articleOpen accessCockroaches are vectors of pathogens and parasites that pose public health risks, especially in developing countries with poor hygiene and inadequate infrastructure. This study aimed to identify the household factors associated with the occurrence of cockroaches and the helminth parasites they carry in a rural community. Data on household infrastructure, presence of domestic animals, and insect control methods were collected from 70 households in rural Guatemala. Cockroaches were captured using traps and manually. A Generalized Linear Mixed Model revealed that households with concrete roofs had 94% lower abundance of cockroaches than those with metal sheet roofs, while the presence of cats increased cockroach abundance by 2.6 times (p < 0.05). Six genera of helminths, including the acanthocephalan zoonotic parasite Moniliformis moniliformis, were identified, marking the first report of such parasites in household cockroaches in Guatemala. These results highlight the need for improved housing infrastructure and integrated pest management strategies to mitigate the risks associated with cockroach-borne parasites in vulnerable communities.
Assessing sexual dimorphism in the common vampire bat, Desmodus rotundus
PLoS ONE · 2026-01-21
articleOpen accessSenior authorSexual dimorphism in bats is understudied, with conflicting evidence across species and geographic regions. For Desmodus rotundus, the common vampire bat, previous reports on morphological sex differences have been inconsistent. This study aimed to assess sexual dimorphism in D. rotundus using a combination of contemporary field measurements and historical museum specimens. We analyzed six morphometric traits, including body mass, head length, body length, tibia length, ear length, and forearm length. Data were collected from 46 wild-captured individuals from five locations across Colombia in South America. Additionally, forearm length was examined in an expanded dataset of 490 specimens, including additional 444 individuals from museum vouchers collected over the past century. Principal components analysis and hierarchical clustering of the six-trait dataset showed patterns of differentiation between sexes, with partial overlap. Forearm length, analyzed independently in the full 490-specimen dataset, showed strong evidence of sexual dimorphism. Females had significantly longer forearms (mean = 61.8 mm) than males (mean = 58.5 mm), with non-overlapping 95% confidence intervals and a highly significant t-test result (t = -12.68, p < 2 × 10 ⁻ ¹⁶). Sex explained 25.7% of the variation in forearm length (R² = 0.26). Tibia length also differed significantly between sexes of the wild-catch individuals (p = 0.004), with females exhibiting greater values. Comparisons between museum specimens (historical) and wild-caught specimens (contemporary) showed no significant differences across time in either sex. Among females, the difference was not significant (t = -0.93, df = 208, p = 0.355), and the same was true for males (t = -0.01, df = 278, p = 0.992). A follow-up MANOVA on the six morphometric traits indicated a significant effect of sex (Pillai's trace = 0.389, approx. F(6,39)=4.14, p < 2.2 × 10 ⁻ ¹⁶). After correcting for multiple comparisons, significant sexual dimorphism remained for forearm and tibia lengths, with forearm showing the strongest signal. These findings provide robust support for modest but consistent female-biased dimorphism in D. rotundus. The use of both multivariate and univariate analysis, combined with long-term historical data, enhanced the reliability of signals detected regarding morphological differences. Desmodus rotundus play a role as a primary reservoir for zoonotic viruses, has potential relevance in biomedical research, and provides ecosystem services. Understanding sex-based morphological variation is critical to inform public health, ecology, and biological conservation strategies. Females were consistently larger than males, but segregation was not absolute, with some individuals falling outside the expected data range for their sex. This study contributes to a clearer understanding of morphological variation and lays the groundwork for future research into the ecological and evolutionary drivers of dimorphism in bats.
