Taxonomy and diversity of Marcgraviaceae, north of the São Francisco river, northeast Brazil

Nordic Journal of Botany, EarlyView.
This study provides a comprehensive assessment of Marcgraviaceae species diversity north of the São Francisco river in northeastern Brazil, analyzing species richness and distribution patterns across 384 000 km² of phytogeographic domains. Through field collections, herbarium studies (both physical and digital), and detailed morphological analyses, we ...

Doryctopambolus nunes & Zaldívar-Riverón (Braconidae), a new Neotropical doryctine wasp genus with propodeal spines [PDF]

, 2012
The new Neotropical doryctine genus Doryctopambolus gen. n. is erected to contain D. pilcomayensis (van Achterberg & Braet, 2004), comb. n., which was previously placed within Pambolus (Pambolinae), as well as three new species, D. clebschi sp.

Comparing the power of phylogenetic, trait and network structure information to predict plant–frugivore interactions

Oikos, EarlyView.
Due to the constraints of limited effort and sampling error, observed species interaction networks are an imperfect representation of the ‘true' underlying community. Link prediction methods allow us to construct a potentially more complete representation of a given empirical network by guiding targeted sampling of predicted links, as well as offer ...

Origins of neotropical leafy Hepaticae [PDF]

, 1990
The neotropical hepatic flora, predominantly constituted by members of the Jungermanniales and Metzgeriales, includes a disproportionate number of genera which are endemic (over 38) and a number which evidently originated here but have shown slight and ...

Structural stability of plant–pollinator interactions despite seasonal abundance of long‐tongued hawkmoths

Oikos, EarlyView.
Seasonal environmental cycles affect plant–pollinator interactions by altering plant phenology. Periods of low resource availability can filter pollinators and reduce the complexity of interaction networks, but the extent to which the functional morphology of pollinators influences such filtering remains unclear.

Análisis retrospectivo de las enfermedades parasitarias del mono ardilla (Saimiri sciureus) en dos condiciones ex situ en el noroccidente de los Andes suramericanos

Revista de Medicina Veterinaria, 2011
El mono ardilla (Cebidae: Saimiri sciureus) es una especie de primate neotropical. La mayor susceptibilidad a la presencia de parásitos en estos primates se puede deber a las condiciones ex situ a las que se encuentran sometidos, en donde se exponen a ...

A amostragem estratificada aprimora a compreensão das redes entre morcegos e frutos na Mata Atlântica meridional

Oikos, EarlyView.
Few studies have sought to understand the vertical patterns of bat–fruit systems, and therefore, it is not possible to evaluate whether interpretations based on data collected from a single stratum adequately represent the interaction patterns of this system. In this context, we evaluated the dissimilarity in the assemblage of frugivorous bats, plants,

Increasing dominance of large lianas in Amazonian forests [PDF]

, 2002
Ecological orthodoxy suggests that old-growth forests should be close to dynamic equilibrium, but this view has been challenged by recent findings that neotropical forests are accumulating carbon and biomass, possibly in response to the increasing ...

Floral resource diversity drives spatiotemporal variation in plant–pollinator network structure

Oikos, EarlyView.
Mechanisms underlying community assembly, including those related to species interactions, vary across space and time. Plant–pollinator networks exemplify these dynamics, where link rewiring and turnover mediate adaptations to environmental changes. Bees rely on diverse floral resources (e.g.

Tertiary Climate Change and the Diversification of the Amazonian Gecko Genus Gonatodes (Sphaerodactylidae, Squamata) [PDF]

, 2008
The genus Gonatodes is a monophyletic group of small-bodied, diurnal geckos distributed across northern South America, Central America, and the Caribbean.
