Seasonal niche tracking of climate emerges at the population level in a migratory bird

Guillermo Fandos, Shay Rotics, Nir Sapir, Wolfgang Fiedler, Michael Kaatz, Martin Wikelski, Ran Nathan & Damaris Zurell
Seasonal animal migration is a widespread phenomenon. At the species level, it has been shown that many migratory animal species track similar climatic conditions throughout the year. However, it remains unclear whether such niche tracking pattern is a direct consequence of individual behaviour or emerges at the population or species level through behavioural variability. Here, we estimated seasonal niche overlap and seasonal niche tracking at the individual and population level of Central European White Storks...

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...

Data from: Quorum-sensing signaling by chironomid egg masses’ microbiota affects haemagglutinin/protease (HAP) production by Vibrio cholerae

Rotem Sela, Brian Hammer & Malka Halpern
Vibrio cholerae, the causative agent of cholera, is commonly isolated, along with other bacterial species, from chironomid insects (Diptera: Chironomide). Nevertheless, its prevalence in the chironomid egg masses’ microbiota is less than 0.5%. V. cholerae secretes haemagglutinin/protease (HAP) that degrades the gelatinous matrix of chironomid egg masses and prevents hatching. Quorum sensing (QS) activates HAP production in response to accumulation of bacterial autoinducers (AIs). Our aim was to define the impact of chironomid microbiota on...

The evolutionary advantage of fitness-dependent recombination in diploids: a deterministic mutation–selection–balance model

Sviatoslav Rybnikov, Zeev Frenkel & Abraham B. Korol
Recombination’s omnipresence in nature is one of the most intriguing problems in evolutionary biology. The question of why recombination exhibits certain general features is no less interesting than that of why it exists at all. One such feature is recombination’s fitness dependence (FD). The so far developed population-genetics models have focused on the evolution of FD recombination mainly in haploids, although the empirical evidence for this phenomenon comes mostly from diploids. Using numerical analysis of...

Data on universities offering undergraduate degrees that train students for soil science careers at universities in the USA and its territories

Several soil science education studies over the last 15 years have focused on the number of students enrolled in soil science programs. However, no studies have quantitatively addressed the number of undergraduate soil science preparatory programs that exist in the United States, which means we do not have solid data concerning whether overall program numbers are declining, rising, or holding steady. This also means we do not have complete data on the same trends for...

Limited divergent adaptation despite a substantial environmental cline in wild pea

Timo Hellwig, Shahal Abbo, Amir Sherman, Clarice Coyne, Yehoshua Saranga, Doreen Main, Ping Zheng, Simcha Lev-Yadun & Ron Ophir
Isolation by environment (IBE) is a wide spread phenomenon in nature. It is commonly expected that the degree of differences among environments is proportional to the level of divergence between populations in these environments. Consequentially, it is assumed that species’ genetic diversity displays pattern of IBE in the presence of a strong environmental cline if geneflow does not mitigate isolation. We tested this common assumption by analyzing the genetic diversity and demographic history of Pisum...