Drivers of rabies virus spillover risk from vampire bats to livestock in Colombia
PLoS neglected tropical diseases · 2025-09-26 · 1 citations
articleOpen accessSenior authorCorrespondingBACKGROUND: Rabies is an acute and progressive viral zoonotic disease of the nervous system, which widely affects domestic animals in Latin America. Vampire bat-borne rabies virus (RABV) has significant negative impacts on the livestock industry via animal mortality. Nevertheless, the landscape level factors that facilitate or limit RABV transmission from vampire bats to livestock remain elusive. METHODS: To determine how abiotic and biotic factors modulate RABV spillover from vampire bats to livestock, we assessed the role of different landscape variables on the occurrence of RABV spillover from Desmodus rotundus to livestock in Colombia. Using ecological niche modeling as the theoretical and analytical framework, we analyzed ecological and epidemiological RABV data to reconstruct spillover transmission events. RESULTS: Anthropogenic variables including livestock and human density were consistently selected as predictors of RABV spillover from vampire bats to livestock. Cattle density had the highest average relative contribution to final ecological niche models (64.7%). We also found improvement of RABV spillover risk estimates when sampling bias in the form of cattle density was used in the modeling process. High risk for RABV spillover (0.75-0.98) was consistently predicted in the Caribbean region of Colombia. Nevertheless, more widespread moderate RABV spillover risk was predicted more broadly across the country when sampling bias was accounted for. CONCLUSION: Our modelling effort revealed that variable selection and use of bias surface have tractable impacts on final projections of spillover risk. Our results also indicate that human activity drives RABV spillover risk to a greater extent than ecological or climatological factors. Results from this study provide important information about landscape conditions linked to RABV transmission risk, where livestock vaccination should be prioritized.
A practical framework for a theory-driven ecological niche modeling workflow
The Innovation Life · 2025-01-01 · 1 citations
articleOpen accessSenior author<p>Distributional ecology provides a multidimensional understanding of the complex ecological, evolutionary, and biogeographic factors shaping species’ distributions. Distributional ecology uses ecological niche modeling (ENM) serving as a quantitative approach to estimate species’ ecological niches and their manifestation as likely geographic ranges. Its application is particularly crucial for invasive species, where predicting their potential spread is paramount. An important ongoing debate is how to choose a suitable algorithm and its parameters to perform models well. Nevertheless, a main question should be what ecological niche is being reconstructed, the realized or fundamental? Current protocols and emergent evaluation metrics have only focused on reconstructions of the realized niche, driven by the unbalanced credibility between present and pseudo-absence (or background) occurrences, which often prioritize fitting to the available data while overlooking species’ physiological and ecological constraints. Our findings indicate that generalized linear models (GLMs) effectively reconstruct most of the fundamental niche, whereas hypervolume methods, such as kernel density estimation (KDE) and Marble Algorithm (MA), tend to overfit the data and perform poorly. Similarly, Maxent exhibits limitations in characterizing the fundamental niche. We present a conceptual framework to guide assumptions and workflows in ENM applications to facilitate model selection and interpretation.</p>

articleDespite the large body of literature on avian migratory behavior, there is little information about stopover sites during bird movement, including the population-level drivers of breeding grounds and wintering grounds. Stopovers play an essential role in bird migratory site chains for energy supply and rest. There is an urgent need to identify and protect stopover sites to secure the long-term sustainability of migratory network connectivity and stability. To address this challenge, we reconstructed a migration network and identified geographic hotspots denoted as stopover sites. And we analyzed the high-density population movements of 52 focal migratory bird species using comprehensive observation data from eBird through PageRank algorithm. Furthermore, potential alternative stopover sites were explored using a word embedding technique based on geo-functional similarity. Our study was conducted in North and Central America during a three-year period and revealed three key stopover areas, including Florida peninsula and its inland, the region of Central America, and the region near Puget Sound. Results from this study can be used for conservation prioritization guidance, active surveillance of bird pathogens, and bird management.

En conclusión, la investigación resalta la necesidad de fortalecer la educación ambiental y las estrategias de conservación en estos ecosistemas, promoviendo acciones que equilibren el desarrollo productivo con la protección de la biodiversidad y la sostenibilidad del humedal.
