#Phenology of Richeria grandis Vahl: A dioecious species with wide geographical distribution and unique environmental specificity

Cristiane Coelho de Moura et al
doi.org/10.1111/1442...

conservation/ forest islands/ phenophase/ Phyllanthaceae/ plant physiology
icheria grandis exhibits synchronized and highly seasonal reproductive phenology, emphasizing its strong dependence on local climate dynamics. The species' supra-annual fruit production and evergreen vegetative habit highlight adaptive strategies for resource utilization and ecosystem balance. Phenological insights into Richeria grandis provide critical data for conservation strategies amidst global climate change impacts.

invasive grass/ palisadegrass/ pequi tree/ savannah/ weed competition
The present study provides an approach to the occurrence of this invasive grass and its density in terms of competitive aspects with Caryocar brasiliense. A biological approach with physiological, growth, and nutritional assessments is used to demonstrate the effects of grass coexistence on tree species and prove the problem of this invader for the conservation and cultivation of C. brasiliense.

Mucuna macrocarpa/ nonflying mammal/ #pollination/ tropical Asia
Volatile compounds of Mucuna macrocarpa were collected from four regions with different pollinators (a macaque, bat, squirrel, and two squirrel species, respectively), using the dynamic head-space method. In total, 112 volatile compounds were identified, varying from 14 to 63 compounds in each flower. Several flowers did not contain the sulfur compounds that are said to attract mammals, particularly nectar-feeding bats.

「規格破り：ブラジル半乾燥地域の樹木種Hymanaea stigonocarpaにおける種子サイズと種子数のトレードオフの欠如」
#OpenAccess

AE💬ブラジルの半乾燥地に生育する植物の種子生産数と種子サイズにおけるトレードオフについて検証した論文であり，果実のサイズによって不均一な選択圧が種子サイズに大きく関わっていることを検証した論文となっています．教科書で取り上げられている種子数，種子サイズのトレードオフは単純なものではなく，果実の大きさによって変わっているという点が検証されている興味深い論文です．
