Abstract Armadillos are bitten by several species of flea. Females the genus Tunga penetrate epidermis and when in place fertilised males, after which abdomen swells enormously to form a ‘neosome’. Within penetrans group, T. perforans , makes lesions that perforate osteoderms within integument ~3 mm diameter cavities occupied discoid neosome. We examined these carapace material from animals had died wild see whether we could recruit evidence as how they may be generated, either insect or host. studied one without such lesions, nine‐banded armadillo Dasypus novemcinctus two with, greater hairy Chaetophractus villosus southern three‐banded Tolypeutes matacus both showing characteristic ‘flea bite’ holes external surfaces osteoderms. Samples were three‐dimensional backscattered electron mode scanning microscopy X‐ray microtomography. Both methods showed resorption pit complexes those made osteoclasts active bone resorption. Lesions involved syndesmoses (sutures) between adjacent bones central regions Many extensive repair infilling with new bone. conclude neosome creates local host response causes resorption, creating space it can grow.

Biodiversity monitoring projects comprise key conservation strategies established to minimize biodiversity loss. Particularly, community-based have recently been implemented worldwide. This approach favors three pillars: provision of information on monitored resource through time, local people's empowerment, and management practices. We conducted a systematic literature review identify all past current terrestrial game fauna in the tropics, specifically examined seventeen those terms costs, interruption effectiveness. identified total 52 projects, mostly located Amazon. revealed an annual cost US$0.24/hectare/project, with most these initiatives interrupted due lack funding. also noticed that absence data analyses comprised main obstacle for assessment while empowerment was hampered by intensive participation at different stages monitoring. Finally, we observed actions resulted community rules applications, including bylaws governing use. highlight programs can be more effective if they engage people stages, build solid partnerships ensure long-term funding translate outcomes into practices fauna.

The use of data-based species distribution models (SDMs) has increased significantly in recent years. However, studies determining the minimum requirements occurrence sites from ecological monitoring datasets used modelling remain insufficient. Therefore, this study proposed a framework to determine threshold for SDMs by assessing compliance with Benford's law. test verified that national-scale freshwater fish dataset was natural and reliable. Results derived true skill statistics (TSS) determined number reliable 20 TSS value 0.793 an overall accuracy 0.804. Benford shown be useful tool swift efficient evaluation reliability datasets, or determination before modelling. Further regarding method's transferability other validation using SDM performance are required. Overall, demonstrates applied can derive universal model-independent SDMs.

How ecological and evolutionary factors affect small mammal diversity in arid regions remains largely unknown. Here, we combined the largest phylogeny occurrence dataset of Gerbillinae desert rodents to explore underlying shaping present-day distribution patterns. In particular, analyzed relative contributions on their species using a variety models. Additionally, inferred ancestral range possible dispersal scenarios estimated diversification rate Gerbillinae. We found that likely originated Horn Africa Middle Miocene then dispersed diversified across northern southern western central Asia, forming current pattern. Multiple jointly determine spatial pattern diversity, but (evolutionary time speciation rate) habitat filtering were most important explaining variation richness.
