Nutritional and reproductive dynamics of moose near their southern range limit

open access: yesThe Journal of Wildlife Management, EarlyView.
Though southern moose (Alces alces) had relatively low seasonal fluctuations in body fat, their condition was positively associated with pregnancy and adult survival but did not influence recruitment of young. We demonstrated clear signs of nutritional limitation and unexpected patterns of reproductive performance that may be unique to moose living at ...

Spatial and temporal variation in survival of female wild turkeys

open access: yesThe Journal of Wildlife Management, EarlyView.
We monitored 370 female wild turkeys across North Carolina's 3 ecoregions from 2020‐2022 to understand factors influencing their survival. Female survival varied by ecoregion and behavior state, with the incubation period having the lowest survival rates. None of the land cover variables affected survival.

Occurrence, morphology and growth of understory saplings in Swedish forests [PDF]

open access: yes, 2004
Growing demands for a multipurpose forestry leads to increased use of silvicultural systems that avoid clear-cutting. Regeneration in such systems is based on establishment and ingrowth of new seedlings under a more or less closed canopy.

MÉTODOS DE DETECÇÃO, TRANSMISSÃO E PATOGENICIDADE DE Fusarium spp. EM SEMENTES DE Pinus taeda

open access: yesCiência Florestal, 2017
The root rots (RR), caused by the Fusarium spp., causes loss of seedling in the nursery that show, initially, discoloration of the needles to a yellowish-green tone followed by apical curvature, wilt and the consequent death of the seedling.
