title: Data from: Recombinant DNA modification of gibberellin metabolism alters growth rate and biomass allocation in Populus

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;Overexpression of genes that modify gibberellin (GA) metabolism and signaling have been previously shown to produce trees with improved biomass production but highly disturbed development. To examine if more subtle types of genetic modification of GA could improve growth rate and modify tree architecture, we transformed a model poplar genotype (Populus tremula × P. alba) with eight genes, including two cisgenes (intact copies of native genes), four intragenes (modified copies of native genes), and two transgenes (from sexually incompatible species), and studied their effects under greenhouse and field conditions. In the greenhouse, four out of the eight tested genes produced a significant and often striking improvement of stem volume, and two constructs significantly modified the proportion of root or shoot biomass. Characterization of GA concentrations in the cisgenic population that had an additional copy of a poplar GA20-oxidase gene showed elevated concentrations of 13-hydroxylated GAs compared to wild-type poplars. In the field, we observed growth improvement for three of the six tested constructs, but it was significantly greater for only one of the constructs, a pRGL:GA20-oxidase intragene. The greenhouse and field responses were highly variable, possibly to due to cross-talk among the GA pathway and other stress response pathways, or due to interactions between the cisgenes and intragenes with highly similar endogenes. Our results indicate that extensive field trials, similar to those required for conventional breeding, will be critical to evaluating the value and pleiotropic effects of GA-modifying genes.

title: Data from: Retrogressive moulting in khapra beetle, Trogoderma granarium (Coleoptera: Dermestidae)

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;&lt;p id="132" style="text-align:left;"&gt;&lt;span id="133" class="Dummy"&gt;Insect larvae typically moult to grow, but here we investigate insect larvae that moult to shrink; that is, retrogressive moulting or retrogressive development. We demonstrate this phenomenon in the khapra beetle, &lt;/span&gt;&lt;em&gt;&lt;span id="134" class="fi"&gt;Trogoderma granarium&lt;/span&gt;&lt;/em&gt;&lt;span id="135" class="Dummy"&gt; Everts (Dermestidae), among the world's most invasive pests of stored grains and cereal products, and a quarantine pest of interest for many countries. Larvae survived a 3‐month period of starvation, moulting up to six times and reducing their body mass by about half, on average. When reprovisioned with food, most larvae resumed the normal trajectory of development and pupated within a month. Thus, retrogressive development is a mechanism that may favour species whose resources exhibit feast‐or‐famine dynamics. By enabling survival during periods of privation, retrogressive development contributes to the invasiveness of the khapra beetle by allowing them to persist for long periods in empty storage facilities or empty containers used for international grain shipments.&lt;/span&gt;&lt;/p&gt;

title: Data from: Sexual selection on male vocal fundamental frequency in humans and other anthropoids

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;In many primates, including humans, the vocalizations of males and females differ dramatically, with male vocalizations and vocal anatomy often seeming to exaggerate apparent body size. These traits may be favoured by sexual selection because low-frequency male vocalizations intimidate rivals and/or attract females, but this hypothesis has not been systematically tested across primates, nor is it clear why competitors and potential mates should attend to vocalization frequencies. Here we show across anthropoids that sexual dimorphism in fundamental frequency (F0) increased during evolutionary transitions towards polygyny, and decreased during transitions towards monogamy. Surprisingly, humans exhibit greater F0 sexual dimorphism than any other ape. We also show that low-F0 vocalizations predict perceptions of men’s dominance and attractiveness, and predict hormone profiles (low cortisol and high testosterone) related to immune function. These results suggest that low male F0 signals condition to competitors and mates, and evolved in male anthropoids in response to the intensity of mating competition.

title: Data from: Spatiotemporal patterns of neocortical activity around hippocampal sharp-wave ripples

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;&lt;p&gt;A prevalent model is that sharp-wave ripples (SWR) arise ‘spontaneously’ in CA3 and propagate recent memory traces outward to the neocortex to facilitate memory consolidation there. Using voltage and extracellular glutamate transient recording over widespread regions of mice dorsal neocortex in relation to CA1 multiunit activity (MUA) and SWR, we find that the largest SWR-related modulation occurs in retrosplenial cortex; however, contrary to the unidirectional hypothesis, neocortical activation exhibited a continuum of activation timings relative to SWRs, varying from leading to lagging. Thus, contrary to the model in which SWRs arise ‘spontaneously’ in the hippocampus, neocortical activation often precedes SWRs and may thus constitute a trigger event in which neocortical information seeds associative reactivation of hippocampal ‘indices’. This timing continuum is consistent with a dynamics in which older, more consolidated memories may in fact initiate the hippocampal-neocortical dialog, whereas reactivation of newer memories may be initiated predominantly in the hippocampus.&lt;/p&gt;

title: Data from: Transcontinental latitudinal variation in song performance and complexity in House Wrens (Troglodytes aedon)

