Gas exchange patterns and water loss rates in the Table Mountain cockroach, Aptera fusca (Blattodea: Blaberidae)
(Company of Biologists, 2013)The importance of metabolic rate and/or spiracle modulation for saving respiratory water is contentious. One major explanation for gas exchange pattern variation in terrestrial insects is to effect a respiratory water ... -
Genetic analysis along an invasion pathway reveals endemic cryptic taxa, but a single species with little population structure in the introduced range
(John Wiley & Sons Ltd, 2016)Aim The invasion pathways of pest arthropods can be traced using genetic tools to develop an understanding of the processes that have shaped successful invasions and to inform both pest management and conservation strategies ... -
Genetic characterization of Taiwan commercial native chickens ascertained by microsatellite markers
(Japan Poultry Science Association, 2013-04-25)Taiwan commercial native chickens have played a vital role in the domestic market due to Taiwanese traditional cooking style and culture. This study investigated the genetic characterization and population structure of 10 ... -
Genetic diversity of Vietnamese domestic chicken populations as decision-making support for conservation strategies
(Stichting International Foundation for Animal Genetics, 2013-02-26)The aims of this study were to assess the genetic diversity of 17 populations of Vietnamese local chickens (VNN) and one Red Jungle Fowl population, together with six chicken populations of Chinese origin (CNO), and to ... -
Genetic rescue persists beyond first-generation outbreeding in small populations of a rare plant
(The Royal Society, 2007)Habitat fragmentation commonly causes genetic problems and reduced fitness when populations become small. Stocking small populations with individuals from other populations may enrich genetic variation and alleviate ... -
Ghosts from the past: even comprehensive sampling of the native range may not be enough to unravel the introduction history of invasive species – the case of Acacia dealbata invasions in South Africa
(Botanical Society of America, 2019)PREMISE OF THE STUDY: Knowledge about the introduction history (source(s), number and size of introduction events) of an invasive species is a crucial prerequisite to understand invasion success and to facilitate effective ... -
A global analysis of molecular markers and phenotypic traits in local chicken breeds in Taiwan
(2012)Molecular and phenotypic data have been combined to characterize the genetic diversity of six local chicken breeds maintained with a long-term conservation programme. Hua-Tung, Hsin-Yi, Ju-Chi and Quemoy originated from ... -
A global database of ant species abundances
(Ecological Society of America, 2017)What forces structure ecological assemblages? A key limitation to general insights about assemblage structure is the availability of data that are collected at a small spatial grain (local assemblages) and a large spatial ... -
A global database of C4 photosynthesis in grasses
(New Phytologist Trust, 2014)C3,C4 or Crassulacean acid metabolism (CAM) photosynthetic pathways represent a fundamental axis of trait variation in plants,with importance at scales from genome to biome. Knowing the distribution of these pathways among ... -
Global invasion of Lantana camara: Has the climatic niche been conserved across continents?
(Public Library of Science, 2014-10-24)Lantana camara, a native plant from tropical America, is considered one of the most harmful invasive species worldwide. Several studies have identified potentially invasible areas under scenarios of global change, on the ... -
Global Invasive Alien Species Indicator Database
(2012-03-07)Database of invasive alien species (including plants, mammals, birds, fish and amphibians) present in 57 countries, with references for impact and spread information. -
GlobalAnts: a new database on the geography of ant traits (Hymenoptera: Formicidae)
(The Royal Entomological Society, 2017)1. In recent years the focus in ecology has shifted from species to a greater emphasis on functional traits. In tandem with this shift, a number of trait databases have been developed covering a range of taxa. Here, ... -
Habitat disturbance selects against both small and large species across varying climates
(Nordic Society Oikos, 2018)Global extinction drivers, including habitat disturbance and climate change, are thought to affect larger species more than smaller species. However, it is unclear if such drivers interact to affect assemblage body size ... -
Harnessing degraded lands for biodiversity conservation
(Elsevier GmbH, 2011)Land degradation affects an estimated 24% of the global land area. While predominantly discussed as an environmental problem, degraded lands have recently been reconsidered as an untapped resource for production industries ... -
High genetic diversity declines towards the geographic range periphery of Adonis vernalis, a Eurasian dry grassland plant
(German Botanical Society and The Royal Botanical Society of the Netherlands, 2015)Genetic diversity is important for species’ fitness and evolutionary processes but our knowledge on how it varies across a species’ distribution range is limited. The abundant centre hypothesis (ACH) predicts that ... -
High metabolic and water-loss rates in caterpillar aggregations: evidence against the resource-conservation hypothesis
(Company of Biologists, 2013)Several hypotheses have been proposed for explaining animal aggregation, including energy or water conservation. However, these physiological hypotheses have not been well investigated. Here, we report the effects of ... -
Historical range contraction, and not taxonomy, explains the contemporary genetic structure of the Australian tree, Acacia dealbata Link
(Springer, 2018)Irrespective of its causes, strong population genetic structure indicates a lack of gene flow. Understanding the processes that underlie such structure, and the spatial patterns it causes, is valuable for conservation ... -
How much evolutionary history in a 10x10m plot?
(2006)We use a fully dated phylogenetic tree of the angiospermfamilies to calculate phylogenetic diversity (PD) in four South African vegetation types with distinct evolutionary histories. Since the branch length values are in ... -
Human activities, propagule pressure and alien plants in the sub-Antarctic: Tests of generalities and evidence in support of management
(Elsevier Ltd., 2013)Despite concerns about the richness of plant invaders on islands, and their likely effects on local systems, impacts of these species seem to be small. However, this may be due to an absence of information on impacts, ... -
Human health risks of metal and metalloids in muscle tissue of Synodontis zambezensis Peters, 1852 from Flag Boshielo Dam, South Africa
(NISC (Pty) Ltd, 2017)Muscle tissue from 63 Synodontis zambezensis collected bimonthly in 2013 at Flag Boshielo Dam were analysed for metals and metalloids in a desktop human health risk assessment. The Hazard Quotient, based on a weekly meal of ...
