Greater temperature sensitivity of plant phenology at colder sites: implications for convergence across northern latitudes [PDF]

, 2017
Warmer temperatures are accelerating the phenology of organisms around the world. Temperature sensitivity of phenology might be greater in colder, higher latitude sites than in warmer regions, in part because small changes in temperature constitute ...

The ecology of attraction: Fruit traits and frugivore diversity in neotropical Piper

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Fruit traits can benefit plant reproduction by enhancing seed dispersal by mutualistic frugivores (e.g. seed dispersal syndromes), but identifying the role of specific fruit traits in mediating frugivory is challenging because these traits can serve multiple functions ...

A study on phenological traits of Abies pindrow (Royle) Spach. in the different sites of Garhwal Himalayas, India [PDF]

, 2018
Phenology, the timing of various events in a species life cycle, is an important life history trait for both plants and animals. Dharali site situated in the highest altitudinal range i.e.

Seasonal body mass dynamics mediate life‐history trade‐offs in a hibernating mammal

Journal of Animal Ecology, EarlyView.
We tested a suite of ecological hypotheses to explain variation in seasonal body mass dynamics of a fat‐storing mammalian hibernator. We further demonstrated that pre‐hibernation mass gain in ground squirrels mediates an annual allocation trade‐off between current and future reproduction as the squirrels forage and rear young under predation risk ...

High Arctic flowering phenology and plant–pollinator interactions in response to delayed snow melt and simulated warming

Environmental Research Letters, 2016
The projected alterations to climate in the High Arctic are likely to result in changes to the short growing season, particularly with varying predicted effects on winter snowfall, the timing of summer snowmelt and air temperatures.

Trade‐offs across life history stages and social association types shape winter communal roosting in a long‐lived raptor

Journal of Animal Ecology, EarlyView.
Our study demonstrates how life history trade‐offs and pair bonds influence winter roosting in red kites. Analysing long‐term GPS data from 216 individuals, we reveal marked behavioural plasticity in communal roosting: young, non‐breeding males are most likely to join communal roosts, whereas breeding pairs predominantly roost together near their ...

Phenological Gardens Protocol [PDF]

, 2003
The purpose of this resource is to observe the flowering and leaf stages of selected garden plants throughout the year. After a phenological garden is planted, students observe the growth of leaves and blooming of flowers on the plants. These plants were

Record phenological responses to climate change in three sympatric penguin species

Journal of Animal Ecology, EarlyView.
This paper is impressive because we managed to monitor extensively a really difficult place to reach and operate in. We deployed 77 cameras across Antarctica and the Sub Antarctic islands to monitor three different species of penguins. We found that they are the fastest advancing vertebrates with respect to their timing of breeding.

Can arctic migrants adjust their phenology based on temperature encountered during the spring migration? The case of the greater snow goose

Frontiers in Bird Science
The reproductive phenology of many long-distance migrants breeding at high latitudes remains unresponsive or responds only slightly to climate warming.

Spatial overlap and temporal synchrony between guilds of insect hosts and parasitoids

Journal of Animal Ecology, EarlyView.
This study identified a spatial overlap between insect host guild richness and parasitoid richness. Species richness in parasitoid guilds always increased later in the season than richness of their host guilds. These findings suggest that shifts in climate and land‐use may alter the synchrony of insect trophic layers.
