E. Hoske 1980 Journal Pozo de Petroleo, 7mi N. Berriozabal, Chiapas, Mexico December Arose ~0630. Heavy dew, clear skies. Trap line in rocky area yielded only 3 P. mexicanus. Trap line in forest near trail yielded 1 Tylomys (sp.), 1 Oryzomys (sp.), 4 P. mexicanus (and 3 traps that didn't close but were visited. Duke had similar good results on all 4 of his lines (5-4-9-6 captures): 2 Heteromys desmarestinus 1 Oryzomys sp., 7 Tylomys (sp.), 1 Scotinomys (sp.), 13 P. mexicanus. An Artibeus (sp) was found in the mist net this morning, as well. After breakfast, David went looking for salamanders while Duke + I took tissue samples + skinned 18 of the P. mexicanus. Put skins aside for stuffing later. Also took tissues, skinned, and stuffed 7 Tylomys w/ David's help. ~1530 went to set out more traps -- all three of us went to the same area (where Duke caught the Heteromys), so our trap lines ended up crossing and running into each other - very frustrating. I set one line there, Duke set 3, David one. David set another line further down the road toward Berriozabal, I linked further down the trail away from camp. When I reached another area of mature-looking forest, hiked in and set 20 traps. Area has large trees, dense canopy (broadleaf), dense viny growth, herbaceous ground cover, leaf litter floor, many mossy rocks, some logs -- similar in overall appearance to area trapped last night[only farther
