Honey Ants (Genus Myrmecocystus) Macroecology: Effect of Spatial Patterns on the Relationship between Worker Body Size and Geographic Range Size
Macroecology evaluates the partitioning of physical space and resources among organisms through correlation among ecological variables, such as geographical range size and shape, body size, and population density, measured ...
Effects of detectability on estimates of geographic range size in bignonieae
(BLACKWELL PUBLISHING, 2008)
Extinction risk has not been evaluated for 96% of all described plant species. Given that the Global Strategy for Plant Conservation proposes preliminary conservation assessments of all described plant species by 2010, ...
An event model for phylogenetic biogeography using explicitly geographical ranges
(Wiley Blackwell Publishing, Inc, 2017-10)
Aim: To develop and implement a method for phylogenetic biogeography that is both event based and geographically explicit, that is, that uses the geographical ranges observed in the terminals instead of ‘predefined areas.’. ...
A revised geographical range for Liolaemus elongatus Koslowsky, 1896 (Squamata: Liolaemini) in Argentina: review of reported and new-data based distribution with new localities
(Firenze University Press, 2013-10)
Estimating the effective geographical ranges of species is central to species-oriented conservation and management. In this paper, we review the geographical distribution of Liolaemus elongatus Koslowsky, 1896 with three ...
Geographical distribution of Eupatorieae (Asteraceae) in South-eastern and South Brazilian Mountain Ranges
(Kluwer Academic PublDordrechtHolanda, 2004)
Understanding bias in geographic range size estimates
Aim Estimates of geographic range size derived from natural history museum specimens are probably biased for many species. We aim to determine how bias in these estimates relates to range size. Location We conducted computer ...
Body size and host range co-determine the altitudinal distribution of Neotropical tephritid flies
(Blackwell PublishingOxfordInglaterra, 2007)
Consistency in fruit preferences across the geographical range of the frugivorous bats Artibeus, Carollia and Sturnira (Chiroptera)
(Fundacao Zoobotanica Rio Grande Sul, Museu Ciencias Naturais, 2016-01-01)
The frugivorous phyllostomid bat genera Artibeus, Carollia and Sturnira are important seed dispersers in the Neotropics, and exhibit supposed preferences for fruits of the genus Ficus, Piper and Solanum, respectively. We ...
Patterns of phenotypic selection for oil and nectar in Monttea aphylla (Plantaginaceae) in a geographic mosaic of interactions with pollinators
(Elsevier Gmbh, 2017-07)
Oil-flower species are highly specialized attracting a narrow group of oil-collecting bees in contrast to nectar-flower species visited by a wide diversity of pollinators. The vast majority of the oil species lack nectar ...
Scat detection dogs, DNA and species distribution modelling reveal a diminutive geographical range for the Vulnerable small red brocket deer Mazama bororo
(Cambridge Univ Press, 2017-10-01)
The small red brocket deer Mazama bororo is endemic to the Brazilian Atlantic Forest, a biome that has been greatly fragmented and altered by human activities. This elusive species is morphologically similar to the red ...
