Who has access to online library databases?
Due to licensing restrictions, off-campus access to databases is generally reserved only for current LSU faculty, staff, and students. On-campus access should be available to anyone connected to the LSU Wireless network. Because public patrons do not have access to LSU Wi-Fi, LSU Library houses a few public access computers in room 241. Non-affiliates and public patrons who are able to visit in person will have full access to databases using these computers. We also have a list of open access databases that should be accessible to everyone from anywhere (see below). The online library catalog is also open to everyone.

How can I renew my books?
There are three different ways you can renew your LSU Library books:
- In-person: Bring your items to the checkout desk in room 241 of LSU Library. Be sure to bring your TigerCard or public patron ID.
- Online: Log into your online library account (link below) and select the "Checkouts" tab.
- Self-checkout: Renew your items using the self-checkout station in room 141 of LSU Library. Be sure to bring your TigerCard or public patron ID. Please contact the Circulation department with additional questions or concerns: libcirc@lsu.edu (mailto:libcirc@lsu.edu) . LSU Libraries | Library Catalog Account Answered by: Access Services Staff
Why does my library account say that I am blocked, that I am barred, or that my status is expired?
Users can encounter several different types of status messages. Patrons with questions about their account status can visit the checkout desk in room 241 of LSU Library and ask to speak to a staff member. Alternatively, patrons can reach out to us via e-mail at libcirc@lsu.edu (mailto:libcirc@lsu.edu) . When contacting us via e-mail, LSU students, staff, and faculty should message us from their LSU e-mail address; public patrons should message us from the e-mail address we have on file. For privacy reasons, we cannot discuss the details of patron accounts over the telephone. Expired: Students must be currently enrolled in classes in order to be granted library privileges. Once they graduate, or if they fail to register on time in accord with the deadlines posted on LSUs academic calendar, their privileges expire. If they try to log in to their library account after that date, they will see an alert message informing them that their account has expired. Graduate students who have received a masters degree but are continuing on to get their PhD may also have their privileges expire earlier than expected. The library receives weekly updates on student status from the Registrars Office. Once the semester has begun, if students register during the week, their accounts will not be updated and their privileges extended in the system until the following Monday morning. Blocked: Users with overdue recalled books will have their accounts blocked by the system. Their accounts will remain blocked until the book is returned. The system will not permit staff members to override blocks or to renew books that have been recalled. The only way to remove a block from an account is to return the materials. Barred: Users can be barred from using library materials for a number of reasons, the most common being that they have been billed for lost items. They can also be barred if they resign from the university, if their classes are purged, or for flagrant violations of library policy. If they try to log into their account after they have been barred, they will receive an alert message that tells them that they have been barred. Answered by: Access Services Staff

Variation in the catch rate and distribution of three important commercial Spanish mackerel (Commerson: Niphonius: Guttatus) related to ENSO events around the waters off Taiwan
Spanish mackerel species are migratory species, also are highly commercially valuable in Taiwan. However, in recent years, climate change and variability have influenced oceanographic conditions, substantially impacting the population dynamics of pelagic species. This study developed weighted habitat suitability index models for three crucial Scomberomorus species—Scomberomorus commerson, Scomberomorus niphonius, and Scomberomorus guttatus—in the waters off Taiwan. Remote sensing data including sea surface temperature, sea surface chlorophyll-a, sea surface salinity, and sea surface height, along with voyage data records that included detailed catch data from Taiwanese drift gillnet fisheries were collected during 2011–2019. The primary fishing grounds for S. commerson are located in the central to southwestern Taiwan Strait, while S. niphonius and S. guttatus are mainly found in the coastal waters off western Taiwan. In autumn, the oceanographic factor preferences are relatively similar among Scomberomorus species, with sea surface temperature being the primary influencing factor. Sea surface height turns to the main influencing factor in winter. Based on the results of the weighted habitat suitability model, we found seasonal differences in habitat preferences and ranges. There is more pronounced overlap in potential habitat in autumn and partial separate condition in potential habitat in winter among Scomberomorus species. Further exploration of the spatiotemporal distribution dynamics of Scomberomorus species under different ENSO periods revealed that during La Niña periods, the potential habitat ranges are broader and extend further south. In contrast, during El Niño periods, and the potential habitat ranges contract northward. Habitat suitable index model may be a useful approach for evaluating possible changes in habitat suitability resulting from climate change or other oceanographic phenomena and in offering suggestions for fishery scientific management.
