Data from: Human judgment vs. quantitative models for the management of ecological resources
Despite major advances in quantitative approaches to natural resource management, there has been resistance to using these tools in the actual practice of managing ecological populations. Given a managed system and a set of assumptions, translated into a model, optimization methods can be used to solve for the most cost-effective management actions. However, when the underlying assumptions are not met, such methods can potentially lead to decisions that harm the environment and economy. Managers who develop decisions based on past experience and judgment, without the aid of mathematical models, can potentially learn about the system and develop flexible management strategies. However, these strategies are often based on subjective criteria and equally invalid and often unstated assumptions. Given the drawbacks of both methods, it is unclear whether simple quantitative models improve environmental decision making over expert opinion. In this study, we explore how well students, using their experience and judgment, manage simulated fishery populations in an online computer game and compare their management outcomes to the performance of model-based decisions. We consider harvest decisions generated using four different quantitative models: (1) the model used to produce the simulated population dynamics observed in the game, with the values of all parameters known (as a control), (2) the same model, but with unknown parameter values that must be estimated during the game from observed data, (3) models that are structurally different from those used to simulate the population dynamics, and (4) a model that ignores age structure. Humans on average performed much worse than the models in cases 1–3, but in a small minority of scenarios, models produced worse outcomes than those resulting from students making decisions based on experience and judgment. When the models ignored age structure, they generated poorly performing management decisions, but still outperformed students using experience and judgment 66% of the time.

Allochthonous resources are less important for faunal communities on highly productive, small tropical islands
<p><span>Ecosystems are interconnected by energy fluxes that provide resources for the inhabiting organisms along the transition zone. Especially where in-situ production is low, ecosystems can become highly dependent on external resources. The dependency on external input becomes less pronounced in systems with elevated in-situ production, where only consumer species close to the site of external input remain subsidized, whereas species distant to the input site rely on the in-situ production of the ecosystem. It is largely unclear though if this pattern is consistent over different consumer species and trophic levels in one ecosystem, and whether consumer species that occur both proximate to and at a distance from the input site differ in their dependency on external resource inputs between sites. Using stable isotope analysis, we investigated the dependency on external marine input for common ground-associated consumer taxa on small tropical islands with high in-situ production. We show that marine input is only relevant for strict beach-dwelling taxa, while the terrestrial vegetation is the main carbon source for inland-dwelling taxa. Consumer species that occurred both close (beach) and distant (inland) to the site of marine input showed similar proportions of marine input in their diets. This supports earlier findings that the relevance of external resources becomes limited to species close to the input site in systems with sufficient in-situ production. However, it also indicates that the relevance of external input is also species-dependent, as consumers occurring close and distant to the input site depended equally strong or weak on marine input.</span></p>

Body size and digestive system shape resource selection by ungulates: a cross-taxa test of the Forage Maturation Hypothesis
<p>The Forage Maturation Hypothesis (FMH) states that energy intake for ungulates is maximized when forage biomass is at intermediate levels. Nevertheless, metabolic allometry and different digestive systems suggest that resource selection should vary across ungulate species. By combining GPS relocations with remotely-sensed data on forage characteristics and surface water, we quantified the effect of body size and digestive system in determining movements of 30 populations of hindgut fermenters (equids) and ruminants across biomes. Selection for intermediate forage biomass was negatively related to body size, regardless of the digestive system. Selection for proximity to surface water was stronger for equids relative to ruminants, regardless of body size. To be more generalizable, we suggest that the FMH explicitly incorporate contingencies in body size and digestive system, with small-bodied ruminants selecting more strongly for potential energy intake, and hindgut fermenters selecting more strongly for surface water.</p>

