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.

Predicting species diversity in tropical forests [PDF]
Proceedings of the National Academy of Sciences, 2000 A fundamental question in ecology is how many species occur within a given area. Despite the complexity and diversity of different ecosystems, there exists a surprisingly simple, approximate answer: the number of species is proportional to the size of the area raised to some exponent. The exponent often turns out to be roughly 1/4.

Inferring species interactions in tropical forests [PDF]
Proceedings of the National Academy of Sciences, 2009 We present 2 distinct and independent approaches to deduce the effective interaction strengths between species and apply it to the 20 most abundant species in the long-term 50-ha plot on Barro Colorado Island, Panama. The first approach employs the principle of maximum entropy, and the second uses a stochastic birth–death model.

DNA barcodes distinguish species of tropical Lepidoptera. [PDF]
Proceedings of the National Academy of Sciences, 2006 Although central to much biological research, the identification of species is often difficult. The use of DNA barcodes, short DNA sequences from a standardized region of the genome, has recently been proposed as a tool to facilitate species identification and discovery. However, the effectiveness of DNA barcoding for identifying specimens

Herbicide Selectivity in Tropical Ornamental Species [PDF]
Planta Daninha, 2016 ABSTRACT This study evaluated the selectivity of herbicides applied post-emergence on ornamental plants of Alpinia purpurata, Strelitzia reginae and Heliconia psittacorum. The study was conducted in two seasons. The experimental design was completely randomized with four replications.

An Overview of the Isoprenoid Emissions From Tropical Plant Species
Frontiers in Plant Science, 2022 Terrestrial vegetation is the largest contributor of isoprenoids (a group of biogenic volatile organic compounds (BVOCs)) to the atmosphere. BVOC emission data comes mostly from temperate regions, and less is known about BVOC emissions from tropical ...

A phenology model for tropical species that flower multiple times each year
Ecological research, 2019 Funding information Smithsonian Tropical Research Institute; Environmental Sciences Program of the Smithsonian Institution Abstract Phenology models developed for temperate and boreal plants predict a single, population-level first flowering date for ...

Scientific Reports, 2020 The magnitude and ecological impact of climate change varies with latitude. Several recent models have shown that tropical ectotherms face the greatest risk from warming because they currently experience temperatures much closer to their physiological ...

BMC Genomics, 2020 Background As air temperatures increase globally, more and more plants are exposed to heat-stress conditions. Although many studies have explored regulation networks in plants with the aim of improving their heat-stress tolerance, only few have revealed ...
