Large and exaggerated sexually selected weapons comprise high proportions of metabolically inexpensive exoskeleton
<p>The cost-minimization hypothesis proposes that positive allometry in sexually selected traits can be explained if the proportional energetic maintenance costs of weapons decrease as traits increase in size. Energetic maintenance costs are the costs of maintaining homeostasis. They are slow, persistent energy sinks that are distinct from ephemeral costs of growth. Because some tissues expend more energy on maintenance than others, energetic maintenance costs can be inferred from proportional tissue composition. For example, soft tissues require more energy for maintenance than exoskeleton, so an arthropod claw that is 50% soft tissue and 50% exoskeleton would have higher energetic maintenance costs than one that is 30% soft tissue and 70% exoskeleton. I tested the cost-minimization hypothesis using proportional tissue composition as a proxy for energetic maintenance costs in snapping shrimp ( Alpheus heterochaelis and Alpheus estuariensis ) and fiddler crabs ( Uca pugilator ). As predicted, larger weapons comprised proportionally less soft tissue mass and more exoskeleton mass than smaller weapons. Furthermore, I extended cost-minimization to explain trait exaggeration: individuals might exaggerate traits by investing more mass in exoskeleton. As predicted, exoskeleton mass proportional to weapon mass increased as exaggeration increased. These results support and extend the cost-minimization hypothesis to explain positive allometry and weapon exaggeration.</p>
Data and codes from: Flight hampers the evolution of weapons in birds
<p>Birds are a remarkable example of how sexual selection can produce diverse ornaments and behaviors. Specialized fighting structures like deer's antlers, in contrast, are mostly absent among birds. Here, we investigated if the birds' costly mode of locomotion — powered flight — helps explain the scarcity of weapons among members of this clade. Our simulations of flight energetics predicted that the cost of bony spurs — a specialized avian weapon — should increase with time spent flying. Bayesian phylogenetic comparative analyses using a global spur dataset corroborated this prediction. First, extant species with flight-efficient wings (which presumably fly more frequently) tend to have fewer or no bony spurs. Second, this association likely arose because flying more leads to more frequent evolutionary loss of spurs. Together, these findings suggest that, much like pneumatic bones, absence of weaponry may be another feature of the avian body plan that allows birds to efficiently explore the aerial habitat.</p>

Defeating the 21st century demon 'Cybercrime' on corporate bodies in Nigeria: is security intelligence a weapon? A quantitative study
<p>This paper unveils the role of security intelligence in facilitating the war against cybercrime in organizations. it introduces the term cybercrime and security intelligence with financial organizations in Nigeria as the focus of the paper. Since the invention of information and communication technology in Nigeria, citizens have become fascinated and engrossed. Unfortunately, it opened the door for people with malicious intent to attack individuals, organizations, and nations. Thus, the paper views the problem of information vulnerability, finds out the level of cybercrime in financial entities, establishes the type of cybercrime, and assesses security intelligence awareness among staff and customers. The paper employed the simple-random sampling technic, using a primary and secondary source of information, analyzing with frequency counts, percentages, and charts for the demographic variables, and the use of chi-square through SPSS data processing. The Discussion of findings states the ubiquity of cybercrime among financial organizations. It reveals that phishing scams, website spoofing, piracy, ransomware, and Hacking are the top cyber-crime types commonly used. Thus, the administration of security intelligence can reduce internal and external threats in an organization. Furthermore, the paper states that security intelligence intervention is independent of the nature of cybercrime across the organization. However, the paper recommends that organizations need to enlighten their staff and customers with measures to safeguard information against cybercrime with the usage of security intelligence techniques or any other proactive measures.</p>

