosystem of Kathmandu Valley, Nepal [PDF]

open access: yes, 2019
Ecology and conservation status of bumblebee species remains poorly understood, especially in rapidly degrading urban ecosystems, which is important considering the role of bumblebees in the pollinations. We collected more than 200 bumblebee (Bombus

Foraging: An ecology model of consumer behaviour? [PDF]

open access: yesMarketing Theory, 2012
Foraging theory is a well established set of models and ideas in ecology, anthropology and behavioural psychology. Two areas of research, the behavioural ecology of consumption and information foraging, have made strides in the application of foraging theories in relation to consumption and related behaviours.

The role of disease in bee foraging ecology [PDF]

open access: yesCurrent Opinion in Insect Science, 2017
Diseases have important but understudied effects on bee foraging ecology. Bees transmit and contract diseases on flowers, but floral traits including plant volatiles and inflorescence architecture may affect transmission. Diseases spill over from managed or invasive pollinators to native wild bee species, and impacts of emerging diseases are of ...

Mechanistic Insights Into Photocatalytic Materials for Toxic Pollutants: Environmental Remediation of Personal Care Products

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Photocatalytic materials have emerged as promising solutions for environmental applications due to their ability to degrade organic pollutants under sunlight or artificial light. In this review, recent progress on the photocatalytic materials used for the degradation of pharmaceutical personal care products (PPCPs) in environmental ...

Ecology: Honey Bee Foraging in Human-Modified Landscapes [PDF]

open access: yesCurrent Biology, 2014
Comprehensive information on the spatial resource use of honey bees is rare, but highly relevant to assess the consequences of habitat loss and fragmentation, agricultural intensification or extensification on colony fitness, pesticide exposure risks and pollination functions.

Intra-dance variation among waggle runs and the design of efficient protocols for honey bee dance decoding [PDF]

open access: yes, 2012
Noise is universal in information transfer. In animal communication, this presents a challenge not only for intended signal receivers, but also to biologists studying the system.
