Modeling the Evolution of Insect Phenology

Bulletin of Mathematical Biology, 2008
Climate change is likely to disrupt the timing of developmental events (phenology) in insect populations in which development time is largely determined by temperature. Shifting phenology puts insects at risk of being exposed to seasonal weather extremes during sensitive life stages and losing synchrony with biotic resources.

Individual movement modeling expands the power of migratory species observations: North Atlantic right whale case study

Limnology and Oceanography: Methods, EarlyView.
Abstract Understanding a population's distribution depends on observing the presence and movement of individuals throughout their range. For highly mobile marine species, these observations typically rely on high effort monitoring programs. Tracking enough individuals to understand trends in movement behavior is not always logistically feasible, and ...

Phyllocephalum keralense (Asteraceae) a new species from southern Western Ghats of Kerala, India

Nordic Journal of Botany, EarlyView.
A new species of Phyllocephalum is described and illustrated from Palakkad district of Kerala, India. The new species shows similarity to P. rangacharii but differs with respect to key floral traits, viz. ovoid shape of the capitula, involucral bracts in 3 series, inflated receptacle and ovoid 6‐ribbed ovary with 5–6 densely barbellate pappus setae ...

Tetrataenium paikadae (Apiaceae), a new species from the Western Ghats, India

Nordic Journal of Botany, EarlyView.
A new species, Tetrataenium paikadae C.Rekha, Manudev & Prasanth (Apiaceae), is described from the State of Kerala, India. The new species is characterised by its hirsute to hispid stems, broadly ovate or rounded leaflets, long petioles with hirsute leaf sheaths, tomentose rays, symmetric flowers, ovate‐lanceolate involucel bracteoles, and mericarp ...

SiriusQuality-BioMa-Phenology-Component

, 2018
<p>This is the BioMa component for phenology in the wheat crop model Sirius-Quality. In this component, the timing of the wheat developmental phases, the phyllochron, the number of leaves on mainstem, the final leaf number and the number of tillers

Phenological response to climatic change depends on spring warming velocity

Communications Earth & Environment
Climatic change is dramatically altering phenology but generalities regarding tempo and mode of response remain limited. Here we present a general model framework incorporating spring temperature, velocity of spring warming, and species’ thermal ...

The Impact of Smoothing Techniques on Vegetation Phenology Extraction: A Case Study of Inner Mongolia Grasslands

Agronomy
The selection of data smoothing methods is one of the key steps in extracting land surface phenology parameters from time-series remote sensing data. However, existing studies often use default parameters for denoising the time-series data, neglecting ...

Reinstatement and generic reassignment of Phyllanthus asteranthos Croizat (Phyllanthaceae) based on living plant observations and specimen analysis

Nordic Journal of Botany, EarlyView.
Phyllanthus asteranthos Croizat has been treated as a synonym of P. pulcher Wall. ex Müll. Arg. (syn. Nymphanthus glaucescens (Miq.) R.W.Bouman) since 1987. Through detailed morphological observations of living plants and critical examinations of type materials and additional specimens, this study revealed that the two taxa are morphologically very ...

Taxonomic identities of Coelogyne roseans, C. chen‐tsii and C. niana (Coelogyninae, Orchidaceae)

Nordic Journal of Botany, EarlyView.
The taxonomic identities of Coelogyne roseans (= Pholidota roseans) and C. niana (= P. niana) have long been misunderstood. Our findings indicate that C. chen‐tsii (= P. longipes) is conspecific with C. niana, consequentially C. chen‐tsii is reduced to a synonym of C. niana. Although C. roseans and C.