Data from: Sexually selected weapons can wear out, decreasing their effectiveness in combat
<p>Sexual selection has resulted in some of the most elaborate traits seen in animals, many of which are used as weapons. These weapons can be incredibly diverse, even within species. Such morphological variation has largely been attributed to the environment in which individuals are reared and their genetics. However, variation in weapon form could also be the result of a weapon wearing out from usage. This mechanism has received relatively little attention. In this study, we demonstrate that sexually selected weapons can wear out from repeated use, providing experimental evidence that weapon usage can contribute to the diversity of weapon shapes observed within species. In a second experiment, we demonstrate that having a worn-out weapon decreases an individual's fighting ability. This finding illustrates that the shape of a weapon can have an important role in determining contest outcomes. Overall, these results suggest that individuals are limited in the number of times they can effectively use their weapons, which may be one factor (amongst others) influencing how frequently an animal engages in a fight.</p>
A sexually-selected male weapon characterised by strong additive genetic variance and no evidence for sexually antagonistic polyphenic maintenance
<p><span>Sexual selection and sexual antagonism are important drivers of eco-evolutionary processes. The evolution of traits shaped by these processes depends on their genetic architecture, which remains poorly studied. Here, implementing a quantitative genetics approach using diallel crosses of the bulb mite, <em>Rhizoglyphus</em> <em>robini</em>, we investigated the genetic variance that underlies a sexually-selected weapon that is dimorphic among males and female fecundity. Previous studies indicated that a negative genetic correlation between these two traits likely exists. We found male morph showed considerable additive genetic variance, which is unlikely to be explained solely by mutation-selection balance, indicating the likely presence of large-effect loci. However, a significant magnitude of inbreeding depression also indicates that morph expression is likely to be condition-dependent to some degree and that deleterious recessives can simultaneously contribute to morph expression. Female fecundity also showed a high degree of inbreeding depression, but variance in female fecundity was mostly explained by epistatic effects, with very little contribution from additive effects. We found no significant genetic correlation, nor any evidence for dominance reversal, between male morph and female fecundity. The complex genetic architecture underlying male morph and female fecundity in this system has important implications for our understanding of the evolutionary interplay between purifying selection and sexually antagonistic selection.</span></p>
How does the timing of weapon loss influence reproductive traits and trade-offs in the insect Narnia femorata?
<p>A longstanding goal of evolutionary biology is to understand among-individual variation in resource allocation decisions and the timing of these decisions. Recent studies have shown that investment in elaborate and costly weapons can result in trade-offs with investment in testes. In this study, we ask at what point plasticity in resource allocation to these different structures ceases during development, if at all? Furthermore, can individuals tailor their reproductive behavior to accompany structural changes? We experimentally addressed these questions in the insect <em>Narnia femorata</em>, quantifying resource reallocation across development for the first time, using a phenotypic engineering approach. To investigate whether allocation plasticity diminishes throughout ontogeny, we induced weapon loss at a range of different developmental stages and examined subsequent testes mass and reproductive behavior. We found that relative testes mass increased as weapon investment decreased, implying a direct trade-off between testes and weapon investment. However, autotomy post-adulthood ceased to induce larger testes mass. Intriguingly, losing a weapon while young was associated with extended adult mating duration, potentially enabling compensation for reduced fighting ability. Our results highlight the importance of examining the ontogeny of trade-offs between reproductive traits and the flexibility of the relationship between reproductive morphology and behavior.</p>
Data for: Juvenile leg autotomy predicts adult male morph in a New Zealand harvestman with weapon polymorphism
<p><span>Intraspecific weapon polymorphisms that arise via conditional thresholds may be affected by juvenile experiences such as predator encounters, yet this idea has rarely been tested. The New Zealand harvestman <em>Forsteropsalis</em> <em>pureora</em> has three male morphs: majors (alphas and betas) are large-bodied with large chelicerae used in male-male contests, while minors (gammas) are small-bodied with small chelicerae and scramble to find mates. Individuals use leg autotomy to escape predators and there is no regeneration of the missing leg. Here, we tested whether juvenile experience affects adult morph using leg autotomy scars as a proxy of predator encounters. Juvenile </span><span>males that lost at least one leg (with either locomotory or sensory function) had a 45 times higher probability of becoming a minor morph at adulthood than intact juvenile males. </span><span>Leg loss during development may affect foraging, locomotion, and/or physiology, potentially linking a juvenile's predator encounters to their final adult morph and future reproductive tactic.</span></p>

Selection on weapon allometry in the wild
<p class="MsoNormal">Allometry is the scaling relationship between a trait and body size. This relationship can often explain considerable morphological variation within and among species. Nevertheless, much remains unknown about the factors that underlie allometric patterns. For example, when different allometric relationships are observed amongst closely related species, these differences are regularly considered to be products of selection. However, directional selection on allometry (particularly the slope) has rarely been tested and observed in natural populations. Here, we investigate selection on the scaling relationship between weapon size and body size (i.e., weapon allometry) in a wild population of giant mesquite bugs, <em>Pachylis neocalifornicus </em>(previously <em>Thasus neocalifornicus</em>)<em>.</em> Males in this species use their weapons (enlarged femurs) to compete with one another over access to resources and females. We found that large males with relatively large weapons successfully secured access to mates. However, we also found that small males with relatively small weapons could access mates as well. These two patterns together can increase the allometric slope of the sexually selected weapon, suggesting a straightforward process by which the allometric slope can evolve.</p>
Sexually-selected male weapon increases the risk of population extinction under environmental change: An experimental evidence
<p><span>Exaggerated sexually-selected traits, occurring more commonly in males, help individuals to increase reproductive success, but are costly to produce and maintain. These costs on the one hand may improve population fitness by intensifying selection against maladapted males, but on the other hand may increase the risk of extinction under environmental challenge. However, the impact of sexually selected traits on extinction risk have not been investigated experimentally. We used replicate populations of a male-dimorphic mite, <em>Rhizoglyphus robini</em>, to test if prevalence of a sexually-selected weapon affected the risk of extinction under gradual temperature increase (20C per generation). In two independent experiments that utilized either inbred lines or lines mass selected for or against the weapon to establish experimental replicate populations differing in the prevalence of the weapon, we found that populations with high weapon prevalence were more likely to go extinct. Extinctions occurred despite partial suppression of the weapon expression at increased temperature and were not explained by increased male mortality. Our results provide the first, to our knowledge, experimental evidence demonstrating dramatic effect of elaborated sexual traits on the risk of extinction under environmental challenge.</span></p>