Improving students’ attendance in Values Education classes during Catch-Up Fridays through collaborative game-based learning
This study aimed to improve the attendance of 36 Grade 8 Santan students in Values Education classes during Catch-Up Fridays through Collaborative Game-Based Learning. Using a mixed-method design, the study evaluated attendance trends before and after the intervention. Quantitative data were collected from School Form 2 (SF2) to measure attendance, and a paired sample t-test revealed a significant increase in mean attendance values, from 3.47 to 4.47, with a p-value of less than 0.05, confirming the intervention's effectiveness. Qualitative data were gathered through a focus group discussion (FGD) and a thematic analysis following Braun and Clarke's (2006) framework was used to examine how students find Collaborative Game-Based Learning as an intervention to improve attendance. Students’ responses from the FGD showed that Collaborative Game-Based fosters student engagement, enhances participation, and creates a fun and dynamic learning environment.
Significant uncertainty in bark beetle trap catches due to varying pheromone release from dispensers and local trap position
Tree-killing bark beetles are important pests severely affecting forests worldwide. An understanding of their spatio-temporal swarming intensity, typically assessed with pheromone traps, is crucial to guide management actions. While multiple factors have been shown to affect trap catches, we lack knowledge of the effects of inherent dispenser-dependent variations in pheromone release and of local trap position. In a laboratory experiment, we assessed the influence of filling level and temperature on the release rate (Rr) of three commonly used pheromone dispenser products for bark beetles (Pheroprax®, Chalcoprax®, Curviwit®). By conducting a complementary field study at two sites in Germany, we quantified the effect of varying Rr of Pheroprax® and trap position on the number of Ips typographus trapped. Rr of all three products correlated with temperature and strongly declined during the application period in Pheroprax® and Chalcoprax®. In the field, both the temporal variability in filling level and the ambient temperature similarly affected Rr, which in combination led to a fivefold change in trap catches. Additionally, catches varied by a similar magnitude due to local trap position, partly explained by the distance from the forest edge. The large uncertainties found in pheromone trap catches, which may also apply to other pest species, highlight the need for careful interpretation (or correction) of trap data. As a potential improvement of monitoring, we propose swarming models to facilitate more accurate predictions of infestation risk by (i) incorporating uncertainties arising from trap-related factors and (ii) providing continuous information on the spatio-temporal abundance of pest species.
Factors influence on the catch efficiency of abandoned, lost or otherwise discarded fishing gears (ALDFG): a case from Turkish inland fisheries
This study aimed to evaluate the effects of various operational and environmental factors on the ghost fishing efficiency of Abandoned, Lost or Otherwise Discarded Fishing Gears (ALDFGs). A generalized linear mixed model (GLMM) was employed to estimate the influence of selected operational and environmental variables on ALDFG catch rates. In the experimental ALDFGs, crustaceans represented the majority (86%) of caught by weight. In terms of catch quantity, no significant difference was found between monofilament and multifilament nets, or between gill nets and trammel nets (P > 0.05). However, soak time had a statistically significant effect on fish catch rates. For crustaceans, fyke nets yielded significantly fewer individuals compared to set nets. When considering the total catch, no significant difference was observed between gill nets and trammel nets or between mono and multifilament nets. However, fyke nets again produced significantly lower catch rates than the other gear types. These findings indicate that ALDFGs continue to pose a substantial threat to aquatic ecosystems, with the level of impact varying depending on species composition, gear type, and net rigging technique, despite their diminishing effectiveness over time.
