Biogeography: Are Tropical Species Less Specialised? [PDF]

Current Biology, 2012
Species richness increases from the poles to the tropics, which has led to the view that interactions in tropical species are more specialised. A new study on pollinators and seed dispersers finds that tropical interactions are in fact less specialised.

Antennal and abdominal transcriptomes reveal chemosensory gene families in the coconut hispine beetle, Brontispa longissima

Scientific Reports, 2017
Antennal and abdominal transcriptomes of males and females of the coconut hispine beetle Brontispa longissima were sequenced to identify and compare the expression patterns of genes involved in odorant reception and detection.

RNA Sequencing Reveals Phenylpropanoid Biosynthesis Genes and Transcription Factors for Hevea brasiliensis Reaction Wood Formation

Frontiers in Genetics, 2021
Given the importance of wood in many industrial applications, much research has focused on wood formation, especially lignin biosynthesis. However, the mechanisms governing the regulation of lignin biosynthesis in the rubber tree (Hevea brasiliensis ...

Arboreal twig-nesting ants form dominance hierarchies over nesting resources. [PDF]

, 2019
Interspecific dominance hierarchies have been widely reported across animal systems. High-ranking species are expected to monopolize more resources than low-ranking species via resource monopolization. In some ant species, dominance hierarchies have been

Genetic Variation in Tropical Meloidogyne Species

, 1994
In tropical regions the parthenogenetic Meloidogyne spp. are major crop pests. The presence of populations in West Africa which overcome resistance in cultivars as diverse as tomato cv. ‘Rossol’, sweet potato cv. ‘CDH’ and soya bean cv. ‘Forrest’ has been reported (Prot, 1984; Fargette and Braaksma, 1990). The relationship of these populations to other

MULTIPLICAÇÃO IN VITRO DE Swietenia macrophylla KING (MELIACEAE) A PARTIR DE MATERIAL JUVENIL

Ciência Florestal, 2010
Big-leaf mahogany (Swietenia macrophylla King) is an important species for timber production that is considered the most valuable in the world. For this reason its exploitation is indiscriminate and leads this species to the risk of extinction. Moreover,
