“…A possible reason might be that maternity colonies are often found close to bodies of water and in proximity to promising foraging areas (Korine et al, 2013; Racey, 1998), often close to figs, as females require greater amounts of calcium (Nelson et al, 2005). Also, females might be more active during foraging since they have higher energy requirements for reproduction (Bohlender et al, 2018). Females thus might occur in higher densities, while males could forage over larger distances, resulting in lower densities and therefore lower capture probability.…”

Patterns of species abundance and diversity have amazed ecologists for a long time (Hawkins, 2001;Rosenzweig, 1995). There are 36 biodiversity hotspots recognized in the world (Hrdina & Romportl, 2017), many of which are under severe human pressures (Myers et al., 2000). Mt. Kilimanjaro is one of such biodiversity hotspots as well as the highest mountain in Africa, harboring an extraordinary diversity of pristine and altered habitats distributed over a broad elevational range (Burgess et al., 2007;Newmark & McNeally, 2018). Kilimanjaro's climate and land use gradients affect species richness, since species survival depends also on the ability to use forest fragments and surrounding landscape matrices as foraging habitats. As the sole source of running water in the region Mt. Kilimanjaro is also

“…On Trinidad embryos carried by these bats go into a diapause late in the wet season. Because Carollia is a food generalist (feeding on fruits, nectar/pollen and insects), it seems unlikely that food availability should be a problem at that time of the year [30][31][32][33]. Rather, it appears that these bats have evolved an annual cycle that anticipates when advanced gestation, lactation, rapid neonatal growth, and the initiation of new pregnancies might be optimally timed some months into the future, after completion of the diapause.…”

Pregnancy has been studied in Carollia perspicillata bred in captivity or collected from a reproductively-synchronized wild population on Trinidad, West Indies. In both situations, periods of postimplantational embryonic diapause were sometimes observed. In captivity, this was induced by stress, or once-weekly periods of food deprivation, and resulted in gestation periods of highly variable duration (105-237 days). The normal gestation period for this species is 113-120 days. In the wild, Carollia exhibits two synchronized pregnancy periods. One includes a diapause of at least 44-50 days, but probably somewhat longer, while the other is of normal length. The diapause occurs at the primitive streak stage of development. The postimplantational timing of the diapause is associated with multiple other reproductive specializations, all of which seem to be intended to facilitate blastocyst attachment very soon after entry into the uterus, within a preferred implantation zone. Blastocysts of this species were never observed to have passed that zone or to have a prolonged, free-floating period in the main uterine cavity. This facilitates placental development within an optimally vascularized part of the uterus and the eventual production of a large, highly precocious infant. Comparative immunocytochemical and ultrastructural studies of normal versus delayed pregnancies suggest that inadequate trophoblastic differentiation within the developing placenta may play an important role in maintaining the diapause. In part this may be responsible for delayed invasion of the embryonic side of the placenta by vascularized allantoic mesenchyme. The diapause is also associated with greatly increased trophoblastic invasiveness of unknown significance.

“… Piper is also a common element in the understory of Neotropical forests ( Gentry 1990 ; Draper et al 2021 ). Species of Piper are a key resource for bats of the genus Carollia ( Fleming 2004 ; Bohlender et al 2018 ; Yohe et al 2021 ), and they are a critical element that supports diverse trophic networks that involve moths and parasitoid wasps ( Wilson et al 2012 ; Slinn et al 2018 ). Piper ’s enormous diversity of secondary metabolites is critical for their coexistence ( Salazar et al 2016a , 2016b ) and diversification ( Massad et al 2022 ).…”
