Yearly fluctuations of flower landscape in a Mediterranean scrubland: Consequences for floral resource availability. [PDF]

open access: yesPLoS ONE, 2018
Species flower production and flowering phenology vary from year to year due to extrinsic factors. Inter-annual variability in flowering patterns may have important consequences for attractiveness to pollinators, and ultimately, plant reproductive output.

Reproductive phenology of Passiflora cincinnata Mast. in the semi-arid region of Bahia State, Brazil, based on herbarium data and IDW interpolation [PDF]

open access: yesHoehnea, 2023
We investigated intensity and seasonality of the reproductive phenology of Passiflora cincinnata Mast. and estimated its flowering and fruiting periods by interpolation using Inverse Distance Weighting, for the first time in phenology, based on herbarium

Development, Survival and Phenology of the Sweetclover Weevil Parasitoid, \u3ci\u3ePygostolus Falcatus\u3c/i\u3e (Hymenoptera: Braconidae) [PDF]

open access: yes, 2018
Biennial sweetclovers were widely used for soil improvement and as for- ages in the first half of the 1900s. The introduction of the sweetclover weevil, Sitona cylindricollis, caused a drastic decline in sweetclover acreage.

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

open access: yes, 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 ...

Impacts of climate change on rice production in Africa and causes of simulated yield changes [PDF]

open access: yes, 2019
This study is the first of its kind to quantify possible effects of climate change on rice production in Africa. We simulated impacts on rice in irrigated systems (dry season and wet season) and rainfed systems (upland and lowland).

Pleiotropy of FRIGIDA enhances the potential for multivariate adaptation. [PDF]

open access: yes, 2013
An evolutionary response to selection requires genetic variation; however, even if it exists, then the genetic details of the variation can constrain adaptation.

Tracing phenology of subarctic plant sover the last century [PDF]

open access: yesPolish Polar Research, 2018
Climate change has been affecting plants over the last century and caused changes in life history features such as the flowering time. Herbarium specimens provide a snapshot of the past environmental conditions during their collection.

Deep Learning and Phenology Enhance Large-Scale Tree Species Classification in Aerial Imagery during a Biosecurity Response

open access: yesRemote Sensing, 2021
The ability of deep convolutional neural networks (deep learning) to learn complex visual characteristics offers a new method to classify tree species using lower-cost data such as regional aerial RGB imagery.

Predators do not spill over from forest fragments to maize fields in a landscape mosaic in central Argentina [PDF]

open access: yes, 2017
South America is undergoing a rapid and large scale conversion of natural habitats to cultivated land. Ecosystem services (ESs) still remain important but their level and sustainability are not known.