The Opportunity Makers: How a Diverse Group of Public Schools Helps Students Catch Up -- And How Far More Can. Paths of Opportunity Series
In this paper, TNTP reveals five interconnected factors of mobility that young people need in order to thrive: a strong academic foundation, career-connected learning, opportunities to build social capital, personal support in their lives, and civic engagement in their community. These five factors do not work in isolation. Instead, they must be woven together into coherent support for young people, with coordinated efforts from the many systems that shape young people's lives. TNTP's new Research Center of Excellence is currently studying each factor of mobility and, critically, exploring the connections between them. This report, "The Opportunity Makers," is the first chapter of ongoing mobility research. It identifies how to build a strong academic foundation for all students, particularly for historically marginalized groups like students of color, students experiencing poverty, multilingual learners, students with disabilities, and students with learning and thinking differences.
Gotta Catch' Em All: Utilization of Improvised Insect Traps as Home-Based Biology Experiment for Insect Taxonomy
Classifying, naming, and identifying insects have been complicated topics among science teachers and students. This problem is due to the highly technical collection protocols, safekeeping procedures, the unavailability of appropriate learning resources, and the closure of school laboratories and facilities due to the COVID-19 pandemic. Using the remote learning setup, this study utilized Improvised Insect Traps (IITs) to provide an authentic learning experience in teaching and learning insect taxonomy at home. The study aimed to determine the effects of using IITs on students' self-efficacy beliefs and perceived levels of engagement. In this quasi-experimental study, 42 students designed and developed their improvised insect traps. Insect collection and classification were accomplished within four weeks. A 20-item validated survey questionnaire on self-efficacy and engagement levels was administered via Google Forms. Students' feedback was gathered using virtual focus group discussions and open-ended questions. Results revealed that IITs effectively improved students' self-efficacy beliefs (Z=0.033, p-value=0.022, g=0.68), while no improvement was noted in students' perceived levels of engagement (Z=0.143, p-value=0.188, g=0.07) in teaching and learning insect taxonomy. Moreover, students' feedback and responses were classified as Affordances or Constraints. Subthemes such as motivation, satisfaction, authentic learning, safety, and parental involvement were generated in the thematic analysis. Overall, this study found that the IITs activity is relevant in teaching insect taxonomy and delivering practical learning experiences among students in a distance learning modality.
Soil cultivation methods rather than catch crop species enhance bacterial diversity in soil over a three-year experiment.
Growing catch crops can improve soil health by enhancing microbial diversity, but their impact may be constrained by how they are managed. This study examined the effects of different catch crop species and soil cultivation methods on bacterial and fungal diversity, and total soil microbial biomass. A 3-year field experiment on Luvi-haplic Chernozem included two catch crop species and five mixtures (further catch crop species) and three cultivation methods (ploughing, reduced tillage and no tillage), resulting in 21 treatments (7 catch crop species x 3 soil cultivations). Soil samples (0–15 cm depth) were collected annually in autumn and spring since 2021 to 2024. Microbial biomass was assessed using the chloroform fumigation extraction method, while fungal and bacterial diversity was analysed by amplifying and sequencing the ITS2 region of rDNA and the V4 region of the 16 S rRNA gene for fungi and bacteria, respectively, via Illumina paired-end amplicon sequencing. Soil cultivation methods affected bacterial diversity, with reduced tillage showing higher diversity and evenness than ploughing, though neither differed from no-till. However, no effect was observed on fungal diversity, including AM fungi, or microbial biomass. Catch crop species did not significantly impact microbial diversity or biomass. Neither cultivation method nor catch crop species influenced the ratios of functional trophic groups, such as pathogens, saprotrophs or symbionts. This study underscores the critical role of soil management practices—especially reduced tillage—in promoting soil health, primarily through the enhancement of bacterial diversity.
