The role of growing degree-days in explaining moth species distributions at broad scales
<p>Growing degree-days (GDD), an estimate of an organism's growing season length, has been shown to be an important predictor of Lepidopteran species' distributions and could be influencing Lepidopteran range shifts to climate change. Yet, one understudied simplification in this literature is that the same thermal threshold is used in the calculations of GDD for all species instead of a species-specific threshold. By characterizing the phenological process influenced by climate, a species-specific estimate of GDD should improve the accuracy of species distribution models (SDMs). To test this hypothesis, we use published lab-estimated thermal thresholds and modeled the current geographic distribution of 30 moth species native to North America. We found that the predictive performance of models based on a species-specific estimate of GDD was indistinguishable from models based on a standard estimate of GDD. This is likely because GDD was not an important predictor of these species' distributions. Our findings suggest that lab-estimated thermal thresholds may not always scale up to be predictive at broad scales and that more work is needed to leverage the data from lab experiments into SDMs to accurately predict species' range shifts in response to climate change.</p>

Species of Acantholichen occurring only in the Neotropics show a high degree of endemism (Dal Forno et al. 2016). Of the seven species now recognized in this genus (Table 2), 71.4% (5) are known only from South America. As with Dictyonema, Acantholichen seem to be specific to substrate type and appears in the Andean small forest occurring on mosses in tree bark inhabiting mostly exposed habitats. Cyphellostereum is also represented by a high number of species restricted to the Neotropics [6 (66.6%)], while one is known only from North America, one from Southeastern United States and Puerto Rico, and another species is known only from Borneo and Fiji (Table 2). It is probably due to their unusual appearance that these lichens are getting confused with free-living cyanobacteria colonies, and that there are still undescribed species in the Neotropics. in Eight new species of lichenized Basidiomycota in the genera Acantholichen, Cyphellostereum and Dictyonema s.str.

Unexpected degrees of male courtship in a highly sexually dimorphic sex-role reversed species: raw data
<p>This repository contains the behavioural data collected from video recordings of 10 mesocosms containing *S. nigra* males and females (which were run in 2020-2021). The goals of the study are to:</p> <p>1. Describe the courtship behaviours of these sexually dimorphic fish<br> 2. Establish whether one sex is more active in courtship than the other<br> 3. Determine factors the influence sex-specific behaviours</p> <p>The data provided here are in two zipped directories: Chase_datasheets/ and BORIS_data/. Both contain data from analysis of videos in BORIS. The BORIS_data/ contains the majority of the courtship behaviours, but the videos were re-analysed to investigate chase behaviours after the courtship behaviours were scored. The chase behaviour data is in Chase_datasheets/.</p>
Replaced feathers, degree of bill corrugation, and bill coloration in 19 Central American hummingbird species
<p>We document molt extent; age-specific molt patterns, plumages, and percent of the bill with corrugations; the presence or absence of delayed plumage maturation and bill color changes in males of some species; and molt timing in the 19 resident hummingbird species of Belize. Molt strategies and rates of bill smoothing were similar to North American species, with all species showing limited to partial preformative molts, replacing only body feathers and some wing coverts and retaining all remiges and rectrices. Extent of bill corrugations reduced to ≤10% of bill length in all species by the time definitive cycle basic plumage is achieved. Males in sexually dichromatic species showed delayed maturation in plumage characteristics and/or bill coloration, and in two dichromatic species, some older females showed male-like plumage. Nine species representing multiple clades showed advanced timing to the second prebasic molt, indicating that this trait may be a proximal response to individuals not breeding during the first molt cycle. Species with advanced second prebasic molts replaced fewer wing coverts during the preformative molt than species with later molt timing.</p>
