{"title":"On Publication Ethics—Journals, Please Get Rid of Wording Restrictions That Include Citations","authors":"Wolfgang Goymann","doi":"10.1111/eth.13550","DOIUrl":"https://doi.org/10.1111/eth.13550","url":null,"abstract":"&lt;p&gt;“Damn, they didn't cite me!” Do you know this feeling? Honestly, I have experienced such a wave of anger and disappointment quite often when reading papers close to my field. In some cases, I felt so wronged that I sent a friendly email to the authors reminding them of my work. Maybe they just did not know about it? Maybe they did a poor job of searching for the relevant literature? Or they thought my work was not of sufficient quality to be cited? Or is it that I keep choosing the wrong keywords so that no one can find my studies? I am sure, others will have thought the same about some of my papers, that is I did not cite their work even though it was relevant.&lt;/p&gt;&lt;p&gt;There are many reasons why relevant publications are not cited. In the worst case, it can be scientific misconduct, that is authors deliberately fail to cite other people's work when they know it is relevant and should be cited. I am convinced, however, that this is only a minority of cases. In recent decades, the number of scientific studies (and journals) has kind of exploded, making it difficult to keep up with developments even within one's own field. Combined with a poor literature search, this can lead to the omission of relevant work. Further, instead of searching for relevant literature themselves, many people rely on reviews, but this means that the quality of the respective review determines whether readers find the relevant literature to cite. Plus, there may be a good number of other reasons why studies are not cited, but I want to focus on one important cause that is in the responsibility of publishers.&lt;/p&gt;&lt;p&gt;Many journals, especially such with a high impact, have word limits for their articles. In principle, this is fine, as it forces authors to write in a concise and focused manner. However, the word limit often includes the references. In my view, this is plain wrong and should never happen. When the word limit includes references, it is of course much easier for authors to shorten their articles simply by omitting references rather than by reducing their text: eliminating 10 or so references can easily save 150 and more words. In other cases, journals do not include citations in their word limit, but instead they limit the allowed number of references as such. This basically means that the journal forces authors to actively exclude potentially relevant references. In the worst case, such a reference limit is even requested for review articles, whose main purpose should be to provide an overview by including ideally all of the relevant citations.&lt;/p&gt;&lt;p&gt;Sometimes, the authors of articles that did not cite my work responded to my emails. In a few cases, they stated that they were not aware of my work and were grateful that I had brought it to their attention. In most cases, however, they said that they had to focus on the most relevant citations because of word limits or restrictions on the number of citations allowed. And of course, they and I may disagree about wh","PeriodicalId":50494,"journal":{"name":"Ethology","volume":"131 4","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eth.13550","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143595537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some defensive behaviors of grouped animals involve body movements. However, how those behaviors are triggered varies, and how between-individual morphological variation affects them remains unknown. In this project, we explored three drivers of bobbing—an up-and-down body vibration behavior assumed to be a defensive response—with field observations and a lab experiment in one species of the arachnid order Opiliones (<i>Prionostemma</i> sp.2). First, we explored the variation in bobbing duration across groups of a variable number of individuals, as animals could modulate their engagement in this behavior to ensure a successful predator-deterrent behavior. We found that the duration of bobbing increased with group size. Second, we explored the effect of different triggering stimuli that might represent natural scenarios of an approaching predator. We found that a touching stimulus (gentle stick touching) triggered longer bobbing than an airflow stimulus (gentle blow). Third, we explored if the individuals' leg condition (whether they had all eight or fewer legs when found) affects their engagement in this behavior. We found that variations in leg condition did not affect their defensive engagement, as bobbing duration was similar between intact individuals and those missing legs. Together, these data provide novel observational and experimental insights into the drivers of collective behavior in animals. While individual variation in morphological conditions does not affect bobbing in these understudied arachnids, variability in group size and the triggering stimuli impacted their engagement in movement behavioral defenses.</p>","PeriodicalId":50494,"journal":{"name":"Ethology","volume":"131 5","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eth.13551","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143818547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An example is the nesting behaviour of the female European rabbit \u0000 <i>Oryctolagus cuniculus</i>\u0000 and her offspring. After giving birth in a nest of dry grass and fur, mothers return to briefly nurse once a day and deposit faecal pellets there. In domestic rabbits, we examined the temporal pattern of mothers' defecation in the nest, the response of pups to these faeces and the effect of these and nest hay on pups' pre- and postweaning growth and survival. In Experiment 1, we tested primiparous and multiparous mothers given a nest box and hay and allowed access to their pups once a day to nurse. We recorded daily the number of faecal pellets deposited in the nest and the number nibbled by the pups until weaning on postnatal day 30. Mothers defecated in the nest until around postnatal day 12. The pellets and hay then started to be nibbled by the pups, and histological analysis showed that pups ingested plant material. We found no difference in maternal behaviour between primiparous and multiparous females. In Experiment 2, we investigated the growth and survival of pups before and after weaning: (1) with hay and mother's faeces present in the nest; (2) without hay; (3) without mother's faeces; and (4) without hay or mother's faeces. In condition 1, pups transitioned to solid food with little sign of digestive pathology, whereas in conditions 2 and 3, and particularly in condition 4, pups developed diarrhoea and several died. Thus, the presence of nest hay and mother's faeces appear to contribute to pups' transition to solid food. We conclude that rabbits show a well-coordinated pattern of behaviour between mothers and their preweaning offspring, likely relevant to the appropriate management of domestic rabbits.