Grass functional traits reflect the long history of fire and grazers in the savannas of Texas

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

An algorithm for cross-lingual sense-clustering tested in a MT evaluation setting [PDF]

open access: yes, 2010
Unsupervised sense induction methods offer a solution to the problem of scarcity of semantic resources. These methods automatically extract semantic information from textual data and create resources adapted to specific applications and domains of ...

Does the abiotic environment influence the distribution of flower and fruit colors?

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Color in flowers and fruits carries multiple functions, from attracting animal partners (pollinators, dispersers) to mitigating environmental stress (cold, drought, UV‐B). With research historically focusing on biotic interactions as selective agents, however, it remains unclear whether abiotic stressors impact flower and fruit colors ...

Enneapterygius pallidoserialis, a Junior Synonym of Enneapterygius erythrosoma (Perciformes: Tripterygiidae)

open access: yesSpecies Diversity
Enneapterygius pallidoserialis Fricke, 1997, previously considered a valid species, is regarded as a junior synonym of E. erythrosoma Shen, 1994. Re-examination of type specimens of both nominal species revealed that the meristic and morphometric ...

Distinguishing Antonyms and Synonyms in a Pattern-based Neural Network

open access: yes, 2017
Distinguishing between antonyms and synonyms is a key task to achieve high performance in NLP systems. While they are notoriously difficult to distinguish by distributional co-occurrence models, pattern-based methods have proven effective to ...

Toward a macroevolutionary understanding of live‐leaf flammability in plant species of fire‐prone forests

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The flammability of live leaves in canopies varies considerably among plant species. Identifying macroevolutionary processes that shape variation in leaf flammability contributes to an understanding of the phylogenetic underpinnings of wildfire dynamics.

Peptidic Tryptophan Halogenation by a Promiscuous Flavin‐Dependent Enzyme

open access: yesAngewandte Chemie, EarlyView.
ChlH, a flavin‐dependent tryptophan halogenase, was reconstituted in vitro and capable of modifying a wide array of diverse peptidic substrates. This suggests a potential use in the biocatalytic production of chlorinated peptides. Abstract Amino acids undergo numerous enzymatic modifications.

Taxonomy of Phanaeus revisited: revised keys to and comments on species of the New World dung beetle genus PhanaeusMacLeay, 1819 (Coleoptera: Scarabaeidae: Scarabaeinae: Phanaeini) [PDF]

open access: yes, 2013
The purpose of this paper is to reassess the taxonomy of Phanaeus MacLeay (Coleoptera: Scarabaeidae) to accommodate new taxa and changes in taxonomic opinion since the publication of Edmonds’ 1994 revision of the genus.
