Fungal endophytes limit pathogen damage in a tropical tree
TLDR
It is shown that inoculation of endophyte-free leaves with endophytes isolated frequently from naturally infected, asymptomatic hosts significantly decreases both leaf necrosis and leaf mortality when T. cacao seedlings are challenged with a major pathogen.
Pervasive density-dependent recruitment enhances seedling diversity in a tropical forest
TLDR
Observations in a lowland, moist forest in the Republic of Panamá found that negative density-dependent recruitment contributes significantly to the increase in diversity from seeds to seedling recruits.
Negative plant–soil feedback predicts tree-species relative abundance in a tropical forest
TLDR
It is found that tree species that showed stronger negative feedback were less common as adults in the forest community, indicating that susceptibility to soil biota may determine species relative abundance in these tropical forests.
Sex Ratio Adjustment in Fig Wasps
TLDR
The results indicate that female fig wasps adjust the sex ratio of their offspring in response to both the intensity of proximate local mate competition and the level of inbreeding in the population.
Cryptic species of fig-pollinating wasps: Implications for the evolution of the fig–wasp mutualism, sex allocation, and precision of adaptation
TLDR
Genetic data demonstrates the coexistence of previously undetected cryptic fig wasp species in at least half of the host fig species surveyed, undermining the prevalent notion of strict one-to-one specificity between cospeciating figs and their pollinators and strengthening support for sex allocation theory and the precision of adaptation.
Colletotrichum gloeosporioides s.l. associated with Theobroma cacao and other plants in Panamá: multilocus phylogenies distinguish host-associated pathogens from asymptomatic endophytes
TLDR
Two new species are formally described, C. tropicale and C. ignotum, that are frequent asymptomatic associates of cacao and other Neotropical plant species, and epitypify C. theobromicola, which is associated with foliar and fruit anthracnose lesions of cacoe and other plant hosts.
Critical review of host specificity and its coevolutionary implications in the fig/fig-wasp mutualism
TLDR
The idea that codivergence between figs and their pollinators has been dominated by strict-sense cospeciation is critically examined and phylogenetic and population genetic data are presented that suggest that a more accurate model for diversification in this mutualism is that of groups of genetically well defined wasp species coevolving with genetically less well defined groups of figs.
The breeding structure of a tropical keystone plant resource
TLDR
Paternity analysis techniques are used to reconstruct the genotypes of pollen donor trees and to estimate pollen dispersal distances and breeding population size parameters for Panamanian populations of seven species of monoecious strangler figs, a particularly widespread and influential group of keystone producers.
Phylogenetic relationships, historical biogeography and character evolution of fig-pollinating wasps
TLDR
The fig–wasp mutualism exhibits extraordinarily long–term evolutionary stability despite clearly identifiable conflicts of interest between the interactors, which is reflected by the very distinct variations found on the basic mutualistic theme.
Evolutionary Ecology of Figs and Their Associates: Recent Progress and Outstanding Puzzles
TLDR
This work addresses several key issues in evolutionary ecology, including evolution of breeding systems (shifts between monoecy and dioecy), factors that promote the stability of mutualisms, precision of adaptation, and trajectories of community assembly and coevolution in systems with multiple interacting partners.