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;There is growing interest in latitudinal effects on animal behavior and life-history. One recent focus is on birdsong which is hypothesized to be more elaborated or complex in the north temperate zone compared to the tropics. Current evidence is mixed and based on cross-species comparisons, or single species with restricted distributions. We circumvent these limitations using a transcontinental sample of 358 songs from House Wrens (Troglodytes aedon) at 281 locations spanning more than 100O of latitude (52 O N - 55 O S) across the Americas. We found a significant latitudinal gradient in several basic elements of song performance and complexity between north temperate and tropical populations. Further, we document convergence in song patterns between populations at higher latitudes in the northern and southern hemispheres. Effects were strongest for the number of elements in a song, and the rate of element production, both increasing towards the poles, with similar but weaker effects for other song dimensions (e.g., number of unique elements, trills, and trill rate). We consider possible causes related to variable habitats and morphology, concluding that the shorter breeding seasons at higher latitudes in both hemispheres may favor greater song elaboration to mediate territory competition and mate choice.

title: Data from: When east meets west: population structure of a high- latitude resident species, the boreal chickadee (Poecile hudsonicus)

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;The population genetic structure of northern boreal species has been strongly influenced both by the Quaternary glaciations and the presence of contemporary barriers, such as mountain ranges and rivers. We used a combination of mitochondrial DNA (mtDNA), nuclear microsatellites and spatial distribution modelling to study the population genetic structure of the boreal chickadee (Poecile hudsonicus), a resident passerine, and to investigate whether historical or contemporary barriers have influenced this northern species. MtDNA data showed evidence of eastern and western groups, with secondary admixture occurring in central Canada. This suggests that the boreal chickadee probably persisted in multiple glacial refugia, one in Beringia and at least one in the east. Palaeo-distribution modelling identified suitable habitat in Beringia (Alaska), Atlantic Canada and the southern United States, and correspond to divergence dates of 60–96 kya. Pairwise FST values for both mtDNA and microsatellites were significant for all comparisons involving Newfoundland, though mtDNA data suggest a more recent separation. Furthermore, unlike mtDNA data, nuclear data support population connectivity among the continental populations, possibly due to male-biased dispersal. Although both are significant, the isolation-by-distance signal is much stronger for mtDNA (r2=0.51) than for microsatellites (r2=0.05), supporting the hypothesis of male-biased dispersal. The population structure of the boreal chickadee was influenced by isolation in multiple refugia and contemporary barriers. In addition to geographical distance, physical barriers such as the Strait of Belle Isle and northern mountains in Alaska are restricting gene flow, whereas the Rocky Mountains in the west are a porous barrier.

title: Do habitat and elevation promote hybridization during secondary contact between three genetically distinct groups of warbling vireo (Vireo gilvus)?

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;&lt;p&gt;Following postglacial expansion, secondary contact can occur between genetically distinct lineages. These genetic lineages may be associated with specific habitat or environmental variables and therefore, their distributions in secondary contact could reflect such conditions within these areas. Here we used mtDNA, microsatellite, and morphological data to study three genetically distinct groups of warbling vireo (Vireo gilvus) and investigate the role that elevation and habitat play in their distributions. We studied two main contact zones and within each contact zone, we examined two separate transects. Across the Great Plains contact zone, we found that hybridization between eastern and western groups occurs along a habitat and elevational gradient, whereas hybridization across the Rocky Mountain contact zone was not as closely associated with habitat or elevation. Hybrids in the Great Plains contact zone were more common in transitional areas between deciduous and mixed-wood forests, and at lower elevations (&lt;1000 m). Hybridization patterns were similar along both Great Plains transects indicating that habitat and elevation play a role in hybridization between distinct eastern and western genetic groups. The observed patterns suggest adaptation to different habitats, perhaps originating during isolation in multiple Pleistocene refugia, is facilitating hybridization in areas where habitat types overlap.&lt;/p&gt;

title: Do phylogeny and habitat influence admixture among four North American chickadee (family: Paridae) species

