E. HESKE 1980 Journal Cerro Moztol, Chiapas, Mexico dec. cont. second line I set W. of the road yielded only a single P. guatemalensis . This line was on slightly steeper terrain, more leaf-litter on floor, not as moist. May not be ideal Heteromys habitat, so will pull these traps later today. The line of 8 traps ~500m S. of our campsite yielded 1 P. guatemalensis , also. David (60 traps) caught 1 P. boylei . Duke caught 3 Heteromys nelsoni (80 traps) and 3 P. guatemalensis in the area near the 8 traps I set. After breakfast, Duke + I took tissue samples from and prepared study skins from 11 of the P. guatemalensis . This took from ~1000 - 1315. Had a quick lunch, then pulled all traps from the second W-of-road line. Took these to the area Duke had such good luck with this morning. Reset the 8 that were there plus two more, then added 20 on to the line. Habitat is mostly large pine, some broadleaf, but canopy not very thick. Disturbed areas in early successional stages bordering patches of forest. Many fallen logs, most covered with moss and ferns. Fairly dense low herbaceous ground cover. Floor covered with mixed pine needles and leaves. Returned to camp ~1630 and changed location of several traps on ravine line (hopefully for the better!) Added 4 more traps in the general area where the two Heteromys were caught. Coincidentally, the second Heteromys I caught was only one trap down from where I caught
