### Spatial predictors of genomic and phenotypic variation differ in a lowland Middle American bird (Icterus gularis)

Lucas Rocha Moreira, Blanca E. Hernandez-Baños & Brian T. Smith
Spatial patterns of intraspecific variation are shaped by factors such as geographic distance among populations, historical changes in gene flow and interactions with local environments. Although these factors are not mutually exclusive and operate on both genomic and phenotypic variation, it is unclear how they affect these two axes of variation. We address this question by exploring the predictors of genomic and phenotypic divergence in Icterus gularis, a broadly distributed Middle American bird that exhibits...

### Influence of a magnetic narrow region on the propagation of Type II spicules into the solar corona

José Juan González, Elton E. Díaz-Figueroa & Gonzalo Ares De Parga
In this paper, we study the possible influence of a magnetic narrow region on the propagation of jets with some characteristics of Type II spicules into the solar corona using two approximations: thermo-mechanical (TM) and magnetohydrodynamic (MHD). We motivate the idea of this paper by considering that some advanced 2.5D numerical simulations of radiation MHD of the formation of Type II spicules show the narrowing of the magnetic field lines in the loops where the...

### Idiosyncratic responses to drivers of genetic differentiation in the complex landscapes of Isthmian Central America

Isthmian Central America (ICA) is one of the most biodiverse regions in the world, hosting an exceptionally high number of species per unit area. ICA was formed < 25 million years ago and, consequently, its biotic assemblage is relatively young and derived from both colonization and in situ diversification. Despite intensive taxonomic work on the local fauna, the potential forces driving genetic divergences and ultimately speciation in ICA remain poorly studied. Here, we used a...

### The importance of the Mexican taxa of Asteraceae on the family phylogeny

Patricia Rivera
Asteraceae is the largest plant family in México with about 417 genera and 3,113 species, more than 60% of them endemic. Phylogenetic relationships at subfamily and tribal levels have been previously resolved employing both nuclear and plastid molecular markers. However, Asteraceae species native to Mexico have been underrepresented in such phylogenies. To tackle this issue, the taxon sampling of this study included 90 Asteraceae species native to México, four species from the Caribbean, 119 previously...

### Duet codes do not enhance neighbour recognition in two closely related species of neotropical wrens

Esmeralda Quiros-Guerrero & Esmeralda Quiros-Guerrero
Numerous studies have shown that territorial animals exhibit less aggression in response to neighbours than to strangers, a phenomenon known as dear enemy effect. The influence of acoustic features, such as song type sharing and repertoire sizes, in neighbour recognition has been widely documented in male songbirds. However, few studies have focused on duetting species, and particularly on those where pairs have pair-specific duet codes (consistent associations of their individual phrase types). Given that each...

### Allopatric instead of parapatric divergence in an ectomycorrhizal fungus (Laccaria trichodermophora) in tropical sky-islands

Christian Quintero-Corrales, Rodolfo Ángeles-Argáiz, Juan Pablo Jaramillo-Correa, Daniel Piñero, Roberto Garibay-Orijel & Alicia Mastretta-Yanes
In tropical sky-islands, cold-affinity populations tend to become isolated at highlands during the interglacial periods, and to expand into the lowlands where they become more connected during the glacial periods. Although this has been widely studied in trees, it is poorly understood how fungal symbionts can differentiate among mountains (allopatrically), or within a single mountain (parapatrically) due to climate fluctuations. Here, we conducted population genomic analyses on the ectomycorrhizal fungus Laccaria trichodermophora in three tropical...

### Grad-Shafranov equation: MHD simulation of the new solution obtained from the Fadeev and Naval models

Arian Ojeda Gonzalez, Leandro Nunes Dos Santos, José Juan González-Avilés, Victor De La Luz & Pablo Rubén Muñoz-Gutberlet
This article aims to obtain a new analytical solution of a specific form of the Grad-Shafranov (GS) equation using Walker's formula. The new solution has magnetic field lines with X-type neutral points, magnetic islands and singular points. The singular points are located on the x-axis. The X-points and the center of the magnetic islands do not appear on the x-axis an island appears at $z>0$ and the other two at $z<0$. The aforementioned property allows...

### Atmospheric and soil drought risks combined shape community assembly of trees in a Tropical Dry Forest

Moises Méndez-Toribio, Guillermo Ibarra-Manríquez, Horacio Paz & Edwin Lebrija-Trejos
1. Predicting plant community assembly is challenging in part because the influence of environmental conditions via plant functional strategies and the relevance of mechanisms of community assembly change across habitats and these changes remain poorly studied. 2. To assess how environmental conditions drive species sorting in a tropical dry forest, we used the combined RLQ and Fourth-Corner methods to analyze changes in tree species assemblages among sites with distinct atmospheric and soil drought risks. We...

### Using niche centrality within the scope of the nearly neutral theory of evolution to predict genetic diversity in a tropical conifer species-pair

Jorge Cruz Nicolás, Gustavo Ibrahim Gilés Pérez, Andrés Lira Noriega, Norberto Martínez-Méndez, Erika Aguirre-Planter, Luis E. Eguiarte & Juan Pablo Jaramillo Correa
Aim: Estimating genetic diversity is key for understanging biogeographic and evolutionary processes. However, gathering genetic information is not feasible for all taxa or populations, particularly in the tropical regions. Identifying proxies for inferring such values has thus become essential. Here, we built on the niche centrality hypothesis (NCH; or central-abundance hypothesis) and the nearly neutral theory of evolution (NNT) to identify some of such proxies using a montane tropical conifer species-pair as model. The NCH...
