Ecology and Evolution, Volume 9, Issue 3, Page 1410-1430, February 2019., 2019 Predator–prey relationships are important ecological interactions, affecting biotic community composition and energy flow through a system. This study used sequences from the 18S V9 rRNA barcoding region to identify prey items in the gastrointestinal (GI) tracts of predators taken from the Black River, Cheboygan Co., MI (n = 367 samples, 12 predator ...

Observations on the Nesting of \u3ci\u3eCrabro Tenuis\u3c/i\u3e (Hymenoptera: Sphecidae) [PDF]
, 2017 Three nests of Crabro tenuis were studied during June 1971-1972 in Oswego County, New York. Females constructed shallow but lengthy, multicelled nests in sand with the cells being built in clusters, sometimes in series. Females plugged the entrances with

International Journal of Ecology, Volume 2014, Issue 1, 2014., 2014 Aquatic environments are being modified by anthropogenic activities regarding their biological, physical, and chemical conditions; even pristine aquatic ecosystems can be threatened. This study focused on the biological monitoring of Maroaga Stream—a first order stream located in an Environmental Protection Area in the Amazon using the Biological ...

Biological Invasion and Coexistence in Intraguild Predation
Journal of Applied Mathematics, Volume 2013, Issue 1, 2013., 2013 Invasion of an exotic species initiated by its local introduction is considered subject to intraguild predation (IGP). Mathematically, the system dynamics is described by three nonlinear diffusion‐reaction equations in two spatial dimensions. The key factors that determine successful invasion are investigated by means of extensive numerical simulations.

Integrating eDNA and community science to monitor urban Odonata diversity
Insect Conservation and Diversity, Volume 19, Issue 1, Page 84-92, January 2026.Environmental DNA captured rare and underrepresented taxa often missed by community science observations. Community science revealed adult‐stage observations across a broader temporal window. Integrating both methods improved detection across life stages, seasons, and species prevalence.

Aquatic biosurvey of the Lovell River on UNH land [PDF]
, 2003 We assessed the physical, chemical and biological conditions at two sites along the Lovell River on University of New Hampshire (UNH) -owned conservation land. The discharge was 4.4 m3 s-1 at Site 1 and 5.7 m3 s -1 downstream at Site 2.

Freshwater Biology, Volume 70, Issue 7, July 2025.ABSTRACT Aquatic insects are an abundant, yet declining, taxonomically heterogeneous group with special importance in both aquatic and terrestrial ecosystems. Accurate estimations of insect biomass during their aquatic life stages are essential to advance our fundamental knowledge about insects, their roles in ecosystems, and their vulnerability to ...

Stream Invertebrate Responses to Fine Sediment Depend on the Organic and Inorganic Components
Freshwater Biology, Volume 70, Issue 3, March 2025.ABSTRACT Excess fine sediment ( < 2 mm) is a pervasive stressor of aquatic systems at a global scale. To date, most research quantifying ecological response to deposited fine sediment has been conducted without distinguishing between the organic and inorganic components of fine sediment, leaving mechanistic understanding of how fine sediment affects ...
