Morphology of Arctic cod (Boreogadus saida) assessed according to habitat preference and age in the Beaufort Sea
<p><span>Arctic cod (<em>Boreogadus</em> <em>saida</em>) represents the most widespread and abundant fish in the Arctic and is a critical trophic link in its ecosystems. Like many species endemic to the region, it has lost essential habitat as the extent and thickness of sea ice </span><span>have </span><span>declined substantially in recent </span><span>decades. Extreme warming induced by climate change continues to deteriorate polar marine environments. Thus, understanding how Arctic cod uses and partitions its habitat/environment is central to its conservation. We assessed Arctic cod functional morphology using traditional (including gill rakers) and geometric morphometrics and explored whether these differed among habitats and age classes using multivariate techniques. While distinct ecotypes have been proposed, these were not detected in our analyses. Rather, results show similar patterns in the external morphology of Arctic cod across habitats and age classes in the Beaufort Sea. However, analysis of gill rakers revealed concurrent habitat- and age-specific changes likely associated with dietary preferences. Findings indicate that although Arctic cod does not specialise in external morphological features in any habitat, important aspects of its internal feeding morphology </span><span>shift </span><span>as it grows, likely underpinning important distributional changes and the species' critical role in transferring energy in Arctic marine ecosystems.</span></p>

Data from: Differential persistence favors habitat preferences that determine the distribution of a reef fish
A central focus of population ecology is understanding what factors explain the distribution and abundance of organisms within their range. This is a key issue in marine systems, where many organisms produce dispersive larvae that develop offshore before returning to settle on benthic habitat. We investigated the distribution of the neon goby, Elacatinus lori, on sponge habitat and evaluated whether variation in the persistence of recently settled individuals (i.e., settlers) among different sponge types can result in habitat preferences and establish their observed distribution. We found that E. lori settlers were more likely to occur on large yellow tube sponges (Aplysina fistularis) than on small yellow sponges or brown tube sponges (Agelas conifera). An experiment seeding settlers onto multiple species and sizes of sponge habitat revealed that settlers persist longer on large yellow sponges than on small yellow sponges or brown sponges. Habitat preference experiments also indicated that settlers prefer large yellow sponges over small yellow sponges or brown sponges. Settlers achieved these preference behaviors using visual, but not chemical, cues. Finally, new settlers arriving from the water column were more likely to occur on large yellow sponges than on small yellow sponges or brown sponges, indicating that the observed habitat preferences existed independent of prior experience. These results support the hypothesis that E. lori have evolved behavioral preferences for sponge habitats that will maximize their post-settlement persistence, and that decisions at settlement will shape the population level pattern of settler distribution on coral reefs.

Distribution, response to human disturbance, habitat preferences, and acoustic communication of tree hyraxes of Mt. Kilimanjaro, Tanzania
<p><span>This data consists data from recordings done in Mt. Kilimanjaro. Hourly calls of tree hyraxes have been calculated between 19.00 until 06:00. Dataset also has variables collected by other research groups.</span></p> <p><span>We combined our data of cue count per hour with data to analyse tree hyrax density with explanatory variables to model occupancy of tree hyraxes in Kilimanjaro. Dataset was combined from several research projects conducted within the Kili-Project (Hemp et al. 2018) (Table 1). Variables included forest type, temperature (Appelhans et al. 2015) precipitation (Appelhans et al. 2016). diameter breast height (DBH), leaf density, max vegetation height, and leaf area index (LAI) (Rutten et al., 2015). We also included land use index (LUI) (Peters et al. 2019) to the dataset, which included four different variables (percentage plant biomass removal, agricultural inputs, modification of the vegetation and percentage of agricultural area in the surroundings). </span></p> <p><span>Abstract</span></p> <p><span>Limited knowledge exists of the distribution, habitat selection, behavior and response to human disturbance of many mammalian species from mountains of Africa. This is especially true for nocturnal mammals. We studied acoustically very active tree hyraxes (<em>Dendrohyrax validus validus</em>) from Mt. Kilimanjaro National Park, Tanzania mainly with bioacoustical methods. To gain understanding of the habitat preferences of tree hyraxes we combined bioacoustical data with botanical and meteorological data collected earlier by <span>KiLi Project</span>. According to GLMM analysis, disturbance caused by logging or forest fires significantly reduced tree hyrax calling activity. In Mt. Kilimanjaro, highest density of tree hyraxes was found from 2750 m a.s.l. It seems that extensive hunting in the past and selective logging below elevation 2500 m caused tree hyraxes to move up the mountain. Calls of tree hyraxes in Mt. Kilimanjaro resemble calls emitted by hyraxes in Taita Hills, Kenya; however, there are clear differences in their calling cultures. In Mt. Kilimanjaro tree hyraxes also sing songs, and their acoustic communication is very active and diverse. In most preferred habitats, groups of tree hyraxes may call 4500–5500 times during one night. Calling seem to have elements of turn taking and individual signatures. Future of tree hyraxes in large, 650 km<sup>2</sup>, Mt. Kilimanjaro National Park seems promising and perhaps in the future tree hyraxes will recolonize the whole park area again.</span></p>
Data for functional diversity and habitat preferences of native grassland plants and ground-dwelling invertebrates in private gardens along an urbanisation gradient
<p>Urbanisation influences biodiversity and ecosystem functions. However, private domestic gardens provide habitats for many species. Challenging conditions in urban gardens may support species possessing certain traits, but exclude other species. Functional diversity is therefore often altered in urban gardens. We surveyed native grassland plants and ground-dwelling invertebrates (snails, slugs, spiders, millipedes, woodlice, ants, rove beetles), and compiled data on urbanisation (distance to city centre, percentage of sealed area) and garden characteristics. We furthermore derived data on traits and habitat preferences for the species recorded in the gardens from the literature and own measurements. The survey comprised 35 domestic gardens along a rural-urban gradient in the city of Basel, Switzerland and its surroundings.</p>
