    Abstract Many primatological studies do not assess direct indexes of food availability to make inferences about behavioral strategies. We related the diet and behavior of a group of Callicebus coimbrai in northeastern Brazil to fruit availability indexes and compared this pattern between seasons (direct and indirect assessment of food availability) to assess whether direct and indirect approaches detect similar ecological patterns. We monitored the study group for 33 months (5 days/month) via scan sampling. The monthly availability of fruits and new leaves was recorded in phenological transects. Fruit availability varied across years based on fruit prevalence, and timing and duration of the abundant seasons. We did not find evidence of a time-minimizing strategy, since C. coimbrai did not change its activity levels according to food availability. However, the negative relationship between foraging and fruit availability indicates that C. coimbrai can compensate for the lower fruit availability by increasing the search for alternative food sources. Monthly fruit consumption was positively correlated to fruit availability and negatively related to the consumption of other food items. However, the behavioral and feeding profiles did not vary between seasons and were not related to rainfall levels. Primate studies should directly relate behavioral and feeding profiles to fruit availability indices, thus avoiding using seasons as proxies of food availability.

    Abstract The name Cleome heptaphylla was published by Linnaeus in the second edition of Species plantarum and is still untypified. Analysis of the protologue and the associated pre‐Linnaean names indicated the absence of original material that could serve for lectotypification. A specimen from Miller's herbarium at BM is designated as its neotype. The neotype of C. heptaphylla is also original material of C. erucago, another untypified name in this group, published a few years later by Miller. Cleome erucago is lectotypified using the same specimen and, as such, it is a homotypic synonym of C. heptaphylla.

    Abstract During a botanical career that has spanned more than 35 years – almost all that time based at The New York Botanical Garden –, Wm. Wayt Thomas has participated in over 100 field expeditions and published almost 200 scientific works including two edited volumes, advised or co-advised 15 doctoral students, and became one of the world authorities on the systematics of the Cyperaceae. His research programs set down roots in Brazil, where his work has led to major advances in our knowledge of the flora of the Atlantic Coastal Forests and had significant impacts on conservation in that region. He has held leadership positions in the Organization for Flora Neotropica and the Species Plantarum Project. He has made perhaps his greatest contributions in forging productive international scientific collaborations and in mentoring young scientists who are becoming leaders in the botanical community – and who attest to his pivotal impacts on their professional lives.

    Abstract The family Cleomaceae is represented in the Neotropics by nine native lineages, with some of them currently recognized as distinct genera and others in need of clear delimitation. We present here a new phylogenetic hypothesis for the New World Cleomaceae with a more comprehensive sampling, including samples of 62 species with emphasis on Tarenaya and based on nrDNA ITS and cpDNA matK and ndhF. Six clades are supported: (1) a new clade comprising Cleome tenuis and Physostemon humilis; and five other previously identified clades: (2) the Dactylaena clade, including the monophyletic Dactylaena and the paraphyletic Physostemon and Mitostylis; (3) the Andean clade, comprising Andinocleome and Podandrogyne; (4) the Melidiscus clade; (5) the Cleoserrata clade, and (6) the Tarenaya clade; the last three corresponding to genera with the same name. The lineage comprising C. tenuis and P. humilis is strongly supported by morphological and molecular datasets, and a new genus, named Iltisiella, comprising these species is proposed here. Tarenaya is clearly demonstrated to be a monophyletic genus, corroborating previous analyses. We identify four subclades in its topology, and the relationships among the species in each subclade revealed to be moderately to strongly resolved. Furthermore, we conducted a historical biogeographical analysis of the New World Cleomaceae on time‐calibrated trees, and our results suggest an Oligocene origin at least 35.02 Mya with a MRCA distributed in Mesoamerica and the Northern Andes. For Tarenaya, our results suggest a Miocene origin at least 17 Mya, with the most recent common ancestor in the Chacoan and Atlantic Forest geographic areas.

    Abstract Tarenaya longicarpa, commonly known as “mussambê,” is a new species from South America. Iltis previously recognized it as a subspecies of Cleome spinosa Jacq. but never published the name. Molecular phylogenetic studies have confirmed this taxon as a distinct lineage from T. spinosa. In addition, the results of a revision of Tarenaya, now underway, corroborate the separation of T. longicarpa from T. spinosa s. s.

    Abstract BACKGROUND AND AIMS: The interpretation of ecosystem nitrogen isotopic patterns is subject to controversies since there are few surveys of signals along climate gradients within the same region. We determined the effects of a rainfall gradient, under high temperatures, on the soil and plant δ¹⁵N signals in Northeast Brazil. METHODS: Nitrogen, carbon and δ¹⁵N signals were determined from coastal perennial to subhumid and semiarid deciduous forests to savanna – deciduous forest transition. RESULTS: Soil C and N concentrations were linearly related and both related quadratically with mean annual rainfall while δ¹⁵N concentrations decreased with higher rainfall (16 to 4‰). Plant δ¹⁵N was 1–3‰ lower than soil δ¹⁵N (Δδ¹⁵N) in all areas. Only in the deciduous forests, leaves of target species had significantly lower¹⁵ N signals than those of non-fixing species, allowing estimation of fixation. CONCLUSIONS: In the perennial forests the low signals indicated that the¹⁵ N natural abundance method was not suitable to estimate fixation, while in the savanna – deciduous forest transition, high signals indicated that the legume species were not fixing. The smaller Δδ¹⁵N than those reported in cooler areas and the absence of rainfall effect indicates that, when high, temperature overrides the rainfall effect.

    Abstract Encounters between flowers and invertebrates are key events for the functioning of tropical forests. Assessing the structure of networks composed of the interactions between those partners leads to a better understanding of ecosystem functioning and the effects of environmental factors on ecological processes. Gathering such data is, however, costly and time-consuming, especially in the highly diverse tropics. We aimed to provide a comprehensive repository of available flower-invertebrate interaction information for the Atlantic Forest, a South American tropical forest domain. Data were obtained from published works and "gray literature," such as theses and dissertations, as well as self-reports by co-authors. The data set has ~18,000 interaction records forming 482 networks, each containing between one and 1061 interaction links. Each network was sampled for about 200 h or less, with few exceptions. A total of 641 plant genera within 136 different families and 39 orders were reported, with the most abundant and rich families being Asteraceae, Fabaceae, and Rubiaceae. Invertebrates interacting with these plants were all arthropods from 10 orders, 129 families, and 581 genera, comprising 2419 morphotypes (including 988 named species). Hymenoptera was the most abundant and diverse order, with at least six times more records than the second-ranked order (Lepidoptera). The complete data set shows Hymenoptera interacting with all plant orders and also shows Diptera, Lepidoptera, Coleoptera, and Hemiptera to be important nodes. Among plants, Asterales and Fabales had the highest number of interactions. The best sampled environment was forest (~8000 records), followed by pastures and crops. Savanna, grasslands, and urban environments (among others) were also reported, indicating a wide range of approaches dedicated to collecting flower-invertebrate interaction data in the Atlantic Forest domain. Nevertheless, most reported data were from forest understory or lower strata, indicating a knowledge gap about flower-invertebrate interactions at the canopy. Also, access to remote regions remains a limitation, generating sampling bias across the geographical range of the Atlantic Forest. Future studies in these continuous and hard-to-access forested areas will yield important new information regarding the interactions between flowers and invertebrates in the Atlantic Forest. There are no copyright restrictions on the data set. Please cite this data paper if the data are used in publications and teaching events.