Temporal and scalar variations affect resource use of northern bobwhite broods
<p>Disparate resource use originating from phenology of biotic resources, abiotic conditions, and life cycles of exploiting organisms underscores the importance of research across time and space to guide locally relevant management practices. Our goal was to evaluate resource use of northern bobwhite (<i>Colinus virginianus; </i>bobwhite) at two spatial scales and across three age classes, from hatching through a period of the post-juvenile molt. Our study was conducted at Tall Timbers Research Station, Tallahassee, FL, USA– situated in a pyric landscape subjected to biennial prescribed fire. We predicted prescribed fire, disking, and supplemental feeding would dictate resource use, but effects would depend on time since fire, brood age, and time of day. We predicted vegetation and temperature would govern roost use by broods, but these effects would also depend on age. We radio-tracked 62 broods 21–35 times / week during May – October 2018 and 2019. Broods were less likely to use areas with large proportions of hardwood drains but favored sites with greater proportions of burned uplands, regardless of the time of day. Broods were less likely to use areas at greater distances from supplemental feed; this relationship had no interaction with age. The effect of supplemental feed was stronger later in the nesting season (> July 15). Broods were more likely to use areas with greater proportions of fallow fields during the day than for roosting. Broods used roosts with more woody cover and visual obscurity than at available sites. Roosts consisted of less grass and bare ground. However, these effects interacted with age; broods used sparser cover at older ages. Neonate broods were more likely to use cooler roosts with greater thermal stability, but this effect was reversed for juveniles. Broods may alter resource use with changes in vulnerabilities to threats such as thermal risks and predation.</p>
Intraspecific competition and temperature drive habitat-based resource polymorphism in brook charr
<p><span>Intra- and interspecific competition, two density-dependent processes, are the two main driving forces suggested to promote habitat-based resource polymorphism, but very few studies have provided empirical support for this hypothesis. Furthermore, </span><span>external drivers like temperature, an important environmental constraint in ectotherms, are often omitted when studying density-dependent habitat selection. Specifically, ambient temperature may have important effects on habitat-based resource polymorphism in ectotherms. Using mixed-effects modelling and isodar analyses, we quantified the effects of water temperature as well as intra- and interspecific competition on abundance and density-dependent habitat selection of brook charr (<em>Salvelinus</em> <em>fontinalis</em>) between littoral and pelagic habitats in 27 Canadian Shield lakes. We found that interspecific competition with white sucker (<em>Catostomus</em> <em>commersonii</em>) reduced brook charr abundances in both habitats but did not affect their </span><span>density-dependent habitat selection. </span><span>In contrast, the isodar analysis </span><span>showed density-dependent habitat selection, confirming that intraspecific competition is a driver of brook charr habitat use in this system. </span><span>Furthermore, brook charr preferred the littoral habitat at water temperatures below 20.8°C, but preferred the pelagic habitat above this threshold and no longer used the littoral habitat when its temperature was above ~22.2°C. By incorporating an external driver in the density-dependent habitat selection model, we show how the littoral temperature can shape brook charr distribution patterns between the littoral and pelagic habitats by acting as a thermal barrier and thus limiting the willingness of fish to use resources in the littoral habitat. </span><span>This result suggests that global warming could constrain the diversifying effect of intraspecific competition</span><span> and prevent resource polymorphism, a phenomenon that promotes adaptive radiation and speciation</span><span>.</span></p>
Rapid evolution of ecological sexual dimorphism driven by resource competition
<p>Sex differences in ecologically-important traits are common in animals and plants, and prompted Darwin to first propose an ecological cause of sexual dimorphism. Despite theoretical plausibility and Darwin's original notion, a role for ecological resource competition in the evolution of sexual dimorphism has never been directly demonstrated and remains controversial. I used experimental evolution in <em>Drosophila melanogaster</em> to test the hypothesis that resource competition can drive the evolution of sex differences in diet. Following just three generations of adaptation, offspring from flies evolved in low-resource, high-competition environments show elevated sexual dimorphism in diet preference compared to both the ancestor and populations evolved on high resource availability. This increased sexual dimorphism was the result of divergence in male sucrose intake and female yeast intake consistent with the differential nutritional requirements of the sexes. These results provide the first real-time direct evidence for evolution of sexual dimorphism driven by resource competition.</p>

Conformity of E-Learning for Teaching and Learning in Ethiopian Higher Education: Analysis on User-Friendliness of E-Resources
<p>The study investigated the practicability of e-learning for teaching and learning in Ethiopian higher education in terms of availability, clarity, accessibility in terms of accommodation and economy. The research looked into the roles of e-provisions based on the country’s Information and Communication Technology (ICT) in education policy guidelines as benchmark. Descriptive survey research design was used in the research since the study focused on indicating status than in-depth institution-based analysis of technology-use in education. Two higher institutions were selected for their relative proximity and viability for data collection. Data for the research were collected from 150 students, 4 technical support renderers and 30 teachers. Instruments of data collection were binary mode questionnaires and semi-structured interviews. Findings indicated shortage in a purpose-orientation, weak cross-institutional interchange and low mainstreaming of e-resources for course-provision. Though initiatives were high to use e-resources across lessons, shortage in internet access and prevailing digital divides were common barriers. Selective use of e-learning was witnessed on the part of technical support providers. multiplier effects in sharing experiences were not practiced among the teachers. Purpose-conformity was met on highly individualized bases. inter-institutional experiential exchange was insufficient though there was high emphasis on supporting selected instructional strings.</p>

<p>VCF files mapped to <em>Panubis1.0</em> with 881 olive (<em>Papio anubis</em>) and yellow (<em>Papio cynocephalus</em>) baboons from the Southwest National Primate Research Center. VCF files were generated in two separate pipelines, first using Beagle 4.1 and Beagle 5.4 and additionally SHAPEIT5/IMPUTE5 to test if a pedigree-aware software reduced the number of evident phase switch errors. VCFs here have been phased and imputed in their respective pipelines, filtered for imputation accuracy with markers with less than 0.7 confidence removed using BCFTools, and then phase switch corrected using Tractor. Genomic resources (AIMs and Fixed markers) are based off of <em>Panubis1.0 </em>coordinates. Local ancestry estimation completed by RFMix and then phase-switch-corrected using Tractor. </p>