Rabies transmitted from vampires to cattle: An overview
PLoS ONE · 2025-01-13 · 14 citations
articleOpen accessSenior authorCorrespondingRabies is a zoonotic infectious disease of global distribution that impacts human and animal health. In rural Latin America, rabies negatively impacts food security and the economy due to losses in livestock production. The common vampire bat, Desmodus rotundus, is the main reservoir and transmitter of rabies virus (RABV) to domestic animals in Latin America. Desmodus rotundus RABV is known to impact the cattle industry, from small farmers to large corporations. We assessed the main patterns of rabies in cattle attributed to D. rotundus RABV across Latin America. Epidemiological data on rabies from Latin America were collected from the Pan American Health Organization spanning the 1970-2023 period. Analyses revealed an average of 450 outbreaks annually for the countries where D. rotundus is distributed, with at least 6 animals dying in each outbreak. Brazil, Colombia, Peru, and Mexico were the Latin American countries with the highest number of rabies outbreaks during the study period and are the most affected countries in recent years. Findings suggest a re-emergence of bat-borne rabies in the region with more outbreaks reported in recent years, especially during the 2003-2020 period. Rabies outbreaks in cattle in the 2000-2020 period were significantly more frequent than in previous decades, with an increase in cross-species transmission after 2002. The size of outbreaks, however, was smaller in recent years, involving lower cattle mortality. Peru, El Salvador, and Brazil showed a strong association (R = 0.73, p = 0.01) between rabies incidence in D. rotundus (rates per million humans: 1.61, 0.94, and 1.09, respectively) and rabies outbreaks in cattle (rates per million cattle: 465.85, 351.01, and 48.22, respectively). A sustained, standardized, and widespread monitoring of D. rotundus demography and health could serve to inform an early warning system for the early detection of RABV and other bat-borne pathogens in Latin America. Current data can be used to forecast when, where, and in which intensity RABV outbreaks are more likely to occur in subtropical and tropical Latin America. A decrease in the size of outbreaks could suggest that strategies for epidemic management (e.g., education, early diagnosis, vaccination) have been effective. The increase in the number of outbreaks could suggest that the factors facilitating cross-species transmission could be on the rise.
Rodents of Chile: a brief appraisal of their conservation status and ecological significance
ZooKeys · 2025-10-01 · 2 citations
reviewOpen accessSenior authorRodentia is the most widely distributed, diverse, and numerous order of the class Mammalia. Nevertheless, rodents are poorly studied in terms of their conservation compared to other mammalian orders. Chile has one of the highest rates of extinction risk in the world for mammals (20%), where rodents have the highest risk (32%). The data of threatened rodent species is not comprehensive, as many species are still classified as data deficient. This lack of information could mean that the actual number of threatened species is higher than currently recognized. Using different databases, the biogeography, conservation status, ecological roles of rodent species in Chile are updated and described, and their potential zoonotic implication discussed. Results revealed that rodent species richness is highest in the northern and central-southern regions of Chile, where fewer protected areas exist, suggesting an inefficient role of public protected areas for the conservation of rodents and potentially other taxa. The conservation classification by the Chilean government did not match the conservation status from international classifications, revealing poor information for several species at national level. Functional traits of the species studied suggest that rodents are good predictors of ecosystem health due to their rapid life cycles and wide distribution, although distribution was predictive for only some species. Our results indicated that better information on the distribution and rodent species richness provide opportunities to understand complex rodent-borne diseases such as hantavirus. This study validates the use of rodents as indicators to assess ecosystem health and design effective biodiversity conservation plans.
The Niche-Center Relationship in Ecological Niche Modeling
2025-12-11
articleOpen accessSenior authorThe niche-center relationship posits that organisms’ fitness is highest at the center of their fundamental ecological niche, an assumption often implicit in ecological niche modeling. Nevertheless, empirical support for the niche-center relationship at the species level is often inconsistent, potentially due to confounding factors such as biotic interactions, dispersal limitations, habitat degradation, and sampling biases. Confounding factors could obscure the signals of the niche-center relationship between abiotic conditions and population performance. To address these challenges, we present a supra-specific approach, hypothesizing that analyzing the niche-center relationship at a higher taxonomic level can better approximate the fundamental ecological niche of a lineage and reveal more robust macroecological patterns. We illustrate this approach using a case study on the North American rodent genus Peromyscus, leveraging a comprehensive dataset from the Global Biodiversity Information Facility and the National Ecological Observatory Network. We defined environmental space using principal component analysis of bioclimatic variables. We assessed fitness based on Peromyscus occupancy. The niche-center relationship was not supported by individual species; a strong and statistically significant negative relationship emerged at the genus level. Occupancy frequency was highest in environmental conditions closest to the genus’s niche centroid. This ecological niche supra-specific modeling framework effectively filters species-level realized niche noise to estimate better proxies of fundamental ecological niches of lineages, assess niche-center relationships, and better understand organisms’ response to global change, dispersal limitations, and evolution.
