“Scrap Your Boilerplate” (SYB) is an established style of generic functional programming. The present paper reconstructs SYB within the Prolog language with the help of the univ operator and higher-order logic programming techniques. We pay attention to the particularities of Prolog. For instance, we deal with traversal of non-ground terms. We also develop an alternative model of SYB-like trave...

While it is known that intestinal parasite communities vary in their composition over time, there is a lack of studies addressing how variation in component communities (between-hosts) manifests in infracommunities (within-host) during the host lifespan. In this study, we investigate the changes in the intestinal parasite infracommunities in wild-living rufous mouse lemurs (Microcebus rufus) fr...

We analyzed temporal trends in mist-net capture rates of resident (n = 8) and overwintering Nearctic-Neotropical migrant (n = 3) bird species at two sites in montane broadleaf forest of the Sierra de Bahoruco, Dominican Republic, with the goal of providing quantitative information on population trends that could inform conservation assessments. We conducted sampling at least once annually durin...

UNLABELLED Longitudinal sampling for intestinal microbiota in wild animals is difficult, leading to a lack of information on bacterial dynamics occurring in nature. We studied how the composition of microbiota communities changed temporally in free-ranging small primates, rufous mouse lemurs (Microcebus rufus). We marked and recaptured mouse lemurs during their mating season in Ranomafana Natio...

Although recreational birdwatchers may benefit conservation by generating interest in birds, they may also have negative effects. One such potentially negative impact is the widespread use of recorded vocalizations, or "playback," to attract birds of interest, including range-restricted and threatened species. Although playback has been widely used to test hypotheses about the evolution of beha...

--Key assumptions and components of biophysical models of hummingbird licking that are central to current interpretations of plant-pollinator coevolution have not previously been verified. To test the realism of the models, I measured fine-scale parameters of a Rufous Hummingbird's (Selasphorus rufus) licking, including licking frequency and volume extracted per lick, with a photodetector array...