</p>","PeriodicalId":50494,"journal":{"name":"Ethology","volume":"131 5","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eth.13555","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143818548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the majority of these shorebirds hunt on burrowing crabs, the endemic crab plover \u0000 <i>Dromas ardeola</i>\u0000 additionally feeds on swimming crabs with “fast and powerful claws”. Here, we examined the trade-off made by crab plovers between foraging for swimming crabs and burrowing crabs on the intertidal mudflats of Barr Al Hikman in the Sultanate of Oman during four winters (2012–2015). Foraging on burrowing crabs requires waiting for the occupant to emerge, whereas foraging on swimming crabs involves searching and extensive handling. We found that crab plovers strongly preferred swimming crabs. In fact, diet composition was exclusively a function of the densities of swimming crabs, that is, crab plovers stopped waiting for burrowing crabs above threshold densities of swimming crabs even if burrowing crabs were abundant. Using a two-prey functional response model, we could explain diet composition from an energy-maximization perspective, but only if waiting time was added as an identification phase independent of prey densities. This suggests that crab plovers exhibit selective attention and can only wait for a limited number of burrowing crabs at a time. We conclude that the preference for swimming crabs emerges from both the efficient handling of swimming crabs by the crab plover and the long hiding times of the burrowing crabs. Undoubtedly, it is the crab plovers' specialized bill which makes handling of swimming crabs profitable. We speculate that this bill uniquely evolved in the “escalated” environment of the Indo-West Pacific.</p>","PeriodicalId":50494,"journal":{"name":"Ethology","volume":"131 5","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eth.13554","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143818442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prey must consistently assess their surroundings by using multiple information sources to monitor predation risk and respond accordingly. In aquatic environments, chemical signals (i.e., alarm cues, disturbance cues, and predator odors) play a crucial role in informing prey of predation risk. Here, we systematically assess the impact of two non-lethal cues, disturbance cue and predator odor, on four aspects of prey fish behavior using the common blackchin shiner (<i>Miniellus heterodon</i>), a possible surrogate species for the Threatened pugnose shiner (<i>Miniellus anogenus</i>). In experiment 1, we found that conspecific disturbance cue elicited an increase in activity relative to the controls. However, there were no changes in area use, shoaling, or shelter use. In experiment 2, we found that predator odor elicited increased shelter use in blackchin shiner, consistent with an antipredator strategy, but no changes in activity, area use, or shoaling. Our two experiments suggest that disturbance cues and predator odors elicit different behavioral responses in blackchin shiner, perhaps since sources of risk information vary in their urgency and reliability. These results aimed to provide the baseline for future work on pugnose shiner, and demonstrate the value of using non-lethal chemical cues, with standardized methods, to study antipredator behavior in threatened species.</p>","PeriodicalId":50494,"journal":{"name":"Ethology","volume":"131 5","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eth.13553","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143818350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aggression and evasion are key examples of thermally dependent behaviors that can impact fitness. However, we know relatively little about how the thermal plasticity of such behaviors varies among close relatives and impacts competitive outcomes. Woodland salamanders (Genus: <i>Plethodon</i>) from the Appalachian Mountains are distributed across wide thermal gradients in accordance with latitude or elevation. These plethodontid (lungless) salamanders compete for space and develop hybrid zones where territories overlap among species. Plethodontids tend to exhibit increased aggression at warmer temperatures, suggesting that as temperatures rise, behavioral interactions may be altered in ways that impact hybrid zone dynamics. It is thus far unclear, however, how salamander hybrids, which may encroach on their parent populations and drive competitive exclusion, respond behaviorally to warming. Here, we used staged bouts to examine the effects of temperature on aggression and evasion in the \u0000 <i>Plethodon shermani</i>\u0000 and \u0000 <i>Plethodon teyahalee</i>\u0000 hybrid system from the southern Appalachians. The behavior of salamanders from parent populations, particularly <i>\u0000 P. shermani,</i> appears to be more sensitive to thermal changes than that of hybrid individuals. Additionally, evasive behavior was significantly more plastic than aggressive behavior in response to warming. Our results suggest that rising temperatures may increase competition for preferable microhabitats, but the effects on behavior among parental and hybrid salamanders will be asymmetric. Temperature may therefore alter the outcomes of competition, determining which populations can persist under rapid warming.</p>\u0000 </div>","PeriodicalId":50494,"journal":{"name":"Ethology","volume":"131 5","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143818716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
