“…The ratio of species with dry fruits to those with fleshy fruits has been found to be similar in tree species from Southern Africa (Knight & Siegfried 1983). Many other studies, however, have shown that species with dry fruits outnumber those with fleshy fruits in varying proportions (Gordon 1998, Silva & Rodal 2009, Silva et al 2013, Possete et al 2015 including in our survey where the number of species with dry fruits was more than twice the number with fleshy fruits. A phylogenetic study revealed that the majority of plant families produce dry fruits (Fleming 1991).…”

“…Septicidal capsules, legumes, and schizocarps also tended to be brown. In fact, several studies have shown that most dry fruits are brown (López & Ramírez 1989, Knight and Siegfried 1983, Parisca & Ramírez 1989, Carpenter et al 2003, Ibarra-Manríquez & Cornejo-Tenorio 2010, Possete et al 2015. The pods and capsules surveyed in different tropical forests were also mostly brown (Selwyn & Parthasarathy 2006, Ibarra-Manríquez & Cornejo-Tenorio 2010.…”

“…Low frequencies of fleshy fruits among tree and vine species, and higher frequencies among shrubs have also been associated with dry forests compared to wetter ones (Willson et al 1989). The high frequencies of dry fruits and the minimal occurrence of fleshy fruits among annual herbs have been found repeatedly (Willson et al 1989, Possete et al 2015, and seem to be influenced by the low energetic cost and shorter development period of dry fruits, which are also undemanding of water and energy to complete growth. The strong associations found between Biota Neotropica 21(4): e20211238, 2021 https://doi.org/10.1590/1676-0611-BN-2021-1238 http://www.scielo.br/bn dry fruits (dehiscent and indehiscent) and herbs may be related to the relatively small plant size, short lived life cycle, and inexpensive fruits.…”

“…In fact, plant-seed dispersal networks show low levels of specificity ( Blüthgen et al 2007), although drupes and berries favored by birds for seed dispersal are more likely to be brightly colored, whereas those eaten principally by mammals tend to be yellow or green (Knight & Siegfried 1983, Willson et al 1989, Voigt et al 2004, Galetti et al 2011. Yellow-fleshy fruits are generally found in relatively low frequencies at the community level (Willson & Thompson 1982, Chen et al 2004, Possete et al 2015. In this study we recorded comparatively low numbers of yellow-fruited species, despite the inclusion of a few yellow-dry fruits in the plant species examined.…”

“…However, morphological fruit types of certain clades are, in many cases, modified by ecological factors and by the potential relationships between fruit morphology and functional groups, such as life form, carbon metabolism pathway, and epiphytism. Regarding life form, herbaceous species tend to bear dry fruits, and woody species (shrubs and trees) fleshy fruits (Herrera 1984, Willson et al 1989, French 1991, Possete et al 2015, Wotton & McAlpine 2015; vines may exhibit variation according to forest type (Willson et al 1989, Possete et al 2015. Fruit types, and fruit and seed colors are also representative of successional stages, with dry fruits being more abundant in open vegetation communities (e.g.…”

The associations between morphological fruit types, fruit and seed colors, and functional plant traits: life forms, epiphytism, physiology, nutritional relationships, fruit phenology, and successional stage, were determined for 1,139 plant species from contrasting plant communities. Texture and dehiscence were closely related. Dehiscence is largely associated with dry tissues; indehiscence, however, is an attribute of both dry and fleshy fruits. The number of morphological fruit types was 28 or 55 for Gray's and Spjut's classifications, respectively. Fruits were predominantly dark in color (brown, purple-black, black or green), whilst seeds had both dark and light colors (brown, beige, or black). The most representative associations were mainly found between the more abundant fruit types and the colors most common. Asymmetries in the level of specialization, whereby less common fruit and seed colors tended to be associated with the most common fruit types, were also found. Fleshy fruits showed more variation as regards their coloration, and only drupes and berries showed a tendency towards a specific color: purple-black. The relationships among fruit type and color, seed color, and functional plant traits revealed the following trends: trees produced both fleshy and dry fruits; shrubs produced fleshy fruits; and herbaceous species, dry fruits. Woody species tended to have dark or bright colors, depending on their seed dispersal mechanisms and phylogenetic relations. Epiphytes were associated with dry-dehiscent fruits and brown seeds, and parasitic-hemiparasitic species had predominantly fleshy-indehiscent fruits. Pioneer species were more likely to have dry fruits, whereas fleshy fruits tended to be more frequent in late successional stage species. The C4 species, mostly herbs, had mainly one-seeded dry fruits, but multi-seeded fruits in succulent-CAM species showed morphologically diverse fruit types. Unripe and ripe fruits showed seasonal changes, especially during the rainy-dry transition period for the most abundant morphological fruit types, dry fruits during the dry period and fleshy fruited species was positively associated with the rainy season. All these trends are discussed with regard to their environmental significance and the relationships between fruit morphology, colors and functional groups. .

Questions: Park forests are shaped by extensive cattle ranching in the transition between natural riverine forests and open grasslands. The underlying mechanisms driving tree regeneration have not been studied, however, they determine biodiversity, sustainability and multifunctionality of these ecosystems. We explored patterns of tree regeneration by analyzing nurse-beneficiary interactions and tree community composition.