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;&lt;p&gt;Hybridization is an important aspect of speciation, yet questions remain about the ecological and environmental factors that influence hybridization among wild populations. We used microsatellite genotyping data and collected land cover and environmental data for four North American chickadee species: black-capped Poecile atricapillus, mountain P. gambeli, chestnut-backed P. rufescens and boreal P. hudsonicus chickadees. Combining these datasets, we sought to examine whether there is evidence of admixture between four widely distributed North American chickadee species; whether admixture takes place more often between more closely related species pairs or between species pairs with more similar ecological preferences; and whether certain habitat types have higher rates of admixture than others. We detected admixture for five of the six species pairs analyzed (chestnut-backed–mountain chickadee pair showed no evidence of admixture), and found rates of admixture varied geographically, and within taxa pairs. Admixture was higher among less closely related species than more closely related species, although habitat similarity was not a significant predictor. Finally, rates of admixture were higher in urban parkland habitats than deciduous, mixed or coniferous forest habitats. Our work indicates admixture occurs frequently among North American parids, and habitat and environmental variation may play an important role in the frequency and geographic distribution of hybridization.&lt;/p&gt;
description: &lt;b&gt;Methods&lt;/b&gt;&lt;br /&gt;&lt;p&gt;We collected blood samples from 1428 chickadees (representing four common North American species) from 19 geographic data. Individuals were genotyped at five microsatellite loci. We ran species pairs through STRUCTURE at each location to identify individuals with mixed ancestry. We examined the rate of admixture among species pairs and determined whether admixture occurs more frequently between more closely related species pairs (i.e. between species within the black-headed clade or brown-headed clade) or between species pairs with more similar ecological preferences? We also correlate admixture with environment and elevation data to identify habitat and environmental characteristics that may influence admixture among parids. Habitat and environmental data were obtained from the WorldClim dataset for the environmental analyses, and we used COI data to examine and characterize the phylogenetic relationship among the four chickadee species.&lt;/p&gt;

title: Estimating on the fly: the approximate number system in rufous hummingbirds (Selasphorus rufus)

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;&lt;p&gt;&lt;p&gt;When presented with resources that differ in quantity, many animals use a numerosity system to discriminate between them. One taxonomically widespread system is the approximate number system. This is a numerosity system that allows the rapid evaluation of the number of objects in a group and which is regulated by Weber’s Law. Here we investigated whether wild, free-living rufous hummingbirds (Selasphorus rufus) possess an approximate number system. The hummingbirds were presented with two experiments. In the first we investigated whether hummingbirds spontaneously chose an array containing more flowers than an alternate array. In the second we asked whether the hummingbirds could learn to use numerosity as a cue to which of two arrays contained the better reward. The birds did not spontaneously prefer an array containing more flowers. After minimal training, however, they learned to choose the more numerous array and could differentiate between arrays of five and seven flowers. These data support the presence of an approximate number system in the rufous hummingbird. It seems plausible that having such a system would enable much more efficient foraging in this species.&lt;/p&gt;&lt;/p&gt;
description: &lt;b&gt;Methods&lt;/b&gt;&lt;br /&gt;&lt;p style="margin-bottom:11px;"&gt;We trained marked, wild rufous hummingbirds to feed from artificial flowers. In the first experiment we presented birds with two arrays of artificial flowers, one more numerous than the other (e.g., 7 flowers vs 1 flower). We presented birds with eleven different combination of arrays: 1vs2, 1vs3, 1vs4, 1vs5, 1vs6, 1vs7, 2vs7, 3vs7, 4vs7, 5vs, 6vs7and recorded which array the bird visited first. During the second experiment, the array with a smaller number of flowers had a lower quality reward (5% sucrose solution) than the array with more flowers (25% sucrose solution). After birds were presented with a single numerous array (7 flowers) that was highly reward and then with a single array (1 flower) that was rewarded poorly, the birds were presented with two arrays simultaneously for the eleven different array combinations. We recorded how many times it took birds to visit first the more numerous array three times in a row. The order of presentation of the different tests was alternated and counterbalanced on both experiments. &lt;/p&gt;
